SYSTEMS AND PROCEDURE FOR SELECTIVE USE OF ILLUMINATION COLOR FOR RECORDING SUITABLE DATA POSSIBLE
BACKGROUND OF THE INVENTION Biopsy scanners have long been used to capture barcode (barcode) data and then use it to look up the price of the scanned item. Barcode (barcode) scanning is traditionally performed with monochromatic image processing. In other words, both the camera and the illumination source operate within a narrow bandwidth of the electromagnetic spectrum. Lasers are commonly used as the illumination source to achieve this narrow bandwidth. Barcode (barcode) scanning with monochrome image processing is cost-effective and, for historical reasons, has traditionally been performed in the red region of the visible electromagnetic spectrum. However, although bioptic scanners started out as laser-based systems, they have evolved into digital or camera-based systems.
Digital or camera based image processors can be used for item recognition purposes. However, unlike barcode (barcode) scanning, item recognition is usually performed with multicolored image processing. In other words, both the camera and the illumination source operate within a wide range of the visible spectrum.

DETAILED DESCRIPTION Traditional biopsy barcode readers do not have the capability to perform both monochrome and multicolor image processing. Accordingly, there is a need for solutions that solve problems related to scanners that cannot provide both monochromatic and multicolor illumination for a monochrome camera and a color camera, respectively.
In various embodiments of the present disclosure, a biopsy bar code reader, and related methods are described for selectively using illumination color to record appropriate data. The bioptic bar code reader and related methods of the present disclosure provide solutions where, for example, a bioptic bar code reader is required to capture both the bar code (bar code) and object image data.
For example, when the bioptic barcode activates to record barcode data, the monochromatic barcode reader may not be able to register a barcode (barcode), for example, a product without a barcode. In various embodiments, the disclosure of the present application describes a multicolor image processing system configured to capture color images of objects for analysis after the monochromatic barcode image processing process has failed to produce barcode data. The color images can be sent to a central computer for analysis to provide product identification despite the lack of a barcode. In this manner, the disclosure of the present application provides point-of-sale sales personnel and others with the ability to identify and accurately price products without barcodes.
Other benefits can be gained from the combined monochromatic and color image processing of the bioptic barcode reader.
For example, the bioptic bar code reader of the present application can be used to detect when an object has passed through the bioptic bar code reader without being processed.
The biopsy bar code reader of the present invention can then alert store personnel that a theft event is occurring.
Additionally, the bar code reader of the present application can be used to detect when a processed bar code has been incorrectly applied to a product with the intention of purchasing the product at a lower price, with others being 'swapped'. The bar code reader of the present invention would sense and activate an object passing through its optical field of view (FOV) to record the bar code.
After capturing the barcode, the multi-color image processing system of the biopsy barcode reader would activate to capture a color image of the product.
The biopsy bar code reader of the present invention, upon comparison, would detect a mismatch between the product identified from the color image and the product identified from the displayed bar code (bar code). The bar code reader of the present application can then warn store personnel that the processed bar code has been incorrectly applied to the processed product.

In certain embodiments, the primary lighting assembly 108 operates in an on state and an off state. In these embodiments, the primary lighting assembly 108 is optimized for reading the one or more barcodes in the turned on state.
For example, the primary image processing assembly 104, 106 may activate to capture the one or more first images during the first period of time. Accordingly, the primary illumination assembly 108 may radiate the primary illumination through a substantially vertical image processing window 110 and/or a substantially horizontal image processing window 112 of the biopsy bar code reader 100. The primary illumination assembly 108 may begin to radiate the primary illumination for the first period of time, and may continue to radiate the primary illumination until the end, before the end, or after the end of the first period of time. Similarly, the primary lighting assembly 108 may begin radiating the primary lighting after the beginning of the first period of time, and may stop radiating the primary lighting before the end, until the end, or after the end of the first period of time. . Further, and as will also be discussed further herein, the primary lighting assembly 108 may emit the primary lighting at intervals (e.g., lighting pulses) before, during, and/or after the first period of time, but during at least a portion of the first period of time.
The primary illumination has a primary illumination wavelength range. In certain embodiments, the primary illumination is monochromatic illumination, and the primary illumination wavelength range is in the near infrared spectrum or in any other suitable wavelength range for scanning 1D or 2D images, including white light.
The substantially vertical image processing window 110 and the substantially horizontal image processing window 112 define an optical FOV for the bioptic bar code reader 100. This optical FOV may, for example, allow the bioptic bar code reader 100 to scan five or more sides of any object passing through the optical FOV.
As further described herein, the biopsy bar code reader 100 can be configured to activate automatically when an object enters the optical FOV. In certain embodiments, once the object enters the optical FOV, the primary illumination assembly 108 may activate to emit the primary illumination through the substantially vertical image processing window 110. The primary imaging assembly 104, 106 may then activate to capture an image of the object. lay. It will be appreciated, however, that activation of the biopsy bar code reader 100 may not be automatic when an object enters the optical FOV. Activation of the biopsy bar code reader 100 can occur by any suitable means, including manual activation.
Accordingly, activation of the bioptic bar code reader 100, e.g., by an object entering the optical FOV, may prompt the bioptic bar code reader 100 to capture image data. Such image data may include, for example, product codes (such as barcodes and QR codes) associated with corresponding products as well as visual images of the product being scanned, as further described herein.
fig. 1B illustrates an exploded view of the exemplary biopsy bar code reader 100 of FIG. 1A in accordance with various embodiments regarding selective use of illumination color to record appropriate data as disclosed herein. Bioptic barcode reader 100 includes a secondary image processing assembly 116 including one or more secondary image processors. The one or more secondary image processors are configured to capture one or more secondary images of the target object. The one or more secondary image processors are further configured to capture the one or more second images during a second period of time. In certain embodiments, the secondary image processing assembly 116 is a color camera positioned on an area above the surface of the POS station. In other embodiments, secondary image processing assembly 116 is positioned external to the housing (e.g., housing 102).
In certain embodiments, the one or more secondary image processors are configured to capture the one or more secondary images of the one or more target objects when the primary lighting assembly 108 is in an on or off state. For example, the one or more secondary image processors may be configured to capture the one or more secondary images while the primary lighting assembly 108 is in an on state (in other words, emitting primary lighting), or using only ambient light (in other words , without the primary lighting). To illustrate, when a user wishes to purchase a fruit piece, the user will run any barcode(s) affixed to or otherwise associated with the fruit piece through the FOV of the biopsy barcode reader 100 . When the fruit piece passes through the FOV of the biopsy bar code reader 100, the primary image processing assembly 104, 106 will activate to capture the one or more first images of the one or more barcodes of the fruit piece, and the primary illumination assembly 108 will illuminate the emit primary lighting (in other words, operate in the on state). The secondary image processing assembly will then activate to capture the one or more second images of the fruit. Accordingly, the secondary image processing assembly will activate while the primary illumination assembly 108 is still radiating the primary illumination, or may activate after the primary illumination assembly has stopped radiating the primary illumination. The second time period is subsequent to or partially overlaps with the first time period. Thus, the secondary image processing assembly 116 is configured to capture the one or more second images of the target objects after the primary image processing assembly 104, 106 has captured the one or more first images of the barcode associated with the target object.
For example, and in certain embodiments, the first time period and the second time period comprise a duty cycle. Further, in this example, the first time period includes a first portion of the duty cycle, and the second time period includes a second portion of the duty cycle. The primary image processing assembly 104, 106 and the secondary image processing assembly 116 may be active for the same period of time, and thus each may comprise one half of the duty cycle of the biopsy bar code reader 100 . However, the secondary image processing assembly 116 and the primary image processing assembly 104, 106 may be active for unequal periods of time, thus comprising unequal portions of the duty cycle of the biopsy bar code reader 100.
The secondary image processing assembly 116 may additionally be configured to capture a landscape and/or portrait image of the target object during the second period of time. For example, the secondary image processing assembly 116 in a landscape orientation may be able to capture the one or more second images of the target object with a wide horizontal field of view (FOV) (e.g., horizontal FO of >70 degrees) over the biopsy barcode reader 100 image processing surface. Similarly, the secondary image processing assembly 116 in a portrait orientation may be able to capture the one or more second images of the target object with a wide vertical FOV (e.g., a vertical FOV of -70 degrees) over the bioptic barcode reader 100 image processing surface. .
In certain embodiments, the secondary image processing assembly 116 may be configured to activate when a target object enters the optical FOV of the biopsy bar code reader 100. It will be appreciated that the secondary imaging assembly 116 may be configured to activate before the primary image processing assembly 104, 106.
The data or information captured from both the primary image processing assembly 1104, 106 and/or the secondary image processing assembly 116 may be sent to POS stations, servers, or other processing devices for various purposes, including, for example, product purchases, data storage, inventory purposes, etc.
Biopsy barcode reader 100 further includes a secondary image processing assembly holder 118 and a second image processing assembly aperture 120. The secondary imaging assembly holder 118 is designed to couple the secondary imaging assembly assembly 116 to the secondary imaging assembly aperture 120. The secondary imaging assembly holder 118 and the secondary image processing assembly aperture 120 places the secondary image processing assembly 116 in a position to capture images of the one or more second images of the target object. In certain embodiments, the secondary image processing assembly holder 118 may be adjustable between portrait and landscape orientations, as described herein.
The biopsy bar code reader 100 further includes an adjustable outer cover 122. The adjustable outer cover 122 may be part of the housing 102, and may be detachable from the remainder of the biopsy bar code reader 100. For example, in certain embodiments, when portrait oriented images are desired. , the adjustable outer cover 122 can be removed, and the secondary image processing assembly holder 118 can be adjusted to facilitate the secondary image processing assembly 116 to capture the one or more second images in a portrait orientation.
FIG. 2 illustrates a cross-sectional view of the exemplary barcode reader of FIG. 1A in accordance with various embodiments regarding selective use of illumination color to record appropriate data disclosed herein. Bioptic barcode reader 100 includes primary illumination assembly 108 and secondary illumination assembly 204. Secondary illumination assembly 204 is configured to emit secondary illumination during at least a portion of the second period of time. The secondary illumination has a secondary illumination wavelength range, which is different from the primary illumination wavelength range of the primary illumination radiated from the primary illumination assembly 108. In certain embodiments, the secondary illumination assembly 204 is positioned external to the housing (e.g., housing 102).
In certain embodiments, the secondary illumination is multicolor illumination. In these embodiments, the secondary wavelength range comprises a composition of wavelengths sufficient to create substantially white light. For example, the secondary wavelength range may comprise a composite of light from the blue and yellow ranges of the visible spectrum to create a type of substantially white light.
The biopsy bar code reader 100 illustrated in FIG. 2 further includes a secondary controller 208 configured to control the secondary lighting of the secondary lighting assembly 204 .
The secondary controller 208 is separate from the primary controller 206. For example, the secondary controller 208 may activate the secondary lighting assembly 204 after the primary controller 206 is activated and the primary lighting assembly 108 is deactivated. In certain embodiments, the secondary controller 208 may activate the secondary lighting assembly 204 when the target object enters the optical FOV. In other embodiments, primary controller 206 and secondary controller 208 may activate primary lighting assembly 108 and secondary lighting assembly 204 simultaneously.
In certain embodiments, the biopsy bar code reader 100 may include a controller configured to sequentially capture (1) a plurality of primary images of the one or more barcodes with the primary image processing assembly and (ii) a plurality of the one or more images with the secondary image processing assembly, wherein the plurality of primary images of the one or more barcodes are sequential between the plurality of the one or more secondary images. For example, the biopsy bar code reader 100 may take a sequence of the one or more first images and the one or more second images in a staggered fashion, wherein the recording of the one or more first images is sequentially followed by the recording of one of the or more second images, and so on. For example, in these embodiments, the primary controller 206 or the secondary controller 208, alone or in combination, can perform this function.
In addition, in these embodiments, the controller is further configured to generate a trigger signal to the secondary image processing assembly 116 to enable functionality of the second image processing assembly 116 to capture the plurality of the one or more secondary images. For example, the controller may receive a signal from primary image processing assembly 104, 106 indicating that primary image processing assembly 104, 106 has captured one of the one or more first images. Alternatively, the controller may also monitor a threshold (e.g., the first period of time) associated with the primary image processing assembly 104, 106 that captures one of the one or more first images. When the controller senses that the primary image processing assembly has exceeded a threshold (for example, the controller has not received a signal indicating a successful capture of one or more first images during or after the first period of time), the controller may generate a trigger signal.
Bioptic barcode reader 100 illustrated in FIG. 2 further includes a monitoring circuit 202 communicatively coupled to the primary controller 206 and the secondary controller 208. As further described herein, after the primary controller 206 turns off the primary lighting assembly 108, the primary controller 206 sends a primary signal to the monitoring circuit 202. primary signal indicates to monitoring circuit 202 that primary lighting assembly 108 is turned off. The monitor circuit 202 then generates and sends a secondary signal to the secondary controller 208 to indicate that the secondary lighting source 204 is to be activated. Finally, upon receipt of the secondary signal, the secondary controller 208 activates the secondary illumination source 204. Thus, the secondary signal is subsequent to the primary signal.
FIG. 3 illustrates a method of using the exemplary biopsy bar code reader 100 for selective use of illumination color to record appropriate data in accordance with various embodiments disclosed herein. Method 300 begins at block 302 where, for example, the primary illumination assembly 108 emits the primary illumination, which has a primary wavelength range, during at least a portion of a first period of time. For example, as discussed herein, the primary lighting assembly 108 may begin emitting the primary lighting before and during the first period of time, and may stop emitting the primary lighting before the end, at the end, or after the end of the first period of time. time period.
As mentioned with respect to FIG. 1A, the primary lighting assembly 108 may emit the primary lighting at intervals (e.g., lighting pulses) before, during, and/or after the first period of time, but during at least a portion of the first period of time. For example, if the first period of time is 1 second, the primary lighting assembly 108 may emit the primary lighting at intervals before, times, and/or after that one second. By way of illustration, the primary lighting assembly 108 may emit a first lighting pulse at the beginning of the 1 second of the first time period. The first illumination pulse may last for 10 milliseconds (ms) such that there is 990 milliseconds of the first period of time remaining after the first illumination pulse. Thus, the primary illumination assembly 108 may then emit a second 10 ms illumination pulse after 400 ms of the first time period has elapsed, such that 590 ms of the first time period remains after the second illumination pulse. At block 304, the method 300 includes capturing the one or more first images of a bar code (barcode) associated with the target object during the first period of time with the primary image processing assembly 104, 106 including the one or more primary image processors positioned within the housing. The barcode associated with the target object may be one or more barcodes, and the barcode may not be attached to the target object. For example, if a user wishes to purchase an item that is log or otherwise cannot be brought to the POS station, the user may take one or more barcodes associated with that item to the POS station to make the purchase. At block 306, method 300 includes radiating the secondary illumination having the secondary wavelength range during at least a portion of the second period of time. The secondary lighting is emitted from the secondary lighting assembly 204.
At block 308, method 300 includes capturing the one or more second images of the target object during the second period of time with the secondary image processing assembly 116 including one or more secondary image processors. Returning to the fruit example described herein, the user may place the piece of fruit in the POV of the biopsy bar code reader 100 in an attempt to scan one or more bar codes that may be applied to the surface of the fruit.
However, if the piece of fruit does not have a decipherable barcode (for example, the barcode of the piece of fruit is unclear, damaged, or otherwise illegible, or the piece of fruit has no barcode at all), the first image(s) will not identify the fruit, and the user will not complete his transaction.
Thus, the one or more second images captured by the secondary image processing assembly 116 will still positively identify the fruit based on image analysis of the visual appearance of the fruit. Simply put, the biopsy barcode reader 100 can identify the target object by image analysis (i.e., machine learning, neural networks, etc.) when the target object does not have a decipherable barcode.
Additional embodiments, features, or functionalities may also be implemented for method 300 in accordance with the description herein for the biopsy bar code reader 100 or as described elsewhere herein. Further, the functions and operations shown in FIG. 3 may be performed in any suitable order, for any desired number of times, and/or with any suitable variation on the particular sequence and/or combination shown to achieve a desired result, such as a desired mode of operation with a biopsy bar code reader.
Camera systems are increasingly being implemented in POS stations. These systems are mainly sought after for their machine vision applications (e.g., fruit identification, AR database building, etc.) and anti-theft applications (e.g., sweathearting, ticket exchange, etc.). Ideally, a camera system for these applications is placed so that it can view objects crossing the plate of a bioptic scanner at a POS.
However, this can be a problem since the bioptic scanners use a blinking illumination that alternates to match the image processing sensor frames for each field of view.
This can be especially problematic in machine vision applications, as it can create flashes that blind the camera, critical lighting spots on the item, or in the case of red lighting, alter the color appearance of the item in question. This creates a host of issues that prevent a customer from using a camera that is not fully integrated with whatever biopsy scanning system is being used.
FIG. 4 illustrates an exemplary system 400 for synchronizing illumination for an auxiliary camera of a biopsy bar code reader. The exemplary system 400 includes a barcode reader 402 and an external image processing device 404. The external image processing device 404 may be any suitable image processing device (e.g., camera, video camera, IR sensor, depth sensor, etc.).
Barcode reader 402 includes a housing 406, a primary image processing assembly 408, a primary lighting assembly 410, a controller 412, and an external device interface 414. Both the primary image processing assembly 408 and the primary lighting assembly 410 are positioned within the housing 406. device interface
414 is positioned at least partially within the housing, and the controller 412 may be positioned wholly within, partly within, or wholly outside the housing.
The primary image processing assembly 408 is configured to capture a plurality of images of an environment appearing within a FOV of the primary image processing assembly 408 . The plurality of images may all be captured sequentially or, as further described herein, may be arranged according to signals sent from the controller 412. The environment that appears within the FOV of the primary image processing assembly 408 may further include a target object. For example, a user may attempt to purchase an item at a POS station by passing the item through the FOV of the primary image processing assembly 408 . The primary image processing assembly 408 may then capture a plurality of images of the environment appearing within its FOV, including the target object.
The primary image processing assembly 408 is further configured to capture a plurality of images at a predetermined frame rate. For example, the primary image processing assembly may be configured to capture the plurality of images at a frame rate of 60 frames per second (fps). As discussed further herein, this predetermined frame rate may be communicated to the primary image processing assembly 408, for example by the controller 412.
In certain embodiments, the primary image processing assembly 408 may include one or more primary image processors. The one or more image processors may be configured to capture a plurality of first images of the environment that appears within the FOV during a scanning session. The scanning session includes one or more frames, and the one or more primary image processors capture each of the plurality of first images during a respective first duration of each of the one or more frames of the scanning session. In these embodiments, the primary image processing assembly 408 is also configured to capture the plurality of first images at a predetermined frame rate.
The primary illumination assembly 410 is configured to provide primary illumination over at least a portion of the environment appearing within the FOV of the primary imaging assembly 408. The primary illumination may be composed of any combination of wavelengths of light effective to illuminate the primary imaging assembly 408. to capture the multiple number of images. For example, the primary lighting may be multicolored lighting, such as a composite of wavelengths suitable to create substantially white light. Illustratively, the primary illumination may comprise a composite of light from the blue and yellow ranges of the visible spectrum to create a type of substantially white light. In another example, the primary illumination may be monochromatic illumination, such as light from the red range of the visible spectrum.
Additionally, the at least a portion of the environment that appears within the FOV of the primary image processing assembly 408 may be any portion sufficient to allow the primary image processing assembly 408 to capture the plurality of images. For example, the at least a portion of the environment may include the portion of the environment that, as further described herein, includes a target object. Illustratively, if a user attempts to purchase an item from a POS station by passing the item through the FOV of the primary image processing assembly 408, the primary lighting assembly 410 may provide the primary illumination over the portion of the FOV such that the item is fully or partially lit by the primary lighting.
In certain embodiments, the primary lighting assembly 410 is configured to provide the primary lighting to at least a portion of the environment, the primary lighting assembly providing the primary lighting as a series of primary lighting pulses. The sequence of primary illumination pulses is emitted for a respective second duration of each of the one or more frames of the scan session. Moreover, the respective second duration differs from the respective first duration in these embodiments.
The controller 412 is communicatively coupled to the primary image processing assembly 408, the primary lighting assembly 410, and the external device interface 414. The controller 412 also includes a processor 416 and a memory 418. (Although referred to herein as a "processor" and a "memory", it will be understood that a processor may be one or more processors, and a memory may be one or more memories).
Memory 418 stores instructions which, when executed by processor 416, prompt controller 412 to transmit an image capture signal to primary image processing assembly 408. The image capture signal prompts primary image processing assembly 408 to process a series of primary capture picture frames. Each of the series of primary images is captured for a respective first duration D1. Each of the sequence of primary image frames is separated from another of the sequence of primary image frames by a respective second dur D2. A beginning of each of the sequence of primary image frames is separated from a beginning of each successive of the sequence of primary image frames by a third duration D3.
To illustrate, the respective first duration, D1, is the duration when the primary image processing assembly 408 captures a series of primary image frames.
After the respective first duration, the primary image processing assembly 408 stops capturing the sequence of primary image frames for a respective duration, D2. After the respective second duration, the primary image processing assembly 408 has reached a successive respective first duration, D1, during which the primary image processing assembly 408 captures another set of primary image frames.
The combination of the respective first duration, D1, and the respective second duration, D2, is encapsulated in the respective third duration, D3, which defines the total separation between each of the series of primary image frames.
Memory 408 stores instructions that, when executed by the processor, further prompt the controller to transmit a primary lighting-on signal to primary lighting assembly 410. The primary lighting-on signal prompts primary lighting assembly 410 to emitting the primary lighting.
The primary illumination has a series of primary illumination pulses, and each of the series of primary illumination pulses is radiated for a respective fourth duration D4. Each of the sequence of primary illumination pulses is separated from another of the sequence of primary illumination pulses by a respective fifth duration D5. It will be appreciated that in various embodiments, the controller 412 may transfer the primary lighting-on signal to the primary lighting assembly 410 before or after the controller 412 transfers the image capture signal to the primary image processing assembly 408. By way of illustration, the respective duration D4, the duration when the primary lighting assembly 410 emits a series of primary lighting pulses.
After the respective fourth duration, the primary lighting assembly 410 stops emitting the primary lighting pulses for the respective fifth duration, D5. After the respective fifth duration, the primary lighting assembly 410 has reached a successive respective fourth duration, D4, during which the primary lighting assembly 410 emits another series of primary lighting pulses.
In certain embodiments, the respective first duration D1 is equal to the respective fourth duration D4. For example, in these embodiments, primary image processing assembly 408 will capture a series of primary image frames for the same amount of time that primary lighting assembly 410 will emit a series of primary lighting pulses. In this manner, the primary image processing assembly 408 will capture each of the sequence of primary image frames with primary illumination from the primary illumination assembly 410.
Similarly, in these embodiments, the respective second duration D2 is equal to the respective fifth duration D5. For example, in these embodiments, the primary image processing assembly 408 will stop capturing a series of primary image frames for the same amount of time that the primary illumination assembly 410 will stop emitting the primary illumination pulses. In this manner, the primary illumination assembly 410 will not provide primary illumination pulses for a duration when the primary image processing assembly 408 does not capture a series of primary image frames (i.e., when the primary illumination pulses would be redundant).
In certain embodiments, when executed by the processor 416, the instructions further prompt the controller 412 to transmit the image capture signal to the primary image processing assembly 408 to prompt the primary image processing assembly 408 to capture the sequence of primary images. picture frames. Each of the sequence of primary image frames is captured for a respective first duration. Further, in these embodiments, when executed by the processor 416, the instructions cause the controller 412 to transmit the primary lighting-on signal to cause the primary lighting assembly 410 to emit the primary lighting for the respective second duration. . Still further in these embodiments, when executed by processor 416, the instructions cause controller 412 to transmit, substantially simultaneously with transmitting the primary light-on signal, an interleaved signal to the external device. interface 414. The interleaving signal is operable to communicate, through the external device interface 414, at least one feature associated with at least one of the primary light-on signal and the image capture signal. In addition, the controller 412 may iteratively execute outputting the primary lighting-on signal, outputting the image capture signal, and transmitting the interleaving signal for each respective frame of the scanning station.
Further, in certain embodiments, when executed by processor 416, the instructions cause the controller 412 to transmit the image capture signal to the primary image processing assembly 408 before the controller transmits the primary lighting-on signal to the primary lighting assembly 410. Further, in other embodiments, when executed by the processor 416, the instructions cause the controller 412 to transfer the primary lighting-on signal to the primary lighting assembly 410 and simultaneously transfers the image capture signal to the primary image processing assembly 408 .
The memory 418 stores instructions which, when executed by the processor 416, further prompt the controller 412 to transmit, substantially simultaneously with the transmission of the primary-light-on signal, an interleaved signal to the external device interface.
414. The interleaving signal is operable to communicate, through the external device interface 414, at least one feature associated with at least one of the primary light-on and the image capture signal.
Illustratively, the controller 412 may transfer the interleaving signal to the external device interface 414 to provide information to the external image processing device 404. The controller 412 may further transmit the interleaving signal substantially simultaneously with the transmission of a primary illumination. -on signal to provide the information to the external image processing device 404 as quickly as possible.
For example, if the external imaging device 404 is a camera, by thus providing information to the external imaging device 404, the interleaving signal enables the external imaging device 404 to synchronize the captured frames from the external imaging device 404 between illumination flashes from the barcode reader 402 through (ie, the series of lighting pulses radiated from the primary lighting assembly 410). In other words, the interleaving signal enables the external image processing device 404 to limit the exposures of the external image processing device 404 to prevent the sequence of primary illumination pulses from saturating or otherwise affecting the exposures of the external image processing device.
In certain embodiments, the at least one feature is at least a length one of a length of (1) the respective first duration D1, (1) the respective second duration D2, (ii) the respective third duration (D3), (iv) the respective fourth duration (D4), and (v) the respective fifth duration D5. For example, the at least one characteristic may be the length of the respective first duration D1 such that the interleaving signal communicates the length of the signal when the primary image processing assembly 408 captures a series of primary image frames. This would allow the external image processing device 404 to, for example, limit the exposures of the external image processing device 404 to durations when the primary image processing assembly 408 stops capturing the sequence of primary image frames (e.g., the respective duration D2). Alternatively, the external image processing device 404 may use the length of the respective first duration D1 to purposely limit the exposures of the external image processing device 404 to the respective first duration D1. For example, if the external imaging device 4040 uses the same illumination as the primary image processing assembly 408, the external imaging device 404 can take advantage of that fact by exposing the external imaging device 404 at the same time as the primary imaging assembly 408.
In another example, the at least one characteristic may be the length of the respective second duration D2 such that the interleaving signal is the length of the duration over which each of the sequence of primary image frames is separated from another of the sequence of primary image frames. Similarly to the length of the respective first duration, transferring the length of the respective second duration would allow the external image processing device 404 to limit, for example, the exposures of the external image processing device 404 when the primary image processing assembly stops capturing. of the set of primary image frames.
In another example, the at least one characteristic may be the length of the respective third duration D3 such that the interleaving signal communicates the length of the duration by which the beginning of each of the sequence of primary image frames is separated from a beginning of each of the successive of the set of primary image frames. Transferring the respective third duration would allow the external image processing device 404 to limit, for example, the exposure of the external image processing device 404 based on the length of the total duration of each primary image frame.
In another example, the at least one characteristic may be the length of the respective fourth duration D4 such that the interleaving signal communicates the length of the duration over which the primary lighting assembly 410 radiates a series of lighting pulses. This would allow the external image processing device 404 to limit, for example, the exposures of the external image processing device 404 when the primary lighting assembly 410 stops emitting the sequence of primary lighting pulses. If the external image processing device 4040 is configured to capture images with a form of light other than that provided by the primary lighting assembly 410, then the external image processing device 404 may limit its exposure to durations in the primary image frame other than the respective fourth duration.
In another example, the at least one characteristic may be the length of the respective fifth duration D5 such that the interleaving signal communicates the length of duration over which each of the sequence of primary illumination pulses is separated from another of the sequence of primary illumination pulses. Transferring the respective fifth duration would enable the external image processing device 404 to limit, for example, the exposures of the external image processing device 404 to durations in the primary image frame including all or part of the fifth duration.
Owners of a biopsy scanner may wish to integrate a color camera to accomplish various tasks. This includes: product recognition to build a neural network database, vegetable identification for easier self-checkout, sweetheart grabbing and ticket switching. To best serve these purposes, it is desirable to have a color camera with a good
FOV coverage over, above and to the sides of the plate area.
Thus, a larger FOV is generally desirable.
However, the greater the required FOV becomes, the fewer locations are available to position the color camera relative to the bioptic.
In addition, a larger FOV combined with a limited number of available locations can lead to other problems.
For example, if a single image processing system is unable to capture a full image of a target object, a composite image can be generated using image processing algorithms (eg image stitching). Traditional image stitching algorithms suffer from a lack of ability (or at least a lack of efficiency) to analyze and correctly stitch images of a particular item taken from different distances from the item.
FIG. 5A illustrates an exemplary biopsy bar code reader 500 having a stacked composition of a multicolor camera assembly and a monochromatic camera assembly.
The exemplary bar code reader 500 includes a housing 502. The biopsy bar code reader 500 further includes a primary image processing assembly 504, a primary illumination assembly 506, a controller 508, and a secondary image processing assembly (represented collectively by a first secondary image processor 510, and a second secondary image processor 512). . The primary image processing assembly 504 includes one or more primary image processors, each positioned within the housing 502 .
Each of the one or more primary image processors is configured to capture one or more first images from one or more barcodes of one or more target objects.
The primary lighting assembly 506 is positioned within the housing 502, and is operable in an on state and an off state. The primary illumination assembly 506 is configured to emit primary illumination optimized for capturing the first image(s) of the one or more barcodes in the on state. For example, when turned on, the primary lighting assembly 506 may emit the primary lighting as a combination of different wavelengths of the visible spectrum (e.g., a combination of wavelengths to produce a substantially white light) or a monochromatic wavelength of the visible spectrum (eg, red light). In certain embodiments, the primary illumination assembly 506 emits primary illumination which is monochromatic illumination including nabi-infrared light.
The secondary image processing assembly 510, 512 is configured to capture one or more second images of the one or more target objects when the primary lighting assembly is in the on or off state. However, in certain embodiments, the secondary image processing assembly 510, 512 is configured to capture one or more second images of the one or more target objects only when the primary lighting assembly 506 is in the off state. The first secondary image processor 510 is positioned within the housing 502, and the first secondary image processor 510 has a first optical FOV 514, as shown in FIG. 5B.
The second secondary image processor 512 has a second optical FOV 516, as shown in FIG. 5B, and is positioned above the housing
502. Specifically, the second secondary image processor 512 is positioned above the housing 502 such that the first optical FOV 514 overlaps the second optical FOV 516 approximately equidistant from both the first secondary image processor 510 and the second secondary image processor 512. In certain embodiments, the second secondary image processor 512 is adaptably positioned above the housing 502.
By way of illustration and with reference to FIG. 5B, both the first optical FOV 514 and the second optical FOV 516 extend from both the first secondary image processor 510 and the second image processor 512. As the optical FOVs 515, 516 extend away from the secondary image processing assembly 510, 512, the optical FOVSs 514, 516 extend in both a vertical and horizontal (not shown) manner relative to the biopsy bar code reader 500.
Hence, the second secondary image processor 512 is positioned above the housing 502 such that when the optical FOVs 514, 516 extend away from the secondary image processor assembly 510, 512 and spread out, the optical FOVSs 514, 516 overlap at a point at approximately equal distance from both the first secondary image processor 510 and the second secondary image processor 512.
The positioning of the second secondary image processor 512 1s is advantageous because it allows more effective and efficient image stitching. For example, if a user wishes to purchase a large item (e.g., target object) from a POS station (e.g., bioptic barcode reader 500), the image processing equipment (e.g., secondary image processing assembly 510, 512) of the POS station can display multiple images (e.g., a or more second images) of the large item to get a complete view of the large item. Each of these multiple images will contain at least some different parts of the large item, and will then be combined (i.e. image stitching) to allow the POS station to analyze the complete image for item recognition purposes.
Because the second secondary image processor 512 is positioned above the housing 502 such that the optical FOVs 514, 516 overlap approximately equidistant from both parts of the secondary image processing assembly 510, 512, it will appear that the secondary image processing assembly 510, 512 processes the multiple images. captures from a perspective approximately equidistant from the large item. Merging the multiple images to produce a composite image of the large item is thus greatly improved as the stitching process can easily align similar parts of images without the need to resize or otherwise alter the images.
In certain embodiments, the housing 502 includes an upright scan tower 518. In these embodiments, the overlap of the first optical FOV 514 with the second optical FOV 516 occurs approximately near a top front corner of the upright scan tower 518. For example, and as illustrated in FIG. . 5B, the upright scan tower 518 includes at least primary lighting assembly 506, the first secondary image processor 510, and has edges defined by the housing 502. In this example, the "top" of the upright scan tower 518 is the portion of the upright scan tower 518 that is the second secondary image processor 512 is oriented, and "front" denotes a direction parallel to the direction in which the optical FOVS 514, 516 spread, as discussed herein.
FIG. 6A illustrates an exemplary biopsy bar code reader 600 with a deep inset assemblies of a multicolor camera assembly and a monochromatic camera assembly. The exemplary barcode reader 600 includes a housing 602. The housing 602 further includes a substantially horizontal image processing window 604 and a substantially vertical image processing window 606. The substantially horizontal image processing window 604 defines an image processing plane. In FIG. GB, the substantially vertical image processing window 606 includes a top edge 614 and a bottom edge 616.
The biopsy barcode reader 600 further includes a primary image processing assembly 608, a primary illumination assembly 610, and a secondary image processing assembly 612. The primary image processing assembly 608 includes one or more primary image processors (not shown) positioned within the housing 602. The one or more primary image processors are configured to capture one or more first images of one or more barcodes of one or more target objects.
The primary lighting assembly 610 is positioned within the housing, and is operable in an on state and an off state. The primary image processing assembly 610 is further configured to emit, when turned on, a primary illumination optimized for capturing the one or more first images of the one or more barcodes. For example, when turned on, the primary illumination assembly 610 may emit the primary illumination as a combination of different wavelengths of the visible spectrum (e.g., a combination of wavelengths to produce a substantially white light) or a monochromatic wavelength of the visible spectrum ( e.g., red light). In certain embodiments, the primary illumination is monochromatic light including near infrared light.
The secondary image processing assembly 612 includes one or more secondary image processors (not shown) configured to capture one or more second images of the one or more target objects when the primary lighting assembly is in the on or off state. However, in certain embodiments, the secondary image processing assembly 612 is configured to only capture one or more second images of the one or more target objects when the primary lighting assembly 610 is in a turned off state.
In addition, referring to FIG. 6B, the one or more secondary image processors of the secondary image processing assembly 612 include an optical FOV 612 through the vertical image processing window 606.
The secondary image processing assembly 612 is positioned within the housing 602 substantially linear to the image processing plane such that the optical FOV 618 extends substantially from the bottom edge 616 and substantially toward the top edge 614 of the substantially vertical image processing window 606 . In certain embodiments, the secondary image processing assembly 612 is adaptably positioned within the housing 602 substantially linearly with the image processing plane such that the optical FOV 618 extends at least from the bottom edge 616 toward the top edge 614 of the substantially vertical image processing window 606 .
The secondary image processing assembly 612 is as illustrated in FIG. GB positioned to provide a larger effective image processing area for the bioptic bar code reader 600. As an illustration, the bioptic bar code reader 600 has an effective image processing area based on the areas that the image processing assemblies 608, 612 can clearly see through the image processing windows 604, 606. The larger the effective image processing area of the bioptic bar code reader 600 becomes, the more effective the bioptic bar code reader 600 becomes at detecting and/or reading bar codes. Positioning the secondary image processing assembly 612 within the housing 602, as described above and as illustrated in FIG. GB, enlarged according to the area that the secondary image processing assembly 612 can view through the substantially vertical image processing assembly 606. When one or more target objects pass through the biopsy barcode reader 600 (e.g., a customer purchasing multiple items at a POS station), the one or more secondary image processors of the secondary image processing assembly 612 previously successfully capture the one or more second images of the one or more target objects. The positioning of secondary image processing assembly 612, as described above and as illustrated in FIG. 6B., thus obtains a more effective bioptic bar code reader 600 because it increases the effective image processing area of the bioptic bar code reader 600 .
FIG. 7A illustrates an exemplary composite system 700 of a biopsy bar code reader 702 and a color camera assembly (e.g., secondary image processing assembly 704). The biopsy bar code reader 702 includes a housing 706, which includes a scanning platform 708 and an upright scanning tower 710. The biopsy bar code reader 702 further includes a primary image processing assembly 712. The primary image processing assembly 712 includes one or more primary image processors (not shown). The one or more primary image processors are positioned within the housing 705, and are configured to capture one or more first images from one or more barcodes of one or more target objects.
The biopsy bar code reader 702 further includes a primary illumination assembly 714. The primary illumination assembly 714 is positioned within the housing 706 and is operable in an on and off state. The primary lighting assembly 714 is configured to emit, when turned on, primary lighting optimized for capturing the one or more first images of the one or more barcodes. For example, when turned on, the primary illumination assembly 714 may emit the primary illumination as a combination of different wavelengths of the visible spectrum (e.g., a combination of wavelengths to produce a substantially white light) or a monochromatic wavelength of the visible spectrum (e.g., ., Red light). In certain embodiments, the primary illumination is monochromatic light including near infrared light.
The biopsy bar code reader 702 further includes a controller 716. The controller 716 may be communicatively coupled to the primary image processing assembly 712, the primary illumination assembly 714, and the secondary image processing assembly 704.
The secondary image processing assembly 704 includes one or more secondary image processors. The one or more secondary image processors are configured to capture one or more second images of the one or more target objects when the primary lighting assembly 714 is in the on or off state. In certain embodiments, the one or more secondary image processors are configured to only capture one or more second images of the one or more target objects when the primary lighting assembly 714 is in the off state.
The secondary image processing assembly 704 is positioned above the bioptic bar code reader 702 to enhance the ability of the bioptic bar code reader 702 to capture images of items (e.g., the one or more target objects) when placed anywhere on the scanning platform 708. illustration, and referring to FIG. 7B, the one or more secondary image processors include an optical FOV
718. The secondary image processing assembly 704 is positioned above the biopsy bar code reader 702 such that the optical FOV 718 © encompasses the entire scanning platform 708 and (ii) is not obscured by the upright scanning tower 710. Thus, positioning the secondary image processing assembly 704 increases, as herein. discussed and as illustrated in FIG. 7B, the biopsy barcode reader's ability to capture images of items placed anywhere on the scanning platform 708 because the secondary image processing assembly 704 has an obscured optical FOV 718 that reaches the entire scanning platform 708 .
In certain embodiments, the secondary image processing assembly 704 is positioned above the bioptic bar code reader 702 by attaching the secondary processing assembly 704 to at least one of (1) a post attached to the bioptic bar code reader 702, (11) a post separate from the bioptic bar code reader 702, (iii) a support attached to the bioptic bar code reader 702, (iv) a support separate from the bioptic bar code reader 702, and (v) a display displaced above the bioptic bar code reader 702. Further, in these embodiments, the secondary image processing assembly 704 is adaptably positioned above the biopsy bar code reader 702.
For example, the secondary image processing assembly 704, as illustrated in FIG. 7C, positioned above the biopsy bar code reader 702 by attaching the secondary image processing assembly 704 to a pole 722 which is attached to the biopsy bar code reader 702. The pole 722 may be adjustable to allow the user to select an optimal position for the secondary image processing assembly 704 above the biopsy bar code reader 702. By way of illustration, one or more of the one or more target objects may be large objects that require significant vertical clearance to pass over the scanning platform 708 without contacting the secondary image processing assembly 704 or the optical FOV 718 to darken. Thus, a user can adjust the position of the secondary image processing assembly 704 above the biopsy bar code reader 702 (via the pole 722) such that the one or more target objects have room to pass over the scanning platform 708 without contacting the secondary image processing assembly 704 or to obscure the optical FOV 718.
fig. 8A illustrates another exemplary composite system 800 of a biopsy bar code reader 802 and a color camera assembly (e.g., secondary image processing assembly 804). The biopsy bar code reader 802 has a housing 806, which includes a substantially horizontal image processing window 808 and an upright scanning tower 810. The upright scanning tower 810 has a substantially vertical image processing window (not shown).
The biopsy bar code reader 802 further includes a primary image processing assembly 812. The primary image processing assembly 812 includes one or more primary image processors (not shown) positioned within the housing 806. The one or more primary image processors are configured to process one or more first images from one or more capture more barcodes of one or more target objects.
The biopsy bar code reader 802 further includes a primary lighting assembly 814 positioned within the housing 806. The primary lighting assembly 814 operates in an on and an off state. The primary lighting assembly 814 is additionally configured to emit, when turned on, primary lighting optimized for capturing the one or more first images of the one or more barcodes. For example, when turned on, the primary illumination assembly 814 may emit the primary illumination as a combination of different wavelengths of the visible spectrum (e.g., a combination of wavelengths to produce a substantially white light) or a monochromatic wavelength of the visible spectrum ( e.g., red light). In certain embodiments, the primary illumination is monochromatic light including near infrared light.
The biopsy bar code reader 802 further includes a controller 816. The controller 816 may be communicatively coupled to the primary image processing assembly 812, the primary illumination assembly 814, and the secondary image processing assembly 804.
The secondary image processing assembly 804 is configured to capture one or more second images of the one or more target objects when the primary lighting assembly 814 is in the on or off state. In certain embodiments, the secondary image processing assembly 804 is configured to only capture one or more second images of the one or more target objects when the primary lighting assembly 814 is in the off state. The secondary image processing assembly 804 includes a first secondary image processing assembly 818. The first secondary image processing assembly 818 is positioned at a first corner of the upright scanning tower 810 and in front of the substantially vertical image processing window. In addition, the first secondary image processor 818 has, as shown in FIG. 8B, a first optical FOV 822.
The secondary image processing assembly 804 includes a second secondary image processor 820, which has a second optical FOV 824, when viewed in conjunction with the first secondary image processor 818, positioned to enhance the view of the biopsy barcode reader 802 over the substantially horizontal image processing window 808. including areas beyond the substantially horizontal image processing window 808. Illustratively, the second secondary image processor 820 is positioned at a second corner of the upright scan tower 810 and in front of the substantially vertical image processing window such that an overlap of the first optical FOV 822 with the second optical FOV 824 occurs at least to the distal end of the substantially horizontal image processing window relative to the upright scanning tower 810. Positioning the secondary image processing assembly 804 in the manner described herein, and as illustrated in FIG. 8B, thus enhances the view of the biopsy barcode reader 802 over the substantially horizontal image processing window 808 because the optical FOVs 822, 824 overlap at least to the distal (e.g., far) end of the substantially horizontal image processing window 808 relative to the upright scanning tower 810 .
Additionally, this positioning increases the view of the biopsy bar code reader 802 over an area beyond the substantially vertical image processing window 808. For example, a POS station may have a conveyor belt leading to the biopsy bar code reader 802 to bring one or more target objects closer to the biopsy bar code reader 802. , so that the one or more target objects can be scanned, displayed, or otherwise identified. Similarly, the POS station may also have a packing area on the opposite side of the conveyor, so that the one or more target objects can be packed after they have been identified. Thus, positioning the secondary image processing assembly 804 may increase the view of the biopsy bar code reader 802 over areas beyond the substantially horizontal image processing window 808 because, as illustrated in FIG. 8B, the optical FOVs 822, 824 extend into areas adjacent to the substantially horizontal image processing window 808 (e.g., a conveyor belt, a wrapping area, etc.). With improved visibility over the areas beyond the substantially horizontal image processing window 808, the biopsy barcode reader 802 can more effectively identify, track, or otherwise indicate an item that was not scanned by the cashier, was intentionally stolen, or was the subject of sweethearting.
In certain embodiments, housing 806 further includes a scanning platform (not shown). The scanning platform includes a substantially horizontal image processing window. In these embodiments, the overlap of the first optical FOV 822 with the second optical FOV 824 occurs at least up to the distal end of the scanning platform.
In other embodiments, each of the first secondary image processor 818 or the second secondary image processor 820 is adaptably positioned on the upright scanning tower 810. Anti-theft devices are gaining popularity in many retail stores around the world, in part due to large inventory reductions. At POS stations, traditional practices involve installing anti-theft devices in the ceiling or some distance from the POS station. It is desirable to stamp the images obtained by an anti-theft system on a POS station with the decoding or time of the POS. However, if the anti-theft image processing apparatus is positioned away from the POS station, physically wiring the image processing apparatus to the POS system to obtain this stamp information is difficult. This added difficulty translates into additional cost and effort to install a POS anti-theft device. FIG. 9 illustrates a biopsy bar code reader system 900 in accordance with various embodiments described herein. The biopsy bar code reader system 900 includes one or more processors 902, a housing 904, a pole display 906, and a secondary image processing assembly 908. The pole display may be communicatively coupled to the one or more processors, with a primary image processing assembly 910, with a primary lighting assembly 912, with a controller 914, and with a secondary image processing assembly 908. For example, the pole display 906 can display the weight and cost of items (e.g., one or more target objects) weighed and identified by the biopsy bar code reader system
900. The biopsy bar code reader system 900 further includes the primary image processing assembly 910, which is positioned within the housing 904. The primary image processing assembly 910 includes one or more primary image processors (not shown) communicatively coupled to the one or more processors 902. one or more primary image processors are configured to capture one or more images of one or more barcodes from one or more target objects.
The biopsy bar code reader system 900 further includes a primary illumination assembly 912. The primary illumination assembly 912 is positioned within the housing 904 and is operable in an on and off state. The primary lighting assembly 912 is configured to emit, when turned on, primary lighting optimized for capturing the one or more first images of the one or more barcodes. For example, when turned on, the primary illumination assembly 912 may emit the primary illumination as a combination of different wavelengths of the visible spectrum (e.g., a combination of wavelengths to produce a substantially white light) or a monochromatic wavelength of the visible spectrum ( e.g., red light). In certain embodiments, the primary illumination is monochromatic light including near infrared light.
The biopsy bar code reader system 900 further includes controller 914. The controller 914 may be communicatively coupled to the primary image processing assembly 910, the primary illumination assembly 912, the pole display 906, and the secondary image processing assembly 908.
The secondary image processing assembly 908 includes one or more secondary image processors (not shown) configured to capture one or more second images of the one or more target objects when the primary lighting assembly 912 is in the on state or the off state. In certain embodiments, the secondary image processing assembly 908 is configured to only capture one or more second images of the one or more target objects when the primary lighting assembly 912 is in the off state.
The secondary image processing assembly 908 is mounted on the pole display 906, and is communicatively coupled to the one or more processors 902. In certain embodiments, the secondary image processing assembly is mounted within the pole display 906, and is communicatively coupled to the one or more processors 902. In addition, it is secondary image processing assembly 908 adaptively mounted 1s on the pole display 906. Mounting the secondary image processing assembly 908 on the pole display 906 and communicatively coupling the secondary image processing assembly 908 to the one or more processors 902 of the biopsy bar code reader system 900 increases the effectiveness of the POS anti-theft efforts significantly.
For example, the secondary image processing assembly 908 may associate the decryption and/or timestamp data from the biopsy bar code reader system 900 with the one or more captured second images of the one or more target objects by being communicatively coupled to the one or more processors 902 through the pole display 906. The secondary image processing assembly 908 would also be ideally located to monitor the contents of a shopping cart based on its location near the customer at the POS station.
For example, the secondary image processing assembly 908 may be directed to check the contents of a customer's shopping cart at the end of a sale to determine whether the shopping cart is empty.
Additionally or alternatively, the secondary image processing assembly 908 can be configured to determine whether each item in the customer's shopping cart has been bagged, as a final check to determine whether each item has actually been paid for.
The secondary image processing assembly 908 would further be ideally located to check items (e.g., one or more target objects) as they pass through the POS station.
The secondary image processing assembly
For example, 908 may be oriented to check items on a conveyor belt leading to and/or away from the biopsy bar code reader system 900. In this orientation, the secondary image processing assembly 908 may be configured to count the number of items that the FOV of the biopsy barcode reader system 900 enters and/or exits.
The secondary image processing assembly 908 may also be ideally located to identify potential "ticket switching" of items passed through the FOV of the biopsy bar code reader system 900 . For example, the secondary image processing assembly 908 may be positioned such that the one or more second images captured of a target object are sufficient to determine a mismatch between the product that has passed through the FOV of the biopsy bar code reader system 900 and the bar code that has been captured by the primary image processing assembly 910.
Bioptic systems use color cameras for a wide variety of object and gesture recognition at the point of sale. Ideally, such a camera is illuminated with white light to retain the best color information to aid in object identification. However, adding lighting in a bioptic vertical tower using traditional methods is extremely problematic, as it causes internal reflections that can be seen in the color camera's FOV. In addition, color cameras must have a very large FOV to see even the largest objects, so any lighting source placed in the vertical tower to cover such a large FOV will inevitably blind the user.
FIG. 10 illustrates a conventional biopsy scanning device 1000 using an internal color camera 1002 and an internal illumination source 1004, the internal illumination source 1004 interfering with the internal color camera 1002. The conventional bioptic scanning
device 1000 further includes a color camera FOV 1006, a scanning platform 1008, an internal illumination path 1010, a first image processing window 1012, and a second image processing window
1014.
The illumination radiated from the internal illumination source 1004 reflects from the image processing windows 1012, 1014, as illustrated by the internal illumination path 1010, into the color camera FOV 1006. This inadvertent illumination of the color camera's FOV 1006 distorts images captured by the internal color camera 1002, lowers the motion sensitivity of the internal color camera 1002, and may increase the exposure time of the internal color camera 1002 required to capture images of the object of interest. .
To solve these and other problems and referring to FIG. 11A, an illumination adapter 1100 for use with a biopsy bar code reader is disclosed. The lighting adapter 1100 includes one or more lighting components (not shown) that have an effective range. The lighting adapter 1100 further includes a first surface 1102 formed to receive the one or more lighting components, and a lower portion 1104 located below the one or more lighting components. In certain embodiments and as discussed further herein, the lighting adapter also includes one or more cavities 1106 and one or more baffles 1108. In other embodiments, the first surface 1102 is a first planar surface.
See also the lower portion 1104, the combined system 1120 illustrated in FIG. 11B, is adapted to releasably connect to the biopsy bar code reader 1122, and the one or more illumination components are positioned such that the effective range 1124 is both (i) unobscured by an upper flange 1126 of the biopsy bar code reader 1122 and (ii) at least a majority of a weighing platform 1128 of the biopsy bar code reader 1122 illuminated. In other embodiments, the lower portion 1104 is adapted to releasably connect to the barcode reader. In one embodiment, the lower portion 1104 is adapted to releasably connect to the barcode reader with at least one of (1) snap connections, Gi) double-sided adhesive, and (iii) screws. In another embodiment, the lower portion 1104 is adapted to releasably connect to the biopsy barcode reader by at least one of (i) snap-fits Gi) double-sided adhesive, and (ii) screws. Additionally, the lower portion 1104 may be adjustable such that the illumination adapter 1100 may be moved horizontally (i.e., forward, backward, and/or laterally), moved vertically, tilted, rotated, and/or otherwise shifted relative to the barcode reader 1122.
In other embodiments, the lighting adapter 1100 includes a top portion 1110 located above the one or more lighting components. The upper portion 1110 is adapted to releasably connect to at least one of (1) a monitor (not shown) above the biopsy bar code reader 1122 or (ii) a bracket (not shown) above the biopsy bar code reader 1122. In addition, the one or more illumination components positioned such that the effective range 1124 is both (i) unobscured by an upper flange 1126 of the biopsy bar code reader 1122 and (ii) illuminates at least a majority of a weighing platform 1128 of the biopsy bar code reader 1122.
In these embodiments, the upper portion 1110 is further connected substantially perpendicularly to the first surface 1102. Further, in these embodiments, the upper portion 1110 is adapted to releasably connect to at least one of (1) a monitor (not shown) above the biopsy bar code reader. 1122 or (ii) a bracket (not shown) above the biopsy bar code reader 1122 having at least one of © snap connections, (Gi) double-sided adhesive, and (ii) screws.
Additionally, the top portion 1110 may be adjustable such that the illumination adapter 1100 may be moved horizontally (i.e., forward, backward, and/or laterally), moved vertically, tilted, rotated, and/or otherwise shifted relative to the barcode reader 1122.
In certain embodiments, the first surface 1102 is further formed to include one or more cavities 1106 to receive the one or more lighting components and the lower portion 1104 is connected substantially perpendicular to the first surface 1102. The one or more cavities 1106 form permits the inclusion of the one or more lighting components and provides openings for the one or more lighting components to illuminate the weighing platform 1128 over the effective range 1124 . For example, the one or more cavities 1106 may be spaced as far to the right and left as possible. This maximum distance across the first surface 1102 further improves the imaging effectiveness of the biopsy bar code reader 1122 by reducing specular reflections from objects being processed.
Advantageously and as illustrated in FIG. 11B, the effective range 1124 includes the entire FOV 1130 of a color camera. Thus, and as discussed herein, the one or more cavities 1106 allow the one or more illumination components to fully illuminate all objects passing through the color camera FOV 1130 without distorting or otherwise adversely affecting the resulting color camera images. These advantages allow the combined system 1120 to capture more representative images than traditional systems, further allowing the combined system 1120 to more effectively perform machine learning (e.g., convolutional neural network) for faster, more reliable object identification.
In other embodiments, the first surface 1102 extends vertically up to 7 inches from the weighing platform 1128 of the biopsy bar code reader 1122. For example, and as illustrated by the profile view 1140 in FIG. 11C, the illumination adapter 1100 is positioned over the biopsy bar code reader 1122 such that the effective range 1124 is not obscured by the upper flange 1126 of the biopsy bar code reader 1100. If the first surface 1102 extends vertically up to 7 inches from the weighing platform 1128, fit the illumination adapter into the existing space between the biopsy bar code reader 1100 and other ancillary equipment while still providing illumination defined by an effective range 1124 which is both (i) unobscured by an upper flange 1126 of the biopsy bar code reader 1122 and (1 ) illuminates at least a majority of a weighing platform 1128 of the biopsy bar code reader 1122.
In certain embodiments, the lighting adapter 1100 further includes one or more baffles 1108 coupled to the first surface 1102.
The one or more baffles 1108 are configured to block at least an upper portion of the effective range 1124 of the one or more lighting components. The one or more baffles 1108 thus minimize eye irritation to the user of the biopsy bar code reader because the effective range 1124 of the one or more illumination components will not extend high enough to enter the user's FOV. In addition, the one or more baffles 1109 may be adaptable or interchangeable to further adjust the effective range 1124.
In other embodiments, and as illustrated in the combined system 1200 of FIG. 12A, the lighting adapter 100 includes an image processing assembly 1202 including one or more image processors configured to capture one or more images of one or more target objects. The first surface 1102 is further formed to include one or more secondary cavities 1204 to receive at least a portion of the image processing assembly 1202 . The image processing assembly 12 also has an effective range 1206, which may extend beyond the effective range 1124 of the one or more illumination components and/or the color camera FOV 1130.
