    Device for optical detection of objects
    The invention relates to a device for the optical detection of the lateral surface of elongate objects such as cables, ropes, tapes, rods and the like by an image capture device, wherein radiated from the object and / or reflected light is passed through beam paths of a reflection optics in the detection range of the image capture device.
    Devices for optical detection of the lateral surface of elongate objects such as cables, ropes, tapes, rods and the like have been known for some time and published in different embodiments.
    For example, devices for monitoring cable printing are known. In particular, for quality control, it is important that cable imprints are continuously monitored to detect possible errors early. For this purpose, devices are used which are arranged downstream of the printing machine and monitor the outer surface of the object, in this case the cable, via an optical image acquisition device. Since cables can be printed all around along their entire cylindrical surface, it is necessary to monitor the entire lateral surface. One possibility of the 360 ° all-round monitoring is the provision of several image capture devices, which can be designed, for example, as video recording devices, in particular video cameras. A disadvantage of this design is that the usually very thin cables fill only a small area of the possible image capture area of a camera. In order to be able to monitor the entire lateral surface of the object with sufficient quality, at least three, preferably four, radially arranged viewing directions are necessary. For the embodiment with several cameras, therefore, three to four cameras are necessary to monitor the entire lateral surface or a subregion of the lateral surface.
    A more convenient solution for 360 ° monitoring of elongated objects with a single image capture device is the provision of mirror optics. In this case, the front side, ie the side facing the camera, is taken directly by the image capture device. The back, that of the camera »· ·
    2 50 233 GP / GA facing away, is reflected by mirrors in the field of view of the camera. A disadvantage of this configuration is that the recorded images are present in different mirror orientations. Thus, the front of the object is not mirrored, and the back of the object is recorded mirrored. In particular, when using character recognition algorithms, pattern recognition algorithms or error detection algorithms, this mirroring is associated with additional expense. Another disadvantage is that a single image capture device also has only one Entfemungsbereich in which the object can be sharply recorded. Since the deflected beam paths of the images of the rear side of the object take a further path than the beam paths of the direct recording of the front side, there are problems with the focusing of the images.
    The object of the present invention is now to provide a device for optically detecting the lateral surface of elongated objects such as elongated cylindrical objects, cables, ropes, tapes, rods and the like, which overcomes the disadvantages of the prior art, while being inexpensive to manufacture , is easy, reliable and error-free in the application and also flexible to different application areas such as object diameter, etc. is customizable.
    The object according to the invention is achieved in that the number of reflections per beam path in all beam paths is either an even number or an odd number in all beam paths and that the average length of all beam paths is substantially equal.
    Further features according to the invention are that the reflection optics comprises reflection elements, via which images of parts of the lateral surface are directed into the detection area of the image acquisition device, that the images are guided via beam paths into the detection area of the image acquisition device, that at least three, preferably four, beam paths are provided and / or that the entire circumference of a partial area of the lateral surface of the object is detected by the image capture device via the images.
    In addition, the invention is characterized in that the optical detection of the lateral surface continuously by relative movement of the object along its • · · · · ft ftft ftft ft ft ft '* * · · · ···· ftft 1 ft ft ft ft ft * * * * ft ft ft ft ♦ ··· ft *

    Further features according to the invention are that the visual rays reaching the image capture device essentially follow the optical paths and that the visual rays are directed via the reflection optical system to a subregion of the lateral surface of the object, that the visual rays are directed to a subregion of the lateral surface of the object and preferably are distributed uniformly around the main extension axis of the object that an evaluation device for evaluating the guided into the detection range of the image capture device images of the object is provided that the images are passed as a digital signal of the image capture device to the evaluation device ind / or that the digital signal by evaluation algorithms such For example, text recognition, error detection, symbol recognition and / or pattern recognition can be evaluated.
    Furthermore, it is a part of the invention that the average length of the beam paths is substantially equal to the object distance of the image capture device, that the reflection optics as images of the lateral surface of the object continuously and in multiple beam paths in the receiving area of the image capture device conductive mirror optics and / or prism optics is executed in that a first beam splitter and a second beam splitter are provided in the detection range of the image capture device, that the second beam splitter is farther from the image capture device than the first beam splitter and / or that in the second beam splitter is wider than the first beam splitter and projects laterally beyond it.
    Features of the invention are also that the images of the lateral surface are consecutively guided side by side in the detection range of the image capture device that at least one light source is provided for illuminating the lateral surface of the object that the light source is controllable that the illumination duration of

    In a further consequence, the invention will be described in greater detail on the basis of concrete exemplary embodiments and illustrations.
    Fig. 1 shows a schematic representation of a possible embodiment of the device according to the invention.
    Fig. 2 shows a further embodiment of the device according to the invention in a schematic representation.
    Fig. 3 shows a similar embodiment of the device.
    1 shows a schematic representation of a device according to the invention for the optical detection of the lateral surface 1 of an object 2 by an image capture device 3. The main extension direction of the object 2 is projecting in the present view - ie, that the main extension axis of the cylindrical object is substantially normal to the representation plane , The image capture device 3 has a capture area 6 in which image capture can take place. The detection area 6 is that area which lies between the two lines which are also marked with the reference number 6 in the present illustrations. In essence, the coverage area corresponds to the area of coverage of a CCD chip that is variable depending on the focal length of an upstream lens or the acquisition sensor size (e.g., 1/3 ", V2", 2/3 ", etc.). For optical detection of multiple views of the lateral surface 1 of the object 2, a reflection optics 5 is provided. In the present embodiment, this comprises reflection elements 7 via which light emitted to the periphery of the object 2 and into the detection area 6 of the object area ··· * »· · · · ·« * * t * < »· · ··· ··· · * · • * · ¥ * · · t kBt *« ···· * · · ·

    Image capture device 3 headed wind. Through the reflection elements 7 of the reflection optics 5 beam paths are defined, along which the light is directed to the image capture device 3. It should be noted that the illustrated beam paths are schematic representations. About the reflection optics 5, it is also possible to direct parts of the lateral surface 1 of the object 2 in the Eifassungsbereich 6 of the image capture device 3, the direct recording would not be possible. As shown in FIG. 1, the rear side, that is to say the side of the object 2 facing away from the biosensing device 3, is also detected. For this purpose, the visual beams of the image capture device, which correspond to the reversal of the emitted light of the object, are guided via reflection elements 7 to the rear side of the object 2. In the present embodiment, four optical paths 4 are formed by the reflection optics 5. The first beam path 8 is directed, via one side of the second beam splitter 13, to the right front side of the object viewed from the image detection device. The second beam path 9 is guided on one side of the first beam splitter 12 and further reflection elements 7 on the right rear side of the object. The third beam path is directed via the first beam splitter 12 and further reflection elements 7 on the left rear side of the object 2 and the fourth beam path 11 is directed via the second beam splitter 13 and further reflection elements on the left front of the object. In addition, the beam paths 4 or at least the central rays of the beam paths strike the object 2 in a substantially radial manner uniformly distributed on the circumference of the object 2 and are uniformly distributed on the circumference, so that the individual beam paths about 90 °, preferably exactly 90 °, are arranged rotated to each other. By this configuration, four different images of the lateral surface 1 are directed from different directions into the detection area 6 of the image capturing device 3. Furthermore, the beam paths strike the object essentially in one plane. The arrangement makes it possible for the entire circumference of a partial area of the object 2 to be observed by a single image capture device 3. Is this shown in Fig. 1 with an image display device 14 which side by side the first view 15, the second view 16, the third view 17 and the fourth view 18 indicates the first view corresponds to 15 the view of the first beam path 8, the second «t ·· φ • φ« ♦ ·
    6 50 233 GP / GA
    View 16 of the view of the second beam path 9, the third view 17 of the view of the third beam path 10 and the fourth view 18 of the view of the fourth beam path 11. In a preferred manner, the individual images, so the views 15,16,17,18 konsekutiv , So consecutively directed into the detection range of the image processing device. That is, the images of a desired order are detected side by side by the image processing device. In the present embodiment, the desired order corresponds to the sequence of images in a rotational direction about the main axis of extension of the object. For example, this is the sequence of images from left to right of the object's views from the left front, followed by a left rear view, followed by a right rear view, followed by a right front view. By merging the individual images can be dargestelit beyond a settlement of the lateral surface.
    Conventional image capture devices are equipped with optics for focusing the object to be recorded, with the same object width or the same focal length range being valid for the entire detection range. In order to be able to focus on and / or display all views 15, 16, 17, 18 in the course of splitting the detection area 6 into a plurality of beam paths 4, it is necessary for the mean lengths of all beam paths 8, 9, 10, 11 to be substantially equal are and corresponds substantially to the object distance of the optics of the image capture devices, wherein in principle the focal length and the object width are decisive factors for the focusing. In addition, all views in the same mirror orientation, i. In addition, to represent either normal or mirror image, it is necessary for all the ray paths to pass through either an even number of reflections or all the ray paths through an odd number of reflections.
    The presence of equal gel orientation is particularly important if special evaluation algorithms such as, for example, character recognition, pattern recognition, etc. are used. For this purpose, an evaluation device 19 is provided. This is embodied, for example, as a data processing device and comprises program logics for analyzing the recorded images, in particular the images 15, 16, 17, 18. ♦ * * Ι * I ·· * · ♦ ·· * * · · · · · · · · · · · · * * * · ···· > · * · «Μ * · ♦ ··· · I 4 ·· Ψ · ·« ·· * · #

    In the present configuration, each beam path is mirrored three times. As a result, the images of the lateral surface 1 are always mirror-inverted detected by the image capture device. As a result of the evaluation device 19, the entire image can subsequently be mirrored via data processing algorithms, so that mirrored views prevail. However, this reflection of the entire recorded image only makes sense if all the images 15,16,17,18 in mirror-inverted orientation voriiegen.
    Due to the limitation of the detection range of the image capture device in the direction of the longitudinal extent of the object 2, only a portion of the lateral surface can be picked up by the image capture device when the object 2 is stationary. In particular, in the monitoring of elongated objects such as endless products, cables, tapes, ropes, etc., therefore, the object itself must be moved to detect a larger area or the entire shell. For example, in Kabelbedruckungsmaschinen the object 2 runs at a substantially constant speed through the printing machine. Subordinate, the device according to the invention is through which the object is also passed at a substantially constant speed. If, moreover, the image capture device is designed as a video camera or as a camera, which can record a chronological sequence of images, a continuous detection of subregions of the lateral surface is provided. In a preferred manner, a cylindrical section of the jacket of the object is received for each individual recording image. In addition, by selecting the image recording frequency or by selecting the frequency of external exposure sources, a standing, easy-to-analyze image can be generated by a stroboscopic effect. Thus, to generate the desired image, the recording frequency, that is, the number of images per unit of time that receives the image capture device; the shutter speed, ie the recording time of the individual pictures; the illumination duration of an external light source; the intensity of an external light source; the flash interval and / or the flash frequency of an external light source may be varied and / or synchronized. For example, the parameters mentioned are synchronized with each other and / or the parameters with the relative speed between the object and the device. As an external light source, to illuminate the male portion of the lateral surface of the object to provide continuous light body, but also
    8 50 233 GP / GA
    Flashlight-generating filament such as LED flashes on. These are arranged so that they are suitable for illuminating the desired portion. It can be provided as well as a single light source. The light of the light sources can be direct, filtered, passed over beam paths, reflection elements and / or the beam paths of the reflection optics on the object. For example, the light source can be arranged annularly, in sections or at points in the region of the opening for the passage of the object. Furthermore, the light source can also be provided in the region of the image recording device, in which case the light is conducted via the beam paths to the object. In order to produce a high-quality still image, the exposure times must be kept low, especially at high relative speeds between the object and the image capture device in order to avoid a blurring effect. The short exposure times also require sufficient illumination for a sufficiently exposed image. The higher the relative speed, the shorter the record must be and the more intense the lighting. The lower the production speed, the longer the shutter of the camera can remain open and the amount of light does not have to be so large as the CCD chip works accumulatively or cumulatively.
    However, it also corresponds to the idea of the invention to apply the analysis algorithms also to moving images.
    The reflection elements are preferably designed as a mirror. But they can be replaced by equivalent means, which allow to vary the direction, the course and the length of beam paths. Examples of further reflection elements are prisms, pentaprisms, light guides, etc. In addition, other optical elements such as lenses, optical elements for refraction, filters and the like can be used to improve the quality.
    Furthermore, to protect the device according to the invention, in particular against the contamination of the reflection optics 5, one or more viewing windows 22 may be provided. The object 2, which is guided through the opening 21 in the device, is spatially separated by the arrangement of the viewing window 22 of the mirror optics. Although the visual rays or the light can penetrate the viewing windows 22, the exchange of air, but in particular impurities such as dust, particles, liquids, »· ·· v * # 4» · · * »* φ • * * · # · φ *
    50 233 GP / GA 9
    Humidity, etc. is prevented. In a preferred way, the device comprises a closed space in which the reflection optics 5 are provided, and which is sealed against environmental influences.
    Fig. 2 shows a further possibility of the configuration of beam paths. In this case, four beam paths 4 are again directed via reflection elements 7 on the lateral surface 1 of the object 2. In turn, the reflection optics 5 comprises a first beam splitter 12 and a second beam splitter 13, the beam splitters 12, 13 being arranged substantially in the direct field of vision of the image capture device 3. As in FIG. 1, the first view 15 is through the first beam path 8, the second view 16 through the second beam path 9, the third view 17 through the third beam path 10 and the fourth View 18 passed through the fourth beam path 11 in the detection range of the image capture device.
    In the configuration according to FIG. 2, in contrast to FIG. 1, the numbers of reflections per beam path are not equal. The first and the fourth beam paths are each mirrored twice. The second and the third beam paths are each mirrored four times. Since the number of reflections - that is, two and four - are each even numbers, again, all the figures are in the same mirror orientation. Also in the present configuration, the average lengths of the individual beam paths 4 of all beam paths are substantially the same length so that all the images can be focused with a focusing optics of the image capture device.
    The second beam path 9 is shown schematically in Fig. 2 as a wider beam. The beam, which is preferably wider than the diameter of the object 2, is deflected by the reflection elements 7 of the reflection optics 5 and extends from a portion of the lateral surface 1 to the detection area 6 of the image capture device 3. The oblique impingement of the beam on the reflective elements, the Path lengths of two individual beams of the beam deviate from each other. Over the entire course of the beam path are the differences in length of individual beams of a beam ** ·· »· * ·· * * * * ··· * 4 ·»

    10 50233 GP / GA, however, are so small that they correspond to an object width range that can be recorded by the image capture device 3 as sufficiently sharp.
    FIG. 3 shows a configuration similar to FIG. 2 with four beam paths 4, in particular a first beam path 8, a second beam path 9, a third beam path 10 and a fourth beam path 11. In the course of the second beam path 9 and the third beam path 10 are taking place , as shown in Fig. 2, two reflection elements each provided a pentaprism 20.
    Also in this embodiment, radiated and / or reflected light of the lateral surface 1 of the object 2 is guided via beam paths 4 into the detection area 6 of the image capture device 3. For continuous detection of larger parts of the lateral surface, the object 2 along its longitudinal extension direction, in the present representation, that is normal to the image plane, arranged to be movable.
    As an alternative to the stationary device with a moving object, the device itself can also be used on a mobile basis in order to be able to inspect stationary objects. For example, it is necessary to carry out regular checks on existing objects such as suspended cables or ropeways of cable cars. For this purpose, the device according to the invention can be moved along the object, in particular along the main extension direction of the object, in order to detect the lateral surface.
    At this point it should be noted that the invention is not limited to the stated embodiments. Further embodiments corresponding to the concept of the invention also result from combinations of individual or several features which can be taken from the entire description, the figures and / or the claims. Thus, embodiments are disclosed that consist of combinations of features that come from different embodiments. The figures are at least partially schematic representations, wherein the dimensions and proportions of other, not graphically illustrated, embodiments or features as well as real versions may differ.
    It should also be noted that the beam paths of Figures 1 to 3 are merely schematic representations of the beam paths. Thus, according to the invention, several images are directed into the detection area of the image capture device. These images correspond to regions or bundles of multiple rays. The division of the areas in the detection area is largely given by the arrangement of the two beam splitters 12 and 13. In addition, due to the simpler representation, the ratio of the average lengths of the individual beam paths is not necessarily the reality. According to the idea of the invention, all beam paths 8, 9, 10, 11 are essentially the same length. This means that the average distance from the relevant optical element of the image capture device to the lateral surface of the object - ie the object width - is substantially the same for all beam paths. Variations of the lengths are given by the fact that a certain object width range is acceptable for focusing the images. Furthermore, an adaptation to certain length variations can also be made via differently curved lenses. ** ·· «··» * «
