    METHOD FOR INCREASING THE SPEED OF INSPECTION, AUTONOMOUS OPERATING EQUIPMENT AND DETECTION OF BEHAVIORAL FAILURES TO IMAGE SYSTEMS BASED ON MILLIMETRIC WAVES AND DEVICE FOR PUTTING IN SAID METHOD
    DESCRIPTION OBJECT OF THE INVENTION
    The present invention relates to a method that will increase inspection speed, provide autonomy and additional detection capabilities to image systems based on millimeter waves, those used for example to control safety in public places and / or media of collective transport. With this method you can obtain 360 ° images (full body scan) from a single image, which increases the inspection speed. In the same way, through volumetric sensors that detect and analyze the presence and position of people, the system will be given complete autonomy and an ability to detect abnormal behaviors. The invention also relates to the device that allows 360 ° scanning from a single view.
    BACKGROUND OF THE INVENTION
    Security in public places and / or in means of collective transport increasingly requires more sophisticated means of detecting threats, to counteract the increasing ingenuity of individuals who intend to create danger or damage.
    As a paradigmatic example of the above, it is worth mentioning the increasingly sophisticated means of reviewing passengers at airports, which given the situation become essential.
    The current means include laser scanners of luggage and personal items, metal detection arches carried by passengers, portable metal detectors, and a whole ritual of stripping shoes, watches and other items that are part of life Daily control of an airport. These means of control have the disadvantage that they greatly slow down people's traffic through controls and,
    5
    10
    fifteen
    twenty
    25
    30
    35
    especially that they do not have total effectiveness, since it is not possible to individually cache each person, and there are objects that can result in a threat that are not capable of being detected by the exposed means.
    A substantial improvement of the previous situation consists in the utilization of body scanners. These devices comprise a scanning element that is capable of inspecting the subject that passes through the control without physical contact, and they are based on the detection of energy waves coming from the subject and computer processing thereof, so that through software it is possible to Compose an image. Since the energy coming from the subject varies according to whether it comes from its anatomy or from objects carried by it, the images composed by the software will show the objects that it can carry, and therefore any weapon or object carried by the subject will be detected, although Do not be metallic.
    These scanners can be active or passive. Active scanners radiate the subject to pick up reflected waves (radar) or even through it (X-rays) and have the disadvantage that they precisely radiate the subject, even with ionizing radiation. For this reason, passive scanners, which are usually based on the detection of millimeter and / or sub-millimeter waves naturally radiated by bodies and / or objects by at least one millimeter wave camera, are preferable.
    The use of body scanners is so advantageous that it has already been implemented in certain airports, and certain countries are considering mandatory implantation in all their airports.
    Despite the progress made in the use of body scanners, its use requires that the subject adopt a certain position in a fixed location, and remain immobile during the scan. As current regulations only allow people to be scanned in static mode, the subject must be scanned successively in various positions or positions that reflect their entire anatomy, which slows the flow of passengers or people through control. To solve this, detectors have been implemented, usually in cabins, which rotate and / or move around the body, but such implementation is very expensive and generates complications in the algorithms. In addition, the use of moving parts poses a danger of collision with the subject.
    Another additional drawback is that, during scanning, the subject must remain
    3
    5
    10
    fifteen

    25
    30
    completely immobile, and small movements can invalidate the scan and force to repeat it, circumstance that is not detected during the scan but at the end of it, with the loss of additional time, and that requires the attention of personnel to indicate to the subjects the position to adopt, that they are immobile etc, which can distract them from the main function that would be the detection of possible threats.
    All existing security systems described are tools that facilitate the work of security personnel, police and civil guard, automating operations that would otherwise require manual registration. However, the experience and the sixth sense that people have brings a value that to date has no security system. There are solutions that detect abnormal behaviors based on the analysis of video images, whether full-length, facial, but there are no algorithms that interpret body language in the same way as an experienced agent does.
    DESCRIPTION OF THE INVENTION
    The method of the invention enables high speeds of scanning at 360 degrees of a person, at least twice the current speeds, which is capable of increasing the flows of people by the control where they are implemented. The method is implemented with the device of the invention, which is also capable of understanding additional functionalities.
    According to the invention, the method comprises the following steps:
    -detection of placement of the subject in the fixed location by means of motion sensors,
    - comparison of the posture of the subject with the determined posture of scanning, and issuance of corrective orders of the posture in case of non-coincidence,
    -Once in position, I start with a scanning element of the energy reading in the form of millimeter and sub-millimeter waves coming directly from the front of the subject and reflected from a reflector on the back of the subject,
    -discrimination of direct and reflected waves according to the readings of the motion sensors,
    -Additional captation of the movements performed by the subject during scanning by
    5

    of motion sensors,
    - comparison of the movements captured by the motion sensors with maximum validity values, and restart of the scan in case of being overcome with notice to the subject so that he knows of the restart and so that he maintains the position and immobility,
    - Comparison of the movements captured by the motion sensors with movement patterns with a lack of naturalness stored in the first databases, and activation of additional actions in case of coincidence, such as closing of locks, alarm connection for warning to the security personnel etc,
    -composition of an image of the subject from the readings of the scanning element, -analysis of the composite image and comparison with forms of known threats (weapons, suspicious packages).
    -activation of additional actions in case of coincidence.
    The device of the invention serves to implement the method of the invention. It is of the type that comprises a scanning element by capturing energy waves in the form of millimeter and sub-millimeter waves coming from the subject, and that is located in a fixed location - the control point - where the scanned subject must maintain a certain position while method application lasts
    In accordance with the invention, the device comprises a wave reflector opposite the scanning element. Said reflector is formally and dimensionally suitable to reflect waves from the back of the subject towards the scanning element without changing the position of the subject, so that the scanning of the back and front of the subject can be carried out almost simultaneously, without the loss of time that It implies the change of position and the adoption of the proper posture again, and without the need to implement cabins with rotating scanners and doors, which have a much slower operation.
    In addition, the invention contemplates the implementation of the subject's movement sensors during their body scanning. These motion sensors discriminate the position of the person and the background, so that they cooperate in determining that part of the energy received in the scanning element proceeds directly. of the person and what part is reflected, this being a fundamental parameter for the subsequent computer treatment and composition of the corresponding image. It also has additional functionalities, so that if a movement of undue amplitude is detected during the scan, it will be restarted.
    same, and a sound or audiovisual instruction player will be activated, so that

    Automatically warn the subject of the position to be taken or that is not sufficiently immobile. This also saves downtimes consisting of the completion of a scan that would not be valid for containing inappropriate movements, as well as dedicating personnel to instruct the subject, personnel who can fully concentrate on the detection of threats.

    -Once in position, I start by means of a scanning element (2) (millimeter and sub-millimeter wave camera) of the energy reading in the form of millimeter and sub-millimeter waves (3) coming directly from the obverse of the subject (5), and reflected from a reflector (6) on the back of the subject (5),
    -discrimination of direct and reflected waves according to the readings of the motion sensors (9),
    -Additional capture of the movements made by the subject (5) during scanning by means of the motion sensors (9),
    - comparison of the movements captured by the motion sensors (9) with maximum validity values, and restart of the scan in case of being exceeded, with notice to the subject (5) so that he knows of the reset and so that he maintains the position and immobility, - comparison of the movements captured by the motion sensors (9) with movement patterns with a lack of naturalness stored in a first database, not represented, and activation of additional actions in case of coincidence, such as closing of locks, alarm connection, warning, etc,
    -composition of an image of the subject from the readings of the scanning element (2), -analysis of the composite image and comparison with forms of known threats (weapons, suspicious packages).
    -activation of additional actions (alarm, blocking of the locks (11)) in case of coincidence, which implies the detection of a threat.
    With the method of the invention the scanning speed is improved, since in the situation prior to the present invention, and shown in Figure 5, only the waves (3) coming from the obverse will arrive, so that the subject (5) should turn to scan your reverse.
    The stage of comparing the movements captured by the motion sensors (9) with the movement patterns with a lack of naturalness is carried out by means of 3D sensor systems existing on the market, such as the Kinect® system from Microsoft® or Primesense®, that are able to give information about the 3D movement of a body, estimate the mechanical movement of the subject based on the location of points that define a virtual skeleton (feet, knees, hips, wrists, elbows, shoulders, neck, head, etc. ), as well as a face quality image, preferably using several sensors simultaneously that will inspect the person from different angles to improve the
    total system resolution. Specifically, preferably said stage will comprise the

    following sub-stages:
    -Identify and classify by subject, sex and age group the subject (5) to be inspected, according to the images taken by the scanning element (2),
    -register their movements by means of the motion sensors (9),
    -Compare registered movements with models based on first databases of:
    i) movements corresponding to people with some type of mobility problem,
    ii) movements corresponding to threats,
    iii) movements corresponding to people with some type of problem that affects their mobility and threats, and
    -determine if there are matches, in which case the additional actions will be activated
    The initial position, final position, module and velocity vector and acceleration of the different points of the skeleton, and the variation of these parameters of each point of the skeleton between each other, will be measured in time in this way analyze the synchronization of movements of the whole body during the inspection process.
    Each first database will include information on people of different sex, age and fisionomla (distribution of body mass, height), who have undergone the inspection protocol, and more specifically the database for people with mobility problems will ideally include problems joint, bone, prosthesis, or any other problem that affects the biomechanical analysis.
    The stage of analysis of the composite image and comparison with forms of known threats can be carried out by means of ocular inspection on the screen (10), or also by automatic comparison of the composite image with patterns of dangerous objects stored in a second database. , not represented.
    If there are no coincidences with the first databases in the stage of comparing the movements captured by the motion sensors (9) with the movement patterns with a lack of naturalness, and in the subsequent stage of analysis of the composite image on the screen (10) and comparison with known threat forms the scanning element (2) (the millimeter wave camera) does not detect any threat, the inspection will be approved and
    It will allow the person to follow his path. If lack of naturalness is detected but at the stage of

    Image analysis no threat is detected, then subject (5) will be required to repeat the complete inspection and notification will be sent to security personnel. If once the second inspection is completed, the movement enters both the group of people with reduced mobility, the security personnel will be notified. Any other case will also be notified to security personnel.
    After the inspection carried out with the supervision of the security personnel, and that could include any type of sensor-based inspection method, or manual by the security personnel, the result will be inserted into the database through the interface of user, so that the databases grow and learn.
    The device (1) of the invention serves to obtain full-body millimeter images from a single view according to the method of the invention, and is of the type comprising a scanning element (2) by wave captation (3 ) of millimeter and sub-millimeter energies from a subject (5) located in a fixed location (4), in which the scanned subject (5) must maintain a certain position, and which according to the invention, also includes a reflector ( 6) of waves opposite the scanning element (2), formally and dimensionally suitable to reflect waves (3) coming from the back of the subject (5) to the scanning element (2) without changing the position of the subject (5) - as It is seen in Figure 6-, so that the front and back of the subject can be scanned almost simultaneously, and without changes in position. It also includes sensors (9) of three-dimensional movement of the subject (5) during their body scan, said movement sensors (9) being associated with the scanning element (2), so that through them a discrimination is made between the position of the subject (5) and the background, helping to distinguish direct waves from those reflected to compose the body image, which will be visible for example on a monitor (10). Likewise, the association between the motion sensors (9) and the scanning element (2) allows a new scan to be initiated in case of excessive movement detection. In addition, optionally, the motion sensors (9) may be associated with at least one sound or audiovisual player of instructions -that through the monitor (10) or speakers and / or another screen indicates to the subject (5) the position correct or the mistakes made-, to security locks (11) that block the subject (5), to a warning alarm (12), for example and / or to a database of threatening movements, which stores movement patterns threatening, for activation of additional actions in case of coincidence, such as closing of locks, alarm connection, etc.

    Said motion sensors (9) comprise in this example of the invention, at least, depth sensors that give depth information and generate a three-dimensional image, with the additional advantage that they can be associated with an image recorder (14) that can serve as evidence in certain processes derived from scanning.
    On the other hand, the scanning element (2) can be passive or active. In this example of non-limiting realization it is passive, and comprises a millimeter and sub-millimeter wave camera, understanding as such that it is capable of detecting spectra with wavelengths between 10GHz and 1000GHz. In addition, the scanning element (2) can be complemented by a multispectral or hyperspectral camera
    As for the reflector (6), it may comprise a concave reflective element, so that its emitting focus would be the reverse of the subject and the reflected beam will influence it on the scanning element (2); however, in this example of embodiment of the invention, the reflector (6) comprises a plurality of reflective elements (6a, 6b) with different orientations, which manage to reflect the waves (3) towards the scanning element, as seen in Figure 6
    It is envisaged that at least one of the different reflective elements (6a, 6b) is mounted on an adjustable support (7), which may even comprise means of dynamic orientation, not shown, that is, synchronized with the element scanning (2) so that during scanning they are able to vary their orientation at any time to reflect the waves (3) correctly towards said scanning element (2), whose software will properly interpret the waves (3) received to compose body image, which will be, for example, visible by means of a monitor (10). As for said means of dynamic orientation, any of those existing in the state of the art, such as servomotors and the like, will be valid.
    More specifically, the reflector (6) shown in this example of the invention comprises a dihedral of two reflective elements (6a, 6b), with regulation of its opening angle (15) (see fig. 3) between 151 and 180 degrees, while said reflective elements (6a, 6b) ideally have a fixed inclination angle (16) of 5 degrees (see fig. 4). In addition, it is provided that each of the two reflective elements (6a, 6b) has a height between 160 and 210 centimeters and a width between 85 and 110 centimeters, and more
    preferably a height of 170 centimeters and a width of 100 centimeters.

    As for the reflective elements (6a, 6b), they are preferably materialized in a mirrored glass mirror, or in reflective metal surfaces, as for example in the latter case in flat aluminum sheet.
    Describing sufficiently the nature of the invention, as well as the manner in which it is carried out in practice, it should be noted that the provisions indicated above and represented in the attached drawings are subject to modifications in detail as long as they do not alter the fundamental principle.
