Description

Technical Field

[0001] The present invention relates to a method for an operator separation device and an operator separation device having an automatic door system. Background Technology

[0002] Personnel separation devices are well known in the art, for example, in the entrance areas of buildings. Typically, personnel separation devices rely on separation structures (such as rotary gates or speed gates), which are installed in addition to doors to achieve the desired separation.

[0003] To date, systems that rely on doors for personnel separation are highly unreliable because if there are other people in front of the door, it is impossible to isolate a person.

[0004] Therefore, the object of the present invention is to provide a method for an operator separation device and an operator separation device that operates reliably and does not require a separation structure, but relies on a door to separate personnel. Summary of the Invention

[0005] To this end, a method for an operator separation device is provided, the method comprising a permission system having at least one permissioned area, a tracking unit, and at least one automatic door system. The automatic door system includes a door, at least one drive unit for actuating the door, a camera, and a control unit for controlling the drive unit, wherein the camera's field of view includes the permissioned area. The method includes the following steps:

[0006] - Capture video footage using a camera and transmit the footage to a tracking unit, wherein at least one person is present in the video footage.

[0007] - The tracking unit receives the results of the licensing process for at least one person in the licensing area from the licensing system.

[0008] -The tracking unit sets the permission status of the at least one person based on the result of the permission process for that person.

[0009] -The movement of at least one person in the video recording is tracked by the tracking unit after the authorization process, and

[0010] - Control the drive unit based on the movement and permission status of the at least one person.

[0011] By recording video of the permitted area, determining the permission status of individuals in the video, and tracking their movement from the permitted area to the door, the operation of individually controlled doors can be precisely controlled. Therefore, the door can be operated very reliably, ensuring that only those authorized to pass through the door can actually pass through.

[0012] In particular, these people are not hindered by doors; for example, they do not need to change their pace or direction.

[0013] The video recording includes, for example, at least a portion of the door's trajectory and / or at least one terminal and the area between the door.

[0014] Video recording can be a recording of a series of consecutive images and / or a video recording.

[0015] Specifically, the control drive unit is configured such that if its permission status indicates that the at least one person is permitted to pass through the door, then the door is opened for the at least one person.

[0016] Doors can be revolving doors, rotating doors, sliding doors, folding doors, etc.

[0017] For example, a camera is an integrated part of the door's security function, and it monitors, for example, the door's trajectory, especially the trajectory of the door leaf.

[0018] Specifically, the camera was mounted above the door.

[0019] The tracking unit can be part of the gate system, particularly part of the control unit, or the tracking unit can be separate from the gate system, for example, set up as a cloud server.

[0020] For example, the tracking unit identifies, tracks, and sets the permission status of multiple people appearing in the video recording, specifically each person in the video recording has a separate permission status, and tracks their movement individually.

[0021] The licensing system may include more than one terminal.

[0022] On the one hand, if the tracking unit has received a positive result from the person's permission process, and optionally, if at least one permission condition has been met, then the permission status of the corresponding person in the video is positive; and / or if the tracking unit has not received a positive result from the person's permission process, or optionally, if at least one permission condition has not been met, then the permission status of the corresponding person in the video is negative. In this way, precise permission status can be assigned.

[0023] In one embodiment, the authorization process includes detecting an authorization action performed by the at least one person within an authorization area, and evaluating the performed authorization action by an authorization system, wherein the outcome of the authorization process is positive if the authorization action meets at least one predetermined criterion. Based on the outcome of the authorization system, precise information is used to determine whether a person can pass through a door. The reliability of the method can be further improved by utilizing authorization conditions.

[0024] To provide good usability for personnel, the licensing system may include at least one terminal located in the licensing area, on which licensing actions are performed.

[0025] In one embodiment, the terminal is an authentication terminal and / or a payment device, wherein the authorization action is an authentication action and / or a payment action, wherein a predetermined criterion for the authorization action is met if the authorization action has resulted in successful authentication and / or authorization of the at least one person and / or if the payment has been successfully completed. In this way, the authentication and / or payment process can be processed automatically.

[0026] The terminal can also be a sanitary device, and the authorized action is to use the sanitary device.

[0027] In another aspect of the invention, the tracking unit receives information about at least one attribute of a person from a licensing system (particularly a terminal) and determines the same at least one attribute of the person in the video recording, wherein a licensing condition is satisfied if the at least one attribute received from the licensing system matches the determined at least one attribute. By checking the attributes of the person, the accuracy of the tracking system is improved.

[0028] The at least one attribute may be the age, gender, height, and / or body movement pattern of the relevant person.

[0029] For example, the drive unit is controlled to open the door for a specific person if that person approaches the door, their permission status is affirmative, and optionally, at least one safety condition is met; and / or to keep the door closed or control the drive unit to close the door if the person approaches the door but their permission status is negative and / or optionally, at least one safety condition is not met. This reliably controls personnel access to the area behind the door. Using safety conditions can further improve the reliability of personnel separation.

[0030] On one hand, the at least one security condition includes the integrity of the door-related security zone, which is a predetermined area in the video recording. The shape and / or size of the door-related security zone depends on the kinematic attributes of the unauthorized person, particularly their walking speed, direction of travel, and distance to the door. The security condition regarding the integrity of the door-related security zone is satisfied if no unauthorized person is present within the door-related security zone. This prevents individuals loitering in front of the door from entering the area behind it.

[0031] For example, a door-related security zone corresponds to the area in front of and / or adjacent to a door, particularly in front of an open passageway. For instance, if an unauthorized person is (partially) within a door-related security zone, the corresponding security requirement is not met.

[0032] In another aspect, the at least one security condition includes the integrity of a dynamic personal security zone around a specific person, which is an area with a predetermined or dynamic shape and size around the specific person in the video recording, wherein the security condition regarding the integrity of the dynamic security zone is met if there is no unauthorized person within the dynamic security zone. When using a dynamic security zone, an intruder may not be able to enter through a door by tailgating or carrying an authorized person.

[0033] Dynamic security zones specifically correspond to the areas surrounding specific individuals. For example, if an unauthorized person is (partially) within a door-related security zone, the corresponding security conditions are not met.

[0034] To reduce the number of situations where a door remains closed without a valid reason, the shape and / or size of the door-related security zone and / or the shape and / or size of the dynamic security zone can be selected such that the door can be safely closed between authorized personnel passing through the door and unauthorized personnel following behind them, and / or the size of the door-related security zone and / or the size of the dynamic security zone depends on the current width of the door's opening passage.

[0035] In one embodiment, the at least one security condition includes the permissibility of a specific person merging with a previously isolated object, particularly wherein merging with a previously isolated inanimate object is permissible. This allows inanimate objects to be considered and addressed in the decision to open the door. If merging does not occur, this security condition is also satisfied.

[0036] In this disclosure, fusion is the process of two objects and / or persons that were previously identifiable in a video recording approaching each other until they are no longer identifiable to each other, and which are treated as a single object or person by the camera and / or tracking unit due to the camera's specific perspective on the scene.

[0037] The objects to be isolated can be bags, briefcases, etc.

[0038] In another aspect of the invention, the at least one security condition includes the permissibility of merging between the designated person and another person, specifically wherein merging between an authorized person and another person is permitted only if the other person is also an authorized person. This prevents an intruder from entering through a door while hiding behind an authorized person. This security condition is also satisfied if merging does not occur.

[0039] In order to communicate with at least one person in front of the door, the door system and / or the building in which the door system is installed may include a signaling device, particularly an optical and / or acoustic signaling device, wherein the signaling device is activated by a tracking unit and / or a control unit if the permission status of the person is negative when the person attempts to pass through the door, and / or optionally, if at least one security condition is not met.

[0040] In one embodiment, the door includes at least one door leaf actuated by a drive unit, wherein when the drive unit is controlled to open the door, the door leaf is moved to open the door, thereby creating a passageway with a width such that only specific persons approaching the door can pass through the door, achieving reliable personnel separation.

[0041] To further increase the reliability of separation, the door may include at least two door leaves and two drive units for independently actuating the door leaves, wherein when the drive units are controlled to open the door, the drive units actuate the door leaves such that the door is opened directly in front of a specific person approaching the door at a position along the door passage, and in particular, wherein the door leaves can move beyond the middle of the door passage.

[0042] In another embodiment, at least one main door system and at least one secondary door system are provided, wherein the secondary door system and the terminal are disposed on opposite sides of the main door system, and the method further includes the following steps:

[0043] - The secondary door system's cameras capture video and transmit the video to the tracking unit, wherein at least one person present in the main door system's video is also present in the secondary door system's video, specifically after passing through the main door system's door.

[0044] -The movement of at least one person in the video recording of the secondary gate system is tracked by the tracking unit, and

[0045] - The drive unit of the secondary door system is controlled based on the movement of the at least one person and their permission status.

[0046] Specifically, the main gate system is associated with or includes a main tracking unit for tracking the at least one person in the video captured by the main gate system, and the secondary gate system is associated with or includes a secondary tracking unit for tracking the at least one person in the video captured by the secondary gate system, wherein the main tracking unit sends the permission status of the at least one person to the secondary tracking unit.

[0047] By providing a secondary door system, the possibility of intruders entering is virtually eliminated, as intruders would have to pass through both the main door system and the secondary door system.

[0048] For example, the field of view of a camera in a secondary door system does not include the terminal, and may not include the door of the primary door system.

[0049] To allow for tree-like access structures and / or complex access schemes to different parts of a building, at least two secondary door systems can be provided, with doors in the secondary systems accessible directly from the main door system. Specifically, the permission status of said at least one person also depends on the particular secondary door system. In particular, the permission status of a person may differ for different door systems.

[0050] In this disclosure, direct access means that a person can reach the main door system without having to pass through the doors of another secondary door system.

[0051] For real-time and reliable determination and evaluation, tracking of at least one person in the video recording, determination of the attributes of the person in the video recording, determination of whether at least one attribute of the input data matches the at least one determined attribute, determination of whether and / or which security condition is met and not met, determination of whether a door should be opened, how wide it should be opened and / or where it should be opened, can be performed by deterministic algorithms of the tracking unit, machine learning algorithms, support vector machines and / or trained artificial neural networks.

[0052] Specifically, the artificial neural network is trained using training data, wherein, for various training scenarios, the training data includes input data of the same type and structure as the data fed to the artificial neural network during normal operation of the personnel separation device, and information about the expected correct output of the artificial neural network for the training scenario; the training includes the following training steps:

[0053] - Feeding input data forward via an artificial neural network;

[0054] - The response output is determined by an artificial neural network based on the input data.

[0055] - Determine the error between the response output of the artificial neural network and the expected correct output of the artificial neural network; and

[0056] - The weights of an artificial neural network can be changed by backpropagating the error.

[0057] Specifically, the input data includes video footage generated by a camera, at least one attribute of a person in the video footage, and / or the result of a permission process; wherein information regarding the expected correct output includes the actual movement of the person in the video footage, the actual attributes of the person in the video footage, a determination of whether the at least one attribute of the input data matches the at least one determined attribute, a determination of whether and / or which security condition is met and / or not met, and / or a determination of whether a door should be opened, when it should be opened, how wide it should be opened, and / or where it should be opened; and wherein the response output includes the determined movement of the person in the video footage, the determined attributes of the person in the video footage, a determination of whether the at least one attribute of the input data matches the at least one determined attribute, a determination of whether and / or which security condition is met and / or not met, and / or a determination of whether a door should be opened, when it should be opened, how wide it should be opened, and / or where it should be opened.

[0058] The video recording of the input data can be generated by a camera, which means that the video recording can also be generated using cameras of the same type of automatic door system (such as the Dominion system) and / or cameras in the laboratory with the same or equivalent field of view.

[0059] For example, the result of the licensing process is transmitted to the tracking unit via a wireless connection, a wired connection, and / or using a light source from the terminal, the light source being included in the video recording, and the result is obtained by the tracking unit from the video recording, thereby ensuring that the result of the licensing process is reliably transmitted to the tracking unit.

[0060] To achieve the above objectives, a personnel separation device is also provided, comprising a permission system having at least one permission area, a tracking unit, and at least one automatic door system. The automatic door system includes a door, at least one drive unit for actuating the door, a camera, and a control unit for controlling the drive unit, wherein the camera's field of view includes the permission area. The personnel separation device is configured to perform the method described above, specifically, wherein the tracking unit is part of the door system, for example, part of the control unit.

[0061] The characteristics and advantages discussed regarding this method also apply to this personnel separation device, and vice versa.

[0062] The licensing system may include terminals located in the licensed area.

[0063] The permission system is configured to determine whether specific personnel are allowed access to the area behind the automatic door.

[0064] In one embodiment, the personnel separation device includes at least one main door system and at least one secondary door system. In particular, the main door system is associated with or includes a main tracking unit for tracking the at least one person in the video captured by the main door system, and the secondary door system is associated with or includes a secondary tracking unit for tracking the at least one person in the video captured by the secondary door system.

[0076] Figure 11 A personnel separation device according to a third embodiment of the present invention is illustrated schematically. Detailed Implementation

[0077] Figure 1 The personnel separation device 10, which includes a permission system 12, a tracking unit 14, and an automatic door system 16, is shown schematically in a top view.

[0078] Automatic door system 16 Figure 2 The diagram shows this in more detail. The automatic door system 16 has a door 18, which in the illustrated embodiment is a sliding door with two door panels 20, a control unit 22, two drive units 24, and a camera 26.

[0079] Door 18 can also be a revolving door, a rotating door, a folding door, etc. The operating method remains unchanged.

[0080] The camera 26 and the drive unit 24 are connected to the control unit 22, wherein the control unit 22 is configured to control the drive unit 24.

[0081] Each drive unit 24 is associated with a door leaf 20 and is designed to move the corresponding door leaf 20 along a trajectory. The door leaves 20 can move independently of each other.

[0082] Specifically, the door 20 is movable, allowing a passageway between the door 20 to be opened, wherein the width W of the passageway can be adjusted by the control unit 22.

[0083] The camera 26 has a controller 27 and is located above the door 18, that is, above the track of the door leaf 20.

[0084] Camera 26 is an integrated part of the safety functions of the door system 16. Specifically, camera 26 monitors the trajectory of door 18, i.e., the movement path of door leaf 20, and forwards this information to control unit 22 or its integrated controller 27. Based on this information, integrated controller 27 and / or control unit 22 control drive unit 24 to ensure the safe operation of door 18. Specifically, this is to prevent people (especially children) present in the trajectory of door 18 from being injured by door leaf 20.

[0085] The tracking unit 14 can also be part of the automatic door system 16. For example, the tracking unit 14 can be integrated into the control unit 22 or into the controller 27 of the camera 26. The tracking unit 14, as part of the camera 26, Figure 2 The middle part is represented by a dashed line.

[0086] Alternatively, it is conceivable that the tracking unit 14 is separated from the gate system 16. In this case, the tracking unit 14 can be provided as a server (in... Figure 1 (shown as dashed lines), such as cloud servers or local servers.

[0087] In any case, the tracking unit 14 is connected to the licensing system 12 and the control unit 22 and / or the drive unit 24.

[0088] Back Figure 1 The licensing system 12 includes a licensing area 28, an evaluation unit 30, and a terminal 32 in the illustrated embodiment.

[0089] Permission zone 28 is an area in front of door 18 where a person wishing to pass through the door must perform a permission action.

[0090] Terminal 32 is located within licensed area 28. This includes situations where personnel within licensed area 28 can interact with terminal 32 from outside the licensed area.

[0091] In the illustrated embodiment, terminal 32 is depicted as an authentication terminal or payment device.

[0092] When the authentication terminal is used as terminal 32, the personnel separation device 10 can be located in the entrance area of ​​the building to control personnel access to the restricted areas of the building for authorized personnel.

[0093] In the case where a payment device is used as terminal 32, the personnel separation device 10 can be located at the exit of a supermarket or retail store to ensure that only those who have paid can leave the store.

[0094] Terminal 32 can also be a sanitation device, such as a disinfectant dispenser, sink, or purification device. In these cases, personnel separation device 10 can restrict entry into and / or exit from areas with specific sanitation standards, such as hospital wards, laboratories, and clean rooms.

[0095] Terminal 32 may also be a detection device, such as for detecting radioactivity or sunscreen for detection applications, or an interactive device with a display, such as a display for automatically replaying video with safety instructions. Separation device 10 may only be allowed entry if the measurement value of the detection device is normal (e.g., above or below a predetermined threshold) or if interaction with the display has been successfully performed (e.g., the instruction video has been watched until its end).

[0096] Terminal 32 is connected to evaluation unit 30, and evaluation unit 30 receives input from terminal 32.

[0097] The evaluation unit 30 can access the database 34 via a network connection to a server on a local network or the Internet, or because the database 34 is part of the evaluation unit 30.

[0098] The evaluation unit 30 is then connected to the tracking unit 14. This connection can be wired or wireless.

[0099] Figure 3 a to f in the figures illustrate a method of operating the personnel separation device 10 according to the invention, wherein the personnel separation device 10 is shown at different time points during the method. Figure 4 A flowchart of the method according to the present invention is shown.

[0100] Figure 3 The 'a' in the text corresponds to Figure 2 No one approached door 18.

[0101] However, in step S1, camera 26 captures video including the field of view F of camera 26.

[0102] Figure 2 and Figure 3 The field of view F is shown in dashed lines in section a. The field of view F includes the permitted area 28, which in turn includes the terminal 32 (if present), and the trajectory of the door 18, and in particular the trajectory of the door leaf 20.

[0103] Therefore, the area between terminal 32 and / or licensed area 28 and door 18 is also included in the video recording.

[0104] The field of view of camera 26 can cover an area measured on the ground, up to 5 meters, preferably 7 meters, and more preferably 10 meters in front of door 18.

[0105] Video recordings are, for example, recordings of a series of consecutive images and / or video recordings.

[0106] exist Figure 3 In section b, it is desired that person P enters the field of vision F and the permitted area 28 through door 18. Therefore, person P is captured in the video recording.

[0107] The video recording is sent (particularly continuously) to the tracking unit 14, and the tracking unit determines in step S2 that a person is present in the video recording, more precisely, that a person is present in the permitted area 28. From this point on, the tracking unit 14 tracks the movement of the person P over time.

[0108] Personnel P performs a licensing action in licensed area 28. In the illustrated embodiment, the licensing action involves interaction with terminal 32.

[0109] When the authentication terminal is used as terminal 32, personnel P can present his / her identification card to terminal 32, which will then read it and / or interact with the biometric sensor 33 of terminal 32 (e.g., fingerprint sensor, iris scanner, etc.).

[0110] When a payment device is used as terminal 32, person P can perform a payment as an authorization action on terminal 32.

[0111] When a sanitary device is used as terminal 32, the correct use of the sanitary device is a permitted action.

[0112] The licensing action may also not involve interaction with terminal 32, for example, if a payment is made through a personal mobile device.

[0113] In any case, in step S3, the evaluation unit 30 performs the authorization process. To this end, the evaluation unit 30 evaluates the authorization action and determines, based on the authorization action, whether the authorization action meets the predetermined criteria for indicating whether the corresponding person P is allowed to pass through the door 18.

[0114] For example, assessment unit 30 determines whether person P is authorized to pass through the area behind door 18 based on data received from the identification card and information based on database 34.

[0115] Similarly, the assessment unit 30 can verify the payment and whether the payment reaches the amount required to leave through the door 18, such as the value of goods purchased in the store.

[0116] If the assessment by assessment unit 30 has been successful, for example, if the certification and authorization of personnel P are affirmative or the necessary amount has been paid in full, then the assessment unit determines that the licensing process is affirmative.

[0117] In step S4, the result of the licensing process is sent to the tracking unit 14.

[0118] The transmission of the results of the licensing process can be performed through the connection between the evaluation unit 30 and the tracking unit 14 as described above.

[0119] The connection between the licensing system 12 and the tracking unit 14 can also be optical. In this case, the terminal 32 includes a light source 35 located within the field of view F of the camera 26 and illuminated to indicate the result of the licensing process.

[0120] The tracking unit 14 can also receive other attributes of the person P from the authorization system 12 (specifically, terminal 32 or evaluation unit 30). These attributes can be stored in a database 34 accessed by the evaluation unit 30 and / or included on the identification tag.

[0121] The attributes of person P can be person P's age, gender, height, and / or body movement pattern.

[0122] In step S5, the tracking unit 14 associates the identified person P in the video with the result of the authorization process received from the evaluation unit 30.

[0123] Based on the result of the licensing process, the tracking unit 14 sets the licensing status of personnel P accordingly. Since personnel P has just performed a licensing action in the licensing area 28, the tracking unit 14 can easily identify the person corresponding to the result of the licensing process.

[0124] Alternatively or additionally, the tracking unit 14 may determine the same attribute of the person P in the video recording as the attribute received from the licensing system 12.

[0125] Then, in step S5.1, the tracking unit 14 can compare the attributes of the person P obtained from the video recording with the attributes received from the licensing system 12.

[0126] This comparison can be used to improve the accuracy of the association between the person P in the video recording and the licensing results received from the licensing system 12.

[0127] It can also be used, or alternatively, for further authentication of person P, such as verifying whether the ID card presented to terminal 32 belongs to person P in the video recording. This verification is referred to below as an authorization condition.

[0128] If the attributes received from the licensing system 12 match the attributes determined from the recording, the licensing conditions are met.

[0129] If the licensing conditions are met and a positive result is obtained from the licensing process, the tracking unit 14 sets the licensing status of the corresponding person P to a positive value.

[0130] If the permission conditions are not met, i.e., the attributes of person P received from the permission system 12 do not match the attributes of person P determined from the video recording, and / or the result of the permission process is negative, then the tracking unit 14 sets the permission status of person P in the video recording to negative.

[0131] like Figure 3 As shown in c, personnel P moves from permitted area 28 toward door 18. Tracking unit 14 further tracks the movement of personnel P (step S6).

[0132] Meanwhile, in step S7, the tracking unit 14 evaluates whether the door 18 should be opened, as well as various safety conditions or general safety conditions corresponding to the person P.

[0133] The safety conditions discussed below can be monitored separately by tracking unit 14, in combination with any other safety conditions, or not in combination at all.

[0134] The first security condition is the integrity of the door-related security zone 36. The door-related security zone 36 is... Figure 3 c and d are indicated by dashed lines, and their shape and size depend on the kinematic properties of one, several, or all unauthorized persons in the video, particularly their walking speed, direction of walking, and distance to the door.

[0135] The area of ​​the door-related security zone 36 in the video corresponds to the area in front of door 18, specifically the area directly adjacent to door 18. The door-related security zone does not need to cover the entire width of door 18, but rather the area in front of the opening passage of door 18.

[0136] For clarity, even though it is represented as a rectangle in the figure, the shape can be any other shape, such as an ellipse, a circle, or the shape of a probability distribution (such as a Gaussian distribution).

[0137] The shape and size of the door-related security zone 36 can depend on the width W of the passage, i.e., the opening width of the door 18. For example, if the width W increases, i.e., the door is opened further, the size of the door-related security zone 36 also increases.

[0138] The integrity of the door-related security zone 36 is given, which means that the first security condition regarding the integrity of the door-related security zone 36 is satisfied if there are no unauthorized personnel within the door-related security zone 36. Unauthorized personnel should be understood as personnel who do not have a positive authorization status.

[0139] If an unauthorized person is (partially) within the door-related security zone 36, then the integrity of the door-related security zone 36 is no longer guaranteed, and the security conditions regarding the integrity of the door-related security zone 36 are not met.

[0140] Therefore, the tracking unit 14 determines from the video recording whether a person exists in the door-related security zone 36 and whether the person has a valid permission status. Based on this, the tracking unit 14 determines in step S7.1 whether the first security condition regarding the door-related security zone 36 is met.

[0141] The second security condition involves a dynamic personal security zone 38, in Figure 3 c, d, and e are represented by dashed lines.

[0142] Unlike the door-associated security zone 36 (which is static in position and optionally varies only in size and shape), the dynamic personal security zone 38 is assigned to the person P in the video recording and moves dynamically with that person.

[0143] The dynamic personal safety zone 38 is an area in the video (and thus also an area in real life) that surrounds a person, especially a person with a positive permission status.

[0144] The dynamic safety zone 38 has a predefined shape and size around the corresponding person, but moves in the same way as the corresponding person moves.

[0145] As explained regarding door-related security zone 36, the shape and / or size of dynamic security zone 38 may also depend on the current width W of the opening passage of door 18.

[0146] For example, the shape and / or size of the door-related security zone 36 and / or the shape and / or size of the dynamic security zone 38 are always selected such that the door 18 can be safely closed between authorized personnel passing through the passageway through the door 18 and unauthorized personnel following behind the authorized personnel just outside the respective security zones 36, 38.

[0147] As with door-related security zone 36, if there are no unauthorized personnel within dynamic security zone 38, then the integrity of dynamic security zone 38 is given and the second security condition is met. If there are unauthorized personnel (partially) within dynamic security zone 38, then the integrity of dynamic security zone 38 is not given, and the second security condition is not met.

[0148] Therefore, in step S7.2, the tracking unit 14 determines whether the person is within the dynamic safety zone 38 of the person P approaching the door, and determines whether the second safety condition regarding the dynamic safety zone 38 is met.

[0149] If there is more than one person P in the recording, each person P (at least each authorized person P) is assigned a separate personal dynamic security zone 38. Therefore, there may be multiple security zones 38.

[0150] exist Figure 3 In the case shown in c, no other personnel are in the door-related security zone 36 and the dynamic security zone 38, so that the tracking unit 14 determines in step S7 that the security conditions are met.

[0151] Then, in step S8, the tracking unit 14 determines that when the person P approaching the door 18 has a positive permission status and meets the safety conditions, the door 18 will be opened for the person P.

[0152] Furthermore, the tracking unit 14 determines the location, time, and width at which the door 18 will be opened, i.e., the location of the passage created for person P and the width W that the passage should have. To this end, the tracking unit 14 evaluates the position of person P relative to the door 18 in the video recording.

[0153] On the other hand, if personnel P does not have a valid permission status or does not meet any security conditions, the tracking unit 14 will determine that door 18 should remain closed.

[0154] In step S9, the tracking unit 14 transmits the expected opening width (i.e., the width W of the passage) of the door 18, and the location where the passage is formed along the trajectory of the door 18, to the control unit 22.

[0155] The control unit 22 then alternately controls one or two drive units 24 to move the door leaf 20, thereby achieving the desired passage of the door 18. For example... Figure 3 As shown in d, a passage is formed directly in front of person P, and person P can pass through the passage without changing their walking speed or direction.

[0156] Alternatively, the tracking unit 14 can directly control the drive unit 24.

[0157] The passageway should be formed along the path of door 18 (i.e., the trajectory of door leaf 20). To achieve this, door leaves 20 can be driven independently of each other and can even move beyond the middle of the door's pathway. In other words, door leaves 20 can even move further inward than the normal closed position of door 18.

[0158] In step S10, the tracking unit 14 and / or control unit 22 determine from the video recording that person P has passed through door 18. In response, the tracking unit 14 and / or control unit 22 control the drive unit 24 to actuate door leaf 20, thereby closing door 18 directly behind person P (see [link]). Figure 3 (e and f in the text).

[0159] Closing of door 18 can be performed by control unit 22 and / or controller 27 of camera 26 as part of the integrated security function of door 18.

[0160] Figure 5 a to d in the diagram illustrate a second situation that may occur during the operation of the personnel separation device 10 according to the method of the present invention.

[0161] Contrary to the situation discussed above, in addition to the person P who is allowed to pass through door 18, there is a second person in the field of view F of camera 26 and thus in the recording.

[0162] In the following text, the other person is referred to as Intruder I, which is only for the purpose of discussion and not as another customer who has not yet paid and may disparage the store.

[0163] Therefore, there are two people in the video: person P and intruder I.

[0164] Tracking unit 14 identifies the two people as separate individuals. For each person, tracking unit 14 sets a permission state, identifies attributes, and tracks their movement over time. Therefore, steps S2 to S5 are performed for each person. In other words, each person in the video recording has a separate permission state, and their movement is tracked individually by tracking unit 14.

[0165] Therefore, after performing the authorization action, person P will receive a positive authorization status from tracking unit 14. Conversely, intruder I did not perform an authorization action, at least not an authorization action that would lead to a positive result in the authorization process, so tracking unit 14 sets intruder I's authorization status to a negative status. Therefore, intruder I is an unauthorized person.

[0166] The movement of authorized personnel P and Figure 3 The situation is the same. Intruder I also approaches the door, but at a slower pace and at a greater distance from authorized person P.

[0167] Therefore, intruder I did not violate the dynamic security zone 38 because there was sufficient distance between him and person P.

[0168] Furthermore, person P arrived at door 18 much earlier than intruder I, causing intruder I to be significantly away from the door-related security zone 36 when the door was opened.

[0169] Thus, the safety condition is met, personnel P has a positive permission status and approaches the door, thereby the tracking unit 14 determines that the door 18 should be opened. The tracking unit 14 then controls the control unit 22 as described above to initiate the process of the door 18 being opened and personnel P passing through the door. Figure 5 (b)

[0170] like Figure 5 As shown in c and d, since door 18 is closed directly behind person P, intruder I cannot pass through the passage of door 18 immediately after person P passes through it.

[0171] Furthermore, door 18 will not be opened for him because intruder I does not have a valid permission status.

[0172] Thus, licensed person P has successfully separated from unlicensed person I.

[0173] Figure 6 a and b in the text show the relationship with Figure 5 The situation is slightly different. In this case, intruder I follows authorized person P very closely and violates the integrity of authorized person P's dynamic security zone 38.

[0174] Therefore, in step S7.2, the tracking unit 14 determines that the integrity of the undefined dynamic security zone 38 is not met, thus failing the second security condition regarding the dynamic security zone 38.

[0175] Door 18 cannot be opened because one security condition is not met, as intruder I can also pass through the passageway of door 18. Therefore, in order for authorized person P to pass through door 18, the intruder must back away.

[0176] Therefore, in step S9, the tracking unit 14 controls the control unit 22 to keep the door 18 closed. If necessary, the control unit 22 can correspondingly control the drive unit 24.

[0177] In addition, the control unit 22 and / or the tracking unit 14 can control the signal device 40 to indicate that the intruder I intends to pass through the door 18 and therefore cannot open the door.

[0178] The signal device 40 may be an optical signal device 42 (such as a light source) and / or an acoustic signal device 44 (such as a loudspeaker).

[0179] The signal device 40 may be part of the personnel separation device 10, the automatic door system 16, or a building in which the door system 16 is installed.

[0180] Figure 7 a to c in the figures illustrate a third scenario during the operation of the personnel separation device 10 according to the method of the present invention.

[0181] In this case, the personnel separation device 10 (more precisely, the authorization system 12) includes two terminals 32.

[0182] Terminal 32 may be within the same licensed area 28, or two separate licensed areas 28 may be part of the licensed system 12.

[0183] In the scenario shown, individuals P1 and P2 who wish to pass through door 18 perform a permission action at either terminal 32.

[0184] As previously described, the tracking unit 14 identifies each person P1, P2 in the video as a separate individual and receives the result of the authorization process of the authorization system 12 for each person P1, P2.

[0185] Since the licensing process has been performed on different terminals 32 and / or in unrelated licensing areas 28 (and the result of the licensing process includes information about the terminal that performed the licensing action), the tracking unit 14 can associate the result of the licensing process for each of the personnel P1 and P2 with the correct personnel P1 and P2 in the video recording. In addition, the attributes of personnel P1 and P2 can be matched (step S5.1).

[0186] Both permission processes are affirmative and the permission conditions are met, causing the tracking unit 14 to set the permission status of the two individuals P1 and P2 to an affirmative value, which means that both individuals are permitted.

[0187] like Figure 7 As shown in b, personnel P1 and P2 approach door 18 almost simultaneously. When both personnel P1 and P2 are authorized, even if personnel P1 and P2 may be within each other's dynamic safety zone 38, the tracking unit 14 determines that the door should be opened, as... Figure 7 As shown in c in the figure.

[0188] Therefore, the tracking unit 14 begins to open the door 18 with a width W, which creates a passage that allows two people P1 and P2 to pass through the door 18 simultaneously, without changing their walking speed.

[0189] Figure 8 a to d in the figures illustrate another instance of the personnel separation device 10 during operation of the method according to the invention.

[0190] like Figure 8 As shown in a, the person P who is allowed to pass through door 18 and the intruder I who is approaching the door at the same time are in the field of view F of camera 26.

[0191] Therefore, the tracking unit 14 identifies person P and intruder I as separate individuals in the video recording.

[0192] In this case, a third security condition is used. The third security condition involves personnel integration.

[0193] In the sense of this invention, the fusion of persons describes the following process: first, two different and separate persons are identified as being close by the tracking unit 14, and at a later point in time, only one person can be identified in the video, while the other person does not leave the field of vision F by crossing the boundary of the field of vision F.

[0194] The third security condition regarding personnel fusion is satisfied if no fusion is identified or if a fusion of one licensed person with another is identified. In any other case (i.e., a fusion of a licensed person with an unlicensed person, or a fusion of two unlicensed persons), the third security condition regarding personnel fusion is not satisfied.

[0195] exist Figure 8 In scene a, intruder I and person P are close together. Then, in Figure 8 In b, only authorized person P remains, and is part of the recording. For example, this could happen if intruder I hides behind person P or is covered by their clothing to smuggle intruder I through door 18.

[0196] exist Figure 8 In c, person P performs a licensing action at terminal 32, which indeed leads to a positive result in the licensing process.

[0197] Then personnel P approached door 18 ( Figure 8 d) in the video, and since there is no intruder I in the video, the first and second security conditions regarding static security zone 36 and dynamic security zone 38 are satisfied.

[0198] However, since the tracking unit determines in step S7.3 that the fusion of unauthorized person I and authorized person P has occurred, the third security condition regarding person fusion is not met.

[0199] Therefore, the tracking unit 14 notifies the control unit 22 that the door 18 should be closed or remain closed, and activates the signal device 40.

[0200] Figure 9 a to b in the figures illustrate another scenario during the operation of the personnel separation device 10 according to the method of the present invention.

[0201] In this situation, in the field of view F of camera 26, there is an inanimate object 46, such as a briefcase or bag, in front of door 18.

[0202] The tracking unit 14 identifies the object 46 in the video recording as a single isolated object.

[0203] like Figure 9As shown in a, the licensor P approaches object 46 and picks it up, causing object 46 and licensor P to merge into one object.

[0204] Therefore, the merging of the inanimate object and the person P has occurred, since object 46 and person P are no longer distinguishable from each other in the video recording and must be regarded as a single object or person.

[0205] In these cases, the fourth safety condition regarding the fusion of people and objects was used and evaluated in step S7.4.

[0206] exist Figure 9 In the case shown in b, authorized personnel P are allowed to merge with inanimate, previously isolated objects, thereby satisfying the fourth security condition. Tracking unit 14 thereby controls control unit 22 to open door 18 for personnel P carrying object 46.

[0207] However, a more complex version of the fourth security condition regarding the integration of objects and people is conceivable.

[0208] For example, the type of object 46 can be categorized. The fourth security condition can allow only specific types of objects to merge with licensees. Thus, disallowing an object of a certain type from merging with a licensee P may result in the fourth security condition not being satisfied.

[0209] In order for the tracking unit 14 to perform all or any of the above determinations, the tracking unit 14 includes a determination algorithm, a machine learning algorithm, a support vector machine, and / or a trained artificial neural network.

[0210] The artificial neural network of tracking unit 14 is an artificial neural network trained using training data.

[0211] The training data includes different sets of input data for various scenarios (such as those described above), as well as information on whether the door should be opened, when and where it should be opened, and how wide it should be opened in each scenario.

[0212] The input data includes the same types and data structures as those provided to the artificial neural network during its operation, as described above.

[0213] Specifically, the input data includes video footage generated by camera 26, at least one attribute of person P in the video footage, and / or the result of a licensing process.

[0214] In addition, the input data includes the expected correct output of the artificial neural network in response to each data set of the input data, particularly information about the actual movement of people in the video; the actual attributes of people in the video; a determination of whether at least one attribute of the input data matches at least one determined attribute; a determination of whether and / or which security condition is met and not met; and a determination of whether a door should be opened, when it should be opened, how wide it should be opened, and / or where it should be opened.

[0215] For training artificial neural networks, in the first training step T1 ( Figure 4 In this process, input data is fed forward through an artificial neural network. Then, the response output of the artificial neural network is determined (step T2).

[0216] The response output may include definite movement of a person in the video; definite attributes of a person in the video; a determination of whether at least one attribute of the input data matches at least one determined attribute; a determination of whether and / or which security condition is met or not met; and a determination of whether a door should be opened, when it should be opened, how wide it should be opened, and / or where it should be opened, which is determined by an artificial neural network based on input data from one of various training scenarios.

[0217] In step T3, the errors between the response output of the artificial neural network and the expected correct output (known from the training data) are determined, specifically the errors between the determined movement and the correct movement of the person in the video recording; the errors between the determined attributes and the correct attributes of the person in the video recording; the errors between the determination and the correct determination regarding whether at least one attribute of the input data matches at least one determined attribute; the errors between the determination and the correct determination regarding whether and / or which security condition is met and not met; and the errors between the determination and the correct determination regarding whether a door should be opened, when it should be opened, how wide it should be opened, and / or where it should be opened.

[0218] In step T4, the weights of the artificial neural network are changed by backpropagating the error of the artificial neural network.

[0219] Figure 10 and Figure 11 A second and third embodiment of the personnel separation device 10 according to the present invention are shown. The second or third embodiment substantially corresponds to the first embodiment, and therefore only the differences will be discussed below. Identical and functionally identical components are labeled with the same reference numerals.

[0220] exist Figure 10 In one embodiment, the personnel separation device 10 includes two automatic door systems with doors 18, each arranged in series, i.e., one door is behind the other.

[0221] The automatic door system 16 closest to the permission area 28 is hereinafter referred to as the main door system 16. The main door system 16, the permission system 12, and the tracking unit 14 correspond to the first embodiment of the personnel separation device 10 as described above.

[0222] The second automatic door system (hereinafter referred to as the secondary door system 48) has the same components as the main automatic door system 16, and in particular, it also has a camera 26.

[0223] In other words, the permitted area 28 and the secondary door system 48 (specifically its door 18) are on opposite sides of the main door system 16.

[0224] In addition, two tracking units 14 are provided, namely a main tracking unit 14 associated with the main gate system 16 and a secondary tracking unit 14 associated with the secondary gate system 48.

[0225] The field of view F2 of the camera 26 of the secondary door system 48 may not necessarily include the permitted area 28. In addition, the field of view F2 of the secondary door system 48 may or may not include the door 18 of the main door system 16.

[0226] However, personnel P who have already passed through the main gate system 16 are either directly within the field of vision F2 of the secondary gate system 48, or enter the field of vision F2 at a later time.

[0227] The secondary tracking unit 14 associated with the secondary door system 48 is connected to the primary tracking unit 14 and / or the authorization system 12 associated with the primary door system 16.

[0228] Specifically, the secondary tracking unit 14 determines the permission status of the person P in the field of view F2 of the camera 26 of the secondary door system 48 in the same manner as the primary tracking unit 14.

[0229] For example, the secondary tracking unit 14 receives the permission status of a person P passing through the door 18 from the primary tracking unit 14, so that the secondary tracking unit can easily associate the permission status received from the other tracking unit 14 with the person P identified in the video captured by the camera 26 of the secondary door system 48.

[0230] The secondary tracking unit 14 tracks the movement of one or more persons P in the video recordings of the corresponding camera 26 of the secondary door system 48, and controls the control unit 22 and / or drive unit 24 of the secondary door system 48 based on the assessment of the movement, the permission status of the persons, and other optional security conditions.

[0231] The determination of whether the door 18 of the secondary door system 48 should be opened, where it should be opened, and the width of the opening is made in the same manner as the main door system 16 (i.e., as explained with respect to the first embodiment).

[0232] If the field of view F2 of the secondary door system 48 does not include the door 18 of the main door system 16, then as explained with respect to step 5.1, the association between the person P in the video and the corresponding permission status can be completed based on the attributes of the person P.

[0233] Therefore, by setting up two doors 18, one in front and one behind, the efficiency of the personnel separation device 10 can be greatly improved, because it is much more difficult for an intruder I to pass through the two doors 18.

[0234] In practice, another security condition can be introduced for the secondary door system 48. For example, door 18 of the secondary door system 48 can be opened only if no unauthorized person passes through door 18 of the main door system 16.

[0235] according to Figure 11 The embodiments also include a main door system 16, but are different from those according to... Figure 10 Compared to the second embodiment, it has two sub-gate systems 48.

[0236] From door 18 of the main door system 16, one can directly access the doors 18 of the two secondary door systems 16. This means that a person can start from door 18 of the main door system 16 and reach either door 18 of the secondary door system 48 without passing through the door 18 of the other secondary door system 48.

[0237] In other words, after person P passes through door 18 of the main door system 16, he can choose between the two doors 18 of the secondary door system 48.

[0238] In addition to the functions of the sub-tracking unit 14 corresponding to the sub-gate system 48, the permission status of person P to the sub-tracking unit 14 may depend on the specific sub-gate system 48. Thus, even if one of the sub-tracking units 14 assigns a positive permission status to person P due to its authorization, another sub-tracking unit 14 associated with another sub-gate system 48 may assign a negative permission status, because the specific person P may not be authorized to access the area behind that specific sub-gate system 48.
