Description

[0001] The invention relates to a passage control system with at least one exit door, wherein the exit door comprises a door leaf, wherein the door leaf has an entry side and an exit side, wherein the door leaf is attached to a support for suspension, wherein the door leaf comprises a transparent material, wherein a camera system is arranged on the door leaf, wherein the camera system has a movable unit, a housing, and a drive for the movable unit, wherein the movable unit and the drive are arranged within the housing, wherein the housing is immovably fixed relative to the door leaf, wherein the movable unit is movable in the vertical direction within the housing, wherein the movable unit comprises a portrait camera, wherein the movable unit defines a swept area in a front view over the travel path and the surface of the movable unit,wherein the swept area less the area of ​​the movable unit determines a released area, wherein the housing has a rear side and a front side, wherein the rear side is connected to the front side of the housing via side walls.,

[0002] Such a passage control system, for example for airports, is already known from WO 2010 / 078856 A1 and comprises a glass entrance door, a glass exit door, and a passageway between them. In front of the entrance door there is a reader for identification documents (e.g. ID cards or passports), which opens the entrance door after reading a presented identification document, in particular an ID photo. The person to be identified then passes through the open entrance door, which then closes again. They are now in the passageway and stand in front of the entrance side of the still closed exit door. A camera system is arranged on the exit side of the exit door and comprises a height-adjustable unit with a portrait camera and a screen.The height-adjustable unit is positioned at the head height of the person to be identified, allowing the person to view their own camera image on the screen and, if necessary, correct it upon instruction. A processing unit compares the camera image with the scanned ID photo and opens the exit door if there is a match.

[0003] The camera system from WO 2010 / 078856 A1 comprises a drive mounted on the exit side of the exit door near the pivot axis, which supports the movable unit. The movable unit is enclosed and, for mobility, is not attached to the door leaf, but is rigidly connected via two arms to a guide carriage on a guide rail of the drive. A disadvantage is that the movable unit and the guide carriage are relatively unprotected from the environment. Dust can therefore quickly get between the guide carriage and the guide rail in the area of ​​the guide carriage. Furthermore, the preferably fast-moving unit can injure curious children.

[0004] In practice, it is therefore common practice to arrange the movable unit together with the drive in a housing of the camera system. This housing protects the movable unit and the drive from the environment and comprises a front and a rear panel connected by side walls. The housing forms an enclosed space, which contributes significantly to the longevity of the movable unit, and especially the sensitive drive, and also complements the overall appearance of the exit door or camera system.

[0005] Sometimes ID photos are outdated, so that even under optimal shooting conditions (adequate lighting, multiple individual shots, correct height, etc.) and with the latest artificial intelligence or algorithms, the camera image cannot be matched to the ID photo. For this reason, border guards are often stationed behind the checkpoints to carry out manual checks if necessary. Another task of the border guards is to monitor the checkpoint area. A disadvantage of these known systems in practice is that the border guards do not have an unobstructed view into the checkpoint because the housing, which is quite large due to its mobility, blocks the view into the checkpoint. The invention is therefore based on the task of offering border guards better monitoring of the checkpoints.

[0006] This object is / are achieved by a passage control system with at least one exit door, wherein the exit door comprises a door leaf, wherein the door leaf has an entry side and an exit side, wherein the door leaf is attached to a support for suspension, wherein the door leaf comprises a transparent material, wherein a camera system is arranged on the door leaf, wherein the camera system has a movable unit, a housing and a drive for the movable unit, wherein the movable unit and the drive are arranged within the housing, wherein the housing is immovably fixed relative to the door leaf, wherein the movable unit is movable in the vertical direction within the housing, wherein the movable unit comprises a portrait camera, wherein the movable unit defines a swept area in a front view over the travel path and the surface of the movable unit,wherein the swept area less the area of ​​the movable unit determines a released area, wherein the housing has a rear side and a front side, wherein the rear side is connected to the front side of the housing via side walls, characterized in that the rear side of the housing is transparent over at least a portion of the swept area.

[0007] The invention is based on the realization that there are numerous ways to improve the surveillance of the passage. For example, it is possible to position several surveillance cameras at different locations within the passage. This fundamentally enables significantly better surveillance, which also does not require border guards on site. However, it has been found that this type of surveillance is tiring for border guards and subsequently provokes negligence. It has also been found that this type of surveillance is too complex even for artificial intelligence, so this type of surveillance does not appear feasible in the foreseeable future.

[0008] Another option for better monitoring of the passages is to place the camera system on the side walls of the passage instead of at the exit door, so that the glass exit door ensures a clear view of the passage for border guards. However, this has the disadvantage that the people to be identified do not instinctively run to the exit door and stop in front of it, but must be guided to the camera system on the side wall. Guidance can be provided visually and / or acoustically, for example. However, it has been found that this causes delays in the process, significantly reducing throughput.

[0009] In particular, it was found that an at least partially transparent camera system provides such a view into the passage area that border guards stationed behind the checkpoint find it sufficient for their work. The border guards can observe and interpret all significant movements of the persons to be identified. This type of surveillance is significantly less tiring for border guards and simultaneously allows for a high throughput of persons to be identified. As a result, the task mentioned above is solved particularly satisfactorily.

[0010] The object mentioned above is also achieved by a passage control system with at least one exit door, wherein the exit door comprises a door leaf, wherein the door leaf has an entry side and an exit side, wherein the door leaf is attached to a support for suspension, wherein the door leaf comprises a transparent material, wherein a camera system is arranged on the door leaf, wherein the camera system has a movable unit, a housing, and a drive for the movable unit, wherein the movable unit and the drive are arranged within the housing, wherein the housing is immovably fixed relative to the door leaf, wherein the movable unit is movable in the vertical direction within the housing, wherein the movable unit comprises a portrait camera, wherein the movable unit defines a swept area in a front view over the travel path and the surface of the movable unit,wherein the swept area less the area of ​​the movable unit determines a released area, wherein the housing has a rear side and a front side, wherein the rear side is connected to the front side of the housing via side walls.,

In the side view according to Fig. 3 a preferred thickened region 40 of the side wall 13a can also be seen, which, for example, has a cable opening 41 in a lower section.

[0042] The transparent opening 39 from the front view to Fig. 3is preferably formed as a hole that is covered by the transparent material of the door leaf 2. The transparent opening 39 is preferably designed such that it corresponds to, or substantially corresponds to, a swept area of ​​the movable unit 6. The swept area minus the area of ​​the movable unit 6 in a front view results in an exposed area 10, through which, in this exemplary embodiment, both the person to be identified and persons from the exit side can look through.

[0043] In Fig. 4A rear view of the camera system 5 is shown, wherein a rear panel 43 has been omitted in this figure to reveal the inner workings of the camera system 5. The inner workings are primarily a drive 8, which ensures the mobility of the movable unit 6. The drive 8 comprises, in particular, an electric motor 20 in the form of a stepper motor with a brake, a guide rail 16 with a toothed belt 46, a support rail 19, and a guide carriage 17 on the guide rail 16. Other components of the drive not shown here can be, for example, a motor controller or a DC voltage supply.

[0044] The electric motor 20 of this embodiment may draw a rated current of 4 A and exert a holding torque of 3.5 Nm, while the step angle may be 1.8°. The electric motor 20 drives the toothed belt 46, which is arranged vertically and to which the guide carriage 17 is connected. The guide carriage 17, in turn, is connected to the movable unit 6, which in this embodiment also has a cable cover 38. The cable cover 38 is preferably also connected to the support rail 19, so that the movable unit 6 is mounted on rails 16, 19 on both sides, which provides additional stability.

[0045] In this embodiment, the cable cover 38 contains cables for a 24 V power supply, an RS485 bus, a CAN bus, an Ethernet cable, and a ground cable. The cables are conveniently routed from the screen 14 or the cameras 9, 42 through the cable cover 38 to a drag chain 18. Fig. 4 It can be seen that the drag chain 18 occupies a certain amount of space laterally along the guide rail 16, creating the thickened area 40. The drag chain 18 ensures a minimum radius for cable bends, thus protecting the cables. The cables are guided within the drag chain 18 to a preferred upper transfer point 47 of the drag chain 18 and from there, statically fixed downwards.

[0046] Further components of the drive 8, such as the motor control or the 24 V DC power supply, are preferably located within the side wall 13c and further preferably below the electric motor 20. Some of the cables are expediently led through the cable opening 41 in Fig. 4 led to the outside, including the ground cable, at least one power supply cable, and the Ethernet cable. The latter preferably transmits the captured portrait photos to a processing unit of the access control system or control system or a higher-level server. Finally, a lighting control unit 37 is arranged in a lower area, which is connected to the lighting device 22.

[0047] In Fig. 5 The rear view of the camera system 5 is shown, although in contrast to Fig. 4the rear panel 43 completely covers the drive 8. The rear panel 43 has a window opening 44, which in this exemplary embodiment is made of a transparent plastic, for example polycarbonate. The dimensions of the window opening 44 of the rear panel 43 correspond to the transparent opening 39 on the front. In this way, the camera system 5 ensures transparency both when looking into the passage 36 and when looking out of it. This reduces the feeling of the people to be identified that they are locked in. In particular, however, border guards on the exit side of the exit door 1 have a better view into the passage 36 and can, if necessary, better observe the people to be identified there and better interpret their actions.

[0048] The passage control system operates as follows: A person to be identified, for example, a passenger in an airport building, approaches the passage control system. The display 26 signals with a green field that the person can enter the passage control system. The person approaches the reader, recognizes the intuitively displayed instruction on the screen 24 of the reader 23, and then places their identification document on the scanner 25. The data from the identification document is read and transferred to a processing unit. The entrance door 15 then opens inward, allowing the person to enter passage 36.

[0049] The entrance door 15 then closes again, and the person is monitored by the surveillance camera 30. Due to the design of the passage control system, in particular due to the exit door 1 being intuitively recognized as the exit door, the person approaches the exit door 1. In this exemplary embodiment, the opening of the entrance door 15 also activates facial recognition of the camera system 5, which uses the recordings from the live image camera 42. Since faces can already be recognized as faces from a distance of several meters, the camera system 5 of this exemplary embodiment strives to always keep the face of the approaching person approximately in the center of the recording field of the live image camera 42. As a result, the movable unit 6 adjusts its height to the height of the person to be identified with each step of the approaching person.As a result, the movable unit 6 moves more smoothly and evenly, so that it does not have to move quickly until the person is standing directly in front of the exit door 1.

[0050] It is highly preferred that the screen 14 of the camera system 5 shows that the person is being enticed to move until their face is centered within the recording field of the live image camera 42 or the portrait camera 9. This can be achieved, for example, by the screen 14 displaying markers within which the person's face must be located. For this purpose, the live image of the live image camera 42 is transmitted to the screen 14, so that the person feels as if they were facing a mirror.

[0051] In this exemplary embodiment, the camera system 5 also uses the live image camera 42 to determine whether the face of the person to be identified is sufficiently illuminated. For this purpose, images from the live image camera 42 are transmitted to the lighting controller 37, which checks whether stronger or weaker lighting is required. A corresponding signal is then output to the lighting device 22 to adjust the lighting. As soon as the camera system 5 or the lighting controller 37 registers not only the correct position of the face but also the correct illuminance, a trigger signal is output to the portrait camera 9, which then takes a portrait shot of the person to be identified. The portrait camera 9 has a relatively high resolution, allowing, for example, portrait shots with 13 MP. In contrast, the resolution of the live image camera may be only 2 MP.

[0052] The portrait image is then transmitted, preferably via the Ethernet cable, to the processing unit or compared with the read image of the identification document. This comparison may be performed, for example, using artificial intelligence in the form of a neural network. If the read portrait of the person to be identified matches the portrait image captured by the portrait camera 9, the exit door 1 opens by an electric motor actuating the pivot axis 32, and the door leaf 2, together with the camera system 5, is swung outward.

[0053] Optionally, before or after the portrait is taken, but in any case before the exit door 1 is opened, the instruction can be displayed on the screen 14 that the person should place their hand or a finger of the hand on the sensor 35 for hand biometrics. The fingerprint or palm print determined in this way can then also be compared with the read data set. In this way, greater certainty in the identification of persons can be achieved through a double check. It is also conceivable that these two identification methods could be used alternatively. If, for example, the read portrait photo is out of date but a fingerprint is stored in the identification document, a successful comparison of the portrait photos can be dispensed with and reliance can be placed on the successful comparison of the fingerprint instead.

[0054] If a successful automatic comparison is not possible, there is the option of transmitting the portrait image and the extracted portrait image to a border guard for manual review. If the guard determines that both images belong to the same person, they can manually open exit door 1. Alternatively, they can also manually review the identification document and visually inspect the person to be identified. At the latest, exit door 1 will then open for the newly identified person, whereupon the transit control system is cleared and, after exit door 1 closes, again signals readiness for admission via display 26.
