    [0001] The present invention relates to an access control system and a passage control method using such an access control system.
    [0002] Access control systems are commonly used in the area of passenger transport. For example, access control systems are used in land and air transport. Thus, such systems are found in railway stations, metro stations or terminals. These access control systems comprise a corridor whose access is regulated by the opening or closing of a door. It is then appropriate to detect the passage or at least the presence of a person in the portion of the corridor that precedes the door. The opening of the door is then synchronized with the passage of the detected person. In addition, the duration of the opening of the door is adapted and limited to allow the passage of the person detected without allowing the passage of the next person whose access has not been controlled and validated. Indeed, it is desirable to allow the passage of the physical access control system only to persons holding a valid ticket, in order to avoid fraud. For this, it is known access control systems whose corridor is delimited laterally on each side by a chest. One of the chests comprises cells emitting a light beam and the other trunk comprises receiving cells placed opposite a corresponding transmitting cell. Thus, the detection of people is performed by cutting light beams. By limiting the number of cells for economic reasons, accidents occur, in particular due to a sudden and untimely closure of the door on a person. For example, in the case of an adult accompanied by a young child, small, the door may close before the passage of the child, if the child follows the adult. Similarly, if a person is carrying a large backpack or is pulling behind a wheeled baggage or stroller, which is relatively common in the case of access to transportation networks, there is the risk of inadvertent closing of the door on the bag or luggage or stroller. By simply increasing the opening time of the door, on the one hand the risk of fraud is increased, leaving a possibility of passage to unauthorized persons, and on the other hand the number of people able to cross a corridor in a room. time unit (for example for one hour) is reduced, which can affect the "fluidity" of the passage, unless to increase the number of parallel corridors.
    [0003] Thus, to ensure good security, it is necessary to have the largest possible number of cells in the vaults of the access control system. However, this imposes a significant congestion of the access control system.
    [0004] There is therefore a need for an access control system with a reduced footprint while ensuring the safety of people and reducing the risk of fraud. According to the invention, this object is achieved by an access control system comprising a corridor extending along a first direction and blocked by a door opening or closing to allow or prohibit the passage of people, based on the presence detection of persons and / or access authorization verification assigned to said persons. The access control system comprises a means for recognizing a right of access to the corridor, an optical sensor capable of imaging at least part of the access control system and positioned directly above the corridor, a controller capable of recognizing and following contours of persons and / or objects present in the corridor, with a view to a suitable door opening / closing command. The distance between the means for recognizing an access right and the door along the first direction is less than 80 centimeters. According to particular embodiments, the access control system comprises one or more of the following characteristics, taken in isolation or in any technically possible combination: the distance between the means for recognizing a right of access and the door along the first direction is less than 75 centimeters. the access control system comprises two chests delimiting at least part of the corridor along a second direction parallel to the door, the distance between the two chests along a second direction parallel to the door being less than 110 centimeters. the distance between the two chests along the second direction parallel to the door is less than 60 centimeters. the door has a thickness along the first direction, the thickness being less than 1.2 centimeters. - The optical sensor is a clean camera to operate on the principle of flight time. - The corridor is delimited by a floor, the optical sensor being at a distance from the ground along a third direction, perpendicular to the first direction and perpendicular to a second direction parallel to the door, greater than 300 centimeters. In addition, there is provided a set of access control systems comprising at least one access control system as described above.
    [0005] There is also provided a method of controlling a passage through an access control system having a corridor extending along a first direction and barred by a door opening or closing to allow or prohibit the passage of persons, depending on the presence detection of persons and / or access authorization verification assigned to said persons. The access control system comprises a means for recognizing a right of access to the corridor, an optical sensor capable of imaging at least part of the access control system and positioned directly above the corridor, a controller capable of recognizing and following contours of persons and / or objects present in the corridor, with a view to a suitable door opening / closing command. The distance between the recognition means of an access right and the door along the first direction is less than 30 centimeters. The method includes taking images of at least a portion of the access control system by the optical sensor, and controlling by the controller the opening or closing of the door based on the images taken. Other features and advantages of the invention will appear on reading the following description of embodiments of the invention, given by way of example only and with reference to the drawings which are: FIG. together, in perspective, an exemplary access control system, and - Figure 2, a plan view over the access control system of Figure 1. An access control system is presented in Figure 1. The access control system 10 is a physical access control system The access control system 10 is bidirectional type. In the case of a "bidirectional" access control system, as considered in the examples illustrated in the drawing, it may be an alternating bidirectional access control system, that is to say which during a given period authorizes the passage in one of the two senses, suitably chosen, or of a permanent two-way access control system, that is to say which at any moment authorizes the passage in both ways. In FIG. 1, the authorized direction of movement is indicated by an arrow 12. Thus, it is defined the left as being the left side of a passenger traveling in the direction of traffic and the right as being the right side of a passenger passenger traveling in the direction of traffic. The access control system 10 comprises a corridor 14, a door 16, an optical sensor 18 and a controller 20.
    [0006] The corridor 14 comprises a passage 22, a first chest 24, a second chest 26 and two recognition means 28 of an access right. The passage 22 extends mainly along a first direction X. The first chest 24 is located on the left of the passage 22 while the second chest 26 is on the right of the passage 22. Thus, the two chests 24, 26 delimit the extension of the passage 22 along a second direction Y perpendicular to the first direction X. According to the example of Figures 1 and 2, the extension d2 of the passage 22 along the second direction Y is less or equal to 110 centimeters (cm). In this case, the passage 22 allows the passage of a disabled person. Preferably, the extension d2 of the passage 22 along the second direction Y is less than or equal to 90 centimeters (cm) to reduce the risk of fraud while allowing the passage of a disabled person. Since the two chests 24, 26 are parallel, this means that the distance between the two chests 24, 26 along the second direction Y is less than or equal to 40 cm.
    [0007] Preferably, the extension d2 of the passage 22 along the second direction Y is less than or equal to 60 cm. This prevents two people from trying to pass by being side by side. The risk of fraud is thus reduced. According to the example of FIG. 1, in the direction of circulation, the right-hand box 26 has a first recognition means 28, the first recognition means being positioned at the end of the right-hand box 26 distal to the door 16. According to the example of Figure 1, in the opposite direction of the direction of movement, the left chest 24 comprises a second recognition means 28, the second recognition means being positioned at the end of the left chest 24 distal compared to the door 16.
    [0008] In the illustrated case, each recognition means 28 is a reader. The recognition means 28 is adapted to allow the passage 22 of the corridor 14 by a person when a ticket or a magnetic card conferring a right of access is presented to the reader. To confer a right of access, the ticket or magnetic card is recognized as valid by the means of recognition 28.
    [0009] Alternatively, the right chest 26 comprises a reader capable of remotely reading the identification means of said person instead of the reader device.
    [0010] In the example shown, the distance d1 between the first recognition means 28 and the door 16 along the first direction X is less than 80 cm. Preferably, the distance d1 between the first recognition means 28 and the door 16 along the first direction X is less than 75 cm.
    [0011] Advantageously, the distance d1 between the first recognition means 28 and the door 16 along the first direction X is greater than 50 cm to avoid stopping the user. The door 16 is adapted to open or close to allow or prohibit the passage of people, according to the detection of presence of persons and / or access authorization verification assigned to said persons. The door 16 extends along the second Y direction and is disposed midway from the corridor 14. This means that the door 16 is equidistant along the first direction X of each end of the trunks 24, 26 delimiting the corridor 14. The door 16 comprises two leaves 30 and 32, a left leaf 30 and a right leaf 32. The two leaves 30, 32 are made of glass. The two leaves 30, 32 are movable in the same vertical plane transverse to the corridor 14 between an open position and a closed position. The two leaves 30, 32 are adapted to move by sliding. This sliding is indicated by two arrows 34 in FIG. 1. The open position is shown in FIG. 1. In the open position, the two leaves 30, 32 are respectively retracted in the first box 24 and the second box. 26, which frees the passage through the corridor 14. The closed position is shown in Figure 2. In the closed position, the two leaves 30, 32 are brought closer to one another, so as to block the passage through the corridor 14. To achieve this particular operation, according to the example of Figure 1, each box 24, 26 comprises a control member of the movements of the leaf 30, 32 respectively. The control members are not shown in Figures 1 and 2 for the sake of simplification. The control members are adapted to control the opening and closing of the leaf 30, 32 to which these bodies are associated. The control member of the first trunk 24 is thus able to control the movements of the left leaf 30. For example, the control members are motors. Alternatively, the two leaves 30, 32 are movable between an open position and a closed position by rotation of the leaves 30, 32 around a respective axis. In this case, the two leaves 30, 32 are pivotable.
    [0012] The door 16 has a thickness el along the first direction X less than 1.2 cm. Such a thickness makes it possible to reduce the force of the impact when closing the leaves 30, 32 on a person. This therefore increases the security for one person. According to another embodiment, the door 16 comprises a single leaf. Alternatively, the door 16 is a gate. The optical sensor 18 is able to obtain one or more images of the control system 10. More specifically, the optical sensor 18 is able to image at least the passage 22 of the corridor 14. For this, according to the example of FIG. the optical sensor 18 is positioned in line with the corridor 14. In the particular case of FIG. 1, this means that the optical sensor 18 is substantially in a third direction Z perpendicular to the first two directions X and Y.
    [0013] In addition, since the optical sensor 18 is able to image at least the passage 22 of the corridor 14, this implies that the distance of the optical sensor 18 along the third direction Z relative to the ground delimiting the corridor 14 is relatively large, typically greater than 300 cm. In the example shown, the optical sensor 18 comprises a matrix detector 36 and an optical system 38. The matrix detector 36 is, for example, a CCD type detector. A CCD detector (acronym for "charged-coupled device") is a detector capable of transforming a light signal into an electrical signal.
    [0014] The optical system 38 includes, by way of illustration, lenses. In a variant, the optical system 38 comprises prisms and / or waveguides. According to another embodiment, the optical sensor 18 comprises only a matrix detector 36.
    [0015] Preferably, the optical sensor 18 is a camera operating on the principle of flight time (often referred to by the corresponding English acronym TOF for "Time of Flight"). Such a camera makes it possible to obtain three-dimensional maps or depth maps of the corridor 14. The controller 20 is capable of realizing the recognition and the tracking of contours of people and / or objects present in the corridor 14 from the images coming from of the optical sensor 18, for a suitable control opening / closing of the door 16.
    [0016] In particular, the controller 20 is able to recognize the contours of the persons engaged in the corridor 14, including the possible presence of a backpack, or a bulky object pulled by the person, or a small child accompanying said person.
    [0017] The controller 20 is also able to make an opening or closing decision according to the contours recognized and / or followed. The controller 20 comprises an electronic processing unit capable of performing the analysis and the processing of the images coming from the optical sensor 18. According to the example of FIG. 1, the controller 20 is located in the second box 26 and cooperates with the sensor optical 18, the means of recognition of an access right 28 and the control members of the movements of the leaves 30, 32. This cooperation is for example implemented by optical signal communication. The operation of the access control system 10 is now described. A person introduced into the reader 28 a ticket recognized as valid and authorizing the passage 22 of the person. The optical sensor 18 obtains images of the person passing through the passage 22. The controller 20 processes and interprets the images and the passage authorization obtained by the person to control the opening of the door 16.
    [0018] In particular, the controller 20 controls the opening of the door 16 at the moment when the authorized person is in front of the door 16 As long as the said person has not completely passed, the controller 20 maintains the opening of the door 16. As soon as the person has passed, the controller 20 controls the closing of the door 16. The previously described example of operation is the simplest use case. Other examples are also managed by the access control system 10. In some cases, the person carries a backpack or luggage, pulls a stroller or holds the hand of a child accompanying him.
    [0019] In this situation, as long as the person and what he is carrying, pulling or the child have not completely passed, the controller 20 maintains the opening of the door 16. As soon as the person has passed as well as what door, pulls or the child also, the controller 20 controls the closing of the door 16. Similarly, the access control system 10 also prevents fraud with two people closely following also called "tailgating", or if a person seeks to use the right of way granted to another person by crossing the passage 22 in the opposite direction to the direction of circulation. Thus, the access control system 10 is able to detect and discriminate a person wearing a backpack, or a person pulling a baggage or a stroller, or a person with a small child. The access control system 10 thus has a precise detection, allowing in particular to adapt the opening time of the door 16 in each case. This avoids any accidents or incidents due to an early closure. Therefore, a safe operation of the access control system 10 is ensured, the door 16 only closing after the passage 22 complete. In addition, the access control system 10 is compatible with the different applications of such systems. In particular, the access control system 10 is, for example, an alternating or permanent bidirectional system. In addition, the access control system 10 is associated with several identical systems to form a plurality of parallel corridors 14, the controllers 20 of each system ensuring the proper operation of the access doors 16 in each corridor 14 without being disturbed by the passage of people in corridors 14 adjacent. As a result, the access control system 10 can be used in all physical access control applications: public transport networks (stations, metro stations), terminals, public or private buildings, theaters, enclosures sports events, ... The implementation of the access control system 10 is simple since only an optical sensor 18 in connection with a controller 20 is involved. This also has the advantage of being relatively economical to set up.
    [0020] Many variants of the access control system 10 are possible, in particular according to the type of door 16, gate or the like equipping the access control system 10.
