Description

  The present invention relates to an automatic ticket gate, and more particularly to an automatic ticket gate device, an automatic ticket gate method, and an automatic ticket gate system that can be used by a user who is more difficult to use at a station such as a wheelchair user than a normal user.

  In recent years, automatic ticket gates in station equipment have been judged to be passable by a user carrying a ticket such as a contactless IC card over an automatic ticket gate equipped with a contactless IC card reader / writer, There are many cases where traffic is possible.

  On the other hand, wheelchair users and the like often have difficulty in using the automatic ticket gate. The normal automatic ticket gate device is configured on the assumption that a normal user (healthy person) uses the automatic ticket gate device. For example, the speed at which a wheelchair user passes through the automatic ticket gate device is high. This is because the speed of a normal user is slower than the speed of passing through the automatic ticket gate, and the form of the user when using a wheelchair is different from that of the normal user, but the difference in form is not considered.

In response to this problem, for example, an automatic ticket gate device corresponding to a weak user of an automatic ticket gate device such as a pregnant woman, a visually impaired person, a crutch user, and an elderly person is known (for example, see Patent Document 1).

  According to the present invention, it is possible to provide an automatic ticket gate device that can be easily used by a weak user of the automatic ticket gate device without requiring a special registration procedure.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows an automatic ticket gate system 1 using an automatic ticket gate device 10 according to an embodiment of the present invention.

  The automatic ticket gate system 1 includes the automatic ticket gate device 10, a main control device (not shown) that controls the plurality of automatic ticket gate devices 10, a display device 20 provided on the automatic ticket gate device 10, and the like. The illustrated example shows a state where the wheelchair user P passes through the passage of the automatic ticket gate according to the present embodiment.

  The automatic ticket gate 10 according to the present embodiment is a device installed at a ticket gate of a facility such as a railway station or an airport, and includes main bodies 10a and 10b provided on both sides of a passage through which a user passes.

  In the automatic ticket gate apparatus 10 according to the present embodiment, entrance sensors 11a and 11b for detecting a user are arranged at the entrance of the passage, and the user who uses the automatic ticket gate apparatus 10 is detected.

  In addition, cameras 12a (first camera) and 12b (second camera) for detecting a user are arranged in front of the side surface on the passage side of the automatic ticket gate, and the user's usage mode is detected and imaged. This imaging timing is performed at the moment when the entrance sensors 11a and 11b are shielded from light. As a result, the mode of the user P of the wheelchair 30 shown in the figure is captured by each camera.

  FIG. 2 is a plan view of the automatic ticket gate shown in FIG. The imaging range of each camera 12a, 12b is indicated by a viewing angle θ.

  The form of the user P imaged in this state includes a normal user, a pregnant woman, a visually impaired person, a crutch user, a wheelchair user, and the like.

  Images captured by the cameras 12a and 12b are sent to the connected image processing units 13a and 13b, respectively. The image processing unit 13 removes a noise component from the obtained planar image, and compares it with a template image (standard pattern image) according to each user form.

  In this embodiment, it can be performed by using both a feature extraction method and a similarity method known as a pattern matching method. Further, the comparison determination result is notified to the door control units 14a and 14b.

  For example, the door control units 14a and 14b perform door control suitable for the weak user based on the comparison determination result.

  FIG. 3 is a flowchart of the automatic ticket gate apparatus 10 shown in FIG.

  It detects until the entrance sensors 11a and 11b are shielded from light (No in S1). As a result of the detection, when the entrance sensors 11a and 11b are shielded from light (Yes in S1), the cameras 12a (first camera) and 12b (second camera) are joined to the entrance sensors 11a and 11b at the shielded timing. The predetermined part which blocked | interrupted 11b is imaged (S2). The imaging range is set by setting the viewing angle θ of the camera lens.

  Images captured by the cameras 12a (first camera) and 12b (second camera) are transmitted to the respective image processing units 13a and 13b connected to the cameras 12a and 12b. By capturing images from both sides using the first camera and the second camera, it is possible to prevent the face image from being recognized erroneously because the user is facing sideways at the moment of capturing.

  Since the image processing units 13a and 13b are configured similarly, the image processing unit 13a will be described.

  The image processing unit 13a performs preprocessing and recognition processing on image data received by the camera 12a. In the preprocessing, a face image is extracted from the captured image (face image extraction process), and the image size is normalized based on the size of the extracted face image (normalization process). This face image extraction processing method can be performed, for example, by the method described in JP-A-2004-259215.

  Next, the lower image of the face image is cut out from the image normalized by the above-described method (detected image cut-out process). In the present embodiment, the lower face image is cut out because the feature of the portion below the face of the physically weak person who is the weak user is remarkable.

  Next, the image obtained by the above-described cutting process is binarized with a predetermined threshold (binarization process), and an outline is detected.

  Next, the detected image detected in this way is identified by a matching method with respect to a template image that is a standard image of a weak user.

  As this matching method, a residual method, a similarity method, and the like are known, but they can be identified by any method. A method of recognizing characteristic partial features from the extracted image is also effective, and it is possible to improve the recognition rate by supplementing the recognition result by the matching method.

  The template image according to the above-described embodiment is a database of standard patterns for standard forms of weakly used persons from the standpoint of using automatic ticket gates such as wheelchair users, crutch users, visually impaired persons, and pregnant women. is there. Further, the template image can be searched for in a storage device (not shown) which is connected to the automatic ticket gate of the present embodiment or is communicably connected to the automatic ticket gate and can be accessed by a control device which controls the automatic ticket gate. Stored (S3).

  Next, when it is recognized as a weak user by the above-described processing (Yes in S4), in this embodiment, the display device (lamp) 20 provided at the upper part of the ticket gate is turned on (S5). From now on, the station staff and passersby will be informed that the user who uses the automatic ticket gate is a weak user and call attention.

  Next, it is determined whether or not the ticket carried by the weak user mentioned above is allowed to pass. If the ticket is not allowed (No in S6), door control for the weak user is performed (S7).

  The door control for the weak user is performed, for example, by slowing the door closing speed compared to the normal speed even if the weak user is blocked due to impassability.

Portion of Feature Extraction Part for the Extracted Image In step S4, as a result of the recognition of passers-by, it is determined whether or not a passable ticket is carried by a person who is not a weak user (No in S4). As a result of the determination, if the vehicle is not allowed to pass (No in S8), normal door control is performed (S9).

  In addition, as a result of the passage permission / inhibition determination in steps S6 and S8, when the passage is permitted (Yes in S6, Yes in S8), nothing special about door control is performed.

  In the recognition of passers-by in step S3, even if a weak user is misrecognized as a normal passer-by, the effect of the misrecognition is only that the weak user is treated as a normal passer-by. As a result, it is possible to obtain convenience by the function of the automatic ticket gate as in the prior art. This means that the above-described effects can be obtained by gradually implementing the present invention on an already-operated automatic ticket gate.

  As described above, according to the embodiments of the present invention, it is possible to provide an automatic ticket gate device that is easily used by a weak user without requiring a special notification.
