Description

  The present invention relates to an automatic ticket gate that reads a ticket medium such as a non-contact IC card, a magnetic card, and a magnetic medium, and executes a ticket gate process for determining whether or not it can pass.

  Conventionally, automatic ticket gates are installed in railway stations. This automatic ticket gate reads the ticket information from the ticket media possessed by the entering user, determines whether or not to enter, and if so, writes the entrance station and entry time in the ticket media and permits entry. . In addition, when a user gets off and participates, the automatic ticket checker at the disembarking station reads the ticket information from the ticket medium, performs fare calculation, etc., and determines whether or not to enter. Allowed to pass.

  In recent years, contactless IC cards have become widespread as such ticket media. The non-contact IC card can be charged with a monetary value, and the fare is subtracted from the remaining amount charged when passing through the automatic ticket gate. The automatic ticket checker displays the remaining amount when such a non-contact IC card is used. Thereby, the user can always confirm the remaining amount and can conveniently use it by charging the monetary value before the remaining amount becomes insufficient.

  This non-contact IC card ticket medium has become more expensive as it can be recharged. A user who has charged a large monetary value has a desire to prevent others from seeing the remaining amount display when passing through an automatic ticket gate. This is because if the remaining amount display is peeped by the users before and after or the user of the adjacent passage, the user has a concern that if the remaining amount display is expensive, the user may be stolen. . For this reason, it is preferable not to show the remaining amount display to a third party other than the principal.

  On the other hand, as a technique for preventing peeping by a third party, a technique for preventing peeping on an ATM touch panel has been proposed (see Patent Document 1). This Patent Document 1 describes that a face image detecting means for detecting a face image is provided, and when a plurality of face images are detected, a peeping prevention operation such as a display stop or a warning sound is performed. This is said to prevent peeping.

  Further, the above document describes that a peeping prevention operation is performed when a plurality of face images are detected and at least one face image does not coincide with all face images registered in advance. Yes. Thereby, while it can be confirmed by a plurality of people, it is said that peeping by other people who are not registered can be prevented.

  In addition, the above document describes that the face orientation is detected and face images not facing the display means are excluded from the count. Thereby, it is supposed that a peeping can be appropriately prevented by excluding a face image having a low possibility of peeping.

However, the technique described in Patent Document 1 is not suitable for an automatic ticket gate. That is, for an ATM that a user uses stationary, the automatic ticket gate is used while the user passes through, and it is required that the user is not stationary unless there is a problem. Also, since ATM is used for depositing and withdrawing cash for the user, even if it takes a little trouble to the user, there is a high room for acceptance if the safety is high. For this reason, it is possible to capture and register a user's face image in advance. On the other hand, since the automatic ticket gate is only required to pay the boarding fare when using the railway every day, it is very important that the ticket gate is highly convenient for the user. For this reason, there is a problem that it is not always appropriate to apply the technique described in Patent Document 1 to an automatic ticket gate as it is.
JP 2006-259930 A

  In view of the above-described problems, the present invention provides an automatic ticket gate that can prevent peeping of the remaining amount display by another person without imposing a procedural burden on the user, and to improve user satisfaction. Objective.

  The present invention includes a reading unit that reads ticket information from a ticket medium, an intruder face information acquiring unit that acquires intruder face information of a user who enters the ticket medium, and the intruder face information. A ticket gate processing means for performing ticket gate processing based on the ticket information, a remaining amount display means for displaying a remaining amount stored in the ticket medium after the ticket processing, and a remaining amount display means. Confirmer face information obtaining means for obtaining the confirmer face information of the person who confirms the display content, and display permission control means for displaying the remaining amount on the remaining amount display means if the confirmer face information and the intruder face information match. It is an automatic ticket gate equipped with.

  The reading means reads / writes information from / to a non-contact IC medium reader / writer that communicates with a non-contact IC medium, an IC medium reader / writer that reads / writes information from / to a contact IC medium, or a magnetic medium It can be configured by a device that can read information from a ticket medium such as a magnetic medium reader / writer.

  According to the present invention, it is possible to provide an automatic ticket checker that can prevent peeping of the remaining amount display by another person without imposing a procedural burden on the user, and the satisfaction of the user can be improved.

As an aspect of the present invention, the display permission control means may be configured to erase the remaining amount display displayed on the remaining amount display means when the confirmer face information does not match the intruder confirmation information.
Accordingly, the remaining amount can be displayed only when the user himself / herself is in a position where the remaining amount display can be confirmed, and peeping by others can be prevented more reliably.

  Further, as an aspect of the present invention, the storage means stores a plurality of the intruder face information in association with the remaining amount, and the display availability control means performs the erasure of the remaining amount display. However, if the confirmer face information matches any one of the plurality of intruder confirmation information, the remaining amount corresponding to the confirmed confirmer face information can be displayed on the remaining amount display means.

  A plurality of intruder face information stored in the storage means, or a plurality of intruder face information determined by the display availability control means to match or not, are set for a predetermined number of people from the last ticket gate process, or the ticket gate process It can be set to an appropriate amount, such as a time until a certain period of time has elapsed since completion.

  According to this aspect, it is possible to perform appropriate display even for the user who has returned after the ticket gate processing is completed. In addition, when a plurality of intruder face information is set to an appropriate amount, it is possible to prevent the time required for determining whether or not they match from being prolonged.

Further, as an aspect of the present invention, the confirmer face information acquisition unit is configured to determine whether or not a line of sight is directed to the remaining amount display unit from the confirmer face image, and the same person as the intruder face image has a line of sight. The remaining amount is displayed by the remaining amount display unit when it is determined that the remaining amount is displayed, and the remaining amount display is not performed in other cases.
Thereby, it is possible to display the remaining amount only while the user himself / herself is looking at the remaining amount display means (looking at the line of sight), and it is possible to more reliably prevent peeping by others.

Further, as an aspect of the present invention, if the confirmer face image acquired by the checker face image acquisition means includes at least one person who is different from the intruder face image, the remaining amount display means does not perform the remaining amount display. can do.
Thus, when the other person enters the area where the remaining amount display means can be confirmed, the remaining amount display can not be performed, and the peeping by the other person can be more reliably prevented.

  According to the present invention, it is possible to provide an automatic ticket gate capable of preventing a peeping of the remaining amount display by another person without imposing a procedural burden on the user, and to improve the satisfaction of the user.

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

  FIG. 1A is a plan view showing the external appearance of the automatic ticket gate 1, and FIG. 1B is a front view showing the external appearance of the automatic ticket gate 1.

  The automatic ticket gate 1 is configured by connecting a main body portion 2 and a bar portion 3 that are long in the passing direction (left-right direction in FIG. 1) in the passage width direction (up-down direction in FIG. 1A). On the upper surface of the main body 2, a ticket processing unit 14, an entrance-side imaging unit 15, a remaining amount display unit 18, and an exit-side imaging unit 16 are provided in order from the entrance side (the right side in FIG. 1).

  As shown in FIG. 1B, the entrance-side imaging unit 15 arranges the imaging region E1 obliquely upward on the entrance side so that the face of the user M holding the ticket on the ticket processing unit 14 can be imaged. Has been. Further, the entrance side imaging unit 15 is disposed in the vicinity of the ticket processing unit 14.

  The exit-side imaging unit 16 is arranged with the imaging area E2 facing upward so that the face of the user confirming the remaining amount and the face of the other person peeking at the remaining amount display unit 18 can be imaged. Further, the exit side imaging unit 16 is disposed in the vicinity of the remaining amount display unit 18.

FIG. 2 is a block diagram showing the configuration of the automatic ticket gate 1.
The automatic ticket gate 1 includes a control unit 12, an image processing unit 11 connected to the control unit 12, a storage unit 13, a ticket processing unit 14, an entrance side imaging unit 15, an exit side imaging unit 16, and a human detection unit 17. , A balance display unit 18, a door unit 19, and a power supply unit 20.

  The image processing unit 11 extracts an intruder face image from the entrance-side captured image captured by the entrance-side imaging unit 15 and further extracts intruder face feature information, and the exit-side captured image captured by the exit-side imaging unit 16 The process of extracting the confirmer face image from the image and further extracting the confirmer face feature information and the process of determining whether or not the intruder face image and the confirmer face image match are performed by comparing the feature points. Is transmitted to the control unit 12.

The control unit 12 executes various control operations.
The storage unit 13 stores various programs and information. Further, the ticket information acquired by the ticket processing unit 14 and the intruder face feature information captured by the entrance-side imaging unit 15 and extracted by the image processing unit 11 are stored in association with each other.

  The ticket processing unit 14 is configured by a non-contact IC card reader / writer, reads ticket information from a ticket medium 7 (for example, a non-contact IC card) held over a reading portion, and stores information appropriate for the ticket medium 7. Write. The information to be written is admission information such as the admission station and admission date / time at the admission processing, and admission information indicating the remaining amount after the fare reduction and admission status at the admission processing, etc. It is good to use this information.

  The entrance-side imaging unit 15 is composed of a digital camera, and holds the ticket medium 7 over the ticket processing unit 14 on the entrance side of the ticket gate passage L (see FIG. 1), in the direction indicated by the arrow Y (see FIG. 1). ) Including the face image of the user who is about to enter, and transmits the acquired entrance-side captured image to the control unit 12.

  The exit side imaging unit 16 is configured by a digital camera, images the imaging area E2 in which the display content of the remaining amount display unit 18 can be confirmed, and transmits the acquired exit side captured image to the control unit 12.

  The human detection unit 17 includes an appropriate sensor such as a reflection type sensor or a transmission type sensor, detects a user passing through the ticket gate passage L, and transmits a detection signal to the control unit 12.

The remaining amount display unit 18 is composed of an appropriate display device such as a liquid crystal monitor, and displays information such as the remaining amount according to a control signal from the control unit 12.
The door portion 19 is constituted by an appropriate drive device such as a motor and an opening / closing door, and opens and closes according to an opening / closing control signal from the control portion 12.
The power supply unit 20 supplies operating power to each unit.

FIG. 3 is a flowchart showing an operation performed by the automatic ticket checker 1 while one user passes through the ticket check passage once.
The control unit 12 of the automatic ticket gate 1 receives the ticket medium 7 by the ticket processing unit 14 and reads the ticket information (step S1).

  When the ticket medium 7 is received, the control unit 12 performs imaging by the entrance-side imaging unit 15 and acquires an entrance-side captured image (step S2). The entrance-side captured image is transmitted to the image processing unit 11 through the control unit 12, and the intruder face image information is extracted by the image processing unit 11 to extract the intruder face feature information. The information is stored in the storage unit 13 in association with the ticket information acquired in S1.

  In addition, what is memorize | stored at this time is good also as an entrance side captured image or an intruder face image. In addition, since the position of the intruder face image in the entrance-side captured image is within a substantially limited predetermined area, even if another person's face image exists in other areas, the other person's face image is ignored. It is preferable to acquire only the user's own intruder face image.

  The imaging timing in step S2 is preferably almost the same as when the ticket medium 7 is received by the ticket processing unit 14. Thereby, possibility that a user's face can be imaged neatly can be raised.

  The control unit 12 executes a ticket gate process based on the ticket information acquired in step S1 (step S3). In this ticket gate processing, if it is at the time of admission, it is determined that admission is possible if the remaining amount is greater than the minimum fare that can be entered or is in the commuter pass section, and the admission station and admission time are written on the ticket medium 7 and permitted to pass. At the time of entry, if the remaining amount stored in the ticket medium 7 is larger than the fare from the entrance station, the remaining amount of the ticket medium 7 is updated and updated to the participation state to allow entry. Also, if it is within the regular section at the time of participation, the ticket medium 7 is updated to the participation state and participation is permitted.

  When the control unit 12 detects that the user has approached the remaining amount display unit 18 by the human detection unit 17 (step S4), the control unit 12 performs imaging of the imaging area E2 by the exit side imaging unit 16 and acquires an exit side captured image. (Step S5). The exit side captured image is transmitted to the image processing unit 11 through the control unit 12, and the confirmer face image is extracted by the image processing unit 11 to extract the confirmer face feature information. Further, the approach detection in step S4 may be realized by detecting the confirmer face image by the exit side imaging unit 16, and the human detection unit 17 may not be used.

  The control unit 12 compares the confirmer face feature information acquired in this way with the intruder face feature information acquired in step S2, and if both pieces of information match to determine that they are the same person (step S6: match). ) The remaining amount is displayed on the remaining amount display unit 18 for a predetermined time (for example, 30 seconds) (step S7).

  The remaining amount display is not limited to display for a certain period of time, but is deleted when another person different from the intruder face feature information is detected as the confirmer face feature information. It may be configured to erase when no longer detected, or to erase when any of these conditions is satisfied.

  In the case of mismatch (step S6: mismatch), the control unit 12 does not display the remaining amount on the remaining amount display unit 18 (step S8) and ends the process. Even when the remaining amount is not displayed, if the pass permission is determined in the ticket gate process in step S3, the door 19 is opened and the passage is permitted. As a result, it is possible to prevent a user who does not see the balance display from being blocked.

  With the above-described configuration and operation, the automatic ticket gate 1 that can prevent a peek at the remaining amount display by another person without forcing the user to register a face image in advance is provided, and the satisfaction of the user is improved. The purpose is to improve.

  Since the user does not need to perform a special operation or preparation for the identity confirmation for showing the balance display by the balance display unit 18 only to the owner of the ticket medium 7, it can be used very conveniently. That is, in order to realize the conventional technique for preventing peeping in ATM, it is necessary to register the face image of the user in advance. On the other hand, the automatic ticket checker 1 described above needs to be registered in advance because the user is imaged when entering and it is determined whether or not the person who sees the remaining amount display unit 18 is the same person based on the captured image on the entrance side. There is no. Therefore, the user only has to pass the ticket medium over the ticket processing unit 14 as usual, and can receive the benefit of peeping prevention without any special operation.

  In addition, since the invader face feature information extracted from the entrance-side captured image and stored in the storage unit 13 is acquired when the user attempts to pass through the ticket gate passage L, for example, a plurality of uses may be made in a server or the like. This is faster and easier than accumulating information about a person and searching for it.

  Also, since the user's face is imaged every time, there is no need to update and register due to aging or injury of the face as in the case of registering face information in advance. can do.

  The invader face feature information stored in the storage unit 13 may be deleted at the timing when all the processes for the user are completed or when the next user enters. In this case, the amount of information to be stored can be reduced.

  Further, the intruder face feature information stored in the storage unit 13 may be continuously accumulated. In this case, it can be confirmed later whether or not there was a person who peeked at the remaining amount display or tried to peep.

FIG. 4 is a flowchart illustrating an operation performed by the automatic ticket gate 1 according to the second embodiment while one user passes through the ticket gate passage once.
Since the configuration of the automatic ticket gate 1 is the same as that of the first embodiment, detailed description thereof is omitted.
Further, steps S11 to S15 are the same as steps S1 to S5 of the first embodiment, and thus detailed description thereof is omitted.

The control unit 12 compares the intruder face feature information acquired in step S12 with the confirmer face feature information acquired in step S15 (step S16).
If both pieces of information match and it is determined that they are the same person (step S16: match), the control unit 12 waits until the line of sight of the confirmer faces the remaining amount display unit 18 (step S17: No). Here, in order to confirm the line of sight, the exit-side imaging unit 16 performs imaging every predetermined time, and processes each captured image one by one to determine whether the line of sight is directed.

When the line of sight is directed (step S17: Yes), the control unit 12 displays the remaining amount on the remaining amount display unit 18 (step S18).
The control unit 12 detects whether or not the other person's confirmer face feature information exists in the exit side captured image (step S19). If there is no other person (step S19: No), the user's own line of sight is displayed. Until it is removed from the remaining amount display unit 18 (step S20: No).

  If there is other person's confirmer face feature information in the exit side captured image (step S19: Yes), or if the user's gaze is off (step S20: Yes), the control unit 12 displays the remaining amount display unit 18 The remaining amount display is erased (step S21), and the process ends.

  If there is a mismatch in step S16 (step S16: mismatch), the control unit 12 does not display the remaining amount on the remaining amount display unit 18 (step S22) and ends the process. In the case of a mismatch here, not only the case where the intruder face feature information and the confirmer face feature information are one person and they do not match, but also the confirmation of multiple people for one intruder face feature information. The case where human face feature information exists is also included. In other words, if one person confirms another person, it is inconsistent.

By the above operation, in addition to the effects of the first embodiment, it is possible to further prevent the remaining amount displayed on the remaining amount display unit 18 from being looked into by others.
In addition, since the remaining amount is displayed only while the user's line of sight is facing, the display time can be minimized and it is possible to prevent peeping more effectively.
Further, since the remaining amount display is erased when another person is detected, it is possible to prevent the remaining amount from being read even for an unexpected peep.

  In the second embodiment described above, steps S11 to S13 and steps S14 to S21 may be separated and executed independently. In this case, the person photographed image acquired in step S12, the intruder face image extracted from this, or the intruder face feature information is associated with the ticket information (or remaining amount) after the ticket gate processing for a plurality of persons or a certain amount. It is good to have a configuration for storing the period. Then, in the comparison of the person images in step S16, one of the invader face feature information matches the confirmer face feature information using a plurality of people from the end of the intruder face feature information permitted to pass in the ticket gate process. In this case, the remaining amount display in step S18 may be performed.

  As a result, not only the principal can confirm the remaining amount display when passing through the ticket gate process, but also the user after the completion of the passage can return and confirm the remaining amount display. Even in this case, since the remaining amount is not displayed by another person, peeping can be prevented. Therefore, it is possible to achieve both improvement of the security level by preventing peeping and improvement of user convenience.

  In addition, since the confirmation person face feature information is not compared with all the intruder face feature information, it is compared with a certain amount of the entry person face information from the end, so the time required to determine whether or not they match It is possible to prevent a long time.

  Moreover, the remaining amount can be displayed again only for the automatic ticket gate 1 that the user has passed, instead of displaying the remaining amount for any user who has returned after passing.

  Note that step S17 can be omitted. If omitted, the remaining amount can be displayed by the person regardless of whether or not the line of sight is facing. If not omitted, the remaining amount is displayed only when the person is and the line of sight is facing. Can do.
