Description

Embodiments of the present invention relate to a ticket gate, a ticket gate system, and a program.

Ticket gates installed at public transport stations and the like read information from IC cards touched to a reader/writer, and execute passage control according to the IC judgment result based on the read information. In recent years, various technical proposals have been made for ticket gates that use face recognition judgment results in addition to IC judgment results. Ticket gates that use face recognition judgment results are equipped with a camera installed facing the user entering the ticket gate passage, and execute passage control according to face recognition judgment based on face image information captured by the camera in addition to the IC judgment result.

JP 2021-47672 A

The ticket gate writes passage information, etc., to the IC card presented by the user according to each judgment result. If the IC card goes out of the communication range of the reader/writer before the reader/writer finishes writing the information to the IC card, the IC writing is incomplete. In response to this incomplete IC writing, the ticket gate outputs an alert, etc., to encourage the user to retouch the IC card, and the user retouches the IC card against the reader/writer. The ticket gate uses the retouching of the IC card as a trigger to execute a retry process in response to the incomplete IC writing.

However, when a user re-touches their IC card, they may turn around while in the ticket gate passage. Because the camera for facial recognition is installed to capture the face of the user facing the direction of travel, if the user turns their back to the camera, the camera cannot capture the user's face, and an appropriate facial recognition judgment cannot be made.

Ticket gates are required to perform smooth ticket gate processing in a variety of anticipated scenarios. There is a demand to make the above-mentioned retry processing as smooth as possible so as not to cause congestion at the ticket gates.

The problem that the embodiments of the present invention aim to solve is to provide a ticket gate, a ticket gate system, and a program that enable smooth retry processing.

The ticket gate of the embodiment includes a media processing unit, a memory unit, and a control unit. The media processing unit reads media identification information from an information storage medium, and writes write information to the information storage medium from which the media identification information was read. The memory unit stores the media identification information. The control unit instructs the information storage medium from which the first medium identification information is read to write information in response to a first processing result of a first medium determination process based on the first medium identification information read from the information storage medium and a first biometric authentication process based on a comparison between the first acquired biometric information acquired in response to the reading of the first medium identification information and the first registered biometric information registered in response to the first medium identification information, and instructs the information storage medium from which the first medium identification information is read to write information when the first medium identification information is read after the detection of incomplete writing, and instructs the information storage medium from which the second medium identification information is read to write information in response to the detection of incomplete writing when second medium identification information different from the first medium identification information is read after the detection of incomplete writing, to write information in response to a second medium determination process based on the second medium identification information and a second processing result of a second biometric authentication process based on a comparison between the second acquired biometric information acquired in response to the reading of the second medium identification information and the second registered biometric information registered in response to the second medium identification information.

The following describes in detail the ticket gate system consisting of the ticket gate machine and the management server with reference to the drawings. Note that in the following embodiments, parts with the same numbers perform similar operations, and will not be described again.

Figure 1 is a schematic perspective view of a ticket gate according to an embodiment.

As shown in FIG. 1, a ticket gate 1 is provided in the passageway through which users pass. The ticket gate 1 has a ticket gate main body 10 that is fixed to the floor, a partition 17 provided on the ticket gate main body 10 on the opposite side of the passageway, and a block body 18 that forms a passageway between the ticket gate main body 10 and the partition 17.

Here, the direction along the passage is defined as the front-rear direction, with the front side of the ticket gate main body 10 shown in Figure 1 defined as the rear, and the back side defined as the front. The direction away from the ticket gate main body 10 and the block body 18 is defined as the left-right direction, with the ticket gate main body 10 positioned, for example, on the right side of the passage, and the block body 18 positioned on the left. For example, in the example shown in Figure 1, the front side is the entrance side of the passage, and the back side is the exit side of the passage. The direction from the entrance side in front to the exit side in the back is defined as the travel direction.

In preparation for the case where users pass through a common passage from the back to the front in FIG. 1, it is preferable that the block body 18 is formed in the same configuration as the ticket gate body 10. In this case, the block body 18 as the ticket gate body 10 is reversed in the front-to-back direction from the ticket gate body 10 shown in FIG. 1.

The ticket gate 1 has a ticket insertion section 19, a ticket ejection section 20, a media processing section 14 that reads and writes to an information storage medium (hereinafter, IC card), a display section 21, a storage cover 22 for storing a camera, a camera 16 for photographing a user's face, and a gate 24. The ticket insertion section 19, the ticket ejection section 20, the media processing section 14, the display section 21, the camera 16, and the gate 24 are provided in the ticket gate main body 10. The storage cover 22 is also part of the ticket gate main body 10, and is part of a cover for covering various devices of the ticket gate main body 10.

In the configuration example shown in FIG. 1, the ticket gate main body 10 is provided with a ticket insertion unit 19 at one end (the end on the entrance side) of the top surface 23, where a ticket, for example a magnetic ticket, is inserted, and a ticket ejection unit 20 is provided in front of the display unit 21 at the other end (the end on the exit side) of the top surface 23, where a ticket is ejected that has been processed by the magnetic ticket processing unit inside the ticket gate main body 10. In addition, a storage cover 22 and a camera 16 are provided at the back side of the display unit 21. The ticket insertion unit 19 and the ticket ejection unit 20 are designed to make it easy for users to insert tickets. For example, the ticket insertion unit 19 is installed at a height that makes it easy for users of average height to insert their tickets.

As shown in FIG. 1, the camera 16 is covered with a storage cover 22 so that the user cannot see it directly. The storage cover 22 is made of plastic or resin. The storage cover 22 has an opening so that the camera 16 can capture the face of the user. The opening is covered with a filter. Although FIG. 1 shows an example in which the opening is covered with a filter, the opening does not have to be covered with a filter. In other words, the camera 16 may be installed in a state in which the user can directly view the camera 16. Although the configuration example shown in FIG. 1 shows an example in which a filter is provided, the filter does not have to be provided. The filter may be any filter that prevents the camera 16 from being directly viewed by the user and allows the camera 16 to capture the face of the user.

The medium processing unit 14 is equipped with a reader/writer that processes IC cards. The reader/writer is composed of an antenna that transmits and receives radio waves, a transmission/reception circuit, etc., and the communication range is one end (the end on the entrance side) of the top surface 23 of the ticket gate 1. The medium processing unit 14 also includes a QR reader that reads QR codes (registered trademark), and a barcode reader that reads barcodes.

For example, when a user wishing to pass through the passage of ticket gate 1 holds an IC card over a specified communication area of the reader/writer of media processing unit 14, ticket gate 1 captures the IC card held by the user and reads the information recorded on the IC card. Based on the information read from the IC card, ticket gate 1 then determines whether or not the user should be allowed to pass through. Based on the result of this determination, ticket gate 1 then controls the user's passage and writes various information resulting from the ticket gate process onto the IC card.

As shown in FIG. 1, the medium processing unit 14 is installed at an angle so that the height from the floor to the top surface 23 increases from the end on the entrance side toward the center, making it easier for users to hold the IC card. Note that the approximate midpoint between the end on the entrance side and the end on the exit side is referred to as the center.

A display unit 21 for providing guidance to users or staff is provided at the end of the top surface 23 forming the ticket gate main body 10 on the exit side. The display unit 21 is composed of a display device using, for example, liquid crystal, organic EL (Electro Luminescence), etc. The display unit 21 displays a guidance screen that informs users passing through the passage of the results of the ticket gate processing. For example, the display unit 21 displays the remaining balance charged to the IC card after the ticket gate processing. The display unit 21 may be provided in a position where the user can check the displayed contents, and may be provided, for example, in the center of the top surface 23 of the ticket gate 1 or adjacent to the media processing unit 14.

As shown in FIG. 1, the height of the upper surface 23 from the floor surface is inclined so that it increases from the center of the ticket gate main body 10 toward the end on the exit side. The display unit 21 is placed on this inclined upper surface 23, making it easier for users to see the display unit 21.

The camera 16 is installed so as to ensure a shooting range that can capture the face of a user passing through the passage in the direction of travel. The camera 16 detects the face of the user when the user enters the ticket gate 1 and captures the face of the user. The ticket gate 1 then obtains facial image data from the captured image frame by face detection. The ticket gate 1 or the management server 30 that can communicate with the ticket gate 1 compares the acquired facial image data with registered facial image data that has been registered in advance. For example, the facial image data to be compared is a feature extracted from the image data. The ticket gate 1 or the management server 30 judges face authentication based on the similarity between the registered facial image data and the acquired facial image data, and judges whether the user is allowed to pass based on the judgment result. In this embodiment, an example of performing biometric authentication processing using facial image data as biometric information will be described, but the present invention is not limited to this. For example, biometric authentication processing may be performed using iris image data as biometric information.

The gate 24 is installed at the ticket gate 1 and physically blocks the user's passage if the user is not permitted to pass.

The management server 30 is connected to the ticket gate 1 by wire or wirelessly. The management server 30 is installed in the station premises or in a station control room. The management server 30 can also perform various authentications such as face recognition based on various information received from the ticket gate 1.

Next, the configuration of the ticket gate main body 10 according to the embodiment will be described.

Figure 2 is a block diagram showing an example of the configuration of the ticket gate 1 according to the embodiment.

As shown in FIG. 2, the ticket gate 1 includes a control unit 11 (first control unit), a memory unit 12 (first memory unit), a communication unit 13 (first communication unit), a detection unit 15, a camera 16, and a notification unit 25.

The control unit 11 controls various operations in the ticket gate 1. The control unit 11 has a processor that executes programs. For example, the control unit 11 is composed of a processor, memory, an interface, etc. The processor is, for example, a CPU (central processing unit), MPU (micro processing unit), SoC (system on a chip), DSP (digital signal processor), GPU (graphics processing unit), ASIC (application specific integrated circuit), PLD (programmable logic device), or FPGA (field-programmable gate array). Alternatively, the processor is a combination of these. The control unit 11 performs various processes by executing programs stored by the processor in the memory unit 12 or memory in the control unit 11.

The control unit 11 controls the passage of users. If both the authentication of the medium and the authentication of the user's face are successful, the control unit 11 allows the user to pass (enter or exit). On the other hand, if either the authentication of the medium or the authentication of the face fails, the control unit 11 controls the passage control mechanism to prevent the user from passing, prohibiting the user from passing. As a method of preventing passage, for example, the control unit 11 has a gate 24 and a drive mechanism that controls the opening and closing of the gate 24. The control unit 11 operates to close the gate 24 when preventing the user from passing (entering or exiting), and to open the gate 24 when allowing the user to pass.

The control unit 11 performs media determination to determine whether the information stored in media required to authenticate entry and exit at various gates, such as IC cards, QR codes, and bar codes, is correct.

The control unit 11 acquires face image data by face detection from an image frame captured by the camera 16. The control unit 11 compares the acquired face image data with registered face image data that has been registered in advance. The control unit 11 determines face authentication based on the similarity between the registered face image data and the acquired face image data, and outputs the determination result.

The ticket gate 1 (control unit 11) may perform the medium determination and face authentication determination, or instead of the ticket gate 1, the management server 30 that communicates with the ticket gate 1 may perform the medium determination and face authentication determination.

The storage unit 12 is configured with a rewritable non-volatile memory such as a hard disk drive (HDD) or a solid state drive (SSD). The storage unit 12 stores a user database. If the management server 30 performs the medium determination and face authentication determination instead of the ticket gate 1, the storage unit 12 does not need to store the user database. The user database will be explained in detail later.

The communication unit 13 is a communication interface for transmitting and receiving various data to and from the management server 30 via a wired or wireless connection. The communication unit 13 transmits and receives various information to and from the management server 30.

The detection unit 15 detects a user passing through a specified area on the ticket gate passage between the ticket gate main body 10 and the block body 18, and outputs a detection signal. For example, the detection unit 15 is composed of a general sensor that can detect people, such as an infrared sensor. The detection unit 15 is installed in a location that does not detect people who do not intend to pass through the ticket gate 1. For example, under the control of the control unit 11, the detection unit 15 detects a user in the passage where the ticket gate 1 is located. After the detection unit 15 detects a passerby, the detection unit 15 outputs detection information indicating that a user is passing through the ticket gate 1 under the control of the control unit 11. The camera 16 may then start taking pictures based on the detection information.

The notification unit 25 includes, for example, a display and a speaker. The display displays information. The display is provided in a position visible to a user who is passing through the ticket gate 1. For example, under the control of the control unit 11, the display displays information indicating whether or not a user is allowed to pass based on the facial authentication results. The information displayed on the display may be configured to be displayable on the display unit 21. The speaker outputs sound at a volume that can be recognized by the user. Under the control of the control unit 11, the speaker outputs sound such as an alert to a user who is determined not to be allowed to pass.

Figure 3 is a block diagram showing an example configuration of the management server 30 according to an embodiment.

As shown in FIG. 3, the management server 30 includes a control unit 31 (second control unit), a memory unit 32 (second memory unit), a communication unit 33 (second communication unit), and a display unit 34.

The control unit 31 controls various operations in the ticket gate 1. The control unit 31 has a processor that executes programs. For example, the control unit 31 is composed of a processor, memory, an interface, etc. The processor is, for example, a CPU, MPU, SoC, DSP, GPU, ASIC, PLD, or FPGA. Alternatively, the processor is a combination of these. The control unit 31 performs various processes by having the processor execute programs stored in the memory unit 32 or memory within the control unit 31.

For example, the control unit 31 controls the passage of a user by sending information that controls passage to the ticket gate 1. If both the authentication of the medium and the authentication of the user's face are successful, the control unit 31 sends information to the ticket gate 1 that allows the user to pass (enter or exit). On the other hand, if either the authentication of the medium or the authentication of the face fails, the control unit 31 sends information to the ticket gate 1 that denies the user passage. The control unit 11 of the ticket gate 1 that receives this information prevents the user from passing.

The control unit 31 can determine whether the information stored in the storage media required to authenticate entry and exit at various gates, such as IC cards, QR codes, and bar codes, is correct.

The control unit 31 acquires facial image data by face detection from the image frame captured by the camera 16. The control unit 31 compares the acquired facial image data with pre-registered registered facial image data. The control unit 31 determines facial authentication based on the similarity between the registered facial image data and the acquired facial image data, and outputs the determination result. In this manner, the management server 30 (control unit 31) may perform the facial authentication determination, or, instead of the management server 30, the ticket gate 1 communicating with the management server 30 may perform the facial authentication determination.

The storage unit 32 is configured with a rewritable non-volatile memory such as an HDD or SSD. The storage unit 32 stores a user database. The user database is as described above, and a detailed description will be omitted.

The communication unit 33 is a communication interface for transmitting and receiving various data to and from the ticket gate 1 via wired or wireless communication. The communication unit 33 transmits and receives various information to and from the ticket gate 1.

The display unit 34 is a display device that uses, for example, a liquid crystal display, an organic electroluminescence display, or the like, and displays voice, text, images, and the like under the control of the control unit 31. In other words, the display unit 34 is capable of displaying various types of information to the administrator who manages the management server 30.

FIG. 4 is a diagram showing an example of a user database stored in the ticket gate or the management server according to the embodiment.
The user database is data on all users who have been approved to use the ticket gate 1. The user database includes user information for each user. For example, the user information includes name, address, telephone number, medium identification information (hereinafter, medium ID), passage history (entrance and exit history), remaining amount data, and registered face image data. For example, a camera installed in station service equipment such as a ticket machine photographs a user, and the station service equipment obtains face image data from the captured image frame by face detection, and provides the obtained face image data as registered face image data.

Next, the operation of the ticket gate 1 and the management server 30 will be described. Here, a case will be described in which the management server 30 performs IC determination and facial authentication determination, but the ticket gate 1 may also perform IC determination and facial authentication determination. In that case, the IC determination and facial authentication determination performed by the control unit 31 of the management server 30 will be interpreted as being performed by the control unit 11 of the ticket gate 1.

FIG. 5 is a flowchart showing an example of the operation of the ticket gate according to the embodiment.
A user advances through the ticket gate passage from the entrance side in front of the ticket gate 1 to the exit side at the back as shown in Fig. 1. The camera 16 continuously captures images of a predetermined photographing area on the ticket gate passage (ST101), and the communication unit 13 transmits the photographed image data output from the camera 16 to the management server 30.

The detection unit 15 detects a specific user passing through a specific area on the ticket gate passage and outputs a detection signal. The control unit 11 starts continuous detection of the specific user based on the detection signal (ST102).

For example, when a specific user touches a first IC card to the media processing unit 14, the media processing unit 14 communicates with the first IC card that has entered its communication range and reads the first medium ID (first medium identification information) stored in the first IC card (ST103). The storage unit 12 stores an entry record including the first medium ID and entry date and time read by the media processing unit 14, or an exit record including the first medium ID and exit date and time. The communication unit 13 transmits a judgment request including the entry record or exit record to the management server 30.

The management server 30 receives the captured image data and the judgment request from the ticket gate 1, executes a first IC judgment and a first face authentication judgment based on the captured image data and the judgment request, and generates and transmits a first processing result related to the first IC judgment process and the first face authentication judgment process. The IC judgment and face authentication judgment by the management server 30 will be explained in detail later.

The communication unit 13 receives a first processing result related to the first IC determination process and the first face authentication determination process from the management server 30 (ST104).

Depending on the result of the first process, the control unit 11 instructs the IC card from which the first medium ID was read to write information (ST105). For example, if the result of the first IC determination process indicates a legitimate registrant and the result of the first face recognition determination process also indicates a legitimate registrant, i.e., if passage is permitted, the control unit 11 instructs the writing of passage information such as an entry history or exit history. The entry history includes the entry date and time, the ticket gate ID, etc. The exit history includes the exit date and time, the ticket gate ID, etc.

Based on the write instruction, the media processing unit 14 writes the write information to the IC card from which the first media ID was read (ST106), and if a write completion notification is received from the IC card within a specified time, the control unit 11 does not detect incomplete writing (ST107, NO), determines that the writing was successful (ST108), controls the opening and closing of the gate 24, and also controls the display content of the display unit 21 to allow passage (ST109).

If the control unit 11 does not receive a write completion notification from the IC card within a specified time, i.e., if it detects a reception error of the write completion notification, it detects that the writing is incomplete (ST107, YES), judges that there is an abnormality in the writing (ST110), controls the opening and closing of the gate 24, and also controls the display content of the display unit 21 to not allow passage (ST111).

The control unit 11 continues to detect the specified user based on the detection signal from the detection unit 15, i.e., when it detects that the specified user is lingering in the passage (ST112, YES), it accepts the retry process.

When the specified user touches the first IC card to the media processing unit 14 again during the retry processing acceptance period, the media processing unit 14 communicates with the first IC card that has entered the communication range and reads the first media ID stored in the first IC card (ST114).

If the first medium ID is read during the acceptance period for the retry process after the detection of incomplete writing, i.e., if the read first medium ID matches the first medium stored in the memory unit 12, the control unit 11 executes the retry process (ST115). In response to the retry process, the communication unit 13 transmits a retry determination request to the management server 30. The retry determination request includes the first medium ID read during the acceptance period for the retry process.

The management server 30 receives a retry judgment request from the ticket gate 1, performs a first IC judgment based on the retry judgment request, and transmits the first IC judgment result. The communication unit 13 receives the first IC judgment result from the management server 30 (ST116).

The control unit 11 instructs the IC card from which the first medium ID was read to write write information according to the third processing result regarding the first IC determination processing during execution of the retry processing (ST105). The media processing unit 14 writes the write information to the IC card from which the first medium ID was read based on the write instruction (ST106), and if a write completion notice is received from the IC card within a predetermined time, the control unit 11 does not detect incomplete writing (ST107, NO), determines that the writing was successful (ST108), controls the opening and closing of the gate 24, and also controls the display content of the display unit 21 to allow passage (ST109).

In addition, in the retry process, the first IC judgment in the management server 30 and reception of the first IC judgment result may be omitted, and an instruction to write write information may be issued to the IC card from which the first medium ID was read, provided that the read first medium ID matches the first medium stored in the memory unit 12.

In addition, if the second medium ID is read during the acceptance period for the retry process after the control unit 11 detects that writing has not been completed, that is, if the read second medium ID does not match the first medium stored in the memory unit 12, the communication unit 13 sends a determination request corresponding to the read second medium ID to the management server 30.

The management server 30 receives the captured image data from the ticket gate 1 and a judgment request corresponding to the second medium ID, performs a second IC judgment and a second facial recognition judgment based on the captured image data and the judgment request, and generates and transmits second processing results related to the second IC judgment process and the second facial recognition judgment process.

The communication unit 13 receives the second processing results related to the second IC determination process and the second face authentication determination process from the management server 30 (ST104). After that, the ticket gate 1 executes the processes from ST105 onwards.

In addition, if the control unit 11 does not continue to detect the specified user based on the detection signal from the detection unit 15, i.e., if the specified user is detected to have left the passage (ST112, NO), the retry process is not accepted, and the control unit 11 controls the opening and closing of the gate 24 and also controls the display content of the display unit 21 to allow the passage of a new user (ST113).

In addition, after the continuous detection period has elapsed, the control unit 11 can delete or overwrite the first medium ID stored in the memory unit 12, i.e., the first medium ID read during the continuous detection period.

FIG. 6 is a flowchart illustrating an example of the operation of the management server according to the embodiment.
When the communication unit 33 receives the captured image data and a judgment request from the ticket gate 1 (ST201, YES), the control unit 31 detects the first medium ID included in the judgment request and executes a first medium judgment process based on the first medium ID (ST202).

That is, the control unit 31 attempts to detect first user information including a first medium ID based on the user database in the storage unit 32. If the control unit 31 detects first user information including a first medium ID based on the user database in the storage unit 32 (ST203, YES), it generates and outputs a first processing result indicating proper registration (ST204); if the control unit 31 does not detect first user information including a first medium ID (ST203, NO), it generates and outputs a first processing result indicating non-registration (ST205).

The control unit 31 also executes a first face authentication process (first biometric authentication process) based on matching the first acquired face image data (first acquired biometric information) acquired in response to reading the first medium ID with the first registered face image data (first registered biometric information) registered in response to the first medium ID (ST206). Note that the first medium ID is information read during the continuous detection period, and the first acquired face image data is information acquired from face image data captured during the continuous detection period.

The received determination request includes an entry record or an exit record, the entry record includes a first medium ID and an entry date and time, and the exit record includes a first medium ID and an exit date and time. Thus, the entry date and time or the exit date and time corresponding to the first medium ID is identified. For example, the control unit 31 identifies captured image data for a corresponding time period based on the entry date and time or the exit date and time corresponding to the first medium ID, and identifies the first acquired face image data by face detection from the image frames constituting the identified captured image data.

The control unit 31 compares the first acquired face image data with the first registered face image data included in the first user information, and if the similarity between the first acquired face image data and the first registered face image data exceeds a reference value (ST207, YES), it generates and outputs a first processing result indicating regular registration (ST208), and if the similarity is equal to or less than the reference value (ST207, NO), it generates and outputs a first processing result indicating regular non-registration (ST208).
The communication unit 33 outputs the first processing result (ST209).

When the control unit 31 detects a second medium ID included in the determination request, it executes a second medium determination process based on the second medium ID, generates a second process result indicating proper registration or non-registration depending on whether the second user information including the second medium ID can be detected, and further executes a second face authentication process (second biometric authentication process) based on matching the second acquired face image data (second acquired biometric information) acquired in response to reading the second medium ID with the second registered face image data (second registered biometric information) registered in response to the second medium ID, and the communication unit 33 outputs the second processing result.

In addition, when the communication unit 33 receives a retry determination request from the ticket gate 1 (ST211, YES), the control unit 31 detects the first medium ID included in the retry determination request and executes a first medium determination process based on the first medium ID (ST212).

That is, the control unit 31 attempts to detect first user information including a first medium ID based on the user database in the storage unit 32. When the control unit 31 detects first user information including a first medium ID based on the user database in the storage unit 32 (ST213, YES), it outputs a third determination result indicating proper registration (ST214), and when the control unit 31 does not detect first user information including a first medium ID (ST213, NO), it outputs a third determination result indicating non-registration (ST215).
The communication unit 33 outputs the third determination result (ST216).

According to this embodiment, it is possible to provide a ticket gate, a ticket gate system, and a program that enable smooth retry processing. When writing is incomplete, the ticket gate system skips face recognition processing and executes writing processing, so that smooth ticket gate processing can be realized even in situations where appropriate face recognition judgment is difficult.

The program according to this embodiment may be transferred in a state stored in electronic devices such as the ticket gate 1 and the management server 30, or may be transferred in a state not stored in an electronic device. In the latter case, the program may be transferred via a network, or may be transferred in a state recorded on a recording medium. The recording medium is a non-transitory tangible medium. The recording medium is a computer-readable medium. The recording medium may be in any form, such as a CD-ROM or memory card, as long as it is capable of storing a program and is computer-readable.

Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention.
