Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an unauthorized boarding detection apparatus for detecting an unauthorized boarding in a railway vehicle.

  The railway company sells a commuter pass which can freely get on and off in a predetermined section (hereinafter also referred to as a commuter pass section) to passengers. Passengers may use the railway without paying an additional charge by presenting the commuter pass at the ticket gate at the boarding station in the commuter pass section and then presenting the commuter pass at the ticket gate at the get off station in the commuter pass section it can.

  In recent years, illegal riding using a commuter pass has become a problem. For example, after a passenger presents a commuter pass at a station in the commuter pass section and gets on it, he goes to a station outside the commuter pass section (first departure station or express stop station) and takes a turn around again. Get a commuter pass at and get off at. In this case, since the passenger does not pay the fare for boarding outside the commuter pass section, it is an illegal boarding. Since the passenger presents the commuter pass only at the boarding station and the getting-off station, the railway operator can not identify the passenger's halfway boarding route. Therefore, it was difficult to detect a passenger's illegal ride.

  Patent Document 1 describes a technology for specifying a passenger's boarding route by mounting a transceiver and a storage device on a commuter pass, and storing transit information of a station transmitted from a vehicle in the commuter pass. . According to such a technique, the railway company can identify the passenger's boarding route and charge the passenger for the fare outside the commuter pass section.

Japanese Patent Application Laid-Open No. 10-320594

  However, in the technology described in Patent Document 1, since it is necessary to mount the transceiver and the storage device on the commuter ticket, it becomes heavier than the conventional commuter ticket, and the burden on the passenger is large and inconvenient. In addition, when the station staff monitors the unauthorized boarding of the passengers without using the technology described in Patent Document 1, the burden on the station staff is large.

  The present invention has been made in view of the above-mentioned point, and an object of the present invention is to provide an unauthorized boarding detection device capable of detecting an unauthorized boarding of a passenger without putting a burden on the passengers and station staff.

  An unauthorized boarding detection device according to a first aspect of the present invention acquires a first image acquisition unit that acquires a first image of a passenger who presented a commuter pass of a railway, and a second image of the passenger in a station or a vehicle If the second image acquisition unit, the first image, and the second image captured in a station or a vehicle outside the section of the commuter ticket indicate the same passenger, an illegal ride is obtained. And an output unit that outputs information indicating that the boarding is determined to be an illegal ride determined by the determination unit.

  The determination unit records the number of times of determining that the passenger is the illegal ride for the passenger, and the output unit causes the illegal ride when the number of times recorded for the passenger is equal to or more than a predetermined value. You may output the information which shows that there exists.

  The determination unit determines whether or not the passenger is the illegal taker if the elapsed time from the time when the passenger entered at any one station to the time when he left the any station is longer than a predetermined time The determination of may be made.

  The determination unit uses the second image captured within a time range based on a required time between a station to which the passenger has entered and a particular station to determine whether the vehicle is an unauthorized rider or not. You may go.

  The said output part does not need to output the information which shows that it is the said irregular | improper boarding, when the said passenger leaves a station out of the area of the said commuter pass.

  The second image acquisition unit may acquire the second image obtained by imaging the passenger when getting in a vehicle or the passenger who is already in a vehicle.

  According to the present invention, it is possible to detect an illegal ride of a passenger without burdening the passengers and station staff.

[Description of illegal ride]
Fig.2 (a)-FIG.2 (c) are schematic diagrams for demonstrating the unjust boarding which the unfair boarding detection apparatus 1 which concerns on this embodiment detects. In FIG. 2 (a)-FIG.2 (c), the railway route by which the station C, the station A, and the station B are located in this order is illustrated by way of example. The passenger has a commuter pass of the section between the station A and the station B, but does not have a commuter pass of the section between the station C and the station A.

  In FIG. 2 (a), the passenger enters at station A, gets on the train in the direction of station B, and exits at station B. In this case, since the passenger only takes a ride in the commuter pass section, the unauthorized boarding detection device 1 does not detect an unauthorized boarding.

  In FIG. 2 (b), the passenger enters at station A, gets on the train in the direction of station C, and exits at station C. In this case, the passenger takes a ride from station A to station C which is outside the commuter pass section, but since the settlement of the shortage fare is performed at station C, the unauthorized ride detection device 1 does not detect an unauthorized ride .

  In FIG. 2 (c), passengers enter at station A and take a train in the direction of station C, then take a train in the direction of station B at station C and leave at station B. In this case, although the passenger is taking a train from Station A to Station C which is outside the commuter pass section, the fare for the section from Station A to Station C because Station B is within the commuter pass section Will not be settled. Therefore, the unauthorized boarding detection device 1 detects an unauthorized boarding (boarding outside the section).

  For example, when the station C is the starting station of a train, passengers may go out of the section as shown in FIG. 2 (c) for the purpose of getting on an available train. In addition, for example, when the station C is a stop station for express trains and the station A is not a stop station for express trains, the passengers take an outside trip as shown in FIG. 2 (c) for the purpose of getting on the express trains. Sometimes. Conventionally, since the railway company could not identify the passenger's boarding route, it could not collect fares pertaining to off-zone boarding from the passengers. In addition, unfairness occurs between a passenger who purchases a commuter pass from Station C to Station B and gets on a legal ride, and a passenger who purchases a commuter pass from Station A to Station B and gets off the section It was

  The unauthorized boarding detection device 1 can make it possible to collect appropriate fares and correct unfairness among the passengers by identifying the passengers who took the off-section and notifying the station staff.

[Configuration of unauthorized boarding detection system S]
FIG. 3 is a block diagram of the unauthorized boarding detection system S according to the present embodiment. In FIG. 3, arrows indicate the flow of main data, and there may be flows of data other than those shown in FIG.

  The communication unit 12 is a communication interface for communicating with the first camera 21, the second camera 22, the entry ticket gate 31, the exit ticket gate 32 and the station terminal 4 via the network N. The communication unit 12 performs predetermined processing on the communication signals received from the first camera 21, the second camera 22, the entry ticket gate 31, the exit ticket gate 32 and the station terminal 4 to obtain data, and the obtained data is sent to the control unit 11. Enter in Further, the communication unit 12 performs predetermined processing on the data input from the control unit 11 to generate a communication signal, and the generated communication signal is generated by the first camera 21, the second camera 22, the entrance ticket 31, and the exit ticket 32. And transmit to the station terminal 4.

  The storage unit 13 is a storage medium including a read only memory (ROM), a random access memory (RAM), a hard disk drive, and the like. The storage unit 13 stores in advance a program to be executed by the control unit 11.

  The control unit 11 is a processor such as a central processing unit (CPU), for example, and executes the program stored in the storage unit 13 to obtain an information acquisition unit 111, a first image acquisition unit 112, and a second image acquisition unit 113. Functions as the determination unit 114 and the output unit 115. At least a part of the functions of the control unit 11 may be performed by an electric circuit. In addition, at least a part of the functions of the control unit 11 may be executed by a program executed via a network.

  The unauthorized riding detection device 1 according to the present embodiment is not limited to the specific configuration shown in FIG. The unauthorized boarding detection device 1 is not limited to one device, and may be configured by connecting two or more physically separated devices in a wired or wireless manner.

  The information acquisition unit 111 identifies the station where the entrance ticket 31 and exit ticket 32 are installed from the entrance ticket 31 and exit ticket 32 together with the information read by the entrance ticket 31 and exit ticket 32 from the passenger's card. It is acquired and stored in the storage unit 13. The information read from the passenger's card includes card information identifying the card, and commuter pass section information indicating a commuter pass section.

  The first image acquisition unit 112 acquires an image (referred to as a first image) captured by the first camera 21 from the first camera 21, and stores the acquired image in the storage unit 13 in association with the information acquired by the information acquisition unit 111. Furthermore, the first image acquisition unit 112 extracts information (referred to as first characteristic information) indicating features such as a human face and clothes from the first image, and card information for identifying the passenger acquired by the information acquisition unit 111. And in the storage unit 13 in association with each other. The second image acquisition unit 113 acquires an image (referred to as a second image) captured by the second camera 22 from the second camera 22 and causes the storage unit 13 to store the image. Further, the second image acquisition unit 113 extracts information (referred to as second feature information) indicating features such as a human face and clothes from the second image, and stores the information in the storage unit 13. The first feature information and the second feature information may be image data representing an image of a passenger's face, clothes, and the like, and may be information (feature amount) obtained by digitizing features such as the face and clothes.

  The first feature information and the second feature information are used to determine the identity of a person by the determination unit 114 comparing them. Known image recognition techniques can be used to determine the identity of a person from an image. As the first feature information and the second feature information, any value used by the image recognition technology can be used, for example, a value indicating the distribution of luminance in each area in the first image and the second image can be used it can.

  The unauthorized boarding detection device 1 may determine the identity between the passenger indicated by the first image and the passenger indicated by the second image by directly comparing the first image and the second image. In this case, the first image acquisition unit 112 and the second image acquisition unit 113 do not extract and store the first feature information and the second feature information.

  In addition, the second image acquisition unit 113 causes the storage unit 13 to store information indicating a station (that is, a boarding station) at which the second image is captured in association with the second image. When the second camera 22 is provided in a vehicle, the second image acquisition unit 113 receives, from the vehicle, information indicating a station at which the vehicle is currently stopped, and identifies the station at which the second image is captured. When the second camera 22 is provided at the station, the second image acquisition unit 113 captures the second image from the second camera 22 installed station database stored in the storage unit 13 in advance. Identify the station where you

  The first image acquisition unit 112 reads the first image or the first feature information stored in advance in the storage unit 13 instead of acquiring the first image captured by the first camera 21 to obtain the first image or the first image or the first feature information. The first feature information may be acquired. In this case, the first image is captured by an imaging device installed at a position where the face of the passenger can be captured at a predetermined timing, for example, when the passenger purchases a commuter pass. In the storage unit 13, the first image captured at a predetermined timing or the first feature information extracted from the first image is stored in advance in association with the card information of the passenger. Then, the first image acquisition unit 112 acquires the first image or the first feature information associated with the card information read by the entry ticket gate 31.

  With such a configuration, it is not necessary to provide the first camera 21 in the entry ticket gate 31. In addition, since the first image and the first feature information are not acquired at the time of entrance of a passenger, it is possible to reduce the load on the unauthorized boarding detection device 1 particularly in the time zone in which the passengers are concentrated.

  The determination unit 114 collates the second feature information extracted from the second image with each of the first feature information stored in the storage unit 13. When the first feature information and the second feature information are similar (specifically, the similarity calculated from the first feature information and the second feature information is equal to or more than a predetermined value), the determination unit 114 Determines that the passenger indicated by the first feature information is identical to the passenger indicated by the second feature information, and associates the first feature information with the second feature information. In other words, the determination unit 114 determines that the passenger shown in the first image is also shown in the second image.

  When the determination unit 114 determines that the passenger indicated by the first feature information and the passenger indicated by the second feature information are identical, the boarding station where the second image in which the passenger is imaged is the passenger It is determined whether or not it is included in a section other than the commutation ticket section recorded on the card of. Then, the determination unit 114 determines that the boarding station is out of the section when the boarding station is included in a section other than the commuter ticket section, and determines that the boarding is not outside the section (that is, it is a legitimate boarding) otherwise. The determination unit 114 causes the storage unit 13 to store the result of the determination.

  The output unit 115 outputs the result determined by the determination unit 114 by a predetermined method. For example, the output unit 115 identifies information indicating that the passenger has taken the out-of-section and the passenger when the passenger determined to have taken the out-of-section by the determination unit 114 passes the exit ticket gate 32 The station terminal 4 is notified of the information to be For example, the output unit 115 causes the display of the station terminal 4 to display an image of the face of the passenger (that is, at least one of the first image and the second image) as information for identifying the passenger. Further, the output unit 115 outputs information indicating that the vehicle is traveling outside the section to the exit ticket gate 32, and the exit ticket gate 32 closes the opening / closing body when the information is received.

  Here, when the passenger leaves the commuter ticket section, the output unit 115 does not output the determination result even if the determination unit 114 determines that the passenger has traveled outside the section. This is because when the passenger leaves the commuter pass section, the shortage fare is settled as shown in FIG.

  Further, the output unit 115 outputs a result determined by the determination unit 114 by any method such as storing in a storage device, outputting sound from a speaker, lighting a lamp, printing from a printer, etc. It is also good.

In addition, the first image acquisition unit 112 causes the storage unit 13 to store, as the entry time information D, the first image obtained by capturing the passenger by the first camera 21 and the first feature information extracted from the first image. The out-of-section boarding flag is set to a value indicating that it is not an out-of-section boarding as an initial value, and is set to a value indicating that it is an out-of-section boarding when the determination unit 114 determines out-of-section boarding.

  FIG. 4 (b) represents the on-board information E stored when the passenger gets on the vehicle (ie, on board). The boarding time information E includes boarding station information indicating a boarding station, a second image acquired from the second camera 22, and second feature information extracted from the second image. The second image acquisition unit 113 takes the second image taken by the second camera 22 and the second feature information extracted from the second image together with the boarding station information identifying the station at which the second image was taken, It is stored in the storage unit 13 as information E.

  FIG. 4C shows exit time information F stored when the passenger passes through the exit ticket gate 32 (i.e., at the time of exit). The exit information F includes card information for identifying a card and exit station information for identifying an exit station. The information acquisition unit 111 stores the card information read by the exit ticket 32 from the passenger's card in the storage unit 13 as exit time information F together with exit station information identifying the station where the exit ticket 32 is installed. When the same card is presented by the passenger in the entry ticket gate 31 and the exit ticket ticket 32, the card information of the exit information F matches the card information of the entry information D.

  The data recorded as the entry time information D, the boarding information E, and the exit time information F may be recorded in any format, and may be, for example, character string data, numerical data, or binary data. The entry time information D, the boarding time information E, and the exit time information F may be recorded as a database, or may be recorded as a list listing data.

And the exit station information which identifies the station in which this exit ticket gate 32 is installed is acquired (S32). The information acquiring unit 111 associates the card information and the exit station information acquired in step S32, and stores them in the storage unit 13 as exit time information F (S33).

  The output unit 115 acquires from the storage unit 13 the out-of-section boarding flag included in the entry time information D associated with the card information acquired in step S32 (S34). When the out-of-section boarding flag acquired in step S34 indicates that the boarding is out-of-section (YES in S35), the output unit 115 outputs information indicating the out-of-section boarding to the exit ticket 32, and The information indicating that the passenger has taken the out of the section and the information specifying the passenger are notified to S4 (S36). The exit ticket 32 closes the opening and closing body by receiving information indicating that the vehicle is traveling outside the section.

  When the out-of-section boarding flag acquired in step S34 indicates that the out-of-section boarding is not performed (NO in S35), the output unit 115 outputs information indicating that the out-of-section boarding is not performed to the exit ticket 32, and the exit ticket 32 The open / close body is opened by receiving the information indicating that the vehicle is not out of the section (S37).

  If a predetermined termination condition (for example, that a station staff performs a predetermined termination operation on the unauthorized boarding detection apparatus 1) is not satisfied (NO in S38), the unauthorized boarding detection apparatus 1 returns to step S31 and repeats the process. If the predetermined termination condition is satisfied (YES in S38), the unauthorized riding detection device 1 terminates the process.

First Modification of First Embodiment
In the above embodiment, closing of the ticket gate and notification to the station clerk are performed when outboard travel is detected even once, but closing of the ticket gate and station clerk according to the total number of times outboard passenger travel is detected for one passenger May be notified. When the determination unit 114 determines that a passenger is boarding out of a section (S28 in FIG. 6), the number of times boarding out of a section is detected in association with the card information of the passenger in the storage unit 13 (initial value is zero Raise).

  When the number of times of recording for one passenger exceeds a predetermined value, the output unit 115 closes the ticket gate and notifies the station clerk (S36 in FIG. 7). With such a configuration, when the unauthorized boarding detection device 1 detects a passenger who repeatedly rides outside the section, it can close the ticket gate and notify the station staff, so there is an error in one determination. In addition, it is possible to prevent a passenger from being mistakenly identified as having taken an illegal ride.

  The output unit 115 may determine the number of times until the closing of the ticket gate and the notification to the station clerk are performed based on the certainty of the determination in the determination unit 114. For example, the output unit 115 reduces the number of times as the degree of similarity between the first feature information and the second feature information increases. By doing this, the station staff can alert the passengers in a short period of time when the first image and the second image clearly show a passenger who got on an illegal ride.

Second Modification of First Embodiment
Although the above-described embodiment assumes that the passenger who gets off the section in FIG. 2 (c) gets off the train at station C and then gets on the train again, especially when the train turns around at station C. There is a case to continue riding without getting off at the station C.

  Therefore, the second camera 22 may be configured not only to capture an area including the face of the passenger when getting on the vehicle, but also to capture an area including the face of the passenger who is already getting on the vehicle. . In this case, the second camera 22 captures a passenger in the vehicle at a predetermined timing (e.g., a timing before the passenger from the boarding station starts to board the vehicle) and acquires a second image.

  Then, the unauthorized boarding detection device 1 determines the boarding out of the section by using the boarding time information E including the second image of the passenger who gets in the vehicle or the passenger who is already in the vehicle. With such a configuration, it is possible to detect boarding outside the section even when passengers continue riding without getting off at a station where turnaround operation is performed.

[Effect of First Embodiment]
The unauthorized boarding detection system S according to the present embodiment can detect a passenger's outside boarding by imaging a face of a passenger using a camera provided in a station or a vehicle. Therefore, there is no need for the station staff to monitor the passenger's outboarding of the section, and the burden on the station staff can be reduced. In addition, since the unauthorized boarding detection system S can use a conventional IC card or magnetic card, it does not burden the passengers.

  Furthermore, by identifying the passenger who took the off-section by the unauthorized boarding detection device 1 and notifying the station staff, it is possible to make it possible to collect appropriate fares and correct the inequity between the passengers. In addition, it is possible to ease congestion due to concentration of passengers outside the section at a specific station such as a starting station or an express stopping station.

Second Embodiment
While the first embodiment makes the determination for getting out of the section at the timing when the passenger gets on the vehicle (that is, when getting in), the present embodiment makes the section at the timing when the passenger passes the exit ticket (that is, at the time of leaving) Determine the outside of the hotel. As a result, the determination can be performed even when the passenger leaves the vehicle, and the other configurations and processes that can increase the degree of freedom in the implementation of the unauthorized boarding detection method are the same as those in the first embodiment.

[Flowchart of on-board processing]
FIG. 8 is a diagram showing a flowchart of the on-board process of the unauthorized boarding detection method according to this embodiment. In the flowchart of FIG. 8, steps S26 to S28 of the flowchart of FIG. 6 are omitted. That is, after storing the on-board information E in the storage unit 13 in steps S21 to S25, the unauthorized boarding detection device 1 repeats or ends the process according to the condition of step S29.

[Flowchart of exit processing]
FIG. 9 is a diagram showing a flowchart of exit processing of the unauthorized boarding detection method according to the present embodiment. The flowchart of FIG. 9 represents processing in the case where the station where the exit ticket gate 32 through which the passenger has passed is installed is within the section of the passenger's commuter pass. If the station where the exit ticket gate 32 through which the passenger has passed is installed is outside the section of the passenger's commuter pass ticket, the shortage fare is settled by a process not shown. In the flowchart of FIG. 9, step S34 of the flowchart of FIG. 7 is omitted, and instead, steps S39 to S40 are performed after step S33 and before step S35.

  First, the unauthorized boarding detection device 1 stores the leaving time information F in the storage unit 13 in steps S31 to S33. Next, the determination unit 114 specifies the entry time information D from the card information acquired in step S32, and obtains the first feature information included in the entry time information D (S39).

  The determination unit 114 collates the first feature information acquired in step S39 with each of the second feature information stored in the storage unit 13. When the first feature information and the second feature information are similar, the determination unit 114 determines that the passenger indicated by the first feature information is identical to the passenger indicated by the second feature information. The first feature information is associated with the second feature information. Then, the determination unit 114 specifies the on-board information E including the second feature information associated with the first feature information acquired in step S39 (S40).

  When the boarding station of the boarding time information E identified in step S40 is outside the commuter pass section of the entrance time information D identified in step S39, the determination unit 114 determines that the boarding is out of the zone. If the boarding station of the boarding information E identified in step S40 is within the commuter pass section of the entrance information D identified in step S39, the determination unit 114 does not determine that the boarding is out of the section.

  Then, the unauthorized boarding detection device 1 performs steps S35 to S38 based on the determination result of the out-of-zone boarding by the determination unit 114.

[Effect of Second Embodiment]
The unauthorized boarding detection apparatus 1 according to the present embodiment can achieve the same effect as that of the first embodiment, and can determine the out-of-zone boarding at the timing of the exit of a passenger different from that of the first embodiment. Therefore, it is possible to improve the degree of freedom in implementing the unauthorized boarding detection method. In addition, the present embodiment may be combined with the first embodiment, and the determination of the outside of the section may be performed both when the passenger gets on the vehicle and when the passenger leaves the station.

Third Embodiment
In the present embodiment, it is possible to selectively determine that the passenger has traveled outside the zone for a passenger whose time from entry time to exit time is longer than normal, and the second image (second feature information based on the required time between stations) ) Is selected to perform comparison with the first image (first feature information). As a result, it is possible to reduce the amount of the determination target of out-of-zone boarding, and therefore the load on the unauthorized boarding detection device 1 can be reduced. The other configurations and processes are similar to those of the second embodiment.

[Selection of passengers and images to be judged]
In the present embodiment, the unauthorized boarding detection device 1 further records the entrance time (that is, the time when the passenger passes the entrance ticket gate 31) in the entrance time information D of FIG. 4A, and the boarding time of FIG. The boarding time (that is, the time when the passenger got on the vehicle) is further recorded in the information E, and the leaving time (that is, the time when the passenger passed the exit ticket 32) is further recorded in the leaving time information F of FIG. The entrance time may be the time when the first image was captured, and the boarding time may be the time when the second image was captured.

  First, there is a possibility that a passenger who has a long elapsed time from the entrance station to the exit station may be out of the section as shown in FIG. 2 (c). Therefore, the determination unit 114 selects only the entry time information D in which the elapsed time from the entrance time to the exit time is longer than a predetermined time, and determines that the user is out of the section. The predetermined time used as the determination reference of the elapsed time is a value obtained by adding a predetermined suspension (for example, 10 minutes) to the required time from the entrance station to the exit station (that is, the time it normally takes). As a result, it is possible to set only the passengers who may be taking an out-of-zone ride as the target of the out-of-zone taking.

  Secondly, the boarding station (station C in FIG. 2 (c)) at which passengers who board outside the section get on and off is often a specific station such as a starting station of a train or a stopping station of a express train. Since the time required between stations is substantially constant, in order to track the passengers of the first image imaged at the entrance station, the first image taken at the boarding station before and after the entrance time has elapsed. It is sufficient if only two images are to be compared.

  Therefore, when the determination unit 114 collates the first feature information of the first image captured at entry with the second feature information of the second image captured at entry, the elapsed time from the entry time to the entry time is Only the second feature information of the second image within a predetermined time range is selected to be matched. The predetermined time range used as the judgment standard of the elapsed time is a predetermined time range based on the required time from the entrance station to a specific station such as the first train station or the express stop station (for example, a predetermined grace period is provided before and after the required time) Time range). If there are multiple specific stations, multiple time ranges may be set. As a result, it is possible to set only the image having the possibility of capturing the passenger taking the out-of-zone boarding as the target of the determination of the out-of-zone boarding.

  Further, the determination unit 114 may set the predetermined time range used as the determination reference of the elapsed time to a different value depending on the time zone. For example, the determination unit 114 makes the time range in the daytime time zone where the number of trains is small longer than the time range in the commuting time zone. By doing this, the determination unit 114 can make the determination based on the required time that differs for each time zone, so that the determination accuracy can be improved.

[Flowchart of exit processing]
FIG. 10 is a diagram showing a flowchart of exit processing of the unauthorized boarding detection method according to the present embodiment. The flowchart in FIG. 10 shows processing in the case where the station where the exit ticket gate 32 through which the passenger has passed is installed is within the section of the passenger's commuter pass. If the station where the exit ticket gate 32 through which the passenger has passed is installed is outside the section of the passenger's commuter pass ticket, the shortage fare is settled by a process not shown. In the flowchart of FIG. 10, step S41 is performed after step S33 of the flowchart of FIG. 9 and before step S39, and step S42 is performed after step S39 and before step S40.

  First, the unauthorized boarding detection device 1 stores the leaving time information F in the storage unit 13 in steps S31 to S33. Next, the determination unit 114 acquires the entrance time included in the entrance time information D specified from the card information acquired in step S32. In addition, the determination unit 114 obtains the leaving time from the information at the time of leaving obtained in step S32. When the elapsed time from the entrance time to the exit time is equal to or less than the predetermined time (NO in S41), the output unit 115 outputs information indicating that the passenger is not out of the section to the exit ticket 32, and the exit ticket 32 The opening and closing body is opened by receiving the information indicating that the user is not traveling outside (S37).

  If the elapsed time from the entrance time to the exit time is longer than the predetermined time (YES in S41), the determination unit 114 identifies the entry time information D from the card information acquired in step S32, and the entry time information The first feature information included in D is acquired (S39).

  The determination unit 114 acquires the entrance time included in the entrance time information D specified from the card information acquired in step S32, and acquires the boarding time from each boarding time information E stored in the storage unit 13, The elapsed time from the entrance time to the boarding time is calculated. Then, the determination unit 114 selects the second image of the on-board information E within a predetermined time range based on the required time from the entrance station to the specific station (S42).

  The determination unit 114 collates the first feature information acquired in step S39 with each of the second feature information of the second image selected in step S42. When the first feature information and the second feature information are similar, the determination unit 114 determines that the passenger indicated by the first feature information is identical to the passenger indicated by the second feature information. The first feature information is associated with the second feature information. Then, the determination unit 114 specifies the on-board information E including the second feature information associated with the first feature information acquired in step S39 (S40).

  When the boarding station of the boarding time information E identified in step S40 is outside the commuter pass section of the entrance time information D identified in step S39, the determination unit 114 determines that the boarding is out of the zone. If the boarding station of the boarding information E identified in step S40 is within the commuter pass section of the entrance information D identified in step S39, the determination unit 114 does not determine that the boarding is out of the section. Then, the unauthorized boarding detection device 1 performs steps S35 to S38 based on the determination result of the out-of-zone boarding by the determination unit 114.

[Effect of the third embodiment]
In addition to the same effects as in the first embodiment, the unauthorized boarding detection device 1 according to the present embodiment narrows down the passengers and images to be determined as the out-of-zone boarding based on time. As a result, it is possible to reduce the amount of the determination target of out-of-zone boarding, and therefore the load on the unauthorized boarding detection device 1 can be reduced.
