MODE FOR CARRYING OUT THE INVENTION

[0009] Hereinafter, embodiments of the admission management system, the admission management method, and the recording medium will be described with reference to the drawings.

[0010] (1) First Embodiment First, a first embodiment of the admission management system, the admission management method, and the recording medium will be described. Hereinafter, with reference to FIG. 1, a first embodiment of the admission management system, the admission management method, and the recording medium will be described using the admission management system 1000 to which the first embodiment is applied. FIG. 1 is a block diagram showing the configuration of the admission management system 1000 in the first embodiment.

[0011] The entrance management system 1000 manages the entrance of target persons riding in a target vehicle into an entrance restricted area. To manage the entrance of target persons into the entrance restricted area, the entrance management system 1000 includes a storage unit 1100, a first imaging unit 1200, a first determination unit 1300, a second imaging unit 1400, a second determination unit 1500, and an entrance management unit 1600.

[0012] The storage unit 1100 stores registration information 1110. The registration information 1110 is information in which vehicle information 1111 and person information 1112 are associated. The vehicle information 1111 indicates the license plate number of a registered vehicle scheduled to enter the entrance restricted area. The person information 1112 includes a registered image of a registered person scheduled to enter the entrance restricted area while riding in the registered vehicle.

[0013] The first imaging unit 1200 generates a vehicle image by imaging a target vehicle located at a vehicle entrance through which the target vehicle should pass to enter the entrance restricted area. The first determination unit 1300 determines whether the target vehicle located at the vehicle entrance is a registered vehicle by comparing the license plate number of the target vehicle captured in the vehicle image with the license plate number of the registered vehicle indicated by the vehicle information.

[0014] The second imaging unit 1400 generates a person image by imaging a target person riding in the target vehicle located at the vehicle entrance. The second determination unit 1500 determines whether the target person riding in the target vehicle is a registered person by comparing the person image with the registered image indicated by the person information.

[0015] The entrance control unit 1600 permits the vehicle to pass through the vehicle entrance if the first determination unit 1300 determines that the vehicle located at the vehicle entrance is a registered vehicle, and the second determination unit 1500 determines that the person riding in the vehicle is a registered person. On the other hand, the entrance control unit 1600 does not permit the vehicle to pass through the vehicle entrance if the first determination unit 1300 determines that the vehicle located at the vehicle entrance is not a registered vehicle. Furthermore, the entrance control unit 1600 does not permit the vehicle to pass through the vehicle entrance if the second determination unit 1500 determines that the person riding in the vehicle is not a registered person.

[0016] The entry management system 1000 described above determines whether or not to allow a vehicle to pass through the vehicle entrance using the vehicle image captured by the first imaging unit 1200, the person image captured by the second imaging unit 1400, and the registration information pre-stored in the storage unit 1100. Therefore, in order for a person to enter the restricted entry area, it is no longer necessary for the person to get out of their vehicle at the vehicle entrance and fill out necessary information on paper. As a result, the person can enter the restricted entry area while remaining in their vehicle. Consequently, the time required to enter the restricted entry area is shortened. As a result, the possibility of a large number of vehicles wishing to enter the restricted entry area accumulating at the vehicle entrance (resulting in congestion) is reduced. Therefore, the entry management system 1000 can solve the technical problem of a large number of vehicles wishing to enter the restricted entry area potentially accumulating at the vehicle entrance.

[0017] Furthermore, the entry management system 1000 permits the vehicle to pass through the vehicle entrance only if it is determined that the vehicle is a registered vehicle and the person in question is a registered person. Therefore, compared to a system where the vehicle is permitted to pass through the vehicle entrance even when the vehicle is determined to be a registered vehicle but the person in question is not, the entry management system 1000 can more effectively prevent suspicious individuals from entering the restricted entry area. Similarly, compared to a system where the vehicle is permitted to pass through the vehicle entrance even when the person in question is determined to be a registered person but the vehicle is not, the entry management system 1000 can more effectively prevent suspicious individuals from entering the restricted entry area. Therefore, the entry management system 1000 can solve the technical problem of the possibility of suspicious individuals entering the restricted entry area.

[0018] (2) Second Embodiment Next, a second embodiment of the admission management system, admission management method, and recording medium will be described. In the following, the second embodiment of the admission management system, admission management method, and recording medium will be described using the admission management system SYS to which the second embodiment of the admission management system, admission management method, and recording medium is applied.

[0019] The entry management system SYS manages the entry of person P into the restricted entry area 9 by riding in the target vehicle V. Furthermore, the entry management system SYS may monitor the actions of person P within the restricted entry area 9 once they have entered. Furthermore, the entry management system SYS may manage the exit of person P from the restricted entry area 9 once they have entered.

[0020] In the second embodiment, an example is described in which the restricted entry area 9 is a factory. In this case, the entry management system SYS may manage the entry of person P into the factory by riding in a target vehicle V. Furthermore, the entry management system SYS may manage the actions of person P within the factory after they have entered. Furthermore, the entry management system SYS may manage the departure of person P from the factory after they have entered.

[0021] However, restricted access area 9 is not limited to factories. Restricted access area 9 can be any area in which the free entry of the person concerned is restricted. For example, other examples of restricted access area 9 include corporate offices, schools, theme parks, and airports.

[0022] The following is a description of the SYS access control system.

[0023] (2-1) Configuration of the SYS access control system First, the configuration of the access control system SYS in the second embodiment will be described.

[0024] (2-1-1) Overall configuration of the SYS entry management system First, the overall configuration of the access control system SYS in the second embodiment will be described with reference to Figures 2 and 3. Figure 2 is a block diagram showing the overall configuration of the access control system SYS in the second embodiment. Figure 3 is a layout diagram of the access restriction area 9 into which the target person P enters.

[0025] As shown in Figures 2 and 3, the entry management system SYS comprises a vehicle gate device 1, a user terminal 2, a person gate device 3, a surveillance camera 4 which is a specific example of the "fourth imaging means" described in the appendix below, and an entry management server 5. In the example shown in Figure 2, the entry management system SYS has multiple user terminals 2, but it may also have a single user terminal 2. Furthermore, in the example shown in Figure 2, the entry management system SYS has multiple surveillance cameras 4, but it may also have a single surveillance camera 4.

[0026] As shown in Figure 3, the vehicle gate device 1 is positioned at the vehicle entrance 91 through which the target vehicle V must pass in order to enter the restricted entry area 9. The target vehicle V enters the restricted entry area 9 (particularly the first restricted area 9A within the restricted entry area 9) from an area outside the restricted entry area 9 via the vehicle entrance 91. The vehicle gate device 1 generates a vehicle image IMG_V containing the target vehicle V by capturing an image of the target vehicle V located at the vehicle entrance 91 in order to enter the restricted entry area 9. The vehicle gate device 1 transmits the generated vehicle image IMG_V to the entry management server 5.

[0027] The vehicle entrance 91 may be used as a vehicle exit through which the target vehicle V should pass in order to exit the restricted entry area 9. The target vehicle V may exit the restricted entry area 9 to an area outside the restricted entry area 9 via the vehicle entrance 91. The vehicle gate device 1 may generate a vehicle image IMG_V in which the target vehicle V is captured by imaging the target vehicle V located at the vehicle entrance 91 in order to exit the restricted entry area 9.

[0028] However, the vehicle entrance 91 does not have to be used as a vehicle exit through which the target vehicle V must pass in order to exit the restricted entry area 9. The restricted entry area 9 may have a separate vehicle exit through which the target vehicle V must pass in order to exit the restricted entry area 9, in addition to the vehicle entrance 91. In this case, the vehicle gate device 1 described above may be placed at the vehicle exit. In the following explanation, we will describe an example in which the vehicle entrance 91 is used as a vehicle exit through which the target vehicle V must pass in order to exit the restricted entry area 9.

[0029] User terminal 2 is an information terminal (e.g., a smartphone or tablet) owned by the person P entering the restricted entry area 9. Therefore, the entry management system SYS may have the same number of user terminals 2 as the number of person P entering the restricted entry area 9. However, one user terminal 2 may be shared by two or more person P. User terminal 2 generates a person image IMG_P1 containing person P by capturing an image of person P riding in a target vehicle V located at the vehicle entrance 91. For example, user terminal 2 may generate a person image IMG_P1 by capturing an image of person P riding in a target vehicle V that is about to enter the restricted entry area 9 via the vehicle entrance 91. For example, user terminal 2 may generate a person image IMG_P1 by capturing an image of person P riding in a target vehicle V that is about to leave the restricted entry area 9 via the vehicle entrance 91. User terminal 2 transmits the generated person image IMG_P1 to the entry management server 5.

[0030] As shown in Figure 3, the person gate device 3 is positioned at the person entrance 92 within the restricted entry area 9. The target vehicle V, having passed through the vehicle entrance 91, is parked in the parking lot 93 within the restricted entry area 9 (particularly within the first restricted area 9A). The target person P exits the vehicle V and then passes through the person entrance 92. The target person P enters the second restricted area 9B within the restricted entry area 9 from the first restricted area 9A within the restricted entry area 9 via the person entrance 92. In this case, the person entrance 92 may be considered as the person entrance that the target person P must pass through in order to enter the second restricted area 9B. The person gate device 3 generates a person image IMG_P2 containing the target person P by capturing an image of the target person P located at the person entrance 92 in order to enter the second restricted area 9B. The person gate device 3 transmits the generated person image IMG_P2 to the entry management server 5.

[0031] Person entrance 92 may also be used as a person exit entrance through which person P should pass in order to exit the second restricted area 9B. Person P may exit from the second restricted area 9B to the first restricted area 9A via person entrance 92. Person gate device 3 may generate a person image IMG_P2 in which person P is captured by imaging person P located at person entrance 92 in order to exit the second restricted area 9B.

[0032] However, the person entrance 92 does not have to be used as a person exit that the person P must pass through to exit the second restricted area 9B. A person exit that the person P must pass through to exit the second restricted area 9B may be provided separately from the person entrance 92 in the restricted entrance area 9. In this case, the person exit may be provided with the person gate device 3 described above. In the following explanation, we will describe an example in which the person entrance 92 is used as a person exit that the person P must pass through to exit the second restricted area 9B.

[0033] The surveillance camera 4 is positioned within the restricted entry area 9. In the example shown in Figure 3, each of the multiple surveillance cameras 4 is positioned in the second restricted area 9B within the restricted entry area 9 (i.e., the area into which the target person P enters after passing through the person entrance 92). However, at least one of the multiple surveillance cameras 4 may be positioned in the first restricted area 9A within the restricted entry area 9 (i.e., the area into which the target person P enters after passing through the vehicle entrance 91 but not yet passing through the person entrance 92). The surveillance camera 4 captures its imaging range 41, thereby generating a surveillance image IMG_M that captures the scene within the imaging range 41. The surveillance camera 4 transmits the generated surveillance image IMG_M to the access control server 5.

[0034] The entry management server 5 performs vehicle entry management operations to manage the entry of the target vehicle V into the restricted entry area 9 (particularly the first restricted area 9A) via the vehicle entrance gate 91. To perform vehicle entry management operations, the entry management server 5 obtains a vehicle image IMG_V from the vehicle gate device 1 and a person image IMG_P1 from the user terminal 2. Based on the vehicle image IMG_V, the entry management server 5 determines whether the target vehicle V located at the vehicle entrance gate 91 is a registered vehicle V_R scheduled to enter the restricted entry area 9. Furthermore, based on the person image IMG_P1, the entry management server 5 determines whether the target person P riding in the target vehicle V is a registered person P_R scheduled to enter the restricted entry area 9. If the target vehicle V is determined to be a registered vehicle V_R and the target person P is determined to be a registered person P_R, the entry management server 5 permits the target vehicle V to pass through the vehicle entrance gate 91. In other words, the entry management server 5 permits the target vehicle V and the target person P riding in the target vehicle V to enter the restricted entry area 9 (especially the first restricted area 9A) via the vehicle entrance 91. On the other hand, if the target vehicle V is determined not to be the registered vehicle V_R, the entry management server 5 does not permit the target vehicle V to pass through the vehicle entrance 91. Also, if the target person P is determined not to be the registered person P_R, the entry management server 5 does not permit the target vehicle V to pass through the vehicle entrance 91. In other words, the entry management server 5 does not permit the target vehicle V and the target person P riding in the target vehicle V to enter the restricted entry area 9 (especially the first restricted area 9A) via the vehicle entrance 91.

[0035] Furthermore, the access control server 5 performs a person access control operation to manage the entry of the target person P into the second restricted area 9B via the person entrance gate 92. To perform the person access control operation, the access control server 5 obtains the person image IMG_P2 from the person gate device 3. Based on the person image IMG_P2, the access control server 5 determines whether the target person P located at the person entrance gate 92 is a registered person P_R who is scheduled to enter the restricted area 9. If the target person P is determined to be a registered person P_R, the access control server 5 permits the target person P to pass through the person entrance gate 92. In other words, the access control server 5 permits the target person P to enter the second restricted area 9B via the person entrance gate 92. On the other hand, if the target person P is determined not to be a registered person P_R, the access control server 5 does not permit the target person P to pass through the person entrance gate 92. In other words, the access control server 5 does not permit the target person P to enter the second restricted area 9B via the person entrance gate 92.

[0036] Furthermore, the entry management server 5 performs monitoring operations to monitor at least one of the target vehicle V and target person P located within the entry restriction area 9. To perform monitoring operations, the entry management server 5 acquires a monitoring image IMG_M from the monitoring camera 4. Based on the monitoring image IMG_M, the entry management server 5 monitors at least one of the target vehicle V and target person P located within the entry restriction area 9.

[0037] Furthermore, the access control server 5 performs a person exit management operation to manage the exit of the target person P from the second restricted area 9B via the person entrance gate 92. To perform the person exit management operation, the access control server 5 obtains a person image IMG_P2 from the person gate device 3. Based on the person image IMG_P2, the access control server 5 determines whether the target person P located at the person entrance gate 92 is a registered person P_R. If it is determined that the target person P is a registered person P_R, the access control server 5 permits the target person P to pass through the person entrance gate 92. In other words, the access control server 5 permits the target person P to exit the second restricted area 9B via the person entrance gate 92. On the other hand, if it is determined that the target person P is not a registered person P_R, the access control server 5 does not permit the target person P to pass through the person entrance gate 92. In other words, the access control server 5 does not permit the target person P to exit the second restricted area 9B via the person entrance gate 92.

[0038] Furthermore, the entry management server 5 performs vehicle exit management operations to manage the exit of target vehicle V from the entry restriction area 9 (particularly the first restriction area 9A) via the vehicle entrance gate 91. To perform vehicle exit management operations, the entry management server 5 obtains a vehicle image IMG_V from the vehicle gate device 1 and a person image IMG_P1 from the user terminal 2. Based on the vehicle image IMG_V, the entry management server 5 determines whether the target vehicle V located at the vehicle entrance gate 91 is a registered vehicle V_R. Furthermore, based on the person image IMG_P1, the entry management server 5 determines whether the target person P riding in the target vehicle V is a registered person P_R. If the target vehicle V is determined to be a registered vehicle V_R and the target person P is determined to be a registered person P_R, the entry management server 5 permits the target vehicle V to pass through the vehicle entrance gate 91. In other words, the entry management server 5 permits the target vehicle V and the target person P riding in the target vehicle V to exit the restricted entry area 9 (especially the first restricted area 9A) via the vehicle entrance 91. On the other hand, if the target vehicle V is determined not to be registered vehicle V_R, the entry management server 5 does not permit the target vehicle V to pass through the vehicle entrance 91. Also, if the target person P is determined not to be registered person P_R, the entry management server 5 does not permit the target vehicle V to pass through the vehicle entrance 91. In other words, the entry management server 5 does not permit the target vehicle V and the target person P riding in the target vehicle V to exit the restricted entry area 9 (especially the first restricted area 9A) via the vehicle entrance 91.

[0039] (2-1-2) Configuration of the vehicle gate device 1 Next, the configuration of the vehicle gate device 1 will be explained with reference to Figure 4. Figure 4 is a block diagram showing the configuration of the vehicle gate device 1.

[0040] As shown in Figure 4, the vehicle gate device 1 comprises a vehicle gate mechanism 11, a vehicle camera 12 which is a specific example of the "first imaging means" described in the appendix later, and a communication device 13.

[0041] The vehicle gate mechanism 11 is a device capable of controlling the passage of a target vehicle V through the vehicle entrance 91. The state of the vehicle gate mechanism 11 is controlled based on a vehicle gate control signal transmitted from the entrance management server 5. In the second embodiment, the state of the vehicle gate mechanism 11 is switchable between a closed state in which the target vehicle V cannot pass through the vehicle entrance 91 and an open state in which the target vehicle V can pass through the vehicle entrance 91. For example, if the vehicle gate mechanism 11 is equipped with a gate bar, the state of the vehicle gate mechanism 11 may be switchable between a closed state in which the gate bar is closed and an open state in which the gate bar is open.

[0042] The vehicle camera 12 captures an image of the target vehicle V located at the vehicle entrance 91, thereby generating a vehicle image IMG_V in which the target vehicle V is captured. The vehicle camera 12 transmits the generated vehicle image IMG_V to the entrance management server 5.

[0043] The communication device 13 can communicate with the access control server 5 via a communication network (not shown). In the second embodiment, the communication device 13 transmits the vehicle image IMG_V captured by the vehicle camera 12 to the access control server 5. In other words, the vehicle camera 12 transmits the vehicle image IMG_V to the access control server 5 using the communication device 13. Furthermore, in the second embodiment, the communication device 13 receives a vehicle gate control signal from the access control server 5. The state of the vehicle gate mechanism 11 is controlled based on the vehicle gate control signal received by the communication device 13.

[0044] (2-1-3) Configuration of User Terminal 2 Next, we will explain the configuration of user terminal 2 with reference to Figure 5. Figure 5 is a block diagram showing the configuration of user terminal 2.

[0045] As shown in Figure 5, the user terminal 2 includes a camera 20, which is a specific example of the "second imaging means" described in the appendix later, a computing device 21, a storage device 22, and a communication device 23. Furthermore, the user terminal 2 may also include an input device 24 and an output device 25. However, the user terminal 2 does not have to include at least one of the input device 24 and the output device 25. The camera 20, the computing device 21, the storage device 22, the communication device 23, the input device 24, and the output device 25 may be connected via a data bus 26.

[0046] Camera 20 generates a person image IMG_P1 by capturing an image of the target person P. Specifically, as described above, camera 20 generates a person image IMG_P1 by capturing an image of the target person P who is in the target vehicle V located at the vehicle entrance 91. Camera 20 transmits the generated person image IMG_P1 to the entrance management server 5.

[0047] The arithmetic unit 21 includes, for example, at least one of a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), and an FPGA (Field Programmable Gate Array). The arithmetic unit 21 reads a computer program. For example, the arithmetic unit 21 may read a computer program stored in the storage device 22. For example, the arithmetic unit 21 may read a computer program stored in a computer-readable and non-temporary recording medium using a recording medium reader (not shown) provided by the user terminal 2. The arithmetic unit 21 may obtain (i.e., download or read) a computer program from a device (not shown) located outside the user terminal 2 via the communication device 23 (or other communication device). The arithmetic unit 21 executes the read computer program. As a result, logical functional blocks for performing the actions that the user terminal 2 should perform are realized within the arithmetic unit 21. In other words, the arithmetic unit 21 can function as a controller for realizing logical functional blocks for performing the actions (in other words, processing) that the user terminal 2 should perform.

[0048] The storage device 22 is capable of storing desired data. For example, the storage device 22 may temporarily store a computer program executed by the arithmetic unit 21. The storage device 22 may temporarily store data that the arithmetic unit 21 uses temporarily while it is executing a computer program. The storage device 22 may store data that the user terminal 2 stores long-term. In this embodiment in particular, the storage device 22 may store the entry history DB 421. The storage device 22 may include at least one of RAM (Random Access Memory), ROM (Read Only Memory), hard disk drive, magneto-optical disk drive, SSD (Solid State Drive), and disk array device. In other words, the storage device 22 may include a non-temporary recording medium.

[0049] The communication device 23 can communicate with the access control server 5 via a communication network (not shown). In the second embodiment, the communication device 23 transmits the person image IMG_P1 captured by the camera 20 to the access control server 5. In other words, the camera 20 transmits the person image IMG_P1 to the access control server 5 using the communication device 23.

[0050] The input device 24 is a device that receives information input to the user terminal 2 from outside the user terminal 2. For example, the input device 24 may include an operating device (e.g., at least one of a keyboard, mouse, and touch panel) that can be operated by the operator of the user terminal 2. For example, the input device 24 may include a reading device that can read information recorded as data on a recording medium that can be attached externally to the user terminal 2.

[0051] The output device 25 is a device that outputs information to the outside of the user terminal 2. For example, the output device 25 may output information as an image. That is, the output device 25 may include a display device (so-called display) capable of displaying an image that shows the information to be output. For example, the output device 25 may output information as sound. That is, the output device 25 may include an audio device (so-called speaker) capable of outputting sound. For example, the output device 25 may output information onto paper. That is, the output device 25 may include a printing device (so-called printer) capable of printing the desired information onto paper.

[0052] (2-1-4) Configuration of the Human Gate Device 3 Next, the configuration of the human gate device 3 will be explained with reference to Figure 6. Figure 6 is a block diagram showing the configuration of the human gate device 3.

[0053] As shown in Figure 6, the person gate device 3 comprises a person gate mechanism 31, a person camera 32 which is a specific example of the "third imaging means" described in the appendix later, and a communication device 33.

[0054] The person gate mechanism 31 is a device capable of controlling the passage of a target person P through the person entrance 92. The state of the person gate mechanism 31 is controlled based on a person gate control signal transmitted from the entrance management server 5. In the second embodiment, the state of the person gate mechanism 31 is switchable between a closed state in which the target person P cannot pass through the person entrance 92 and an open state in which the target person P can pass through the person entrance 92. For example, if the person gate mechanism 31 is equipped with a gate bar, the state of the person gate mechanism 31 may be switchable between a closed state in which the gate bar is closed and an open state in which the gate bar is open.

[0055] The person camera 32 captures an image of the target person P located at the person entrance 92, thereby generating a person image IMG_P2 that includes the target person P. The person camera 32 then transmits the generated person image IMG_P to the entrance management server 5.

[0056] The communication device 33 can communicate with the access control server 5 via a communication network (not shown). In the second embodiment, the communication device 33 transmits the person image IMG_P2 captured by the person camera 32 to the access control server 5. In other words, the person camera 32 transmits the person image IMG_P2 to the access control server 5 using the communication device 33. Furthermore, in the second embodiment, the communication device 33 receives a person gate control signal from the access control server 5. The state of the person gate mechanism 31 is controlled based on the person gate control signal received by the communication device 33.

[0057] (2-1-5) Configuration of Access Control Server 5 Next, the configuration of the access control server 5 will be explained with reference to Figure 7. Figure 7 is a block diagram showing the configuration of the access control server 5.

[0058] As shown in Figure 7, the access control server 5 comprises a computing unit 51, a storage device 52, and a communication device 53. Furthermore, the access control server 5 may also include an input device 54 and an output device 55. However, the access control server 5 does not need to include at least one of the input device 54 and the output device 55. The computing unit 51, the storage device 52, the communication device 53, the input device 54, and the output device 55 may be connected via a data bus 56.

[0059] The arithmetic unit 51 includes, for example, at least one of a CPU, GPU, and FPGA. The arithmetic unit 51 reads a computer program. For example, the arithmetic unit 51 may read a computer program stored in the storage device 52. For example, the arithmetic unit 51 may read a computer program stored in a computer-readable and non-temporary recording medium using a recording medium reading device (not shown) provided by the access control server 5. The arithmetic unit 51 may obtain (i.e., download or read) a computer program from a device (not shown) located outside the access control server 5 via a communication device 53 (or other communication device). The arithmetic unit 51 executes the read computer program. As a result, logical functional blocks for performing the operations that the access control server 5 should perform are realized within the arithmetic unit 51. In other words, the arithmetic unit 51 can function as a controller for realizing logical functional blocks for performing the operations (in other words, processing) that the access control server 5 should perform.

[0060] As described above, in the second embodiment, the entry management server 5 performs vehicle entry management operations, person entry management operations, monitoring operations, person exit operations, and vehicle exit operations. For this reason, logical functional blocks for performing vehicle entry management operations, person entry management operations, monitoring operations, person exit operations, and vehicle exit operations are implemented within the computing device 51. Figure 7 shows an example of a logical functional block implemented within the computing device 51 for performing vehicle entry management operations, person entry management operations, monitoring operations, person exit operations, and vehicle exit operations. As shown in Figure 7, the arithmetic unit 51 includes a vehicle authentication unit 511, which is a specific example of the "first determination means" described in the appendix below; a person authentication unit 512, which is a specific example of the "second determination means" and "third determination means" described in the appendix below; a vehicle gate control unit 513, which is a specific example of the "entry management means" described in the appendix below; a person gate control unit 514, which is a specific example of the "entry management means" described in the appendix below; and a monitoring unit 515, which is a specific example of the "fourth determination means" and "warning means" described in the appendix below. The vehicle authentication unit 511, the person authentication unit 512, and the vehicle gate control unit 513 are mainly used to perform vehicle entry management operations and vehicle exit management operations. The person authentication unit 512 and the person gate control unit 514 are mainly used to perform person entry management operations and person exit management operations. The monitoring unit 515 is mainly used to perform monitoring operations.

[0061] The storage device 52 is capable of storing desired data. For example, the storage device 52 may temporarily store computer programs executed by the arithmetic unit 51. The storage device 52 may temporarily store data that the arithmetic unit 51 uses temporarily while it is executing a computer program. The storage device 52 may store data that the access control server 5 stores long-term. The storage device 52 may include at least one of RAM, ROM, hard disk drives, magneto-optical disk drives, SSDs, and disk array devices. In other words, the storage device 52 may include non-temporary recording media.

[0062] In the second embodiment, the storage device 52 may store a registration information database 521 that includes information about registered vehicles V_R and registered persons P_R that are scheduled to enter the restricted entry area 9.

[0063] An example of the data structure of the registration information DB521 is shown in Figures 8(a) to 8(c). As shown in Figure 8(a), the registration information DB521 contains multiple registration information records 5210. Each registration information record 5210 includes a record ID 5211 to identify the registration information record 5210, vehicle information 5212, and person information 5213. In other words, the registration information record 5210 is information in which the vehicle information 5212 and person information 5213 are associated by the record ID 5211.

[0064] Vehicle information 5212 is information about the registered vehicle V_R. Multiple registration information records 5210 may each contain multiple vehicle information records 5212 for multiple different registered vehicle V_Rs. An example of the data structure of vehicle information 5212 is shown in Figure 8(b). As shown in Figure 8(b), vehicle information 5212 may include vehicle number information about the registered vehicle V_R's vehicle number (i.e., the vehicle number written on the license plate). Vehicle information 5212 may include number information about the number of registered persons P_R who are scheduled to enter the restricted entry area 9 in the registered vehicle V_R. Vehicle information 5212 may include administrator information about the administrator of the registered vehicle V_R. Administrator information may include information about the administrator's name, the administrator's affiliation, and the administrator's contact information. Vehicle information 5212 may include vehicle permission area information about the vehicle entry permission area within the restricted entry area 9 in which the registered vehicle V_R is permitted to enter.

[0065] Person information 5213 is information about registered person P who is scheduled to enter restricted entry area 9 by riding in registered vehicle V_R, which corresponds to vehicle information 5212. If only one registered person P is scheduled to enter restricted entry area 9 by riding in a registered vehicle V_R, person information 5213 may include information about that one registered person P_R. If multiple registered persons P are scheduled to enter restricted entry area 9 by riding in a registered vehicle V_R, person information 5213 may include information about each of those multiple registered persons P_R.

[0066] An example of the data structure of person information 5213 is shown in Figure 8(c). As shown in Figure 8(c), person information 5213 may include a person ID for identifying the registered person P_R. Person information 5213 may include a registered image, which is an image of the registered person P_R. Person information 5213 may include person permission area information regarding the person permission area in which the registered person P_R is permitted to enter within the restricted entry area 9. Person information 5213 may include training information indicating whether or not the registered person P_R has received safety training in the factory, which is the restricted entry area 9. The training information may further include information regarding the date and time the registered person P_R received safety training.

[0067] The registration information record 5210 included in such a registration information DB 521 may have been previously registered by the administrator of the registered vehicle V_R or the registered person P_R. For example, the administrator of the registered vehicle V_R or the registered person P_R may send vehicle information 5212 and person information 5213 to the entry management server 5 along with an application request to apply for entry into the entry restriction area 9. The entry management server 5 may then newly register the registration information record 5210, which includes the vehicle information 5212 and person information 5213 sent by the administrator of the registered vehicle V_R or the registered person P_R, in the registration information DB 521.

[0068] In Figure 7, the communication device 53 can communicate with the vehicle gate device 1, the user terminal 2, the person gate device 3, and the surveillance camera 4, respectively, via a communication network (not shown). In the second embodiment, the communication device 53 receives a vehicle image IMG_V from the vehicle gate device 1. Furthermore, the communication device 53 transmits a vehicle gate control signal to the vehicle gate device 1 to control the state of the vehicle gate mechanism 11. Furthermore, the communication device 53 receives a person image IMG_P1 from the user terminal 2. Furthermore, the communication device 53 receives a person image IMG_P2 from the person gate device 3. Furthermore, the communication device 53 transmits a person gate control signal to the person gate device 3 to control the state of the person gate mechanism 31. Furthermore, the communication device 53 receives a surveillance image IMG_M from the surveillance camera 4.

[0069] The input device 54 is a device that receives information input to the access control server 5 from outside the access control server 5. For example, the input device 54 may include an operating device (for example, at least one of a keyboard, mouse, and touch panel) that can be operated by an operator of the access control server 5. For example, the input device 54 may include a reading device that can read information recorded as data on a recording medium that can be attached externally to the access control server 5.

[0070] The output device 55 is a device that outputs information to the outside of the access control server 5. For example, the output device 55 may output the information as an image. That is, the output device 55 may include a display device (so-called display) capable of displaying an image that shows the information to be output. For example, the output device 55 may output the information as sound. That is, the output device 55 may include an audio device (so-called speaker) capable of outputting sound. For example, the output device 55 may output the information on paper. That is, the output device 55 may include a printing device (so-called printer) capable of printing the desired information on paper.

[0071] (2-2) Actions performed by the access control server 5 Next, we will explain the operations performed by the access control server 5. As mentioned above, the access control server 5 performs vehicle access control operations, person access control operations, monitoring operations, person exit operations, and vehicle exit operations. Therefore, the following will explain the vehicle access control operations, person access control operations, monitoring operations, person exit operations, and vehicle exit operations in order.

[0072] (2-2-1) Vehicle entry management operation First, we will explain the flow of the vehicle entry management operation, referring to Figure 9. Figure 9 is a flowchart showing the flow of the vehicle entry management operation.

[0073] As shown in Figure 9, the vehicle authentication unit 511 acquires a vehicle image IMG_V from the vehicle gate device 1 (step S101). When the target vehicle V reaches the vehicle entrance 91, the vehicle gate device 1 uses the vehicle camera 12 to capture an image of the target vehicle V located at the vehicle entrance 91. Specifically, if the target vehicle V enters the restricted entry area 9 via the vehicle entrance 91, the vehicle camera 12 captures an image of the target vehicle V located outside the restricted entry area 9. The entry management server 5 may initiate the vehicle entry management operation shown in Figure 9 when the vehicle camera 12 captures an image of the target vehicle V located outside the restricted entry area 9.

[0074] Subsequently, the vehicle authentication unit 511 authenticates the target vehicle V using the vehicle image IMG_V acquired in step S101 and the registration information DB521 stored in the storage device 52 (step S102). In the second embodiment, the operation of authenticating the target vehicle V means the operation of determining whether the target vehicle V is a registered vehicle V_R. To authenticate the target vehicle V, the vehicle authentication unit 511 compares the vehicle number of the target vehicle V captured in the vehicle image IMG_V with the vehicle number of the registered vehicle V_R indicated by the vehicle information 5212 contained in the registration information DB521. If the registration information DB521 contains vehicle information 5212 indicating the vehicle number of the registered vehicle V_R which is the same as the vehicle number of the target vehicle V, the vehicle authentication unit 511 determines that the target vehicle V is a registered vehicle V_R. In other words, the vehicle authentication unit 511 determines that the authentication of the target vehicle V has been successful. On the other hand, if the registration information DB521 does not contain vehicle information 5212 indicating the vehicle number of registered vehicle V_R which has the same vehicle number as the target vehicle V, the vehicle authentication unit 511 determines that the target vehicle V is not registered vehicle V_R. In other words, the vehicle authentication unit 511 determines that the authentication of the target vehicle V has failed.

[0075] If the authentication of the target vehicle V fails as a result of the authentication in step S102 (step S103: No), then the target vehicle V located at the vehicle entrance 91 is not scheduled to enter the restricted entry area 9. Therefore, in this case, the vehicle gate control unit 513 does not permit the target vehicle V to pass through the vehicle entrance 91 (step S109). Specifically, the vehicle gate control unit 513 generates a vehicle gate control signal to set the state of the vehicle gate mechanism 11 to the closed state. The vehicle gate control unit 513 transmits the generated vehicle gate control signal to the vehicle gate device 1. As a result, the state of the vehicle gate mechanism 11 is set to the closed state, and the target vehicle V cannot pass through the vehicle entrance 91.

[0076] If the target vehicle V is not permitted to pass through the vehicle entrance 91, the vehicle gate control unit 513 may output warning information to a designated user informing them that the target vehicle V was not permitted to pass through the vehicle entrance 91. For example, based on the administrator information contained in the vehicle information 5212, the vehicle gate control unit 513 may output warning information to the administrator of the target vehicle V (i.e., registered vehicle V_R) informing them that the target vehicle V was not permitted to pass through the vehicle entrance 91. For example, the vehicle gate control unit 513 may output warning information to the operator of the entrance management system SYS informing them that the target vehicle V was not permitted to pass through the vehicle entrance 91. The user may investigate the target vehicle V that was not permitted to pass through the vehicle entrance 91.

[0077] On the other hand, if the authentication of the target vehicle V is successful as a result of the authentication in step S102 (step S103: Yes), the person authentication unit 512 acquires a person image IMG_P1 from the user terminal 2 (step S104). Specifically, when the target vehicle V reaches the vehicle entrance 91, the user terminal 2 equipped by each target person P riding in the target vehicle V uses the camera 20 to capture an image of each target person P riding in the target vehicle V. In other words, each target person P riding in the target vehicle V uses the user terminal 2 equipped by each target person P to capture an image of themselves. The person authentication unit 512 acquires a person image IMG_P1 for each target person P riding in the target vehicle V.

[0078] Subsequently, the person authentication unit 512 authenticates the target person P using each person image IMG_P1 acquired in step S104 and the registration information DB 521 stored in the storage device 52 (step S105). In the second embodiment, the operation of authenticating the target person P means the operation of determining whether or not the target person P is a registered person P_R. To authenticate the target person P, the person authentication unit 512 acquires person information 5213 associated with the vehicle information 5212 related to the target vehicle V authenticated in step S102 from the registration information DB 521. The person authentication unit 512 compares each person image IMG_P1 acquired in step S104 with the registration image included in the person information 5213 to determine whether or not each target person P is a registered person P_R who is scheduled to enter the restricted entry area 9 by riding in the target vehicle V authenticated in step S102. For example, the person authentication unit 512 may extract feature quantities for each target person P (e.g., facial feature quantities for each target person P) based on each person image IMG_P1, and extract feature quantities for registered person P_R (e.g., facial feature quantities for registered person P_R) based on the registered image. Subsequently, the person authentication unit 512 may determine that each target person P is registered person P_R if the similarity between the feature quantities of each target person P and the feature quantities of registered person P_R exceeds a predetermined threshold. In other words, the person authentication unit 512 determines that the authentication of each target person P is successful. On the other hand, the person authentication unit 512 may determine that each target person P is not registered person P_R if the similarity between the feature quantities of each target person P and the feature quantities of registered person P_R falls below a predetermined threshold. In other words, the person authentication unit 512 determines that the authentication of each target person P has failed.

[0079] If, as a result of the authentication in step S105, the authentication of at least one subject person P who was subject to authentication in step S105 fails (step S106: No), then subject person P who is not scheduled to enter the restricted entry area 9 is on board the subject vehicle V. Therefore, in this case, the vehicle gate control unit 513 does not permit the subject vehicle V to pass through the vehicle entrance 91 (step S109).

[0080] On the other hand, if, as a result of the authentication in step S105, all target persons P who were subject to authentication in step S105 are successfully authenticated (step S106: Yes), the person authentication unit 512 determines whether the number of target persons P who were successfully authenticated in step S105 is the same as the number of registered persons P_R who are scheduled to enter the restricted entry area 9 by riding in the target vehicle V authenticated in step S102 (step S107). As mentioned above, information regarding the number of registered persons P_R who are scheduled to enter the restricted entry area 9 by riding in the target vehicle V is included in the vehicle information 5212 stored in the storage device 52.

[0081] If, as a result of the determination in step S107, it is determined that the number of target persons P who have been successfully authenticated is not the same as the number of registered persons P_R (step S107: No), it is assumed that there are registered persons P_R who are scheduled to enter the restricted entry area 9 by boarding the target vehicle V, but are not actually boarding the target vehicle V. In this case, the vehicle gate control unit 513 does not have to permit the target vehicle V to pass through the vehicle entrance 91 (step S109).

[0082] On the other hand, if the determination in step S107 determines that the number of authenticated target persons P is the same as the number of registered persons P_R (step S107: Yes), then it is assumed that all registered persons P_R who are scheduled to enter the restricted entry area 9 by riding in target vehicle V are on board. In this case, the vehicle gate control unit 513 permits target vehicle V to pass through the vehicle entrance 91 (step S108). Specifically, the vehicle gate control unit 513 generates a vehicle gate control signal to set the state of the vehicle gate mechanism 11 to the open state. The vehicle gate control unit 513 transmits the generated vehicle gate control signal to the vehicle gate device 1. As a result, the state of the vehicle gate mechanism 11 is set to the open state, and target vehicle V can pass through the vehicle entrance 91.

[0083] (2-2-2) Person entry management operation Next, we will explain the flow of the person entry management operation, referring to Figure 10. Figure 10 is a flowchart showing the flow of the person entry management operation.

[0084] As shown in Figure 10, the person authentication unit 512 acquires a person image IMG_P2 from the person gate device 3 (step S111). When the person P reaches the person entrance 92, the person gate device 3 uses the person camera 32 to image the person P located at the person entrance 92. Specifically, when the person P enters the second restricted area 9B via the person entrance 92, the person camera 32 images the person P located outside the second restricted area 9B (i.e., the first restricted area 9A). The entry management server 5 may initiate the person entry management operation shown in Figure 10 when the person camera 32 images the person P located outside the second restricted area 9B.

[0085] Subsequently, the person authentication unit 512 authenticates the target person P using the person image IMG_P2 acquired in step S111 and the registration information DB521 stored in the storage device 52 (step S112). Note that the operation to authenticate the target person P in step S112 may be the same as the operation to authenticate the target person P in step S105 of Figure 9 described above. For this reason, a detailed explanation of the operation to authenticate the target person P in step S112 of Figure 10 is omitted.

[0086] If the authentication of person P fails in step S112 (step S113: No), then person P, who is located at the person entrance 92, is not scheduled to enter the restricted entry area 9. Therefore, in this case, the person gate control unit 514 does not permit person P to pass through the person entrance 92 (step S117). Specifically, the person gate control unit 514 generates a person gate control signal to set the state of the person gate mechanism 31 to the closed state. The person gate control unit 514 transmits the generated person gate control signal to the person gate device 3. As a result, the state of the person gate mechanism 31 is set to the closed state, and person P cannot pass through the person entrance 92.

[0087] If person P is not permitted to pass through the person entrance 92, the person gate control unit 514 may output warning information to a designated user informing them that person P was not permitted to pass through the person entrance 92. For example, based on the administrator information included in the vehicle information 5212, the person gate control unit 514 may output warning information to the administrator of the vehicle V (i.e., registered vehicle V_R) in which person P was riding, informing them that person P was not permitted to pass through the person entrance 92. For example, the person gate control unit 514 may output warning information to the operator of the entrance management system SYS informing them that person P was not permitted to pass through the person entrance 92. The user may investigate person P who was not permitted to pass through the person entrance 92.

[0088] On the other hand, if the authentication of the target person P is successful as a result of the authentication in step S112 (step S113: Yes), the person gate control unit 514 determines whether or not the authentication of the target person P at the vehicle entrance 91 was successful (step S114).

[0089] If the determination in step S114 is found to be unsuccessful in authenticating the subject person P at the vehicle entrance 91 (step S114: No), then the subject person P, who has not been authenticated by the entrance management server 5 at the vehicle entrance 91, is located at the person entrance 92. For example, the subject person P may be located at the person entrance 92 after illegally passing through the vehicle entrance 91 by hiding inside the vehicle V without being authenticated by the entrance management server 5. In this case, the person gate control unit 514 does not permit the subject person P to pass through the person entrance 92 (step S117).

[0090] On the other hand, if the determination in step S114 determines that the authentication of the target person P at the vehicle entrance 91 was successful (step S114: Yes), the person gate control unit 514 determines whether the target person P has received safety training in the factory, which is the restricted entry area 9 (step S115). As described above, the person information 5213 stored in the storage device 52 includes training information indicating whether the registered person P_R has received safety training. In this case, the person gate control unit 514 may determine whether the target person P has received safety training by determining, based on the training information, whether the target person P is the registered person P_R who has received safety training.

[0091] If the determination in step S115 determines that person P has not received safety training (step S115: No), it is assumed that it is preferable for person P to enter the restricted entry area 9 after receiving safety training. In this case, the person gate control unit 514 does not permit person P to pass through the person entrance 92 (step S117). The person gate control unit 514 may then prompt person P to receive safety training. For example, if the person gate device 3 is equipped with a display (or any output device), the person gate control unit 514 may control the display to show an image prompting person P to receive safety training.

[0092] On the other hand, if the determination in step S115 determines that the person P has received safety training (step S115: Yes), the person gate control unit 514 permits the person P to pass through the person entrance 92 (step S116). Specifically, the person gate control unit 514 generates a person gate control signal to set the state of the person gate mechanism 31 to the open state. The person gate control unit 514 transmits the generated person gate control signal to the person gate device 3. As a result, the state of the person gate mechanism 31 is set to the open state, and the person P can pass through the person entrance 92.

[0093] (2-2-3) Monitoring operation Next, we will explain the monitoring process flow, referring to Figure 11. Figure 11 is a flowchart showing the monitoring process flow.

[0094] As shown in Figure 11, the monitoring unit 515 acquires the monitoring image IMG_M from the monitoring camera 4 (step S121). The monitoring camera 4 captures the imaging range 41 at a predetermined imaging rate. The access control server 5 may start the monitoring operation shown in Figure 11 when the monitoring camera 4 generates the monitoring image IMG_M. The access control server 5 may also start the monitoring operation shown in Figure 11 when the monitoring camera 4 transmits the monitoring image IMG_M to the access control server 5.

[0095] Subsequently, the monitoring unit 515 analyzes the monitoring image IMG_M acquired in step S121 to determine whether or not a vehicle (specifically, the target vehicle V that entered the restricted entry area 9) is visible in the monitoring image IMG_M (step S122).

[0096] If, as a result of the determination in step S122, it is determined that the target vehicle V is captured in the monitoring image IMG_M (step S122: Yes), the monitoring unit 515 authenticates the target vehicle V using the monitoring image IMG_M acquired in step S121 and the registration information DB 521 stored in the storage device 52 (step S123). Note that the operation to authenticate the target vehicle V in step S123 may be the same as the operation to authenticate the target vehicle V in step S102 in Figure 9. For this reason, a detailed explanation of the operation to authenticate the target vehicle V in step S123 in Figure 11 is omitted.

[0097] On the other hand, if the determination in step S122 determines that the target vehicle V is not visible in the monitored image IMG_M (step S122: No), the monitoring unit 515 does not need to perform the operation in step S123.

[0098] Furthermore, the monitoring unit 515 analyzes the monitoring image IMG_M acquired in step S121 to determine whether or not a person (specifically, the target person P who entered the restricted entry area 9) is visible in the monitoring image IMG_M (step S124).

[0099] If, as a result of the determination in step S124, it is determined that the target person P is captured in the monitoring image IMG_M (step S124: Yes), the monitoring unit 515 authenticates the target person P using the monitoring image IMG_M acquired in step S121 and the registration information DB 521 stored in the storage device 52 (step S125). Note that the operation to authenticate the target person P in step S125 may be the same as the operation to authenticate the target person P in step S105 in Figure 9. For this reason, a detailed explanation of the operation to authenticate the target person P in step S125 in Figure 11 is omitted.

[0100] On the other hand, if the determination in step S124 determines that the subject person P is not visible in the monitored image IMG_M (step S124: No), the monitoring unit 515 does not need to perform the operation in step S125.

[0101] Subsequently, the monitoring unit 515 determines whether the target vehicle V authenticated in step S123 is in an abnormal state (step S126). Furthermore, the monitoring unit 515 determines whether the target person P authenticated in step S125 is in an abnormal state (step S126).

[0102] For example, as described above, the registration information DB521 includes vehicle permission area information as part of the vehicle information 5212, relating to the vehicle entry permission area in which the registered vehicle V_R is permitted to enter within the entry restriction area 9. In this case, the monitoring unit 515 may determine whether the target vehicle V is in an abnormal state by determining whether the target vehicle V authenticated in step S123 is located in an area different from the vehicle entry permission area. Specifically, because the target vehicle V authenticated in step S123 is being imaged by the monitoring camera 4, the monitoring unit 515 can determine the current position of the target vehicle V from the position of the imaging range 41 of the monitoring camera 4. The information regarding the position of the imaging range 41 of the monitoring camera 4 may be known information to the monitoring unit 515. Furthermore, the monitoring unit 515 can identify the vehicle entry permission area for the registered vehicle V_R corresponding to the target vehicle V based on the registration information DB521. As a result, the monitoring unit 515 can determine whether the target vehicle V is located in an area different from the vehicle entry permission area. If it is determined that the target vehicle V is located in an area different from the permitted vehicle entry area, it is assumed that the target vehicle V is located in an area where entry is not permitted. In this case, the monitoring unit 515 may determine that the target vehicle V is in an abnormal state.

[0103] For example, as described above, the registration information DB 521 includes, as part of the person information 5213, person permission area information relating to the person permission area in which the registered person P_R is permitted to enter within the restricted entry area 9. In this case, the monitoring unit 515 may determine whether the person P authenticated in step S125 is located in an area different from the person permission area, thereby determining whether the person P is in an abnormal state. Specifically, because the person P authenticated in step S125 is being imaged by the surveillance camera 4, the monitoring unit 515 can determine the current location of the person P from the imaging range 41 of the surveillance camera 4. Furthermore, the monitoring unit 515 can identify the person permission area for the registered person P_R corresponding to the person P based on the registration information DB 521. As a result, the monitoring unit 515 can determine whether the person P is located in an area different from the person permission area. If it is determined that the subject person P is located in an area different from the area where entry is permitted for persons, it is assumed that the subject person P is located in an area where entry is not permitted. In this case, the monitoring unit 515 may determine that the subject person P is in an abnormal state.

[0104] In addition, for example, the monitoring unit 515 may calculate the driving speed of the target vehicle V by analyzing the monitoring image IMG_M, and if the calculated driving speed exceeds the speed limit, it may determine that the target vehicle V is in an abnormal state. If the target vehicle V is a special vehicle for which the period during which it is permitted to drive on the road is limited, the monitoring unit 515 may identify the period during which the target vehicle V is permitted to drive by analyzing the monitoring image IMG_M, and if the identified period has already expired, it may determine that the target vehicle V is in an abnormal state. For example, the monitoring unit 515 may determine whether or not the target person P is smoking by analyzing the monitoring image IMG_M, and if the target person P is smoking in a place other than a smoking area, it may determine that the target person P is in an abnormal state. For example, the monitoring unit 515 may determine that the target vehicle V is in an abnormal state if authentication of the target vehicle V fails in step S123 (i.e., the target vehicle V, which is not the registered vehicle V_R, is located within the entry restriction area 9). For example, the monitoring unit 515 may determine that the target person P is in an abnormal state if authentication of the target person P fails in step S125 (i.e., the target person P, who is not a registered person P_R, is located within the restricted entry area 9).

[0105] If the monitoring unit 515 determines that the target vehicle V is in an abnormal state, it may output warning information to a designated user that the target vehicle V is in an abnormal state. For example, the monitoring unit 515 may output warning information to the administrator of the target vehicle V (i.e., registered vehicle V_R) that the target vehicle V is in an abnormal state, based on the administrator information contained in the vehicle information 5212. For example, the monitoring unit 515 may output warning information to the operator of the entry management system SYS that the target vehicle V is in an abnormal state. The user may investigate the target vehicle V that is in an abnormal state.

[0106] If it is determined that the target person P is in an abnormal state, the monitoring unit 515 may output warning information to a designated user warning that the target person P is in an abnormal state. For example, based on the administrator information contained in the vehicle information 5212, the monitoring unit 515 may output warning information to the administrator of the target vehicle V (i.e., registered vehicle V_R) in which the target person P was riding, warning that the target person P is in an abnormal state. For example, the monitoring unit 515 may output warning information to the operator of the entry management system SYS warning that the target person P is in an abnormal state. The user may investigate the target person P who is in an abnormal state.

[0107] (2-2-4) Person exit management operation Next, we will explain the flow of the person exit management operation, referring to Figure 12. Figure 12 is a flowchart showing the flow of the person exit management operation.

[0108] As shown in Figure 12, the person authentication unit 512 acquires a person image IMG_P2 from the person gate device 3 (step S131). When the person P reaches the person entrance 92, the person gate device 3 uses the person camera 32 to image the person P located at the person entrance 92. Specifically, when the person P exits the second restricted area 9B via the person entrance 92, the person camera 32 images the target vehicle V located inside the second restricted area 9B. The entrance management server 5 may initiate the person exit management operation shown in Figure 12 when the person camera 32 has imaged the person P located inside the second restricted area 9B.

[0109] Subsequently, the person authentication unit 512 authenticates the target person P using the person image IMG_P2 acquired in step S111 and the registration information DB521 stored in the storage device 52 (step S132). Note that the operation to authenticate the target person P in step S132 may be the same as the operation to authenticate the target person P in step S112 in Figure 10 described above. For this reason, a detailed explanation of the operation to authenticate the target person P in step S132 in Figure 12 is omitted.

[0110] If the authentication of person P fails in step S132 (step S133: No), it is assumed that person P, located at the person entrance 92, was staying in the restricted entry area 9 even though they were not scheduled to enter the restricted entry area 9. In this case, the person gate control unit 514 does not permit person P to pass through the person entrance 92 (step S135). Note that the operation in step S135 may be the same as the operation in step S117 in Figure 10 described above. For this reason, a detailed explanation of the operation in step S135 in Figure 12 is omitted.

[0111] If person P is not permitted to pass through the person entrance 92, the person gate control unit 514 may output warning information to a designated user informing them that person P was not permitted to pass through the person entrance 92. For example, based on the administrator information included in the vehicle information 5212, the person gate control unit 514 may output warning information to the administrator of the vehicle V (i.e., registered vehicle V_R) in which person P was riding, informing them that person P was not permitted to pass through the person entrance 92. For example, the person gate control unit 514 may output warning information to the operator of the entry management system SYS informing them that person P was not permitted to pass through the person entrance 92. The user may investigate person P who was not permitted to pass through the person entrance 92 (i.e., person P who was staying in the entry restriction area 9 despite not being scheduled to enter the entry restriction area 9).

[0112] On the other hand, if the authentication of the target person P is successful as a result of the authentication in step S112 (step S133: Yes), the person gate control unit 514 permits the target person P to pass through the person entrance 92 (step S134). Note that the operation of step S134 may be the same as the operation of step S116 in Figure 10 described above. For this reason, a detailed explanation of the operation of step S134 in Figure 12 is omitted.

[0113] (2-2-5) Vehicle Exit Management Operation Next, we will explain the flow of the vehicle exit management operation, referring to Figure 13. Figure 13 is a flowchart showing the flow of the vehicle exit management operation.

[0114] As shown in Figure 13, the vehicle authentication unit 511 acquires a vehicle image IMG_V from the vehicle gate device 1 (step S141). When the target vehicle V reaches the vehicle entrance 91, the vehicle gate device 1 uses the vehicle camera 12 to capture an image of the target vehicle V located at the vehicle entrance 91. Specifically, when the target vehicle V exits the restricted entry area 9 via the vehicle entrance 91, the vehicle camera 12 captures an image of the target vehicle V located inside the restricted entry area 9 (specifically, the first restricted area 9A). The entry management server 5 may initiate the vehicle entry management operation shown in Figure 9 when the vehicle camera 12 captures an image of the target vehicle V located inside the restricted entry area 9.

[0115] Subsequently, the entry management server 5 performs steps S142 to S149, which may be the same as steps S102 to S109 of the vehicle entry management operation shown in Figure 9. That is, the vehicle authentication unit 511 authenticates the target vehicle V using the vehicle image IMG_V acquired in step S141 and the registration information DB 521 stored in the storage device 52 (step S142). If the authentication of the target vehicle V fails as a result of the authentication in step S142 (step S143: No), the vehicle gate control unit 513 does not allow the target vehicle V to pass through the vehicle entrance 91 (step S149). On the other hand, if the authentication of the target vehicle V is successful as a result of the authentication in step S142 (step S143: Yes), the person authentication unit 512 acquires the person image IMG_P1 from the user terminal 2 (step S144). Subsequently, the person authentication unit 512 authenticates the target person P using the individual person image IMG_P1 acquired in step S144 and the registration information DB521 stored in the storage device 52 (step S145). If, as a result of the authentication in step S145, authentication of at least one target person P that was the subject of authentication in step S145 fails (step S146: No), the vehicle gate control unit 513 does not permit the target vehicle V to pass through the vehicle entrance 91 (step S149). On the other hand, if, as a result of the authentication in step S145, authentication of all target person P that was the subject of authentication in step S145 is successful (step S146: Yes), the person authentication unit 512 determines whether the number of target person P that was successfully authenticated in step S145 is the same as the number of registered person P_R that is scheduled to enter the restricted entry area 9 by riding in the target vehicle V authenticated in step S142 (and consequently, is scheduled to exit the restricted entry area 9) (step S147). If, as a result of the determination in step S147, it is determined that the number of target persons P who have been successfully authenticated is not the same as the number of registered persons P_R (step S147: No), the vehicle gate control unit 513 does not have to permit the target vehicle V to pass through the vehicle entrance 91 (step S149).On the other hand, if the determination in step S147 is found to be true, the number of authenticated individuals P is equal to the number of registered individuals P_R (step S147: Yes), the vehicle gate control unit 513 permits the target vehicle V to pass through the vehicle entrance 91 (step S148).

[0116] (2-3) Technical effects of the SYS access control system As explained above, the entry management system SYS uses the vehicle image IMG_V, the person image IMG_P1, and the registration information DB521 to determine whether or not to allow the target vehicle V to pass through the vehicle entrance 91. Therefore, the target person P does not need to get out of the target vehicle V at the vehicle entrance 91 and fill out the necessary information on paperwork in order to enter the restricted entry area 9. As a result, the target person P can enter the restricted entry area 9 while remaining in the target vehicle V. Consequently, the time required to enter the restricted entry area 9 is shortened. As a result, the possibility of a large number of target vehicles V wishing to enter the restricted entry area 9 accumulating at the vehicle entrance 91 (resulting in congestion) is reduced. Therefore, the entry management system SYS can solve the technical problem of a large number of target vehicles V wishing to enter the restricted entry area 9 potentially accumulating at the vehicle entrance 91.

[0117] Furthermore, the entry management system SYS permits vehicle V to pass through the vehicle entrance 91 only if it determines that the vehicle V is registered vehicle V_R and that the person P is registered person P_R. Therefore, compared to a case where vehicle V is permitted to pass through the vehicle entrance 91 even when vehicle V is determined to be registered vehicle V_R but person P is not, the entry management system SYS can more effectively prevent suspicious person P from entering the restricted entry area 9. Similarly, compared to a case where vehicle V is permitted to pass through the vehicle entrance 91 even when person P is determined to be registered person P_R but vehicle V is not, the entry management system SYS can more effectively prevent suspicious person P from entering the restricted entry area 9. Therefore, the entry management system SYS can solve the technical problem of a suspicious person P potentially entering the restricted entry area 9.

[0118] Furthermore, the entry management system SYS permits vehicle V to pass through the vehicle entrance 91 if the number of authenticated individuals P is the same as the number of registered individuals P_R who are scheduled to enter the restricted entry area 9 in a successfully authenticated vehicle V. Therefore, compared to the case where the number of individuals P is not considered, the entry management system SYS can more effectively prevent suspicious individuals P from entering the restricted entry area 9.

[0119] Furthermore, in addition to determining whether to permit the vehicle V to pass through the vehicle entrance 91, the entry management system SYS also determines whether to permit the person P to pass through the person entrance 92. Therefore, even if a person P has illegally passed through the vehicle entrance 91, that person P will not be permitted to pass through the person entrance 92. As a result, the entry management system SYS can more effectively prevent suspicious persons P from entering the restricted entry area 9 (especially the second restricted area 9B).

[0120] Furthermore, the access control system SYS does not permit person P who has not received safety training to pass through the person entrance 92. Therefore, compared to a case where person P who has not received safety training is permitted to pass through the person entrance 92, the access control system SYS can more reliably ensure safety within the factory, which is the restricted access area 9.

[0121] Furthermore, the entry management system SYS performs monitoring operations to monitor the actions of person P who has entered the restricted entry area 9 within that area. As a result, the entry management system SYS can identify at least one of the person P and vehicle V that are in an abnormal state. Consequently, compared to when no monitoring operations are performed, the entry management system SYS can appropriately resolve the abnormal state.

[0122] (2-4) Variations In the above explanation, in the vehicle entry management operation shown in Figure 9, the entry management server 5 determines in step S105 whether the number of target persons P who have been successfully authenticated is the same as the number of registered persons P_R who are scheduled to enter the restricted entry area 9 by riding in the target vehicle V authenticated in step S102 (step S107 in Figure 9). However, the entry management server 5 does not have to perform the operation in step S107 in Figure 9.

[0123] In the explanation above, in the person entry management operation shown in Figure 10, the entry management server 5 determines whether or not the authentication of the target person P at the vehicle entrance 91 was successful (step S114 in Figure 10). However, the entry management server 5 does not have to perform the operation in step S114 in Figure 10.

[0124] In the above explanation, in the person entry management operation shown in Figure 10, the entry management server 5 determines whether or not the target person P has received safety training (step S115 in Figure 10). However, the entry management server 5 does not have to perform the operation in step S115 in Figure 10. If the entry management server 5 does not perform the operation in step S115 in Figure 10, the registration information DB 521 does not have to include training information indicating whether or not the registered person P_R has received safety training. Alternatively, in addition to or instead of determining whether or not the target person P has received safety training in the person entry management operation shown in Figure 10, the entry management server 5 may determine in the vehicle entry management operation shown in Figure 9 whether or not the target person P located at the vehicle entrance 91 (i.e., the target person P riding in the target vehicle V located at the vehicle entrance 91) has received safety training. In this case, if it is determined that the target person P has not received safety training, the entry management server 5 does not have to permit the target vehicle V to pass through the vehicle entrance 91. Furthermore, the access control server 5 may prompt the person P to take safety training.

[0125] In the person entry management operation shown in Figure 10, the entry management server 5 may determine whether a predetermined validity period has elapsed since the last time the target person P received safety training. In other words, the entry management server 5 may determine whether the target person P received safety training within the validity period. If it is determined that the validity period has elapsed since the last time the target person P received safety training (i.e., the target person P did not receive safety training within the validity period), the entry management server 5 does not have to permit the target person P to pass through the person entry gate 92. In that case, the entry management server 5 may then prompt the target person P to receive safety training.

[0126] In the vehicle exit management operation shown in Figure 13, if, despite the target vehicle V having exited the restricted entry area 9, registered person P_R, who is scheduled to enter the restricted entry area 9 by boarding the target vehicle V (and consequently, is scheduled to exit the restricted entry area 9), has not exited the restricted entry area 9, the vehicle gate control unit 513 may output warning information to a designated user informing them that registered person P_R has not exited the restricted entry area 9. For example, the vehicle gate control unit 513 may output warning information to the administrator of the target vehicle V informing them that registered person P_R has not exited the restricted entry area 9. For example, the vehicle gate control unit 513 may output warning information to the operator of the entry management system SYS informing them that registered person P_R has not exited the restricted entry area 9. The user may investigate the reason why registered person P_R has not exited the restricted entry area 9.

[0127] In the vehicle exit management operation shown in Figure 13, if a registered person P_R, who is scheduled to enter the restricted entry area 9 by boarding the vehicle V (and consequently, is scheduled to exit the restricted entry area 9), has already exited the restricted entry area 9, even though the target vehicle V has not yet exited the restricted entry area 9, the vehicle gate control unit 513 may output warning information to a designated user warning that the target vehicle V has not exited the restricted entry area 9. For example, the vehicle gate control unit 513 may output warning information to the administrator of the target vehicle V warning that the target vehicle V has not exited the restricted entry area 9. For example, the vehicle gate control unit 513 may output warning information to the operator of the entry management system SYS warning that the target vehicle V has not exited the restricted entry area 9. The user may investigate the reason why the target vehicle V has not exited the restricted entry area 9.

[0128] In the above explanation, in the vehicle exit management operation shown in Figure 13, the entry management server 5 determines in step S145 whether the number of target persons P who have been successfully authenticated is the same as the number of registered persons P_R who are scheduled to enter the restricted entry area 9 by boarding the target vehicle V authenticated in step S142 (and consequently, are scheduled to exit the restricted entry area 9) (step S147 in Figure 13). However, the entry management server 5 does not have to perform the operation in step S147 in Figure 13.

[0129] In the above explanation, in the vehicle exit management operation shown in Figure 13, the entry management server 5 authenticates the target person P (steps S144 to S146 in Figure 13). However, the entry management server 5 does not have to perform the operations in steps S144 to S146 in Figure 13. In this case, the target person P can exit the restricted entry area 9 by boarding a different vehicle from the target vehicle V that he boarded to enter the restricted entry area 9. For example, if the first target person P and the second target person P2 board the first target vehicle V and enter the restricted entry area 9, the first target person P who completes his work before the second target person P can exit the restricted entry area 9 without waiting for the second target person P to complete his work. This ensures flexibility in exit time.

[0130] In the above description, the access control server 5 performs vehicle access control operations, human access control operations, monitoring operations, human exit operations, and vehicle exit operations. However, the access control server 5 does not have to perform at least one of the vehicle access control operations, human access control operations, monitoring operations, human exit operations, and vehicle exit operations. If the access control server 5 does not perform vehicle access control operations and vehicle exit control operations, the access control system SYS does not have to be equipped with a vehicle gate device 1 and a user terminal 2, and the access control server 5 does not have to be equipped with a vehicle authentication unit 511 and a vehicle gate control unit 513. If the access control server 5 does not perform human access control operations and human exit control operations, the access control system SYS does not have to be equipped with a human gate device 3, and the access control server 5 does not have to be equipped with a human authentication unit 512 and a human gate control unit 514. If the access control server 5 does not perform monitoring operations, the access control system SYS does not have to be equipped with a monitoring camera 4, and the access control server 5 does not have to be equipped with a monitoring unit 515.

[0131] In the above description, a person entrance gate 92 is provided in the restricted entry area 9. However, a person entrance gate 92 is not required in the restricted entry area 9. The restricted entry area 9 is not required to be divided into a first restricted area 9A and a second restricted area 9B by a person entrance gate 92. In this case, the entry management system SYS is not required to have a person gate device 2 located at the person entrance gate 92. The entry management server 5 is not required to perform person entry management operations and person exit management operations based on the person image IMG_P2 generated by the person gate device 2.

The process involves generating a vehicle image by capturing images of the vehicle located at the vehicle entrance through which the vehicle must pass in order to enter the restricted entry area. By comparing the vehicle number of the target vehicle captured in the vehicle image with the vehicle number of the registered vehicle indicated in the vehicle information, it is determined whether or not the target vehicle located at the vehicle entrance is the registered vehicle. By capturing images of the target person riding in the target vehicle located at the vehicle entrance, a person image is generated. By comparing the aforementioned person image with the registered image indicated by the person information, it is determined whether or not the person riding in the target vehicle is the registered person. If the vehicle located at the vehicle entrance is determined to be the registered vehicle and the person riding in the vehicle is determined to be the registered person, the vehicle shall be permitted to pass through the vehicle entrance. If it is determined that the vehicle in question located at the vehicle entrance is not the registered vehicle and / or that the person in question is not the registered person, the vehicle in question will not be permitted to pass through the vehicle entrance.
