DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, a headcount management system according to an embodiment will be described with reference to the drawings.

[0012] (Embodiment) (1) Overview A number of people management system 10 according to this embodiment will be described with reference to Fig. 1. The number of people management system 10 manages the number of subjects passing through a collective entrance 220 of a collective facility 200.

[0013] The collective facility 200 is, for example, an apartment building. The collective facility 200 includes a plurality of facilities 210 and a collective entrance 220. When the collective facility 200 is an apartment building, the facilities 210 are dwelling units, and the collective entrance 220 is a common entrance of the collective facility 200. A door 221 is installed at the collective entrance 220. The door 221 is automatically opened and closed by an automatic door device 6 in accordance with the result of face authentication of a subject passing through the collective entrance 220.

[0014] As shown in FIG. 2, the number of people management system 10 includes a first acquisition unit 161, a second acquisition unit 162, and a communication unit 14, 17 (output unit). The first acquisition unit 161 acquires first number of people information on a first number of people, which is the number of people scheduled to pass through the collective entrance 220 of the collective facility 200. The second acquisition unit 162 acquires second number of people information on a second number of people, which is the number of people after the people pass through the collective entrance 220. The above "after the people pass through the collective entrance 220" refers to after the people pass through the collective entrance 220 from the outside to the inside. The communication unit 14, 17 (output unit) transmits (outputs) predetermined information based on the first number of people obtained from the first number of people information acquired by the first acquisition unit 161 and the second number of people obtained from the second number of people information acquired by the second acquisition unit 162.

[0015] According to this configuration, if the first number of people and the second number of people are known, it can be determined whether or not the subjects who passed through the collective entrance 220 include a person who is accompanying them. Since the above-mentioned predetermined information is information based on the first number of people and the second number of people, information on the first number of people and the second number of people can be obtained from the above-mentioned predetermined information. Therefore, it can be determined from the above-mentioned predetermined information whether or not the subjects who passed through the collective entrance 220 include a person who is accompanying them.

[0016] (2) Configuration of intercom system 1, a number of people management system 10 according to this embodiment is provided in, for example, an intercom system 100 for a public facility. The intercom system 100 including the number of people management system 10 will be described below.

[0017] 1, the intercom system 100 is installed in a collective facility 200. The intercom system 100 includes a collective entrance device 1 (also called a lobby intercom handset), a plurality of facility terminals 2 (also called intercom master devices), a control device 3, a face authentication server 4, an imaging device 5, and an alarm device 8.

[0018] (2-1) Configuration of the collective entrance machine The collective entrance device 1 is placed at a predetermined location outside the collective entrance 220 of the collective facility 200. The collective entrance device 1 accepts input of various operations by a person (target person) before passing through the collective entrance 220. The various operations mentioned above include an input operation of the number of people expected to pass through (first number of people) and an input operation of the residence number of the destination. As shown in FIG. 2, the collective entrance device 1 includes an imaging unit 11, an operation unit 12, a communication unit 14, a storage unit 15, a control unit 16, and a communication unit 17.

[0019] The imaging unit 11 captures an image including the face of a person in the vicinity of the front of the collective entrance machine 1. The above-mentioned "person in the vicinity of the front of the collective entrance machine 1" includes, for example, a person who operates the operation unit 12 of the collective entrance machine 1 and a person before passing through the collective entrance 220. Therefore, the image captured by the imaging unit 11 includes the face of the person who operates the operation unit 12 and the face of the person before passing through the collective entrance 220. The image captured by the imaging unit 11 is displayed on the facility terminal 2 of the facility 210 visited by the person, as described later. This allows the residents of the facility 210 visited to confirm the face of the person who is a visitor by video. In addition, the image captured by the imaging unit 11 is used as a face authentication image for face authentication of the person passing through the collective entrance 220, as described later. The image captured by the imaging unit 11 is transmitted from the communication unit 14 to the facility terminal 2 and face authentication server 4 of the facility visited by the person.

[0020] The imaging unit 11 includes an image sensor such as a CMOS (Complementary Metal Oxide Semiconductor) image sensor or a CCD (Charge-Coupled Device) image sensor. In this embodiment, the imaging unit 11 is provided in the collective entrance device 1, but the imaging unit 11 may be provided in a location separate from the collective entrance device 1.

[0021] The operation unit 12 accepts input of operations by a person to the collective entrance device 1. The above operations include an operation for inputting a first number of people, which is the number of people scheduled to pass through the collective entrance 220. The above operations also include an operation for inputting an identification number (e.g., an apartment number) of the facility 210 to be visited. The operation unit 12 has a numeric keypad or the like for inputting the first number of people and the apartment number of the facility 210 to be visited.

[0022] In this embodiment, a person passing through the collective entrance 220 from the outside to the inside inputs, before passing through the collective entrance 220, the number of targets who are scheduled to pass through the collective entrance 220 (a first number of people) and the identification number (e.g., an apartment number) of the facility 210 to be visited, into the operation unit 12. Upon receiving an operation input, the operation unit 12 outputs an operation signal corresponding to the input operation to the control unit 16.

[0023] The communication unit 14 communicates with the control device 3, the face authentication server 4, and the facility terminals 2 provided in the multiple facilities 210 in a wired or wireless manner. The communication unit 14 communicates, for example, using a LAN (Local Area Network), but may also communicate using a WAN (Wide Area Network). The communication unit 14 functions as an output unit that outputs predetermined information based on the first number of people and the second number of people to the control device 3, the face authentication server 4, and the facility terminal 2. The predetermined information can include a determination result of the determination unit 165 described below, and a control signal for causing the alarm device 8 or the facility terminal 2 to output predetermined alarm information.

[0024] The communication unit 17 communicates with the manager terminal 7 by wired or wireless means. Since it is assumed that the manager terminal 7 is located in a place other than the collective facility 200, the communication unit 17 communicates using, for example, a WAN. However, if it is assumed that the manager terminal 7 is located inside the collective facility 200, communication may be performed using the same LAN as the communication unit 14. The communication unit 14 functions as an output unit that outputs predetermined information based on the first number of people and the second number of people to the manager terminal 7. The above-mentioned predetermined information can include the determination result of the determination unit 165 described below, and a control signal for causing the manager terminal 7 to output predetermined notification information.

[0025] The storage unit 15 is a non-volatile storage device (e.g., a hard disk drive (HDD) or a solid state drive (SSD)) for storing various information. The storage unit 15 stores, for example, a program required for the operation of the collective entrance device 1, images captured by the imaging unit 11, operations input to the operation unit 12, received signals and transmitted signals of the communication units 14 and 17, and the like.

[0026] The control unit 16 is configured, for example, with a microcomputer having a processor and a memory. The control unit 16 is realized by a computer system having a processor and a memory. The processor executes an appropriate program, causing the computer system to function as the control unit 16. The program may be pre-recorded in the memory, or may be provided via a telecommunication line such as the Internet, or recorded on a non-transitory recording medium such as a memory card.

[0027] The control unit 16 includes a camera control unit 160, a first acquisition unit 161, a second acquisition unit 162, a third acquisition unit 163, a door control unit 164, a determination unit 165, and a notification control unit 166.

[0028] The camera control unit 160 controls the start and stop of the operation of the imaging unit 11, and outputs the image captured by the imaging unit 11 to the outside (for example, the face authentication server 4) from the communication unit 14. For example, when an operation is input to the operation unit 12, the camera control unit 160 starts the imaging unit 11 and starts capturing an image by the imaging unit 11. Note that in this embodiment, the camera control unit 160 starts the imaging unit 11 using the input of an operation to the operation unit 12 as a trigger. However, a human presence sensor may be provided in the collective entrance device 1, and the imaging unit 11 may be started using the detection of a person within a certain range in front of the collective entrance 220 as a trigger.

[0029] The first acquisition unit 161 acquires first number-of-people information on a first number of people, which is the number of people scheduled to pass through the collective entrance 220. The above phrase "passing through the collective entrance 220" refers to passing through the collective entrance 220 from the outside to the inside. The people are visitors or residents. The visitors are not limited to one person, and may be multiple people.

[0030] More specifically, the first acquisition unit 161 acquires, as the first number-of-people information, the information on the first number of people inputted to the operation unit 12. That is, in this embodiment, when a target person passes through the collective entrance 220, the target person inputs the information on the first number of people to the operation unit 12 before passing through, and the first acquisition unit 161 acquires, as the first number-of-people information, the information on the first number of people inputted to the operation unit 12.

[0031] The second acquisition unit 162 acquires second number-of-people information on a second number-of-people which is the number of the targets after the targets have passed through the assembly entrance 220. That is, the second acquisition unit 162 acquires the second number-of-people information as information for determining whether or not the same number of people (targets) as the first number-of-people obtained from the first number-of-people information acquired by the first acquisition unit 161 have passed through the assembly entrance 220.

[0032] More specifically, the second acquisition unit 162 acquires the second number of people information from the face authentication server 4 via the communication unit 14. As described later, in this embodiment, the imaging device 5 captures an image of a subject after the subject passes through the collective entrance 220. The captured image of the imaging device 5 is then subjected to image processing by the face authentication server 4 to detect a second number of people, which is the number of people appearing in the captured image (i.e., the subjects who passed through the collective entrance 220). The detected information on the second number of people is then transmitted from the face authentication server 4 to the second acquisition unit 162 via the communication unit 14, and is acquired by the second acquisition unit 162 as the second number of people information. In this way, the second acquisition unit 162 acquires the second number of people information based on the captured image of the imaging device 5.

[0033] The third acquisition unit 163 acquires an image including the face of a person (subject) operating the operation unit 12 of the collective entrance device 1, for example, by acquiring an image captured by the imaging unit 11. This acquired image (i.e., the image captured by the imaging unit 11) is used for face authentication when a person passes through the collective entrance 220. The third acquisition unit 163 transmits the acquired image from the communication unit 14 to the face authentication server 4.

[0034] The door control unit 164 controls the opening and closing of the door 221 via the automatic door device 6 based on the authentication result of the face authentication server 4. The automatic door device 6 is a drive device that drives the opening and closing of the door 221 according to the control of the door control unit 164. If the authentication result of the face authentication server 4 is successful (i.e., the person operating the operation unit 12 is a person registered in advance in the face authentication server 4), the door control unit 164 opens the door 221 via the automatic door device 6 for a certain period of time and automatically closes the door after the certain period of time has elapsed. In addition, if the authentication result of the face authentication server 4 is unsuccessful (i.e., the person operating the operation unit 12 is not a person registered in advance in the face authentication server 4), the door control unit 164 does not open the door 221 via the automatic door device 6.

[0035] The determination unit 165 obtains the first number of people information from the first acquisition unit 161, and obtains the second number of people information from the second acquisition unit 162. Then, the determination unit 165 determines whether or not the second number of people obtained from the second number of people information is greater than the first number of people obtained from the first number of people information. If the second number of people is not greater than the first number of people, it means that the subjects who passed through the assembly entrance 220 do not include people who are tailgating. On the other hand, if the second number of people is greater than the first number of people, it means that the subjects who passed through the assembly entrance 220 include people who are tailgating.

[0036] The notification control unit 166 transmits (outputs) specific information, which is information corresponding to the judgment result of the judgment unit 165 (i.e., information based on the first number of people and the second number of people), to the outside (the notification device 8, the manager terminal 7, and the facility terminal 2 at the facility where the subject is visiting) via the communication units 14, 17.

[0037] More specifically, when the determination result of the determination unit 165 is that the second number of people is greater than the first number of people, the notification control unit 166 transmits, as the above-mentioned predetermined information, a control signal for notifying the residents of the facility 210 of the predetermined notification information from the communication unit 14 to the facility terminal 2 of the facility 210 specified by the dwelling number (the identification number of the facility 210 visited by the target person) input to the operation unit 12. The above-mentioned predetermined notification information is information for notifying the target person that a person accompanying the target person is included when the target person passes through the collective entrance 220. The facility terminal 2 that receives the above-mentioned control signal notifies the residents of the facility 210 in which the facility terminal 2 is installed of the above-mentioned predetermined notification information. This makes it possible to notify the residents of the facility 210 visited by the target person that the target person who passed through the collective entrance 220 includes a person accompanying the target person.

[0038] Furthermore, when the determination result of the determination unit 165 is that the second number of people is greater than the first number of people, the notification control unit 166 transmits a control signal from the communication unit 14 to the notification device 8 as the predetermined information for notifying the target person who has passed through the collective entrance 220 (the target person who passes through the area inside the collective entrance 220). This makes it possible to notify the target person who has passed through the collective entrance 220 that the target person includes a person who is tailgating.

[0039] Furthermore, when the determination result of the determination unit 165 is that the second number of people is greater than the first number of people, the notification control unit 166 transmits a control signal from the communication unit 17 to the manager terminal 7 as the above-mentioned predetermined information for notifying the manager who uses the manager terminal 7 of the above-mentioned predetermined notification information. This makes it possible to notify the manager who manages the collective facility 200 that the targets who have passed through the collective entrance 220 include a person who is tailgating.

[0040] (2-2) Facility terminal configuration The facility terminals 2 are arranged in one-to-one correspondence with the facilities 210. The facility terminals 2 display images (visitor's facial images) captured by the imaging unit 11 of the collective entrance device 1, and notify the residents of the facility 210 in which the facility terminals 2 are arranged of the above-mentioned predetermined notification information. The facility terminals 2 include a control unit 21, an operation unit 22, a communication unit 23, a video input unit 24, a display unit 25, and a notification unit 26.

[0041] The control unit 21 is configured, for example, with a microcomputer having a processor and a memory. That is, the control unit 21 is realized by a computer system having a processor and a memory. The processor executes an appropriate program, causing the computer system to function as the control unit 21. The program may be pre-recorded in the memory, or may be provided via a telecommunication line such as the Internet, or recorded on a non-transitory recording medium such as a memory card.

[0042] The operation unit 22 receives input of operations to the facility terminal 2. The operation unit 22 has, for example, an operation button for displaying an image captured by the imaging unit 11 on the display unit 25.

[0043] The communication unit 23 performs wired or wireless communication with the control device 3. The communication unit 23 also performs wired or wireless communication with the collective entrance device 1 and the face authentication server 4 via the control device 3.

[0044] The video input unit 24 inputs the image captured by the imaging unit 11 output from the collective entrance unit 1 via the communication unit 23 .

[0045] The display unit 25 has a thin display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. The display unit 25 displays the captured image (a captured image including the face of the person operating the operation unit 12 of the collective entrance device 1) input to the video input unit 24. This allows the residents of the facility 210 to check the face of a visitor who has come to visit the facility 210 on the display image of the display unit 25.

[0046] When the notification unit 26 receives the control signal from the notification control unit 166 via the communication unit 23 and the control unit 21, it notifies the residents of the facility 210 of the predetermined notification information. The notification unit 26 may be, for example, a sound output device that outputs a sound (voice or electronic sound) corresponding to the content of the notification information, a light emitting device that emits light of a light color corresponding to the content of the notification information, or a display device that displays an image corresponding to the content of the notification information.

[0047] (2-3) Configuration of the control device The control device 3 controls communications between the collective entrance device 1, the multiple facility terminals 2, and the face authentication server 4. To the control device 3, an imaging device 5 and a notification device 8 are connected.

[0048] The imaging device 5 is installed at a predetermined location inside the collective entrance device 1, and captures an image including the face of a person who has passed through an area inside the collective entrance device 1 (i.e., a target person who has passed through the collective entrance 220). More specifically, the imaging device 5 captures an image of a person (target person) who has passed through a predetermined range inside the collective entrance 220 from the time when the door 221 of the collective entrance 220 is opened until a predetermined time (e.g., 30 seconds) has elapsed. At this time, the imaging device 5 captures an image of the target person so that the target person's face is captured. The captured image of the imaging device 5 is transmitted to the face authentication server 4 via the control unit 31 and the communication unit 32 of the control device 3. Then, the face authentication server detects the number (second number of people) of the above-mentioned people (target people who have passed through the collective entrance 220) captured in the captured image. As described above, the second number of people is the number of people who have passed through a predetermined range inside the collective entrance 220 from the time when the door 221 of the collective entrance 220 is opened until a predetermined time has elapsed. Then, information on the detected second number of people is transmitted from the communication unit 32 of the control device 3 to the communication unit 14 of the collective entrance device 1 and acquired by the second acquisition unit 162. The imaging device 5 includes an image sensor such as a CMOS (Complementary Metal Oxide Semiconductor) image sensor or a CCD (Charge-Coupled Device) image sensor.

[0049] The notification device 8 notifies various information to people around the collective entrance 220. More specifically, when the notification device 8 receives the control signal (a control signal for notifying the predetermined notification information) from the notification control unit 166 via the communication unit 32 and the control unit 31, the notification device 8 notifies the predetermined notification information to a target person who has passed through the collective entrance 220. The notification device 8 is installed at a predetermined location inside the collective entrance 220 in order to notify the target person who has passed through the collective entrance 220 of the predetermined notification information. The notification device 8 may be, for example, a sound output device that outputs a sound (voice or electronic sound) corresponding to the content of the notification information, a light emitting device that emits light of a light color corresponding to the content of the notification information, or a display device that displays an image corresponding to the content of the notification information.

[0050] The control device 3 includes a control unit 31 and a communication unit 32 .

[0051] The communication unit 32 performs wired or wireless communication between the collective entrance device 1, the facility terminals 2, and the face authentication server 4. In this embodiment, the communication unit 32 performs communication using, for example, a LAN, but may perform communication using a WAN.

[0052] The control unit 31 is configured, for example, by a microcomputer having a processor and a memory. That is, the control unit 31 is realized by a computer system having a processor and a memory. The processor executes an appropriate program, causing the computer system to function as the control unit 31. The program may be pre-recorded in the memory, or may be provided via a telecommunication line such as the Internet, or recorded on a non-transitory recording medium such as a memory card.

[0053] The control unit 31 controls communications between the collective entrance device 1, the multiple facility terminals 2, and the face authentication server 4. The control unit 31 also controls the imaging device 5 and the notification device 8 to operate as described above.

[0054] (2-4) Face recognition server configuration Based on the captured image of the imaging unit 11 transmitted from the collective entrance device 1, the facial recognition server 4 performs authentication to determine whether the face (the face of the person operating the collective entrance device 1) shown in the captured image matches a facial image registered in the memory unit 43. The facial recognition server 4 also detects the number of people (subjects who have passed through the collective entrance 220) shown in the image captured by the imaging device 5. The facial recognition server 4 includes a facial recognition unit 41, a number-of-people detection unit 44, a communication unit 42, and a memory unit 43.

[0055] The communication unit 42 performs wired or wireless communication between the collective entrance device 1 and the control device 3. The communication unit 42 also performs wired or wireless communication with the facility terminals 2 installed in each of the multiple facilities 210 via the control device 3.

[0056] The storage unit 43 is a non-volatile storage device (e.g., a hard disk drive (HDD) or a solid state drive (SSD)) for storing various information. The storage unit 43 stores, for example, face image data of one or more persons permitted to enter through the collective entrance 220 (e.g., residents of the facility 210 and persons permitted to enter by the residents, etc.).

[0057] The face authentication unit 41 authenticates whether the face appearing in the image captured by the imaging unit 11 is a registered face by comparing the face (the face of the person operating the collective entrance unit 1) appearing in the image captured by the imaging unit 11 and transmitted from the collective entrance unit 1 with the facial image data stored in the memory unit 43. In other words, the face authentication unit 41 authenticates whether the person appearing in the image captured by the imaging unit 11 is a person permitted to pass through the collective entrance 220.

[0058] The face authentication unit 41 transmits the authentication result from the communication unit 42 to the communication unit 14 of the collective entrance machine 1 to have it acquired by the door control unit 164. The authentication result indicates whether or not the authentication is successful. "Authentication is successful" means that the face shown in the image captured by the imaging unit 11 matches the registered face, and "authentication is not successful (i.e. authentication fails)" means that the face shown in the image captured by the imaging unit 11 does not match the registered face.

[0059] The face authentication unit 41 judges whether or not the captured image (captured image showing the subject who passed through the collective entrance 220) transmitted from the imaging device 5 contains a person with the same face as the person (the person who operated the collective entrance device 1) who appears in the captured image (image for authentication) transmitted from the imaging unit 11. If the result of this judgment is that the captured image transmitted from the imaging device 5 contains a person with the same face as the face in the image for authentication, it is confirmed that the captured image transmitted from the imaging device 5 is an image captured by the imaging device 5 of the person (subject) who appears in the image for authentication after the person passed through the collective entrance 220.

[0060] That is, in this embodiment, there is one or more subjects. When the subjects pass through the collective entrance 220, a representative person among the subjects operates the operation unit 12 of the collective entrance device 1 to input the first number of people, and the face of the representative person at this time is captured by the imaging unit 11, and facial authentication is performed based on the captured image. Then, when the representative person is successful in the facial authentication, the door 221 of the collective entrance 220 is automatically opened, and all the subjects including the representative person pass through the collective entrance 220. In order to detect the number of the subjects who have passed (the second number of people), the imaging device 5 captures an image of the subjects who have passed. For this reason, the facial authentication unit 41 checks whether the face of the representative person (subject person) who has undergone facial authentication is captured in the image captured by the imaging device 5 or not, by the above-mentioned judgment.

[0061] If the captured image transmitted from the imaging device 5 does not show a person with the same face as the face shown in the authentication image, the face authentication unit 41 performs the above-mentioned determination again using another captured image transmitted from the imaging device 5. The other captured image transmitted from the imaging device 5 is, for example, a captured image transmitted from the imaging device 5 that is captured chronologically before or after the captured image previously transmitted. That is, the imaging device 5 captures a plurality of captured images with a time difference therebetween, and transmits the plurality of captured images to the face authentication server 4. The face authentication server 4 performs the above-mentioned determination by the face authentication unit 41 using one of the plurality of captured images. Then, if the face of the representative who has received the authentication image is not shown in the captured image of the imaging device 5 as a result of the determination by the face authentication unit 41, the face authentication server 4 performs the above-mentioned determination by the face authentication unit 41 again using another captured image of the plurality of captured images transmitted from the imaging device 5. The captured image of the imaging device 5 captures the subjects including the representative who has received the face authentication after they have passed through the assembly entrance 220. Therefore, by replacing the captured image of the imaging device 5 and repeatedly performing the above judgment by the face authentication unit 41, it is possible to always confirm through the above judgment that the face of the representative (subject) who has undergone face authentication is captured in the captured image of the imaging device 5.

[0062] If the result of the above determination by the face authentication unit 41 is that the image captured by the imaging device 5 includes a person whose face is the same as the face captured in the image for face authentication (the image captured by the imaging unit 11), the number of people detection unit 44 detects the number of people (subjects) captured in the image captured by the imaging device 5 (the second number of people), based on the image captured by the imaging device 5. Then, the number of people detection unit 44 transmits the detection result (information on the second number of people) from the communication unit 42 to the communication unit 14 of the collective entrance device 1, and causes the second acquisition unit 162 to acquire it as second number of people information.

[0063] (2-5) Configuration of the People Management System 10 The number of people management system 10 of this embodiment includes at least the above-mentioned first acquisition unit 161, second acquisition unit 162, third acquisition unit 163, door control unit 164, notification control unit 166, communication units 14, 17, face authentication unit 41, and number of people detection unit 44. In this embodiment, most of the components of the number of people management system 10 (first acquisition unit 161, second acquisition unit 162, third acquisition unit 163, door control unit 164, notification control unit 166) are housed in the collective entrance device 1. The remaining components of the number of people management system 10 (face authentication unit 41 and number of people detection unit 44) are distributed and arranged in other components of the intercom system 100 (for example, face authentication server 4).

[0064] (2-6) Operation Description The operation of the headcount management system 10 will be described with reference to FIG.

[0065] Before passing through the collective entrance 220, a person (target person) who is going to pass through the collective entrance 220 inputs information on the number of targets (first number of people) who are going to pass through the collective entrance 220 and identification information (e.g., a dwelling unit number) of the facility 210 to be visited into the operation unit 12 of the collective entrance device 1 (step S1). Then, the first acquisition unit 161 acquires the information on the first number of people input into the operation unit 12 as first number of people information (step S2).

[0066] Then, the imaging unit 11 of the collective entrance device 1, for example, triggered by an operation input to the operation unit 12, captures an image (image for facial recognition) including the face of the person operating the operation unit 12 (representative of the subjects), and transmits the captured image to the facial recognition server 4 (step S3).

[0067] Then, the face authentication unit 41 of the face authentication server 4 performs authentication (e.g., face authentication) to determine whether the person operating the operation unit 12 is a registered person, based on the captured image (image captured by the imaging unit 11) received from the collective entrance device 1. If the authentication is successful, the face authentication server 4 transmits the authentication result from the communication unit 42 to the communication unit 14 of the collective entrance device 1, and causes the door control unit 164 to acquire it. If the door control unit 164 receives the authentication result indicating that the authentication was successful from the face authentication server 4, it opens the door 221 of the collective entrance device 220 for a certain period of time (step S4).

[0068] When the door 221 of the collective entrance 220 is opened, the subject passes through the collective entrance 220 (step S5). When the subject passes through the collective entrance 220, the imaging device 5 captures an image of the subject after passing through the collective entrance 220, including the subject's face, and transmits the captured image to the face authentication server 4 (step S6). The face authentication unit 41 of the face authentication server 4 judges whether or not a person with the same face as the face appearing in the authentication image is captured in the image captured by the imaging device 5 (step S7). If the result of this judgment is that a person with the same face as the face appearing in the face authentication image is not captured in the image captured by the imaging device 5 (No in step S7), the face authentication unit 41 changes the captured image used in the above judgment to another captured image of the imaging device 5 (step S8), and performs the above judgment again (step S7).

[0069] Then, if the result of the above determination is that the image captured by the imaging device 5 contains a person with the same face as that in the face authentication image (Yes in step S7), the number of people detection unit 44 of the face authentication server 4 detects a second number of people, which is the number of people (subjects) appearing in the captured image, based on the captured image by the imaging device 5 (i.e., a captured image containing a person with the same face as that in the face authentication image). Then, the number of people detection unit 44 transmits the detection result from the communication unit 42 to the communication unit 14 of the collective entrance device 1 to cause the second acquisition unit 162 to acquire it. The second acquisition unit 162 acquires the detection result (information on the second number of people) transmitted from the number of people detection unit 44 as second number of people information (step S9).

[0070] Then, the determination unit 165 determines whether the second number of people is greater than the first number of people based on the first number of people information acquired by the first acquisition unit 161 and the second number of people information acquired by the second acquisition unit 162 (step S10). If the result of this determination is that the second number of people is not greater than the first number of people (No in step S10), the determination unit 165 determines that there is no tailgating (i.e., the subjects who passed through the assembly entrance 220 do not include people who are tailgating) (step S11). Then, the process ends.

[0071] Also, when the second number of people is greater than the first number of people as a result of the judgment in step S10 (Yes in step S10), the judgment unit 165 judges that there is tailgating (i.e., the subjects who passed through the collective entrance 220 include a person who is tailgating) (step S12). In this case, the notification control unit 166 transmits a control signal from the communication unit 14 to the facility terminal 2 of the facility 210 visited by the subject (i.e., the facility 210 with the dwelling unit number input to the operation unit 12 in step S1) to notify the residents of the facility 210 visited of predetermined notification information. The predetermined notification information is, for example, information notifying that the subjects who passed through the collective entrance 220 include a person who is tailgating. Then, when the facility terminal 2 of the facility 210 visited receives the control signal from the notification control unit 166, it notifies the residents of the facility 210 visited of the predetermined notification information (step S13).

[0072] Furthermore, the notification control unit 166 transmits a control signal from the communication unit 17 to the manager terminal 7 used by the manager of the collective facility 200, for notifying the manager of the predetermined notification information. Then, upon receiving the control signal from the notification control unit 166, the manager terminal 7 notifies the manager of the predetermined notification information (step S14).

[0073] The notification control unit 166 also transmits a control signal from the communication unit 14 to the notification device 8 for notifying the target person who has passed through the collective entrance 220 of the above-mentioned predetermined notification information. Then, upon receiving the above-mentioned control signal from the notification control unit 166, the notification device 8 notifies the target person who has passed through the collective entrance 220 of the above-mentioned predetermined notification information (step S15). Then, the process ends.

[0074] (2-7) Effects The number of people management system 10 according to the embodiment includes a first acquisition unit 161, a second acquisition unit 162, and communication units 14, 17 (output units). The first acquisition unit 161 acquires first number of people information on a first number of people, which is the number of people scheduled to pass through the collective entrance 220 of the collective facility 200. The second acquisition unit 162 acquires second number of people information on a second number of people, which is the number of people after the people have passed through the collective entrance 220. The communication units 14, 17 transmit (output) predetermined information based on the first number of people and the second number of people.

[0075] According to this configuration, if the first number of people and the second number of people are known, it can be determined whether or not the subjects who passed through the collective entrance 220 include a person who is accompanying them. Since the above-mentioned predetermined information is information based on the first number of people and the second number of people, information on the first number of people and the second number of people can be obtained from the above-mentioned predetermined information. Therefore, it can be determined from the above-mentioned predetermined information whether or not the subjects who passed through the collective entrance 220 include a person who is accompanying them.

[0076] In the number of people management system 10, a collective entrance device 1 of the intercom system 100 provided in the collective facility 200 is installed outside the collective entrance 220. The collective entrance device 1 includes an operation unit 12 that receives an operation by a target person to input a first number of people. The first acquisition unit 161 acquires first number of people information based on the first number of people input to the operation unit 12.

[0077] According to this configuration, the first number of people can be input from the collective entrance device 1. That is, the first number of people can be input to the number-of-people management system 10 with a simple configuration.

[0078] In the number of people management system 10, the imaging device 5 is connected to the intercom system 100 provided in the collective facility 200. The second acquisition unit 162 acquires second number of people information via the intercom system 100.

[0079] According to this configuration, the imaging device 5 can be connected to the number of people management system 10 by using the intercom system 100. This allows the imaging device 5 to be connected to the number of people management system 10 relatively easily.

[0080] In the number-of-persons management system 10, the second number of people is the number of subjects who pass through a predetermined range inside the collective entrance 220 from when the collective entrance 220 is opened until a predetermined time has elapsed.

[0081] According to this configuration, the second acquisition section 162 can efficiently acquire the second number of people information.

[0082] Furthermore, in the number of people management system 10, the target persons include one or more people. The number of people management system 10 includes a third acquisition unit 163, a face authentication unit 41, and a door control unit 164. The third acquisition unit 163 acquires image information regarding an image including the face of a representative person among the target persons before passing through the collective entrance 220. The face authentication unit 41 authenticates the face of the representative person based on the image information acquired by the third acquisition unit 163. The door control unit 164 unlocks an electronic lock on a door provided at the collective entrance 220 when the face authentication unit 41 succeeds in authenticating the face of the representative person.

[0083] According to this configuration, if the authentication of a representative of the targets is successful, the targets can pass through the assembly entrance 220.

[0084] In the number of people management system 10, an imaging device 5 is installed in the collective facility 200 to capture images of subjects passing through an area inside the collective entrance 220. When the face authentication unit 41 succeeds in authenticating the representative, the second acquisition unit 162 acquires second number of people information based on an image captured by the imaging device 5 that includes a person with the same face as the representative.

[0085] According to this configuration, in a collective facility 200 where the electronic lock of the collective entrance 220 is automatically unlocked by face recognition of the representative of the subjects, it is possible to determine whether the subjects who have passed through the collective entrance 220 include a person accompanying them.

[0086] Moreover, in the number of people management system 10, the collective facility 200 has a plurality of facilities 210. A plurality of facility terminals 2 of the intercom system 100 provided in the collective facility 200 are installed in the plurality of facilities 210 so as to correspond to the plurality of facilities 210. A collective entrance device 1 of the intercom system 100 is installed outside the collective entrance 220. The collective entrance device 1 has an operation unit 12 that receives an operation to input identification information of the facility 210 to be visited by the target person. When the second number of people is greater than the first number of people, the communication unit 14 (output unit) transmits (outputs) a control signal for notifying the facility terminal 2 of the facility 210 specified by the identification information input to the operation unit 12 of the predetermined information, as the above-mentioned predetermined information.

[0087] According to this configuration, when the second number of people is greater than the first number of people, it is possible to notify residents of facility 210 visited by the target person that the target people who have passed through assembly entrance 220 include a person accompanying the target person.

[0088] The number of people management system 10 also includes an alarm device 8 installed at a predetermined location inside the collective entrance 220. When the second number of people is greater than the first number of people, the communication unit 14 (output unit) transmits (outputs) a control signal to the alarm device 8 as the predetermined information, for notifying the target person who has passed through the collective entrance 220 of predetermined alarm information.

[0089] According to this configuration, when the second number of people is greater than the first number of people, it is possible to notify the targets who have passed through the assembly entrance 220 that a person accompanying them is included.

[0090] In addition, when the second number of people is greater than the first number of people, the number of people management system 10 causes the communication unit 17 (output unit) to transmit (output) a control signal to the manager terminal 7 used by the manager who manages the collective facility 200, as the above-mentioned specified information, in order to notify the manager of specified notification information.

[0091] According to this configuration, when the second number of people is greater than the first number of people, it is possible to notify the manager of collective facility 200 that the targets who have passed through collective entrance 220 include people who are accompanying others.

[0092] (2-8) Forms other than headcount management systems The same function as the headcount management system 10 may be embodied in a headcount management method, a (computer) program, or a non-transitory recording medium.

[0093] A number-of-people management method according to one embodiment includes a first acquisition step, a second acquisition step, and an output step. In the first acquisition step, first number-of-people information on a first number of people, which is the number of people scheduled to pass through a collective entrance of a collective facility, is acquired. In the second acquisition step, second number-of-people information on a second number of people, which is the number of people after the people have passed through the collective entrance, is acquired. In the output step, predetermined information based on the first number of people and the second number of people is output.

[0094] A (computer) program according to one aspect is a program for causing one or more processors to execute the headcount management method.

[0095] A non-transitory recording medium according to one embodiment is a non-transitory recording medium having the above program recorded thereon.

[0096] (2-9) Variations The above embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. Below, modifications of the above embodiment are listed. The modifications described below can be applied in appropriate combination.

[0097] (2-9-1) Variation 1 In the above embodiment, the target person inputs the number of targets who are scheduled to pass through (first number of targets) into the operation unit 12, and the first acquisition unit 161 acquires the information on the first number of targets input into the operation unit 12 as first number of target information. In contrast, in the first modification, as shown in Fig. 4, the collective entrance device 1 includes a wireless communication unit 18 that receives wireless signals transmitted from mobile terminals 19 carried by the target people. The first acquisition unit 161 of the first modification acquires the first number of target information based on the wireless signals received by the wireless communication unit 18.

[0098] More specifically, the collective entrance device 1 of the first modification includes a wireless communication unit 18 in the collective entrance device 1 of the above embodiment. The wireless communication unit 18 communicates with a mobile terminal 19 carried by a target person passing through the collective entrance 220 using short-range wireless communication (e.g., Bluetooth (registered trademark) Low Energy). The mobile terminal 19 is, for example, a smartphone or a tablet terminal, and is a communication terminal that can be carried by the target person. The wireless communication unit 18 transmits a short-range wireless signal (e.g., a beacon signal) at regular time intervals limited to a predetermined area outside the collective entrance 220. The short-range wireless signal includes a control command to cause the wireless communication unit 18 to return a response signal together with identification information of the mobile terminal that received the short-range wireless signal.

[0099] The portable terminal 19 of the subject has a wireless communication function for performing the short-range wireless communication with the wireless communication unit 18. The portable terminal 19 of the subject has a program (application) pre-installed therein, which operates to return identification information of the portable terminal itself and the response signal when the portable terminal 19 receives the control command.

[0100] The operation of the first modified example will be described with reference to Fig. 5. In the example of Fig. 5, the operation will be described taking as an example a case where there is one target person (that is, a case where there is one mobile terminal 19).

[0101] The wireless communication unit 18 of the collective entrance device 1 transmits a short-range wireless signal within a predetermined area outside the collective entrance device 220 (step S20). When the target person enters the predetermined area outside the collective entrance device 220, the target person's mobile terminal 19 receives the short-range wireless signal from the wireless communication unit 18 of the collective entrance device 1 (step S21). The mobile terminal 19 then returns a response signal together with its own identification information to the wireless communication unit 18 (step S22). The wireless communication unit 18 then receives the response signal and the identification information from the target person's mobile terminal 19 (step S23). The wireless communication unit 18 outputs the received response signal and identification information to the first acquisition unit 161 (step S24). The first acquisition unit 161 receives the response signal and the identification signal from the wireless communication unit 18. (Step S25). Then, the first acquisition unit 161 detects the number of subjects based on the input response signals and identification information (Step S26). That is, the first acquisition unit 161 detects the number of subjects by detecting the number of pairs of response signals and identification information. Then, the first acquisition unit 161 acquires information on the detected number of people (first number of people) as first number of people information (Step S27).

[0102] In the first modification, the above application is installed in the portable terminal 19 of the target person in advance, and therefore the response signal and the identification information can be returned when the above control command is received. The above application is not installed in the portable terminal of the person accompanying the target person in advance, and therefore even if the person accompanying the target person enters the above specified area, the portable terminal of the person accompanying the target person does not transmit the response signal and the identification information back to the wireless communication unit 18. Therefore, the first number of people information acquired by the first acquisition unit 161 is a number of people that does not include the number of people accompanying the target person.

[0103] According to the first modification, the first acquisition unit 161 can acquire the first number of people information by utilizing communication between the collection entrance device 1 and the mobile terminal 19 carried by the target person.

[0104] In the first modification, the wireless communication unit 18 is provided in the collective entrance unit 1, but the wireless communication unit 18 may be provided in a location away from the collective entrance unit 1.

[0105] (2-9-2) Variation 2 In the above embodiment, the subject inputs the number of subjects (first number of people) who are scheduled to pass through to the operation unit 12, and the first acquisition unit 161 acquires the information on the first number of people input to the operation unit 12 as the first number of people information. In contrast, in the second modification, as shown in FIG. 1, when the information on the first number of people is input to a facility terminal 2 installed in a certain facility 210 among a plurality of facilities 210, the first acquisition unit 161 acquires the first number of people information based on the information on the first number of people input to the certain facility terminal 2. That is, in the second modification, a resident of the facility 210 visited by the subject can input the information on the first number of people from the operation unit 22 of the facility terminal 2. The second modification will be described in more detail below.

[0106] As shown in FIG. 1, the number of people management system 10 according to the second modification is configured similarly to the number of people management system 10 according to the above embodiment.

[0107] In the second modification, a resident of the facility 210 visited by the subject uses the operation unit 22 of the facility terminal 2 to store the number of subjects (first number of people) scheduled to pass through the collective entrance 220 before the subject arrives in the memory unit 43 of the face authentication server 4 in association with the image data for face authentication of the subjects. When the face authentication unit 41 of the second modification performs face authentication of the subject based on the captured image of the imaging unit 11, the face authentication unit 41 reads out information on the first number of people associated with the image data for face authentication used in the face authentication from the memory unit 43. Then, the face authentication unit 41 transmits the read information on the first number of people from the communication unit 42 of the face authentication server 4 to the communication unit 14 of the collective entrance device 1, and causes the first acquisition unit 161 to acquire the information. The first acquisition unit 161 acquires the information on the first number of people transmitted from the face authentication unit 41 as the first number of people information.

[0108] According to the second modification, a resident of a destination visited by the subject can input the first number of people using facility terminal 2 provided in each facility 210.

[0109] (2-9-3) Variation 3 In the above embodiment, the imaging device 5 is connected to the control device 3 of the intercom system 100 (i.e., the imaging device 5 is connected via the intercom system 100) as an example. In the third modification, the imaging device 5 is connected directly to the collective entrance device 1 (i.e., the number of people control system 10) (i.e., the imaging device 5 is connected without going through the intercom system 100) as an example.

[0110] As shown in FIG. 6, in the third modification, the imaging device 5 is connected to the collective entrance machine 1 (i.e., the number of people management system 10). In the third modification, the image captured by the imaging device 5 is transmitted to the face authentication server 4 via the control unit 16 and the communication unit 14. As in the above embodiment, the face authentication server 4 detects the second number of people from the image captured by the imaging device 5, and transmits the detected information on the second number of people from the communication unit 42 to the second acquisition unit 162 of the collective entrance machine 1. The second acquisition unit 162 acquires the information on the second number of people transmitted from the face authentication server 4 as second number of people information. In other words, the second acquisition unit 162 acquires the second number of people information based on the image captured by the imaging device 5.

[0111] According to the third modification, the information on the first number of people can be input from the facility terminal 2. This allows a resident of facility 210 to input the information on the first number of people in advance using the facility terminal 2.

[0112] (2-9-4) Variation 4 In the above embodiment, the door 221 of the common entrance 220 is automatically opened for a certain period of time when the face authentication of the person (subject) operating the operation unit 12 is successful. However, the door 221 may be opened for a certain period of time when a PIN code for unlocking the electronic lock of the door 221 is input to the operation unit 12 of the common entrance device 1. In this case, when the input of the PIN code is adopted instead of face authentication, the face authentication unit 41 is omitted in the face authentication server 4, and the face authentication process is omitted. Also, in this case, the number of people detection unit 44 does not judge whether or not a person with the same face as the face appearing in the face authentication image appears in the image captured by the imaging device 5, but detects the second number of people based on the image captured by the imaging device 5.

[0113] (2-9-5) Variation 5 In this embodiment, the number of people control system 10 is illustrated as being distributed among the components of the intercom system 100. However, the number of people control system 10 may be housed and disposed within a single housing. The number of people control system 10 may also be distributed and disposed in a server or the like outside the intercom system 100 via a communication network (e.g., a WAN).

[0114] (2-9-6) Variation 6 In the above embodiment, it is assumed that all the subjects who are scheduled to pass through the collective entrance 220 pass through the collective entrance 220 together. In contrast, in the sixth modified example, a case is illustrated in which the subjects who are scheduled to pass through the collective entrance 220 come separately and pass through the collective entrance 220 separately. For example, it is assumed that the number of subjects is five, and two subjects of the five subjects come first and pass through the collective entrance 220 first, and the remaining three subjects come later and pass through the collective entrance 220. In this case, the subjects input the first number of people into the operation unit 12 of the collective entrance device 1 before passing through the collective entrance 220. Therefore, when the two subjects who came first pass through the collective entrance 220, one of the two subjects inputs the first number of people, which is the number of people who came first, into the operation unit 12 as the first number of people, instead of the initial number of people, which is five, and the two who came first pass through the collective entrance 220. Then, the remaining three subjects who arrived later are input as the first number of people into operation unit 12, not as the initial number of subjects, which was five, but as the number of people who arrived later, and the three who arrived later pass through collective entrance 220. In other words, if subjects who are scheduled to pass through collective entrance 220 arrive separately, those who arrived at the same time pass through collective entrance 220 together. At that time, as the first number of people to be input into operation unit 12, the number of people who arrive at the same time and pass through together is input into operation unit 12 as the first number of people.

[0115] Although the sixth modification is based on the above embodiment, the first modification may also be used as a premise.

[0116] (2-9-7) Variation 7 Variation 6 is based on the above embodiment, while Variation 7 is based on Variation 2. That is, Variation 7 illustrates a case in Variation 2 where subjects scheduled to pass through collective entrance 220 arrive separately and pass through collective entrance 220 separately. For example, assume that there are five subjects, and two of the five subjects arrive first and pass through collective entrance 220 first, and the remaining three subjects arrive later and pass through collective entrance 220.

[0117] In the seventh modification, similarly to the second modification, the resident inputs information on the first number of people from the operation unit 22 of the facility terminal 2. Therefore, when the two targets who arrived first pass through the collective entrance 220, the second number of people (three people), which is the number of people who passed through the collective entrance 220, is less than the first number of people (five people) input by the resident from the operation unit 22. That is, the determination unit 165 determines that the second number of people is less than the first number of people. In this case, the notification control unit 166 notifies the resident via the communication unit 14 and the facility terminal 2 of the resident of an inquiry as to whether or not to input the difference obtained by subtracting the second number of people from the first number of people (the number of remaining targets who may arrive later (three people)) as the first number of people into the operation unit 22 in addition to the first number of people (five people) already input.

[0118] Then, if the remaining targets arrive later, the resident inputs the difference as the first number of people into the operation unit 22. As a result, if the remaining targets (3 people) arrive later, they can pass through the collective entrance 220 in the procedure of the second modification. In the seventh modification as well, if the second number of people is less than the first number of people as described above, the second number of people is not greater than the first number of people, so it is determined that there are no tailgated people, as in the second modification. The notification control unit 166 may automatically set the information on the first number of people relative to the difference, omitting the notification by the inquiry.

[0119] According to the sixth modification, even if subjects who are scheduled to pass through the collective entrance 220 arrive separately and pass through the collective entrance 220 separately, tailgating can be determined.

[0120] (2-9-8) Variation 8 In the eighth modification, in the second modification, when the second number of people is smaller than the first number of people, the notification control unit 166 notifies the resident that the second number of people is smaller than the first number of people and the information on the second number of people via the communication unit 14 and the facility terminal 2 of the resident. At this time, the notification control unit 166 notifies the resident of an inquiry about whether or not the already inputted first information needs to be changed via the facility terminal 2 of the resident. When the resident knows that the already inputted first number of people needs to be changed in response to the inquiry (for example, when the resident knows that the number of people scheduled to pass through the collective entrance 220 is smaller than the initial number of people), the resident inputs the latest first number of people for the already inputted first number of people from the operation unit 22 of the facility terminal 2 of the resident. As a result, the already inputted first number of people is changed to the latest first number of people. When the latest information on the first number of people is input to the operation unit 22, the latest information on the first number of people is transmitted to the control unit 16 and acquired by the first acquisition unit 161.

[0121] Then, the determination unit 165 re-determines whether the second number of people is greater than the first number of people based on the latest first information acquired by the first acquisition unit 161. If the re-determination result shows that the second number of people is greater than the first number of people, the determination unit 165 determines that tailgating is present. After it is determined that tailgating is present, the same processing as in Modification 2 is performed. If the re-determination result shows that the second number of people is less than the first number of people, the processing of Modification 8 is performed again. If the re-determination result shows that the first number of people and the second number of people are the same, the determination unit 165 determines that tailgating is not present. After it is determined that tailgating is not present, the same processing as in Modification 2 is performed.

[0122] The determination result (predetermined information) of the re-determination by determination unit 165 is re-transmitted from communication unit 14 to the control device 3 and facility terminal 2. Furthermore, in accordance with the determination result of re-determination by determination unit 165, a control signal (predetermined information) for causing the alarm device 8 or the facility terminal 2 to output the predetermined alarm information is re-transmitted from communication unit 14 to the alarm device 8 or the facility terminal 2.

[0123] According to the eighth modification, when the second number of people is smaller than the first number of people, it is possible to more accurately determine whether or not there is a tailgating.

[0124] (Aspect) As is apparent from the above-described embodiment and modified examples, the present specification discloses the following aspects.

[0125] The number of people management system (10) according to the first aspect includes a first acquisition unit (161), a second acquisition unit (162), and an output unit (14, 17). The first acquisition unit (161) acquires first number of people information on a first number of people, which is the number of people scheduled to pass through a collective entrance (220) of a collective facility (200). The second acquisition unit (162) acquires second number of people information on a second number of people, which is the number of people after passing through the collective entrance (220). The output unit (14, 17) outputs predetermined information based on the first number of people and the second number of people.

[0126] According to this configuration, if the first number of people and the second number of people are known, it can be determined whether or not the subjects who passed through the collective entrance (220) include a person who is accompanying them. Since the predetermined information is based on the first number of people and the second number of people, information on the first number of people and the second number of people can be obtained from the predetermined information. Therefore, it can be determined from the predetermined information whether or not the subjects who passed through the collective entrance (220) include a person who is accompanying them.

[0127] In the first embodiment of the number-of-people management system (10) according to the second aspect, a group entrance device (1) of an intercom system (100) provided in a group facility (200) is installed outside a group entrance (220). The group entrance device (1) accepts an operation to input a first number of people. A first acquisition unit (161) acquires first number-of-people information based on the first number of people input to the group entrance device (1).

[0128] According to this configuration, for example, the first number of people can be input by the target person from the collective entrance device (1). That is, the first number of people can be input to the number-of-people management system (10) with a simple configuration.

[0129] In the first embodiment of the number of people management system (10) according to the third aspect, a group entrance device (1) of an intercom system (100) provided in a group facility (200) is installed outside a group entrance (220). The group entrance device (1) includes a wireless communication unit (18) that receives wireless signals transmitted from communication terminals (19) carried by the target persons. A first acquisition unit (161) acquires first number of people information based on the wireless signals received by the wireless communication unit (18).

The plurality of facility terminals (2) accept input of a first number of people. When the first number of people is input to a facility terminal (2) installed in a certain facility (210) among the plurality of facilities (210), a first acquisition unit (161) acquires first number of people information based on the first number of people input to the facility terminal (2) installed in the certain facility (210).

[0132] According to this configuration, the first number of people can be input from the facility terminal 2. This allows a resident of the facility 210 to input the first number of people in advance using the facility terminal 2.

[0133] In the fifth aspect of the headcount management system (10), in the fourth aspect, when the second number of people is less than the first number of people, the output unit (14) notifies the facility terminal (2) of the certain facility of an inquiry as to whether or not to input the difference obtained by subtracting the second number of people from the first number of people as the first number of people into the facility terminal (2) of the certain facility.

[0134] According to this configuration, the resident of the certain facility (210) can decide whether or not to input the difference as the first number of people into the facility terminal (2) by the inquiry. Then, if the difference is input as the first number of people into the facility terminal (2), it can be determined whether or not the person of the difference has an accompaniment.

[0135] In the sixth aspect of the headcount management system (10), in the fourth or fifth aspect, when the second number of people is less than the first number of people, the output unit (14) sends an inquiry to the facility terminal (2) of the certain facility as to whether or not the already input first number of people needs to be changed.

[0136] According to this configuration, the resident of the certain facility (210) can determine, through the inquiry, whether or not it is necessary to change the first number of people that has already been input.

[0137] In the seventh aspect of the number of people management system (10), in the sixth aspect, when latest first number of people information for a first number of people that has already been input is input to the facility terminal (2) of the certain facility (210), the first acquisition unit (161) re-acquires the first number of people information based on the latest first number of people input to the facility terminal (2), and the output unit (14) re-outputs the specified information based on the latest first number of people.

[0138] According to this configuration, when the second number of people is smaller than the first number of people, it is possible to more accurately determine whether or not there is a tailgating.

[0139] In the first aspect of the number of people management system (10) according to the eighth aspect, an imaging device (5) is installed in a collective facility (200) for imaging targets passing through an area inside a collective entrance (220).
