[0001] The present disclosure relates to a photographing unit, an information processing device, a traffic management system, an information processing method, and a recording medium.

[0002] It is known that face recognition is used in traffic management systems.

[0003] For example, Patent Document 1 discloses a passage management system that includes an information processing device that uses a camera to capture an image of a range including the face of a person entering a gate and performs face recognition processing on the captured image.

[0004] Japanese Patent Application Publication No. 2023-75227

[0005] The traffic management system disclosed in Patent Document 1 uses a camera to capture an image of a person entering a gate within a certain range, including the face of the person, and performs facial recognition processing on the captured image to manage the person's passage through the gate. However, it can be difficult for a user to grasp the camera's position when entering the gate, which can lead to the user looking in a direction that the traffic management system does not anticipate.

[0006] An object of the present disclosure is to provide a photographing unit, an information processing device, a traffic management system, an information processing method, and a recording medium that solve the above-mentioned problems.

[0013] Hereinafter, each embodiment of the present disclosure will be described with reference to the drawings. Note that the drawings and specific configurations used in each embodiment should not be used to interpret the disclosure. The same or corresponding configurations in all drawings are denoted by the same reference numerals, and common descriptions will be omitted. Note that in this disclosure, the drawings relate to one or more embodiments.

[0014] First Embodiment An embodiment of the present disclosure will now be described with reference to the drawings. An example of the configuration of an imaging unit, an information processing device, and a traffic management system according to the present disclosure will be described with reference to FIGS. 1 to 11.

[0015] (Configuration of the Passage Management System) The passage management system 10 is used to perform face recognition processing on a facial image of a user U and manage the passage of the user U through a gate 1. As shown in FIG. 1 , the passage management system 10 includes a gate 1, a photographing unit 2, and an information processing device 5.

[0016] (Gate Configuration) The gate 1 uses an openable / closable door 11 to manage the passage of a user U. As shown in FIGS. 1 to 3 , the gate 1 includes a door 11 and a guide member 12. The door 11 opens and closes based on the results of authentication of a facial image of the entering user U. Note that the open / closed state of the door 11 does not matter while waiting for authentication. The guide member 12 is provided with a door 11. For example, in the present disclosure, it is assumed that each guide member 12 (first guide member 12R, second guide member 12L) is provided with a door 11. For example, the gate 1 may include a first guide member 12R and a second guide member 12L as the guide members 12. The first guide member 12R and the second guide member 12L face each other. A lane L through which the user U can pass is formed between the first guide member 12R and the second guide member 12L. In the present disclosure, it is assumed that one gate forms one lane. The first guide member 12R includes a photographing unit 2 as a first photographing unit 2ENT, and the second guide member 12L includes a photographing unit 2 as a second photographing unit 2END. In this disclosure, for simplicity of explanation, it is assumed that the user U passes through the gate 1 in one direction D. In other words, it is assumed that the user U enters through the entrance / exit E1 of the gate 1 and exits through the entrance / exit E2 of the gate 1. Furthermore, when the user U enters through the entrance / exit E2 of the gate 1 and exits through the entrance / exit E1 of the gate 1, the direction opposite to the direction D is referred to as the direction RD. For example, the gate 1 may allow people to pass in both directions. Furthermore, in this disclosure, for simplicity of explanation, it is assumed that when the user U passes through the gate 1 in one direction D, the first guide member 12R is located on the right side of the user U, and the second guide member 12L is located on the left side of the user U. The height of each guide member 12 (first guide member 12R, second guide member 12L) is set so that the photographing units 2 (first photographing unit 2ENT, second photographing unit 2END) can capture a facial image of the user U. As an example, the height of each guide member 12 (first guide member 12R, second guide member 12L) is set to be equal to or lower than the position of the face of the user U, but is not limited to this.

[0017] (Configuration of the Camera Unit) The camera unit 2 captures a facial image of a user U entering the gate 1. The camera unit 2 includes a camera 21, a housing 22, and a light-emitting member 23. The camera 21 is provided at the gate 1. The housing 22 is attached to the guide member 12 and stores the camera 21. In other words, the camera 21 is attached to the gate 1 via the housing 22. For example, in the present disclosure, two cameras 21 (camera 21ENT, camera 21END) are provided at each guide member 12 (first guide member 12R, second guide member 12L). The camera 21ENT included in the first camera unit 2ENT is provided at the first guide member 12R, and the camera 21END included in the second camera unit 2END is provided at the second guide member 12L. The light-emitting member 23 is located at least partially around the camera 21 and is capable of emitting light depending on the authentication status of the facial image. There are four authentication states: authentication standby, authentication in progress, authentication success, and authentication failure. The optical axis of the light emitting member 23 is directed toward the center of the housing 22.

[0018] (Position of the Camera Unit) As shown in FIG. 1 again, the camera 21ENT provided on the first guide member 12R is located at position ENT, which is closer to the entrance / exit E2 than the center of the guide member 12. From position ENT, the camera 21ENT photographs the user U entering the gate 1 from the entrance / exit E1 in direction D. For example, in the present disclosure, the camera 21ENT stored in the housing 22 is installed at a position where it can photograph the user U from in front of the user U entering the gate 1 from the entrance / exit E1 in direction D. For example, as shown in FIG. 3, the camera 21ENT photographs the user U from the right front of the user U. Note that the camera 21ENT may also photograph the user U from the left front of the user U. The camera 21END provided on the second guide member 12L is located at position END, which is closer to the entrance / exit E1 than the center of the guide member 12. The camera 21END photographs a user (hereinafter referred to as "user X") from position END as he enters gate 1 from entrance / exit E2 in the RD direction. For example, in the present disclosure, the camera 21END stored in the housing 22 is installed in a position where it can photograph the user from in front of the user X as he enters gate 1 from entrance / exit E2 in the RD direction. For example, the camera 21END photographs the user X from the right front of the user X as he enters gate 1 from entrance / exit E2 in the RD direction. Note that the camera 21END may also photograph the user X from the left front of the user X. From the above, the facing direction of the camera 21 in the present disclosure is tilted toward the user U (user X) entering gate 1 with respect to the extension direction of the gate 1.

[0019] 4 and subsequent figures, the guide member 12 will be referred to as the first guide member 12R, and the photographing unit 2 included in the guide member 12 will be referred to as the first photographing unit 2ENT. However, the second guide member 12 and the second photographing unit 2END will also be described in the same manner.

[0020] (How to attach the light-emitting member) Fig. 4 is an enlarged view of part A in Fig. 2. As shown in Fig. 4, the housing 22 is attached with a gap between it and the guide member 12. The light-emitting member 23 is attached to the housing 22 or provided directly below the housing 22. For example, in the present disclosure, it is assumed that the light-emitting member 23 is attached to the housing 22. Light emitted by the light-emitting member 23 attached to the housing 22 is reflected by the guide member 12R and directed toward the user. In other words, the gate 1 has a reflective surface SR that reflects the light emitted by the light-emitting member 23.

[0021] (Housing) The housing 22 includes a base portion 221 and a head portion 222. FIG. 5 is a view of the housing 22 shown in FIG. 4 as viewed from the opposite side of the lane L, i.e., from the outside of the first guide member 12R, in a direction intersecting the extension direction of the gate 1. In other words, it is a cross-sectional view from a side view. As shown in FIG. 5, the head portion 222 houses the camera 21. FIG. 6 is a cross-sectional view of the housing 22 as viewed from the top surface US side. In other words, it is a cross-sectional view from a top view. As shown in FIGS. 5 and 6, when viewed from the top surface US side of the housing 22, the housing 22 has curved surfaces CS at its corners. When viewed from the top surface US side of the housing 22, the base portion 221 has a shape in which the head portion 222 is offset toward the center of the housing 22. When viewed from the top surface US side of the housing 22, the shape of the base portion 221 is smaller than the shape of the head portion 222, so that the housing 22 is attached to the guide member 12 with a partial space between them. A window W is provided in the head portion 222 of the housing 22 at a position facing the lens of the camera 21. The window W protects the lens of the camera 21. The window W is located in a part of a first area A1, which will be described later. The orientation of the optical axis PD of the camera 21 stored in the housing 22 can be changed to match the range of the window W. For example, the optical axis PD may be tilted toward the user U entering the gate 1 relative to the extension direction of the gate 1.

[0022] (Shape of the Light-Emitting Element) As shown again in FIG. 6 , the shape of the light-emitting element 23 is defined as a shape that is on the user side passing through lane L within a cross section of a continuous shape that runs around the periphery of the housing 22 when viewed from the top surface US of the housing 22. The cross section here refers to a surface formed by extending a line from the center of the housing 22 along the extension direction of the gate 1 in a direction perpendicular to the top surface US. The cross-sectional shape of the light-emitting element 23 is not important. As shown in FIG. 7 , there may be multiple users (user U1, user U2) passing through each lane (lane L, lane LL). Gate 1RR further includes a third guide element 12RR adjacent to the first guide element 12R, and the first and third guide elements face each other. A lane LL, through which user U2 can pass, is formed between the first guide element 12R and the third guide element 12RR. The camera 21ENTRR provided in the third guide member 12RR captures a facial image of the user U2 passing through lane LL. In this case, the shape of the light-emitting member 23 is located on the side of the user passing through lane L within the cross section of a continuous shape that goes all the way around the periphery of the housing 22, which has the following advantage: The user U2 passing through the lane LL adjacent to lane L has difficulty seeing the light emitted by the light-emitting member 23 of the photographing unit provided in the first guide member 12R. In other words, the light emitted by the light-emitting member 23 of the photographing unit 2 provided in the first guide member 12R is less likely to enter the field of view of the user U2 passing through the lane LL adjacent to lane L. Therefore, the user U2 can relatively easily see the light emitted by the light-emitting member 23 of the photographing unit 2 provided in the third guide member 12RR. In other words, the user U2 can relatively easily notice the light emitted by the light-emitting member 23 of the photographing unit 2 provided in the third guide member 12RR. In this way, it is difficult for an intruder to look in the wrong direction.

[0023] (Positional Relationship of the Light-Emitting Member) As shown again in FIG. 6 , the position of the light-emitting member 23 overlaps with the housing 22 in the direction D and in a direction perpendicular to the direction D, as viewed from the top surface US of the housing 22. In this case, the position of the reflective surface SR overlaps with the housing 22 in the direction D and in a direction perpendicular to the direction D, as viewed from the top surface US of the housing 22. FIG. 8 is a side view of the housing 22 showing an example of the mounting position of the light-emitting member 23, and FIG. 9 is a cross-sectional view of the housing 22 with the light-emitting member 23 mounted thereon. In the state shown in FIG. 8 , the position of the light-emitting member 23 overlaps with the housing 22 in the vertical direction, as viewed from the side of the housing 22. The side view of the housing 22 refers to the housing 22 as viewed from the direction in which the gate 1 extends. FIG. 9 is also a view from the same direction as FIG. 8 . As shown in FIGS. 8 and 9 , the optical axis of the reflected light from the reflective surface SR is directed toward the center of the housing 22.

[0024] In describing the light-emitting locations of the light-emitting member 23, the "area of ​​the housing 22" will be described in detail with reference to FIG.

[0025] The housing 22 has a first area A1 and a second area A2 aligned with the first area A1 in the direction in which the gate 1 extends, at least in part around the camera. The first area A1 is closer to the lens of the camera 21 than the second area A2. The housing 22 may also have a third area A3 aligned with the first area A1 in a direction intersecting the direction in which the gate 1 extends, at least in part around the camera. The first area A1 is closer to a user U passing through the lane L than the third area A3. The first area A1, second area A2, and third area A3 are areas along the periphery of the housing 22.

[0026] (Light Emitting Pattern of Light-Emitting Member) While waiting for authentication, the light-emitting member 23 can emit light only in the first region A1 out of the first region A1 and the second region A2. Furthermore, the light-emitting member 23 may be configured to emit light only in the first region A1 out of the first region A1 and the third region A3. In the case of the light-emitting member 23 shown in FIG. 6 , the light-emitting member 23 emits light at a light-emitting location corresponding to the first region A1 on the lens side of the camera 21. Note that, of the optical axis of the light-emitting member 23 in the first region A1 and the optical axis of the light-emitting member 23 in the second region A2, only the optical axis of the light-emitting member in the first region A1 may be directed toward the center of the housing 22.

[0027] The light-emitting member 23 can emit light in the first area A1 and the second area A2 when authentication fails. When authentication fails, the door 11 is closed, restricting the user U from exiting the gate 1. In the case of the light-emitting member 23 shown in Figure 6, the light-emitting member 23 emits light at light-emitting locations corresponding to the first area A1 and the second area A2.

[0028] When authentication is successful, the light emitting member 23 sequentially emits light in the first area A1 and the second area A2 from the first area to the second area, thereby urging the user U to exit the gate 1. When authentication is successful, the door 11 opens, allowing the user U to exit the gate 1.

[0029] The light emitting member 23 may also blink during authentication, regardless of whether it is the first area A1 or the second area A2. The blinking makes it difficult for the user U to move their gaze away from the photographing unit 2, thereby informing the user U of the result of the next authentication (whether authentication is successful or unsuccessful) and encouraging the user U to take action afterwards.

[0030] (Information Processing Device) The information processing device 5 authenticates the facial image of the user U and causes the light-emitting members of the photographing unit to emit light according to the authentication status. As shown in FIG. 1 again, the information processing device 5 includes a light emission instruction unit 51, an authentication unit 52, and an authentication data acquisition unit 53. The operation of each unit in the information processing device 5 described below corresponds to at least a part of the information processing method of the present disclosure.

[0031] (Light Emitting Instruction Means) The light emitting instruction means 51 causes the light emitting member of the photographing unit to emit light in accordance with the authentication status of the authentication means 52. The connection method between the photographing unit 2 and the light emitting instruction means 51 may be wired or wireless. The photographing unit that communicates with the information processing device 5 includes a camera that is provided at a gate having a door that opens and closes based on the authentication result of the facial image of the entering user and a guide member on which the door is provided, and that captures facial images, a housing attached to the guide member and that houses the camera, and a light emitting member located at least partially around the camera. In the present disclosure, the photographing unit that includes the light emitting member that is emitted by the information processing device 5 is the photographing unit 2.

[0032] The housing included in the photographing unit that communicates with the information processing device 5 has a first area and a second area aligned with the first area in the direction in which the gate extends, at least in part around the camera, and the first area is closer to the camera lens than the second area. In this case, the light emission instruction means 51 may cause the light emitting member to emit light only in the first area out of the first and second areas while waiting for authentication by the authentication means 52. Furthermore, the light emission instruction means 51 may cause the light emitting member to emit light in both the first and second areas when authentication fails.

[0033] (Authentication Means) The authentication means 52 receives a facial image captured by the photographing unit 2 and authenticates the facial image based on whether it matches the registration information acquired by the authentication data acquisition means 53. The photographing unit 2 and the authentication means 52 may be connected via wire or wireless. Depending on the authentication status of the authentication means 52, the light emission instruction means 51 causes the light-emitting member of the photographing unit to emit light.

[0034] (Authentication Data Acquisition Means) The authentication data acquisition means 53 acquires registration information from the server 7 via the network 6. For example, the registration information is information indicating a facial image of a user permitted to pass through the gate 1, or feature points of the facial image of the user extracted from the facial image. The authentication data acquisition means 53 may also acquire registration information stored in a storage means included in the information processing device 5. In other words, the information processing device 5 may hold the registration information.

[0035] (Information Processing Method) The information processing method of the information processing device 5 in this embodiment will be described. The manufacturing method in this embodiment is carried out according to the flow shown in FIG.

[0036] First, the information processing device 5 determines whether the authentication state of the authentication means 52 is waiting for authentication (step ST101). If it is waiting (step ST101: YES), the light emission instruction means 51 of the information processing device 5 causes the light emitting member 23 to emit light in light emission pattern 1 (step ST105). In light emission pattern 1, the light emission instruction means 51 of the information processing device 5 causes the light emitting member 23 to emit light only in the first area A1 of the first area A1 and the second area A2 of the housing 22 included in the photographing unit 2. If it is not waiting (step ST101: NO), the process proceeds to the next step.

[0037] Next, the information processing device 5 determines whether the authentication state of the authentication means 52 is in progress (step ST102). If it is in progress (step ST102: YES), the light emission instruction means 51 of the information processing device 5 causes the light emitting member 23 to emit light in light emission pattern 2 (step ST106). In light emission pattern 2, the light emission instruction means 51 of the information processing device 5 causes the light emitting member 23 to blink. At this time, it does not matter whether it is the first area A1 or the second area A2. If it is not in standby mode (step ST102: NO), the information processing device 5 proceeds to the next process.

[0038] Next, the information processing device 5 determines whether the authentication status of the authentication means 52 is successful (step ST103). If the authentication status is successful (step ST103: YES), the light-emission instruction means 51 of the information processing device 5 causes the light-emitting members 23 to emit light in light-emission pattern 3 (step ST107). In light-emission pattern 3, the light-emission instruction means 51 of the information processing device 5 causes the light-emitting members 23 to emit light sequentially from the first region A1 to the second region A2 in the first region A1 and the second region A2.

[0039] If the authentication is not successful (step ST103: NO), that is, if the authentication fails, the light-emission instruction means 51 of the information processing device 5 causes the light-emitting members 23 to emit light in light-emission pattern 4 (step ST104). In light-emission pattern 4, the light-emission instruction means 51 of the information processing device 5 causes the light-emitting members 23 to emit light in the first area A1 and the second area A2.

[0040] As a result of the above, the light emission instruction means 51 of the information processing device 5 causes the light emitting member 23 to emit light in accordance with the authentication status. (End)

[0041] (Actions and Effects) According to the photographing unit 2 of the present disclosure, the light-emitting member 23 located in at least a portion of the periphery of the camera 21 stored in the housing 22 can emit light in accordance with the authentication status of the facial image of the user U entering the gate 1. This makes it easier for the user to grasp the position of the camera 21 by relying on the light emitted from the light-emitting member 23. Therefore, the photographing unit according to the present disclosure makes it easy for the user to grasp the camera position when entering the gate.

[0042] (Actions and Effects) According to the information processing device 5 of the present disclosure, the photographing unit that communicates with the information processing device 5 includes a light-emitting member located at least partially around the camera stored in the housing. The light-emitting member is illuminated by the light-emitting instruction means in accordance with the authentication status of the facial image of the user entering the gate. This allows the user to easily determine the position of the camera by relying on the light emitted by the light-emitting instruction means 51. Therefore, the information processing device according to the present disclosure makes it easy for the user to determine the position of the camera when entering the gate.

[0043] Furthermore, the photographing unit of the present disclosure can achieve the following effects by including a camera 21 that is installed in a gate 1 having a door 11 that opens and closes based on the authentication result of a facial image of an entering user U and a guide member 12 on which the door 11 is installed, a housing 22 that stores the camera 21, and a light-emitting member 23 that is located at least partially around the camera 21 and can emit light depending on the authentication status. According to the photographing unit 2 of the present disclosure, the light-emitting member 23 located at least partially around the camera 21 and stored in the housing 22 can emit light depending on the authentication status of the facial image of the user U entering the gate 1. This allows the user to easily determine the location of the camera 21 by relying on the light emitted by the light-emitting member 23. Therefore, the photographing unit of the present disclosure makes it easy for the user to determine the camera's position when entering the gate.

[0044] In addition, in the photographing unit of the present disclosure, the light emitted by the light-emitting element 23 is directed toward the user U, which has the effect that the user U can more easily grasp the position of the camera 21 by relying on the light emitted by the light-emitting element 23.

[0045] In addition, in the photographing unit of the present disclosure, "the light-emitting member 23 is attached to the housing 22 or provided directly below the housing," which also has the effect that "the user U can more easily grasp the position of the camera 21 by relying on the light emitted by the light-emitting member 23."

[0046] Additionally, in the photographing unit of the present disclosure, "the housing 22 is attached to the guide member 12 with a space therebetween, and the light emitted by the light emitting member 23 is directed toward the user through the space," thereby reducing the effect of the light emitted by the light emitting member 23 on the user U. In other words, the effect of reducing the glare felt by the user U can also be obtained.

[0047] Additionally, in the photographing unit of the present disclosure, "the housing 22 has a first area A1 and a second area A2 aligned with the first area A1 in the direction in which the gate 1 extends, at least in a portion of the periphery of the camera 21, the first area A1 being closer to the lens of the camera 21 than the second area A2, and the light-emitting element 23 being capable of emitting light only in the first area A1 of the first area A1 and the second area A2 while waiting for authentication," thereby achieving the effect that "the user U can more easily grasp the position of the camera 21 by relying on the light emitted by the light-emitting element 23."

[0048] In addition, in the photographing unit of the present disclosure, "the direction in which camera 21 faces is inclined toward user U entering gate 1 relative to the extension direction of gate 1, and housing 22 has a third area A3 aligned with first area A1 in at least a part of the periphery of camera 21 in a direction intersecting the extension direction of gate 1, first area A1 is closer to user U than third area A3, and light-emitting member 23 is capable of emitting light only in first area A1 of first area A1 and third area A3," thereby achieving the effect that "because first area A1 is closer to user U than third area A3, user U2 entering the gate next to user U1 entering gate 1 is less likely to misjudge the position of camera 21."

[0049] Additionally, in the photographing unit of the present disclosure, "when authentication fails, the light-emitting member 23 can emit light in the first area A1 and the second area A2," which has the effect of "making it easier to notify people around the gate 1 of the authentication failure." Furthermore, when the gate 1 is passable in the directions D and RD, the second area A2 emits light, making it easier to notify user X who is trying to enter the gate 1 from the opposite direction of the authentication failure.

[0050] In addition, in the photographing unit of the present disclosure, the optical axis of the light-emitting element 23 is directed toward the center of the housing 22, which reduces the effect of the light emitted by the light-emitting element 23 on the camera 21, and also has the effect of making it easier to suppress flare that occurs in facial images.

[0051] Additionally, in the photographing unit of the present disclosure, "the housing 22 has a first area A1 and a second area A2 aligned with the first area A1 in the direction in which the gate 1 extends, at least in a portion of the periphery of the camera 21, the first area A1 is closer to the lens of the camera 21 than the second area A2, and of the optical axis of the light-emitting element 23 in the first area A1 and the optical axis of the light-emitting element 23 in the second area A2, only the optical axis of the light-emitting element 23 in the first area A1 faces toward the center of the housing 22," thereby reducing the impact of light emitted by the light-emitting element 23 on the camera 21 and achieving the effect of "making it easier to suppress flare that occurs in facial images."

[0052] In addition, in the photographing unit of the present disclosure, "the housing 22 or the gate 1 has a reflective surface SR that reflects the light emitted by the light-emitting element 23, and the position of the reflective surface SR overlaps with the housing 22 when viewed from the top surface US side of the housing 22," thereby reducing the impact of the light emitted by the light-emitting element 23 on the camera 21 and also achieving the effect of "making it easier to suppress flare that occurs in facial images."

[0053] In addition, in the photographing unit of the present disclosure, "the optical axis of the reflected light on the reflecting surface SR is directed toward the center of the housing 22," thereby reducing the effect of the light emitted by the light-emitting element 23 on the camera 21, and also achieving the effect of "making it easier to suppress flare that occurs in facial images."

[0054] Additionally, in the photographing unit of the present disclosure, "the position of the light-emitting member 23 overlaps with the housing 22 when viewed from the top surface US side of the housing 22," which also provides the effect that "the photographing unit can be more easily made smaller than when the light-emitting member 23 is located on the outer periphery of the housing 22 when viewed from the top surface US side of the housing 22." Furthermore, "the position of the light-emitting member 23 overlaps with the housing 22 when viewed from the top surface US side of the housing 22," which also provides the effect that "flare that occurs in facial images can be more easily suppressed."

[0055] In addition, in the photographing unit of the present disclosure, "the position of the light-emitting member 23 overlaps with the housing 22 or the gate 1 when viewed from the side of the housing 22," which also has the effect of "making it easier to make the photographing unit smaller than when the light-emitting member 23 is located on the outer peripheral surface of the housing 22 when viewed from the side of the housing 22."

[0056] In addition, in the photographing unit of the present disclosure, "when viewed from the top surface US side of the housing 22, the housing 22 has curved surfaces CS at the corners," which also has the effect of "making it easier to deflect the force of a collision when the user U or luggage carried by the user U collides with the housing 22."

[0057] <Modifications> Furthermore, the shape of the light-emitting member 23 may be a shape having light-emitting portions in the first region A1, the second region A2, and the third region A3 disclosed above, as shown in FIG. 12 . For example, as shown in FIGS. 12 and 13 , the direction of the camera 21 is assumed to be along the extension direction of the gate 1. In this case, the capturing range is wider than when the direction of the camera 21 disclosed above is tilted toward the user entering the gate 1. Therefore, to correspond to the capturing range, the first region A1 may be a wider first region A1INST in FIG. 13 . Furthermore, as shown in FIG. 14 , the second region A2 may be a wider second region A2INST. By making the second region A2 wider, it becomes easier to notify more people around the gate 1 of the authentication failure in the event of an authentication failure.

[0058] <Modifications> The light emitting member 23 may be configured so that a portion thereof overlaps with the housing 22 in the direction D and in a direction perpendicular to the direction D, when viewed from the top surface US side of the housing 22. Even in this case, the size of the light emitting member 23 can be reduced compared to a configuration in which the entire light emitting member 23 does not overlap with the housing 22 in the direction D and in a direction perpendicular to the direction D, when viewed from the top surface US side of the housing 22.

[0059] The light emitting member 23 may be configured to overlap a portion of the housing 22 in the vertical direction when viewed from the side of the housing 22. Even in this case, the size can be reduced compared to a configuration in which the entire light emitting member 23 does not overlap the housing 22 in the vertical direction when viewed from the side of the housing 22.

[0060] Furthermore, the optical axis of the light-emitting member 23 does not have to point toward the center of the housing 22. For example, the optical axis of the light-emitting member 23 may point vertically or toward the outside of the housing 22. Even in this case, the user can easily grasp the position of the camera 21 through direct light or light reflected from the reflective surface SR. Even if the optical axis of the light-emitting member 23 does not point toward the center of the housing 22, the user's glare can be reduced compared to direct light when notifying the user through light reflected from the reflective surface SR. Furthermore, even if the optical axis of the light-emitting member 23 does not point toward the center of the housing 22, the position of the reflective surface SR overlaps with the housing 22 when viewed from the top surface US of the housing 22, thereby reducing the impact of light emitted by the light-emitting member 23 on the camera 21 and achieving the effect of "facilitating suppression of flare in facial images."

[0061] The light-emitting member 23 is not limited to a configuration that emits directional light. In other words, the light-emitting member 23 may emit diffused light. Even in this case, the user can easily grasp the position of the camera 21 by direct light or light reflected from the reflective surface SR. Furthermore, even if the light-emitting member 23 emits diffused light, when notifying the user by light reflected from the reflective surface SR, the user's glare can be reduced compared to direct light. Furthermore, even if the light-emitting member 23 does not emit directional light, the light-emitting member 23 overlaps the housing 22 when viewed from the top surface US of the housing 22, thereby reducing the impact of the light emitted by the light-emitting member 23 on the camera 21 and achieving the effect of "facilitating suppression of flare occurring in facial images."

[0062] The shape of the light-emitting member 23 may also be as shown in FIG. 15 . For example, the shape of the light-emitting member 23 may be a continuous shape that extends around the periphery of the housing 22 when viewed from the top surface US side of the housing 22. In this case, the light-emitting location of the light-emitting member 23 may be changeable. By changing the light-emitting location of the light-emitting member 23, the arrangement of the photographing units 2 shown in FIG. 16 can be changed to the arrangement shown in FIG. 17 . When changing the arrangement of the photographing units 2, the direction of the optical axis PD of the camera 21 stored in the housing 22 may be changed as appropriate. Note that the window W provided in the head portion 222 of the housing 22 may be located across part of the first area A1 and the second area A2.

[0063] The gate 1 may also have one guide member 12, and an openable / closable door 11 may be provided on the one guide member 12. In this case, the gate 1 may be composed of one guide member and a side wall portion of a predetermined height.

[0064] Alternatively, the gate 1 may have one guide member 12, and one guide member 12 may be provided with a plurality of photographing units 2.

[0065] Furthermore, two photographing units 2 (a first photographing unit 2ENT and a second photographing unit 2END) may be provided on one guide member.

[0066] For example, in the passage management system 10, the housing 22 and the gate 1 may be colored in a first color, and the light-emitting member 23 may emit light in a second color different from the first color. This makes it easier for the user U to grasp the position of the photographing unit 2 including the light-emitting member 23 when entering the gate 1.

[0067] For example, in the passage management system 10, the color of the door 11 may change to a color similar to the color of the light-emitting member 23. This makes it easier for the user U to understand the authentication status.

[0068] For example, the traffic control system 10 may be applied to a fare payment gate for public transportation such as a train.

[0069] Furthermore, in the passage management system 10, the gate 1 includes a first guide member 12R and a second guide member 12L as guide members 12. The first guide member 12R includes a photographing unit 2 as a first photographing unit 2ENT, and the second guide member 12L includes a photographing unit 2 as a second photographing unit 2END. The light-emitting member 23 of the second photographing unit 2END may be configured to emit light in conjunction with the light-emitting member 23 of the first photographing unit when authentication fails. That is, as shown in FIG. 18 , when authentication fails, in addition to the light-emitting member 23 of the first photographing unit 2ENT, which photographs from the entrance E1 toward the direction D, the light-emitting member 23 of the second photographing unit, which photographs from the entrance E2 toward the direction R, may also emit light in conjunction with the light-emitting member 23 of the first photographing unit. This allows the user U to see the light-emitting member 23 of the photographing unit 2 located near the entrance they entered, making it easier to understand the status of authentication.

[0070] For example, as shown in FIG. 19 , the position of the light emitting member 23 may be on the outer peripheral surface of the housing 22 when viewed from the side of the housing 22. In this case, the light emitted by the light emitting member 23 may be directed directly toward the user. In addition, in this case, the light emitting member 23 is not limited to a configuration that emits directional light, and the direction of the optical axis is not limited. In other words, it may be configured to emit diffused light. Furthermore, the optical axis of the light emitting member 23 does not have to point toward the center of the housing 22. FIG. 19 illustrates, as an example, a configuration in which the optical axis points toward the center of the housing 22.

[0071] For example, as shown in FIG. 20 , the light emitting member 23 may be located on the outer peripheral surface of the housing 22 when viewed from the side of the housing 22, and the photographing unit 2 may have a cover 24 that suppresses diffusion of the light emitted by the light emitting member 23. This suppresses the scattering of the light emitted by the light emitting member 23. In this case, the light emitting member 23 is not limited to a configuration that emits directional light, and the direction of the optical axis is not limited. In other words, it may be configured to emit diffused light. Furthermore, the optical axis of the light emitting member 23 does not have to point toward the center of the housing 22. FIG. 20 illustrates, as an example, a configuration in which the optical axis points toward the center of the housing 22.

[0072] For example, as shown in FIG. 21 , the position of the light-emitting member 23 does not have to overlap with the housing 22 when viewed from the side of the housing 22. In other words, it may be located in the space between the housing 22 and the guide member 12 of the gate 1. In this case, the light-emitting member 23 is not limited to a configuration that emits directional light, and the direction of the optical axis is not limited. In other words, it may be configured to emit diffused light. Furthermore, the optical axis of the light-emitting member 23 does not have to face toward the center of the housing 22. FIG. 21 shows, as an example, a configuration in which the optical axis faces toward the center of the housing 22.

[0073] For example, as shown in FIG. 22 , the light-emitting member 23 may be provided directly below the housing 22 when viewed from the side of the housing. For example, the light-emitting member 23 may be provided on the guide member 12 of the gate 1. In this case, the housing 22 has a reflective surface SR that reflects the light emitted by the light-emitting member 23. In addition, in this case, the light-emitting member 23 is not limited to a configuration that emits directional light, and the direction of the optical axis is not limited. In other words, it may be configured to emit diffused light. Furthermore, the optical axis of the light-emitting member 23 does not have to face toward the center of the housing 22. FIG. 22 shows, as an example, a configuration in which the optical axis faces toward the center of the housing 22.

[0074] For example, as shown in FIG. 23 , the position of the light-emitting member 23 may overlap with the gate 1 when viewed from the side of the housing 22. In this case, the housing 22 has a reflective surface SR that reflects the light emitted by the light-emitting member 23. In addition, in this case, the light-emitting member 23 is not limited to a configuration that emits directional light, and the direction of the optical axis is not limited. In other words, it may be configured to emit diffused light. Furthermore, the optical axis of the light-emitting member 23 does not have to face toward the center of the housing 22. FIG. 23 shows, as an example, a configuration in which the optical axis faces toward the center of the housing 22.

[0075] Furthermore, the first region A1 may be present only in a linear portion of the region along the circumferential surface of the housing 22. In this case, the light emitting member 23 may have a linear shape when viewed from the top surface US side of the housing 22.

[0076] Second Embodiment An embodiment according to the present disclosure will now be described with reference to the drawings. An example of the configuration of a photographing unit according to the present disclosure will now be described with reference to FIG.

[0077] (Configuration) The photographing unit 2m is provided at a gate having a door that opens and closes based on the results of authentication of the facial image of the entering user and a guide member on which the door is provided, and includes a camera 21m that photographs facial images, a housing 22m attached to the guide member and storing the camera 21m, and a light-emitting member 23m that is located at least in part around the camera 21m and can emit light depending on the authentication status.

[0078] (Actions and Effects) According to the photographing unit 2m of the present disclosure, the light-emitting member 23m located at least partially around the camera 21m housed in the housing 22m can emit light according to the authentication status of the facial image of the user entering the gate. This makes it easier for the user to grasp the position of the camera 21m by relying on the light emitted from the light-emitting member 23m. Therefore, the photographing unit according to the present disclosure makes it easy for the user to grasp the camera position when entering the gate.

[0079] Third Embodiment An embodiment according to the present disclosure will now be described with reference to the drawings. An example of the configuration of an information processing device according to the present disclosure will be described with reference to FIG.

[0080] (Configuration) The information processing device 5m is provided at a gate having a door that opens and closes based on the results of authentication of the facial image of an entering user and a guide member on which the door is provided, and is equipped with a light emission instruction means 51m that causes the light emitting element of the photographing unit, which includes a camera that photographs facial images, a housing attached to the guide member and storing the camera, and a light emitting element located at least partially around the camera, to emit light in accordance with the authentication status, and an authentication means 52m that performs authentication.

[0081] (Actions and Effects) According to the information processing device 5m disclosed herein, the photographing unit that communicates with the information processing device 5m includes a light-emitting member located at least partially around the camera housed in the housing. The light-emitting member is illuminated by the light-emitting instruction means 51m depending on the authentication status of the facial image of the user entering the gate. This allows the user to easily determine the position of the camera by relying on the light emitted by the light-emitting instruction means 51m. Therefore, the information processing device according to the present disclosure makes it easy for the user to determine the position of the camera when entering the gate.

[0082] Fourth Embodiment An embodiment according to the present disclosure will be described below with reference to the drawings. An example of an information processing method according to the present disclosure will be described below with reference to Fig. 26. The information processing method according to the present disclosure is performed according to the flow shown in Fig. 26.

[0084] (Actions and Effects) According to the information processing method of the present disclosure, a light-emitting element located at least partially around the camera can emit light depending on the authentication status of the facial image of the user entering the gate. The light-emitting element is then illuminated while waiting for authentication, and authentication is then performed based on the facial image. This allows the user to easily determine the camera's position by relying on the light emitted by the light-emitting element. Therefore, the photographing unit according to the present disclosure makes it easy for the user to determine the camera's position when entering the gate.
