[0010] Hereinafter, embodiments of an information processing device, an information processing system, an information processing method, and a program will be described with reference to the drawings. [1: First embodiment]

[0011] An information processing device, an information processing system, an information processing method, and a program according to a first embodiment will be described below. An information processing device, an information processing system, an information processing method, and a program according to a first embodiment will be described below using an information processing device 1 according to this disclosure.

[0012] An information processing device 1 according to this disclosure will be described with reference to Figures 1 and 2. As shown in Figure 1, the information processing device 1 includes a tracking unit 11 and a control unit 12. The operation of the information processing device 1 will be described with reference to the flowchart in Figure 2.

[0013] As shown in FIG. 2, the tracking unit 11 tracks a target (step S11). The "target" is a target to be authenticated. The tracking unit 11 may track a first target and a second target. The first target and the second target are included in a first group. In this embodiment, for example, targets that act together may be considered to be targets included in the same group. Information indicating that the first target and the second target are included in the first group may be registered in advance. The tracking unit 11 may acquire information indicating that the first target and the second target are included in the first group before the operation of step S11. The tracking unit 11 tracks the first target while recognizing that the first target is included in the first group. Furthermore, the tracking unit 11 tracks the second target while recognizing that the second target is included in the first group.

[0014] The control unit 12 controls the entry of the target into the predetermined area (step S12). The predetermined area may be an area where the entry of a target who has failed authentication is restricted. Hereinafter, an area where the entry of a target who has failed authentication is restricted is referred to as a "restricted area." The restricted area may be an area where the entry of one or more targets is restricted when two targets, a first target and a second target, are present. If the authentication of the first target fails, the control unit 12 may control to restrict the entry of the first target into the restricted area. As described above, the first target and the second target are included in the first group. In this case, the control unit 12 controls to restrict the entry of the first target who has failed authentication and the second target who is included in the same group as the first target into the predetermined area.

[0015] In this way, the information processing device 1 performs an information processing method in which the first and second objects included in the first group are tracked, and if authentication of the first object fails, the first and second objects are controlled to be restricted from entering a specified area.

[0016] The information processing device 1 may be realized by a computer reading a computer program recorded on a recording medium. In this case, the computer program may cause the computer to execute an information processing method that tracks a first object and a second object included in a first group, and, if authentication of the first object fails, controls to restrict entry of the first object and the second object into a predetermined area. [Technical effect of information processing device 1]

[0017] The information processing device 1 disclosed herein controls to restrict the movement of not only the subject who has failed authentication but also the other subjects in the group, thereby preventing subjects in the group from losing sight of each other and being unable to act together. [2: Second embodiment]

[0018] A second embodiment of an information processing device, an information processing system, an information processing method, and a program will be described with reference to Fig. 3 to Fig. 7. Hereinafter, the second embodiment of an information processing device, an information processing system, an information processing method, and a program will be described using an information processing system S. Note that, for the second embodiment, descriptions that overlap with the description of the first embodiment will be omitted as appropriate. [2-1: Configuration of Information Processing System S]

[0019] Fig. 3 is a schematic diagram showing an overview of an information processing system S according to this disclosure. Fig. 4 is a block diagram showing the configuration of an information processing device 2 according to this disclosure.

[0020] As shown in FIG. 3, the information processing system S is applied to a location where a first object TP1 and a second object TP2 can move side by side. The location where the first object TP1 and the second object TP2 can move side by side is referred to as a lane L. The destination of the first object TP1 and the second object TP2 may be at the end of the direction of the arrow illustrated in FIG. 3. The first object TP1 and the second object TP2 may be guided to move in the direction of the arrow illustrated in FIG. 3. The first object TP1 and the second object TP2 move generally in the longitudinal direction of the lane L. The direction in which the first object TP1 and the second object TP2 move may be referred to as the "movement direction." In the lane L, the first object TP1 and the second object TP2 can move side by side in a direction other than the movement direction. In the lane L, the first object TP1 and the second object TP2 may be able to move side by side in the short direction of the lane L (referred to as the "width direction of the lane L"). The width direction of the lane L may have a length approximately twice the width of the passageway through which an average adult can move. In other words, the lane L has a width that allows two subjects lined up in directions different from the direction of movement to move.

[0021] As shown in FIG. 3, the information processing system S may include a camera 27, a first camera 281, a second camera 282, and an information processing device 2. The camera 27 may be a camera capable of capturing light in the visible wavelength range (a so-called visible light camera). Alternatively, the camera 27 may be a camera capable of capturing light in the near-infrared wavelength range (a so-called near-infrared camera). Furthermore, the image captured by the camera 27 may be a concept that includes a moving image. The first camera 281 and the second camera 282 may be a camera capable of capturing light in the near-infrared wavelength range (a so-called near-infrared camera). Alternatively, the first camera 281 and the second camera 282 may be a camera capable of capturing light in the visible wavelength range (a so-called visible light camera). Furthermore, the image captured by the first camera 281 and the second camera 282 may be a concept that includes a moving image.

[0022] The camera 27 captures an image of the space in which the first object TP1 and the second object TP2 can move side by side. The camera 27 captures an image including the first object and the second object. The camera 27 may capture an image of the space in which the first object TP1 and the second object TP2 can move side by side in the width direction of the lane L. As shown in FIG. 3, the camera 27 may be provided in a location that provides an overhead view of the first object TP1 and the second object TP2 moving side by side. The camera 27 may be provided to capture an image of the area in which the first object TP1 and the second object TP2 can move side by side. The camera 27 may be provided to capture an image of an area that can be captured by at least one of the first camera 281 and the second camera 282.

[0023] The first camera 281 may be provided at one end in a direction different from the direction of movement. For example, the first camera 281 may be provided at one end in a horizontal direction perpendicular to the direction of movement. In other words, the first camera 281 may be provided at one end in the width direction of the lane L. The second camera 282 may be provided at the other end in the direction different from the direction of movement. For example, the second camera 282 may be provided at the other end in the horizontal direction perpendicular to the direction of movement. In other words, the second camera 282 may be provided at the other end in the width direction of the lane L. In other words, it may be said that there is a space between the first camera 281 and the second camera 282 in which the first object TP1 and the second object TP2 can move side by side.

[0024] The first camera 281 may capture an image of the iris of a target moving on one side of the width direction of the lane L from one end side of the lane L. In the case illustrated in FIG. 3, the first camera 281 may be provided on the right side of the lane L as seen from the target (the left side of the lane L as seen from the camera 27). Also, in the case illustrated in FIG. 3, the first camera 281 may capture an image of the iris of the first target TP1 moving on the right side of the lane L from the right side of the lane L as seen from the target.

[0025] The second camera 282 may capture an image of the iris of a target moving on the other side of the width direction of the lane L from the other end side of the lane L. In the case illustrated in FIG. 3, the second camera 282 may be provided on the left side of the lane L as seen from the target (the right side of the lane L as seen from the camera 27). Also, in the case illustrated in FIG. 3, the second camera 282 may capture an image of the iris of the second target TP2 moving on the left side of the lane L from the left side of the lane L as seen from the target.

[0026] 3 illustrates an example in which camera 27 is provided in a location where it can overlook first object TP1 and second object TP2, but the location in which camera 27 is provided is not limited to this. Camera 27 may be provided near at least one of first camera 281 and second camera 282. For example, camera 27 may be provided in the same housing as first camera 281. Camera 27 may also be provided in the same housing as second camera 282. A plurality of cameras 27 may be provided. That is, camera 27 may be provided near first camera 281 and near second camera 282.

[0027] Camera 27 may capture images used to track the subject, and may capture images to determine which camera captures the subject's iris, and may capture images to identify the location of the subject's iris.

[0028] 4, the information processing device 2 includes an arithmetic unit 21, a storage device 22, a communication device 23, an input device 24, and an output device 25. The arithmetic unit 21, the storage device 22, the communication device 23, the input device 24, and the output device 25 may be connected via a data bus 26. The arithmetic unit 21 may include, for example, at least one of a central processing unit (CPU), a graphics processing unit (GPU), a field programmable gate array (FPGA), a tensor processing unit (TPU), and a quantum processor.

[0029] The storage device 22 may include, for example, at least one of a RAM (Random Access Memory), a ROM (Read Only Memory), a hard disk device, a magneto-optical disk device, an SSD (Solid State Drive), and an optical disk array. In other words, the storage device 22 may include a non-transitory recording medium. The storage device 22 is capable of storing desired data. For example, the storage device 22 may temporarily store a computer program executed by the calculation device 21. The storage device 22 may temporarily store data that is temporarily used by the calculation device 21 when the calculation device 21 is executing a computer program.

[0030] The communication device 23 may be capable of communicating with devices external to the information processing device 2. The communication device 23 may perform wired communication or wireless communication. The information processing device 2 is capable of communicating with the camera 27, the first camera 281, and the second camera 282 included in the information processing system S. The information processing device 2 may communicate with the camera 27, the first camera 281, and the second camera 282 via the communication device 23. The information processing device 2 and the camera 27, the first camera 281, and the second camera 282 may perform wireless communication or wired communication.

[0031] The input device 24 is a device capable of accepting information input to the information processing device 2 from the outside. The input device 24 may include an operation device (e.g., a keyboard, a mouse, a touch panel, etc.) that can be operated by a user of the information processing device 2. The input device 24 may include a recording medium reading device that can read information recorded on a recording medium that is detachable from the information processing device 2, such as a USB (Universal Serial Bus) memory. Note that when information is input to the information processing device 2 via the communication device 23 (in other words, when the information processing device 2 obtains information via the communication device 23), the communication device 23 may function as an input device.

[0032] The output device 25 is a device capable of outputting information to the outside of the information processing device 2. The output device 25 may output visual information such as characters or images, auditory information such as sound, or tactile information such as vibration, as the information. The output device 25 may include, for example, at least one of a display, a speaker, a printer, and a vibration motor. The output device 25 may be capable of outputting information to a recording medium detachable from the information processing device 2, such as a USB memory. Note that when the information processing device 2 outputs information via the communication device 23, the communication device 23 may function as the output device.

[0033] The arithmetic device 21 in this embodiment has, as logically realized functional blocks or as physically realized processing circuits, a tracking unit 211, a control unit 212, an image acquisition unit 213, an authentication unit 214, and a determination unit 216. The "tracking unit 211" and the "control unit 212" are components corresponding to the "tracking unit 11" and the "control unit 12" in the first embodiment described above, respectively.

[0034] At least one of the tracking unit 211, the control unit 212, and the image acquisition unit 213 may be realized in a format in which a logical functional block and a physical processing circuit (i.e., hardware) are mixed. When at least one of the tracking unit 211, the control unit 212, and the image acquisition unit 213 is a functional block, at least one of the tracking unit 211, the control unit 212, and the image acquisition unit 213 may be realized by the calculation device 21 executing a predetermined computer program.

[0035] The arithmetic device 21 may acquire (in other words, read) the predetermined computer program from the storage device 22. The arithmetic device 21 may read the predetermined computer program stored in a computer-readable, non-transitory recording medium using a recording medium reading device (not shown) included in the information processing device 2. The arithmetic device 21 may acquire (in other words, download or read) the predetermined computer program from a device (not shown) external to the information processing device 2 via the communication device 23. Note that the recording medium for recording the predetermined computer program executed by the arithmetic device 21 may be at least one of an optical disk, a magnetic medium, a magneto-optical disk, a semiconductor memory, and any other medium capable of storing a program.

[0036] The information processing system S may be applied to determining whether or not a subject can enter a restricted area and to managing entry to the restricted area. The restricted area may be an area into which a subject who has been successfully authenticated can enter. The restricted area may be an area before the end point E of the lane L in the direction of movement, as illustrated in FIG. 3. Therefore, the information processing system S may be configured to authenticate a subject in the lane L after the end point E of the lane L in the direction of movement. The subject may be a subject of biometric authentication (i.e., authentication using biometric information). The information processing system S may be configured to authenticate the subject by biometric authentication using biometric information.

[0037] Biometric information is information about the physical characteristics of a subject. Examples of biometric information include at least one of a facial image including the subject's face, an iris image including the subject's iris, a fingerprint pattern of the subject, a palm print pattern of the subject, a vein pattern of the subject's fingers and palm, audio information including the subject's voice, and sound information including the subject's otoacoustic emissions. Examples of authentication using biometric information include at least one of face authentication, iris authentication, fingerprint authentication, palm print authentication, vein authentication, voiceprint authentication, and earacoustic authentication. A subject may be authenticated using one piece of biometric information. Alternatively, a subject may be authenticated using a combination of multiple pieces of biometric information. In other words, a subject may be a subject of multimodal biometric authentication. [2-2: Information processing method executed by information processing device 2]

[0038] The information processing device 2 is configured as a device for sequentially authenticating objects moving in a movement direction and sequentially controlling the objects' entry into a restricted area. An information processing method executed by the information processing device 2 will be described with reference to Figs. 5 to 7. Fig. 5 is a flowchart showing the flow of the information processing method executed by the information processing device 2. Figs. 6 and 7 are schematic diagrams showing an overview of the information processing method executed by the information processing device 2.

[0039] As shown in FIG. 5, the image acquisition unit 213 acquires an image from the camera 27 (step S21). The camera 27 may be provided so as to be able to capture an image of the lane L (this area is referred to as the "tracking area") from the positions where the first camera 281 and the second camera 282 are provided to a predetermined position behind the lane L in the direction of movement. In this case, the image acquisition unit 213 may be said to acquire an image of the tracking area. The camera 27 may be provided at a height of, for example, 2.5 meters. If the camera 27 is provided at a position higher than the average human height, the image captured by the camera 27 is likely to include the head area and upper body area of ​​the target. The head area and upper body area may be areas suitable for tracking the target. Furthermore, if multiple cameras 27 are provided, the image acquisition unit 213 may acquire images from the multiple cameras 27.

[0040] FIG. 6(a) illustrates an example of an image I acquired from the camera 27. FIG. 6(a) illustrates an example where there are four targets in the tracking area. The tracking unit 211 tracks each of the targets included in the image. The tracking unit 211 tracks each of the targets in the tracking area based on the image. In the example shown in FIG. 6(a), the tracking unit 211 may track each of the first target TP1, the second target TP2, the third target TP3, and the fourth target TP4. Each of "TP1," "TP2," "TP3," and "TP4" may be, for example, an example of identification information (referred to as a "tracking ID") of the tracking target.

[0041] The image used by the tracking unit 211 for tracking may be one frame of a video. In this case, the image acquisition unit 213 may sequentially acquire multiple frames constituting the video as images. The tracking unit 211 may perform tracking by associating the same object between a past frame and a current frame. For example, the tracking unit 211 may perform tracking by determining the position of the head region in the image. The tracking unit 211 may associate the same object in different frames based on the position of the head region in the image. The tracking unit 211 may perform tracking by determining the identity of the image pattern of the head region, for example. Furthermore, the tracking unit 211 may perform tracking by determining the similarity of feature information extracted from the image of the head region.

[0042] When a plurality of cameras 27 are provided, the tracking unit 211 may track each of the targets included in each of the plurality of images captured by the plurality of cameras 27. For example, the tracking unit 211 may integrate the targets included in each of the plurality of images by extracting and matching characteristic parts of the targets. The characteristic parts of the targets may be, for example, the head region of the target, the upper body region of the target, or items worn by the target. The characteristic parts of the targets may be parts that can distinguish between individuals. The characteristic parts of the targets do not have to be parts that can identify an individual.

[0043] The tracking unit 211 acquires association information indicating an association between a group and an object included in the group (step S22). The tracking unit 211 may acquire, as the association information, group information indicating that the object is included in a first group. The tracking unit 211 may also acquire, as the association information, group information indicating that the object is included in a group (e.g., a second group) different from the first group.

[0044] For example, a target included in a group may carry a device capable of outputting a signal corresponding to the group information at least when moving within lane L. The tracking unit 211 may detect the position of a target included in the first group and the position of a target included in a group different from the first group (for example, a second group) based on the output position of the signal corresponding to the group information.

[0045] The tracking unit 211 associates the tracking target with a group including the tracking target (step S23). The tracking unit 211 may associate the tracking ID with information for distinguishing the group. For example, it is assumed that the first group includes a first target and a second target, and the second group includes a third target and a fourth target. In this case, the tracking unit 211 may associate the tracking target with the group including the tracking target by adding information that can distinguish that the first target TP1 and the second target TP2 are included in the same group, and adding information that can distinguish that the third target TP3 and the fourth target TP4 are included in the same group, as shown in FIG. 6(b), for example.

[0046] The determining unit 216 may identify two objects from the objects included in the image. The determining unit 216 may identify two objects located in the foreground in the image from among the objects for which it has not been determined whether they will be captured by the first camera 281 or the second camera 282.

[0047] 6, it is assumed that it has not been determined whether the first camera 281 or the second camera 282 will capture the image of any of the first object TP1, the second object TP2, the third object TP3, and the fourth object TP4. In this case, the determination unit 216 may identify the two objects (the first object TP1 and the second object TP2) located in the foreground in the image I. Note that, if it has not been determined whether the first camera 281 or the second camera 282 will capture the image of less than two objects, the determination unit 216 may identify the less than two objects.

[0048] Based on the image, the determination unit 216 may determine one of the two targets as the target to be imaged by the first camera 281, and the other of the two targets as the target to be imaged by the second camera 282. The determination unit 216 may determine the target to be imaged by the first camera 281 and the target to be imaged by the second camera 282 based on at least one of the positional relationship between the first target and the second target included in the image and the distance of each of the first target and the second target to the camera 27. In the example shown in FIG. 6, the determination unit 216 may determine that, of the first target TP1 and the second target TP2, the first target TP1 located on the left side of the image I is the first target whose iris is to be imaged by the first camera 281, and may determine that the second target TP2 located on the right side of the image I is the second target whose iris is to be imaged by the second camera 282. Alternatively, the determination unit 216 may divide the image along a vertical line, and determine that one pair of objects included in one of the divided images is to be captured by the first camera 281, and that the other object included in the other divided image is to be captured by the second camera 282. The determination unit 216 may divide the image in the vertical direction along the vertical line so that one object is included in one image, and the other object is included in the other image.

[0049] In addition, if the image contains one subject, the determination unit 216 may divide the image into left and right halves in the middle, and determine that the first camera 281 will capture the subject if the subject is included in the left image, and that the second camera 282 will capture the subject if the subject is included in the right image.

[0050] The determination unit 216 may irradiate the first object TP1 with directional light from a position adjacent to the first camera 281, and may irradiate the second object TP2 with directional light from a position adjacent to the second camera 282. The determination unit 216 may irradiate the first object TP1 with light from a position adjacent to the first camera 281, and may irradiate the second object TP2 with light from a position adjacent to the second camera 282, for example, by using a laser pointer. Furthermore, the determination unit 216 may display information indicating the first object TP1 at a position adjacent to the first camera 281, and may display information indicating the second object TP2 at a position adjacent to the second camera 282.

[0051] Furthermore, when the tracking unit 211 detects at least one of an object in the image at the same position for a predetermined time or longer and at the same size for a predetermined time or longer, it may determine that the object is standing still. The information processing device 2 may have a mechanism for outputting information to the object to warn that it is standing still, and may output the information to warn that it is standing still. Furthermore, the camera 27 may be installed at a height that prevents the object from looking into the camera lens, thereby preventing the object from standing still.

[0052] The first camera 281 may capture an image of the iris of the first target TP1 and acquire an iris image 1 including the iris of the first target TP1. The second camera 282 may capture an image of the iris of the second target TP2 and acquire an iris image 2 including the iris of the second target TP2. The authentication unit 214 acquires the iris image 1 from the first camera 281 and the iris image 2 from the second camera 282 as biometric information. The authentication unit 214 performs authentication using the iris image 1 and authentication using the iris image 2.

[0053] The authentication unit 214 authenticates the target by comparing an iris image, which is biometric information of the target, with registered registration information. The authentication unit 214 may calculate a matching score by comparing the iris image with a pre-registered iris image. The matching score may mean a value indicating the degree of match between the acquired iris image and the pre-registered iris image. The matching score may mean a value indicating the degree of match between a feature extracted from the iris image and a pre-registered feature. Therefore, the authentication unit 214 may calculate the matching score by comparing the feature extracted from the iris image with a pre-registered feature.

[0054] The authentication unit 214 determines whether the iris authentication has been successful. In iris authentication, if the matching score is equal to or greater than a predetermined threshold, the target is determined to be a person who has been registered in advance. The authentication unit 214 may determine that the iris authentication has been successful if the matching score exceeds the predetermined threshold. In this case, the authentication unit 214 may determine that the iris authentication has failed if the matching score is smaller than the predetermined threshold. Note that if the matching score is equal to the predetermined threshold, the authentication unit 214 may determine that the biometric authentication has been successful or failed.

[0055] In addition to iris authentication, authentication unit 214 may also perform authentication using a facial image (face authentication). Authentication unit 214 may perform face authentication by comparing a facial image of a target included in an image captured by camera 27 with a facial image of a target registered in advance. In other words, authentication unit 214 may perform multimodal authentication.

[0056] In this embodiment, the first object may be the object in the group that arrives at the end point E first. The object that arrives at the end point E may be an object for which authentication has been completed. The object for which authentication has been completed may be an object for which it has been determined whether authentication has been successful or unsuccessful. Alternatively, the object that arrives at the end point E may be said to have been authenticated. For example, an object that has been successfully authenticated before arriving at the end point E may be an object for which authentication has been successfully completed. Furthermore, an object that has not been successfully authenticated before arriving at the end point E may be an object for which authentication has failed. Note that in FIG. 6, the second object TP2 is illustrated as an object moving on the right side of the drawing, but if an object moving on the right side of the drawing arrives at the end point E before an object moving on the left side of the drawing, the object moving on the right side of the drawing may be referred to as the first object. The determination of step S24 is repeated until the first object arrives at the end point E.

[0057] If the first target has arrived at the end point E (step S24: other than "No") and the authentication of the first target has been successful (step S24: authentication successful), the control unit 212 does not restrict the first target from entering the restricted area (step S25). On the other hand, if the authentication of the first target has been completed (step S24: other than "No") and the authentication of the first target has failed (step S24: authentication failed), the control unit 212 restricts the first target from entering the restricted area.

[0058] The control unit 212 determines whether an object different from the first object is included in the first group (i.e., the group including the first object) (step S26). The control unit 212 may also determine whether an object moving alongside the first object is included in the first group (i.e., the group including the first object). Being alongside the first object means being alongside in a direction different from the direction of movement of the first object, and may mean being alongside in the width direction of the lane L. For example, the control unit 212 may determine whether an object moving alongside the first object that has reached the end point E of the lane L is included in the first group.

[0059] 6, the second object TP2 moving alongside the first object TP1 is included in the first group (step S26: Yes), and the control unit 212 restricts the first and second objects from entering the restricted area (step S27).

[0060] FIG. 7(a) illustrates an example in which a first object TP1 and a third object TP3, which is a different object from the first object TP1, are moving. In other words, FIG. 7(a) illustrates an example in which the first object TP1 and the third object TP3 are moving side by side. The third object TP3 is included in the second group but not in the first group (step S26: No). In this case, the control unit 212 does not restrict the third object from entering the restricted area, but restricts only the first object from entering the restricted area (step S28). Note that, as illustrated in FIG. 7(b), if a second object TP2, which is included in the first group, moves behind the first object TP1, the control unit 212 may restrict the second object from entering the restricted area when the second object TP2 reaches the end point E of the lane L.

[0061] A display device may be provided at the end point E of the lane L. In this case, the control unit 212 may notify the target of the success or failure of the target's authentication by displaying information indicating the success or failure of the target's authentication on the display device, and may control the target's entry into the restricted area.

[0062] The control unit 212 may display on the display device an action to be taken by the subject depending on whether the authentication was successful or not. For example, the action to be taken by a subject who is successfully authenticated may be to enter the restricted area. For example, the action to be taken by a subject who is unsuccessful in authentication may be to repeat the movement within lane L. For example, the action to be taken by a subject who is unsuccessful in authentication may be to undergo an examination by an examiner who examines whether or not the subject is allowed to enter the restricted area.

[0063] For example, a gate may be provided at the end point E of the lane L. For example, an openable / closable flap may be provided at the end point E of the lane L. If the authentication of the target is successful, the control unit 212 may open the closed gate to allow the target to enter the restricted area. Furthermore, if the authentication of the target is unsuccessful, the control unit 212 may restrict the target from entering the restricted area by closing the open gate. Furthermore, for example, the control unit 212 may notify the target of the success or failure of the authentication by illuminating the target's feet with a different color depending on the success or failure of the authentication, thereby controlling the target's entry into the restricted area.

[0064] A security guard may be stationed at the end point E of the lane L. The security guard may call out to a subject who does not perform an action according to the authentication result notified by the control unit 212.

[0065] The target authentication may be performed in a system other than the information processing system S. In this case, the authentication unit 214 may transmit the biometric information to the other system and receive the authentication result from the other system. [2-3: Technical effects of information processing equipment]

[0066] When objects belonging to different groups are moving side by side, the information processing device 2 according to this disclosure can control each of the objects belonging to different groups differently, thereby making it possible to move many objects into the restricted area in a short time without preventing the objects belonging to different groups from moving side by side. [3: Third embodiment]

[0067] A third embodiment of an information processing device, an information processing system, an information processing method, and a program will be described with reference to Figures 8 to 12. Hereinafter, the third embodiment of the information processing device, the information processing system, the information processing method, and the program will be described using an information processing system Sa including an information processing device 3 according to this disclosure. Note that, for the third embodiment, descriptions that overlap with the descriptions of the first and second embodiments will be omitted as appropriate. Also, in the drawings, parts that are common to the second embodiment are indicated by the same reference numerals. [3-1: Configuration of Information Processing System Sa]

[0068] 8, the information processing system Sa includes an information processing device 3, a camera 27, a first camera 281, and a second camera 282. The information processing device 3 may communicate with the camera 27, the first camera 281, and the second camera 282 via a communication device 23. As shown in FIG. 8, the calculation device 21 included in the information processing device 3 may have a tracking unit 211, a control unit 312, an image acquisition unit 213, an authentication unit 214, and a determination unit 216 as logically realized functional blocks or as physically realized processing circuits. [3-2: Information processing method executed by information processing device 3]

[0069] The information processing device 3 is configured as a device for sequentially authenticating objects moving in a movement direction and sequentially controlling the objects' entry into a restricted area. An information processing method executed by the information processing device 3 will be described with reference to Fig. 9 to Fig. 12. Fig. 9 to Fig. 12 are schematic diagrams showing an overview of the information processing method executed by the information processing device 3. [Control example 1]

[0070] The control unit 312 may control the entry of one object into the restricted area by displaying information about the entry of one object moving on one side of the width direction of the lane L into the restricted area on one side in the width direction near the end point E of the lane L. Similarly, the control unit 312 may control the entry of the other object into the restricted area by displaying information about the entry of the other object moving on the other side in the width direction of the lane L into the restricted area on the other side in the width direction near the end point E of the lane L. As illustrated in FIG. 9 , for example, a first display device D1 may be provided on one side in the width direction near the end point E of the lane L, and a second display device D2 may be provided on one side in the width direction near the end point E of the lane L.

[0071] If one of the targets is a target FT whose authentication has failed, the control unit 312 may cause the first display device D1 to display information such as "Do not move to the restricted area" notifying the target that entry into the restricted area is restricted. The control unit 312 may display the notification information together with a facial image of the target FT to make it easier to understand that the notification is intended for the target FT. The information notifying the target that entry into the restricted area is restricted may also be information notifying specific actions that the target should take. For example, if similar authentication is to be performed again in lane L, information such as "Please go back and walk in the lane again" may be notified. Furthermore, if authentication is to be performed again in a location other than lane L (referred to as a "re-authentication area"), information such as "Please move to the re-authentication area" may be notified. In the re-authentication area, for example, authentication by an inspector may be performed. Re-authentication may be performed by authentication other than iris authentication, such as fingerprint authentication or passport verification.

[0072] When performing the same authentication again in lane L, control unit 312 may instruct the target to change the location to which it moves within lane L. For example, if a target moves to one side of the width direction of lane L and fails authentication, control unit 312 may instruct the target to move to the other side of the width direction of lane L. Furthermore, if authentication fails for both a first target that moves to one side of the width direction of lane L and a second target that moves to the other side of the width direction of lane L, control unit 312 may instruct the first target to move to the other side of the width direction of lane L and instruct the second target to move to one side of the width direction of lane L.

[0073] If authentication failures occur repeatedly at the same location, for example, if authentication failures occur a predetermined number of times or more in succession, a worker who performs maintenance on the information processing system may be called.

[0074] If the other target is a target ST who has been successfully authenticated, the control unit 312 may cause the second display device D2 to display information notifying the target that entry into the restricted area is not restricted, such as "Please move to the restricted area." The control unit 312 may cause the notification information to be displayed together with the face image of the other target ST, so that it is easy to understand that the notification is intended for the other target ST.

[0075] 10 illustrates a case where a first target TP1 and a second target TP2 are included in the first group, and authentication of the first target TP1 fails. As illustrated in FIG. 10, the control unit 312 may cause the first display device D1 to display information notifying the target that entry into the restricted area is restricted, such as "Do not move to the restricted area." The control unit 312 may also cause the second display device D2 to display information notifying the target that entry into the restricted area is restricted, such as "Do not move to the restricted area." [Control example 2]

[0076] Two pairs of gates that can be opened and closed may be provided at the end point E of the lane L. In this case, the control unit 312 may control the opening and closing of each of the two pairs of gates to control entry into the target restricted area. The control unit 312 may control each of the two pairs of gates to operate separately. In other words, the control unit 312 may control one gate to open while controlling the other gate to close.

[0077] As illustrated in FIG. 11, in a space in which a first object TP1 and a second object TP2 can move side by side, one side and the other side in a horizontal direction perpendicular to the movement direction may have different appearances. For example, the right and right gates G1 as seen from the object on the floor of lane L may be colored the same color, and the left and left gates G2 as seen from the object on the floor of lane L may be colored the same color. For example, the right and right gates G1 as seen from the object on the floor of lane L may be colored blue, and the left and left gates G2 as seen from the object on the floor of lane L may be colored green. For example, a first pattern may be applied to the right and right gates G1 as seen from the object on the floor of lane L, and a second pattern may be applied to the left and left gates G2 as seen from the object on the floor of lane L.

[0078] 11 illustrates a case where the first target TP1 and the third target TP3 are included in different groups and authentication of the first target TP1 fails. As illustrated in FIG. 11, the control unit 312 may control the gate G1 facing the first target TP1 to close, thereby restricting the first target TP1 from entering the restricted area. The control unit 312 may also control the gate G2 facing the third target TP3, which is included in a different group from the first target TP1, to open, thereby permitting the third target TP3 to enter the restricted area. [Control example 3]

[0079] The control unit 312 may project different images at the feet of the targets depending on whether the authentication was successful. As illustrated in FIG. 12, if one target is a target FT who has failed authentication, the control unit 312 may project an image FI at the feet of the target FT, indicating that entry into the restricted area is restricted. If the other target is a target ST who has successfully authenticated, the control unit 312 may project an image SI at the feet of the other target ST, indicating that entry into the restricted area is permitted. Alternatively, the control unit 312 may emit a directional sound toward the target depending on whether the authentication was successful.

[0080] The control unit 312 may perform at least one of the operations of the above-described control example 1, control example 2, and control example 3. That is, the control unit 312 may perform two or more of the above-described control example 1, control example 2, and control example 3 in combination. [4: Fourth embodiment]

[0081] A fourth embodiment of an information processing device, an information processing system, an information processing method, and a program will be described with reference to Figures 13 and 14. Hereinafter, the fourth embodiment of an information processing device, an information processing system, an information processing method, and a program will be described using an information processing system Sb including an information processing device 4 according to this disclosure. Note that, for the fourth embodiment, descriptions that overlap with the descriptions of the first to third embodiments will be omitted as appropriate. Also, in the drawings, parts common to the second and third embodiments are indicated by the same reference numerals. [4-1: Configuration of information processing system Sb]

[0082] 13, the information processing system Sb includes an information processing device 4, a camera 27, a first camera 281, and a second camera 282. The information processing device 4 may communicate with the camera 27, the first camera 281, and the second camera 282 via the communication device 23. As shown in FIG. 13, the calculation device 21 included in the information processing device 4 may have a tracking unit 411, a control unit 412, an image acquisition unit 213, an authentication unit 414, and a determination unit 416 as logically realized functional blocks or as physically realized processing circuits, as well as a reception unit 415.

[0083] The receiving unit 415 receives input of association information indicating an association between a group and an object included in the group. The receiving unit 415 may receive input of group information indicating that the object is included in a group as the association information. The receiving unit 415 may receive association information that associates information distinguishing groups with distinguishing information distinguishing objects. [4-2: Application example of information processing system Sb]

[0084] The information processing system Sb according to this embodiment may be applied to a location where multiple lanes L are arranged adjacent to each other in the width direction of the lanes L. Fig. 14 illustrates a case where lanes L1, L2, and L3 are arranged adjacent to each other in the width direction.

[0085] In this embodiment, the camera 27 may be provided so as to be able to capture images of a plurality of lanes L. For example, the image acquisition unit 213 may be able to acquire from the camera 27 an image such as that illustrated in FIG.

[0086] The tracking unit 411 may track each of the tracking targets moving in any of the multiple lanes L while associating the target with a group including the target. Although not shown in the figure, the first camera 281 and the second camera 282 may be provided for each lane L. The tracking unit 411 may determine, for each lane L, whether the first camera 281 or the second camera 282 will capture an image. Furthermore, the control unit 412, the authentication unit 414, and the determination unit 416 may operate independently for each lane L.

[0087] Figure 14 illustrates an example where objects TA1 and TA2 moving on lane L1 are included in group A, objects TB1 and TB2 moving on lane L2 are included in group B, objects TC1 moving on lane L1 and objects TC2 moving on lane L3 are included in group C, and object T3 moving on lane L3 is not included in a group (i.e., object T3 is moving alone on lane L).

[0088] That is, each of the targets included in the same group, such as target TC1 and target TC2, may move in a different lane L. For example, even targets included in the same group may move in a different lane L where relatively few people are moving. Targets included in the same group may be instructed by an attendant to move in a different lane L. The tracking unit 411 can track each of the tracking targets included in the same group but moving in different lanes L while associating them with the same group. For example, if authentication of target TC1 fails, the control unit 412 can restrict entry of target TC2 into a restricted area. [4-3: Example of reception operation]

[0089] 14 , for example, the information input device 1000 may be provided behind the start point S of the lane L in the movement direction, and subjects who wish to be managed in group units may input association information to the information input device 1000. In this case, the receiving unit 415 may receive the association information input to the information input device 1000.

[0090] For example, the target may input distinguishing information for distinguishing the target by having a reader included in the information input device 1000 read a signal output from a device the target possesses. Alternatively, the signals output from devices possessed by targets included in the same group may be the same signal. In other words, the targeting information received by the receiving unit 415 may be information that does not allow for distinguishing the target.

[0091] Furthermore, for example, the information input device 1000 may present an overhead image of the area around the information input device 1000 to the subject. The overhead image of the area around the information input device 1000 may include subjects that the subject wishes to manage in groups. The subject may input association information indicating an association between a group and the subjects included in the group by selecting a subject included in a group included in the overhead image of the area around the information input device 1000. The information input device 1000 may generate association information that associates, for example, information distinguishing between groups with upper body feature information of the subject as distinguishing information for distinguishing between the subject. Alternatively, the association information indicating an association between a group and the subjects included in the group may be received by application to an attendant waiting behind the start point S of the lane L in the direction of movement.

[0092] The receiving unit 415 may receive association information other than the association information input to the information input device 1000. For example, the receiving unit 415 may receive association information via the Internet. For example, the receiving unit 415 may receive association information input by the subject using a portable device. Furthermore, the operation of receiving association information may be linked to the operation of checking in for an airplane. [4-4: Technical Effects of Information Processing Device 4]

[0093] The information processing device 4 according to this disclosure can track each of the tracking targets that are included in the same group but move in different lanes L while associating them with the same group. Furthermore, even if a target that is included in the same group but moves in a different lane L fails authentication, the information processing device 4 can restrict the target from entering a restricted area, thereby preventing the targets that are included in the group from losing sight of each other and being unable to act together. [5: Fifth embodiment]

[0094] A fifth embodiment of an information processing device, an information processing system, an information processing method, and a program will be described with reference to Fig. 15. Hereinafter, the fifth embodiment of the information processing device, the information processing system, the information processing method, and the program will be described using an information processing system Sc including an information processing device 5 according to this disclosure. Note that in the drawings, parts common to the second to fourth embodiments are denoted by the same reference numerals.

[0095] 15, the information processing system Sc includes an information processing device 5, a camera 27, a first camera 281, and a second camera 282. The information processing device 5 may communicate with the camera 27, the first camera 281, and the second camera 282 via the communication device 23. As shown in FIG. 15, the arithmetic device 21 included in the information processing device 5 may have a tracking unit 411, a control unit 412, an image acquisition unit 213, an authentication unit 514, a reception unit 515, and a determination unit 416 as logically realized functional blocks or as physically realized processing circuits.

[0096] The reception unit 515 may receive identification information capable of identifying the target as the identification information for distinguishing the target. Examples of the identification information capable of identifying the target include information obtainable from a smartphone carried by the target, information obtainable from an integrated circuit mounted on a passport carried by the target, and information obtainable from a beacon carried by the target. In this case, the authentication unit 514 can perform authentication using the target's identification information in addition to the target's biometric information. The target's identification information may be identification information capable of identifying the target's registered information. Therefore, the authentication unit 514 can compare the target's iris image acquired from the first camera 281 or the second camera 282 with the target's registered information. In other words, the authentication unit 514 can perform one-to-one authentication instead of one-to-many authentication. [Technical Effects]

[0097] The information processing device 5 according to this disclosure can perform one-to-one authentication instead of one-to-N authentication, so that authentication can be completed in a shorter time than in the case of one-to-N authentication, and authentication accuracy can also be improved. [6: Sixth embodiment]

[0098] A sixth embodiment of an information processing device, an information processing system, an information processing method, and a program will be described with reference to FIGS. 16 and 17. Hereinafter, the sixth embodiment of an information processing device, an information processing system, an information processing method, and a program will be described using an information processing system Sd including an information processing device 6 according to this disclosure. Note that, for the sixth embodiment, descriptions that overlap with the descriptions of the first to fifth embodiments will be omitted as appropriate. Furthermore, in the drawings, parts common to the second to fifth embodiments are denoted by the same reference numerals.

[0099] 16, the information processing system Sd includes an information processing device 6, a camera 27, a first camera 281, and a second camera 282. The information processing device 6 may communicate with the camera 27, the first camera 281, and the second camera 282 via a communication device 23. As shown in FIG. 16, the arithmetic device 21 included in the information processing device 6 may have a tracking unit 611, a control unit 412, an image acquisition unit 213, an authentication unit 614, a reception unit 615, and a determination unit 416 as logically realized functional blocks or as physically realized processing circuits.

[0100] As described above, the receiving unit 615 may receive identification information capable of identifying a target as distinguishing information for distinguishing a target. In this case, the authentication unit 614 can perform authentication using the target's identification information in addition to the target's biometric information. The authentication unit 614 can perform both one-to-many authentication and one-to-one authentication. [6-2: Information processing method executed by information processing device 6]

[0101] The information processing device 6 is configured as a device for sequentially authenticating objects moving in a movement direction and sequentially controlling the objects' entry into a restricted area. An information processing method executed by the information processing device 6 will be described with reference to FIG. 17. FIG. 17 is a flowchart showing the flow of the information processing method executed by the information processing device 6. In this flow of the information processing method executed by the information processing device 6, authentication of a first object and a second object included in a first group will be described. Also, in this flow of the information processing method executed by the information processing device 6, the receiving unit 615 receives identification information capable of identifying the objects as distinction information for distinguishing the objects included in the first group.

[0102] 17, the image acquisition unit 213 acquires an image from the camera 27 (step S21). The tracking unit 611 acquires association information that associates information for distinguishing groups with identification information that can identify targets (step S61). The tracking unit 611 associates the tracking target with a group that includes the tracking target (step S23). The authentication unit 614 performs one-to-N authentication of a first target and a second target included in a first group (step S62).

[0103] If the one-to-N authentication of the first target is successful but the one-to-N authentication of the second target is unsuccessful (step S63: Yes), the authentication unit 614 compares the biometric information of the second target with the registration information of targets included in the first group other than the first target (step S64). Note that since the case where the first target and the second target are included in the first group is described, the authentication unit 614 performs one-to-one authentication of the second target. If the one-to-N authentication of the first target and the second target is successful (step S63: No), the flow of the information processing method executed by the information processing device 6 ends. [6-3: Technical Effects of Information Processing Device 6]

[0104] The information processing device 6 according to this disclosure is capable of one-to-one authentication, and therefore can perform re-authentication in a relatively short time after one-to-N authentication has failed. Also, the authentication accuracy can be improved. [7: Seventh embodiment]

[0105] A seventh embodiment relating to an information processing device, an information processing system, an information processing method, and a program will be described. The information processing system according to the seventh embodiment performs the above-described information processing method. The information processing system according to the seventh embodiment may include one or more information processing devices (not shown).

That is, each of the multiple steps included in the above-described information processing method may be performed by a different information processing device. For example, some of the multiple steps included in the above-described information processing method may be performed by a first information processing device, and the remaining steps of the multiple steps included in the above-described information processing method may be performed by a second information processing device.
