Description

[Technical Field]

[0001] The present disclosure relates to a visitor verification device, a visitor verification system, a visitor verification method, and a non-transitory computer-readable medium. [Background technology]

[0002] In facilities such as hospitals, facility staff are often busy dealing with visitors such as outpatients and visitors, and there is a desire to reduce the burden on facility staff. For example, in the medical information management system of Patent Document 1, when an outpatient passes in front of a beacon means installed in the hospital, the beacon means reads the ID number registered in an authentication app installed on a terminal owned by the outpatient and transmits the read ID number to a server.

[0003] In the medical information management system of Patent Document 1, the server sends the ID number and reservation information linked to the ID number to a reception robot and instructs it to process the outpatient's reception. The reception robot requests authentication of the outpatient based on the reservation information linked to the ID number and the reception information entered by the outpatient, and if authentication is successful, it guides the outpatient to the medical office, but if authentication is unsuccessful, it prompts the outpatient to inquire with a facility official.

[0013] Hereinafter, the best mode for carrying out the present disclosure will be described with reference to the accompanying drawings. However, the present disclosure is not limited to the following embodiments. In addition, the following description and drawings have been simplified as appropriate for clarity of explanation.

[0014] <First Embodiment> The visitor verification device and visitor verification method of this embodiment are suitable for verifying visitors to facilities such as hospitals, nursing homes, etc. First, the minimum configuration of the visitor verification device of this embodiment will be described.

[0015] Fig. 1 is a block diagram showing the minimum configuration of a visitor verification device according to this embodiment. As shown in Fig. 1, visitor verification device 1 includes a user information acquisition unit 11, a prospective visitor information registration unit 12, a biometric information acquisition unit 13, an authentication control unit 14, and a control unit 15.

[0016] The user information acquisition unit 11 acquires user information including personal information of the facility user and information about the room used by the user within the facility, and registers the information in an internal or external storage device of the visitor identification device 1. At this time, the personal information of the facility user and the information about the room used by the user may be associated with each other via identification information (such as a user ID) that uniquely corresponds to the personal information of the facility user and the information about the room used by the user within the facility.

[0017] Here, a user is someone who uses the facility continuously or intermittently. For example, if the facility is a hospital, users include medical personnel, office staff, contractors, inpatients, and outpatients. If the facility is a nursing home, users include physical therapists, caregivers, office staff, contractors, residents, and day care recipients.

[0018] The user's personal information may include information indicating the user's name, address and contact information (for example, telephone number, email address, etc.), the names, addresses and contact information of family members, and the names of friends.

[0019] In this case, for example, if the facility is a hospital, the user's personal information may include the patient's medical condition, examination history, scheduled examination date, etc. Also, for example, if the facility is a nursing home, the user's personal information may include the symptoms and rehabilitation history of the residents.

[0020] The room information used by the user in the facility may include information indicating the room number, floor, etc. of the facility used by the user. For example, if the user is an inpatient, the room information used by the user in the facility may include information indicating the room number, bed number, floor, etc. in which the inpatient is admitted. Also, for example, if the user is a resident of a nursing home, the room information used by the user in the facility may include information indicating the room number, bed number, floor, etc. in which the resident occupies.

[0021] The personal information of the user and the room information used by the user within the facility are input, for example, via a terminal installed in the facility or a terminal used by the user. In this case, the user information may preferably include biometric information such as a facial image of the user.

[0022] The wishing visitor information registration unit 12 acquires biometric information of the wishing visitor to the facility and identification information for identifying the user of the facility that the wishing visitor wishes to visit. Here, the wishing visitor is anyone who wishes to visit the facility, excluding users of the facility. For example, if the facility is a hospital, the wishing visitor would be someone who visits an inpatient. Also, if the facility is a nursing home, the wishing visitor would be someone who is visiting a resident.

[0023] The biometric information of the prospective visitor may be any information capable of identifying the individual, such as facial image information, vein image information, or iris information of the prospective visitor. The identification information of the user of the facility the prospective visitor wishes to visit should include at least the user's name. The visitor's biometric information and the identification information for identifying the user of the facility the prospective visitor wishes to visit are input, for example, via a terminal installed at the facility or a terminal owned by the prospective visitor.

[0024] If the specific information of the user of the facility that the visitor wishes to visit matches the information corresponding to the specific information in the user information, the visitor information registration unit 12 registers the visitor information in an internal or external storage device of the visitor verification device 1 as visitor information including biometric information of the visitor to the facility and specific information for identifying the user of the facility that the visitor wishes to visit.

[0025] In this case, the biometric information of the person wishing to visit the facility may be associated with specific information for identifying the user of the facility that the visitor wishes to visit via identification information (such as a visitor ID) that uniquely corresponds to the biometric information of the person wishing to visit the facility and specific information for identifying the user of the facility that the visitor wishes to visit.

[0026] The biometric information acquisition unit 13 acquires the biometric information of visitors to the facility detected by the biometric information detection unit and registers it in a storage device inside or outside the visitor verification device 1. Here, the biometric information detected by the biometric information detection unit is biometric information that corresponds to the biometric information of the person wishing to visit.

[0027] Therefore, the biometric information detection unit may be provided with a sensor capable of detecting biometric information corresponding to the biometric information of the person wishing to visit. Such a biometric information detection unit may be located either inside or outside the facility.

[0028] The authentication control unit 14 controls authentication using the biometric information of the person wishing to visit against the biometric information of the visitor. For example, the authentication control unit 14 performs authentication processing by comparing the biometric information of the visitor with the biometric information of the person wishing to visit. Alternatively, the authentication control unit 14 causes an authentication device to perform authentication processing and obtains the authentication result.

[0029] The control unit 15 controls the mobile object that moves within the facility based on the authentication result. The mobile object is, for example, an autonomous mobile robot.

[0030] Next, the flow of the visitor identification method of this embodiment will be explained. Fig. 2 is a flowchart showing the flow of the visitor identification method of this embodiment. First, the user information acquisition unit 11 acquires and registers user information including personal information and room information of facility users (S1).

[0031] Next, the visitor information registration unit 12 acquires the biometric information of the person wishing to visit the facility and specific information for identifying the user of the facility that the visitor wishes to visit, and determines whether the specific information of the user of the facility that the visitor wishes to visit matches the information in the user information that corresponds to the specific information (S2).

[0032] If there is no match (NO in S2), the would-be visitor information registration unit 12 does not register the biometric information of the would-be visitor to the facility and the identification information for identifying a user of the facility that the would-be visitor wishes to visit. In other words, the would-be visitor information registration unit 12 does not register the would-be visitor information (S3).

[0033] If there is a match (YES in S2), the visitor information registration unit 12 registers the visitor information as visitor information including biometric information of the person wishing to visit the facility and specific information for identifying users of the facility that the visitor wishes to visit (S4).

[0034] Next, the biometric information acquisition unit 13 acquires and registers the biometric information of the visitor to the facility detected by the biometric information detection unit (S5). Then, the authentication control unit 14 controls authentication of the visitor's biometric information using the biometric information of the person wishing to visit (S6), and based on the authentication result, the control unit 15 controls the mobile object moving within the facility (S7).

[0035] In this way, when the specific information of a user of a facility that a visitor wishes to visit matches the information corresponding to that specific information in the user information, the visitor identification device 1 and visitor identification method of this embodiment register the visitor information as visitor information including biometric information of the visitor to the facility and specific information for identifying the user of the facility that the visitor wishes to visit.

[0036] In other words, in the visitor verification device 1 and visitor verification method of this embodiment, if the specific information of the user of the facility that the visitor wishes to visit does not match the information corresponding to that specific information in the user information, the visitor information is not registered and authentication fails.

[0037] As a result, when a visitor whose intended visitor information is not registered comes to a facility, the visitor identification device 1 and visitor identification method of this embodiment can recognize that the visitor may be a suspicious person. Therefore, the visitor identification device 1 and visitor identification method of this embodiment can recognize the intrusion of a suspicious person into a facility before it happens.

[0038] The visitor verification device 1 includes a processor, memory, and storage device (not shown). The storage device stores a computer program that implements the process of the visitor verification method according to this embodiment. The processor then loads the computer program from the storage device into the memory and executes the computer program. This allows the processor to implement the functions of a user information acquisition unit 11, a prospective visitor information registration unit 12, a biometric information acquisition unit 13, an authentication control unit 14, and a control unit 15.

[0039] Alternatively, each component of the visitor verification device 1 may be realized by dedicated hardware. Furthermore, some or all of the components of each device may be realized by general-purpose or dedicated circuits, processors, etc., or a combination of these. These may be configured by a single chip, or by multiple chips connected via a bus. Some or all of the components of each device may be realized by a combination of the above-mentioned circuits and programs. Furthermore, processors such as CPUs (Central Processing Units), GPUs (Graphics Processing Units), FPGAs (Field-Programmable Gate Arrays), and quantum processors (quantum computer control chips) can be used.

[0040] Furthermore, when some or all of the components of visitor identification device 1 are realized by multiple processing devices or circuits, the multiple processing devices or circuits may be centrally or decentralized. For example, the processing devices and circuits may be realized as a client-server system, cloud computing system, or other system connected via a communications network. Furthermore, the functions of visitor identification device 1 may be provided in the form of SaaS (Software as a Service).

[0041] <Embodiment 2> This embodiment is a specific example of the above-mentioned embodiment 1. Fig. 3 is a block diagram showing the configuration of a visitor identification system of this embodiment. As shown in Fig. 3, the visitor identification system 1000 includes a first terminal 100, a second terminal 200, a mobile object 300, an authentication device 400, and a visitor identification device 500.

[0042] The first terminal 100, second terminal 200, mobile object 300, authentication device 400, and visitor verification device 500 are all connected via a network N. Here, the network N is a wired or wireless communication line, such as the Internet.

[0043] The visitor identification system 1000 of this embodiment is configured to be able to guide visitors to the hospital room or other location they are visiting, and to recognize suspicious individuals, based on the authentication results of visitors to a hospital, which is a typical example of a facility.

[0044] In this embodiment, authentication will be described as face authentication, which is an example of biometric authentication, and facial feature information, which is an example of biometric information. However, other technologies that use captured images of individuals can be applied to biometric authentication and biometric information. For example, data (features) calculated from the physical features of an individual, such as fingerprints, voiceprints, veins, retinas, irises, or palm patterns, may be used as biometric information.

[0045] The first terminal 100 is, for example, a smartphone, tablet terminal, or personal computer installed in a hospital, and is operated by a medical professional or office worker at the hospital. Fig. 4 is a block diagram showing the configuration of the first terminal in the visitor identification system of this embodiment.

[0046] 4, the first terminal 100 includes an input unit 110 and a communication unit 120. The input unit 110 is, for example, a touch panel or a keyboard, and receives input of personal information of the user and information about the room used by the user in the hospital. The communication unit 120 is connected to a network N.

[0047] The second terminal 200 is, for example, a smartphone, tablet terminal, or personal computer owned by the person wishing to visit the hospital, and is operated by the person wishing to visit. Fig. 5 is a block diagram showing the configuration of the second terminal in the visitor identification system of this embodiment. As shown in Fig. 5, the second terminal 200 includes a camera 210, an input unit 220, and a communication unit 230.

[0048] The camera 210 captures the face of the person wishing to visit. The input unit 220 is, for example, a touch panel or a keyboard, and accepts input of the personal information of the person wishing to visit and specific information for identifying the hospitalized patient that the person wishing to visit wishes to visit.

[0049] Here, the personal information of the wishing visitor may include, for example, information indicating the name, address, and contact information of the wishing visitor. Furthermore, the specific information for identifying the hospitalized patient whom the wishing visitor wishes to visit may include, for example, information indicating the hospitalized patient's name and room number. The communication unit 230 is connected to the network N.

[0050] Mobile body 300 is a robot that moves autonomously within a hospital. Fig. 6 is a block diagram showing the configuration of a mobile body in the visitor identification system of this embodiment. As shown in Fig. 6, mobile body 300 includes a display unit 310, an input unit 320, a camera 330, a drive unit 340, a communication unit 350, and a control unit 360.

[0051] The display unit 310 is, for example, a liquid crystal display, and displays questions for visitors (for example, "If you are visiting someone in the hospital, please touch the display to start the tour," "Do you want to end the tour? YES, NO"), etc.

[0052] Input unit 320 is, for example, a touch panel stacked on display unit 310, and receives responses to inquiries from visitors. When it is confirmed that a visitor has touched a display indicating the start of guidance via input unit 320, camera 330 is activated and takes a picture of the visitor's face.

[0053] The driving unit 340 is a motor or the like for moving the mobile body. The communication unit 350 is connected to the network N. The control unit 360 controls the camera 330 based on input information from the input unit 320, and controls the driving unit 340 based on control information from the visitor identification device 500, as will be described later.

[0054] The authentication device 400 manages the facial image information of the prospective visitor. Based on the facial authentication request information received from the visitor identification device 500, the authentication device 400 compares the facial image information of the visitor included in the facial authentication request information with the facial image information of the prospective visitor, and transmits the comparison result (authentication result) information to the visitor identification device 500.

[0055] Fig. 7 is a block diagram showing the configuration of an authentication device in the visitor identification system of this embodiment. As shown in Fig. 7, the authentication device 400 includes a face information DB (DataBase) 410, a feature point extraction unit 420, a registration unit 430, an authentication unit 440, and a communication unit 450. The face information DB 410 stores a personal ID 411 in association with facial feature information 412 for that personal ID. The facial feature information 412 is a collection of feature points extracted from facial image information.

[0056] The authentication device 400 may delete the facial feature information 412 from the facial information DB 410 in response to a request from the prospective visitor corresponding to the facial feature information 412. Alternatively, the authentication device 400 may delete the facial feature information 412 after a certain period of time has elapsed since registration.

[0057] The feature point extraction unit 420 extracts feature points from the facial image information of the person wishing to visit, and outputs facial feature information 412 to the registration unit 430. The feature point extraction unit 420 also extracts feature points from the facial image information of the visitor, and outputs the facial feature information to the authentication unit 440.

[0058] When registering the facial feature information, the registration unit 430 issues a new personal ID 411. The registration unit 430 associates the issued personal ID 411 with facial feature information 412 extracted from the facial image information of the prospective visitor and registers them in the facial information DB 410.

[0059] The authentication unit 440 performs face authentication using the facial feature information 412. Specifically, the authentication unit 440 compares the facial feature information extracted from the visitor's facial image information with the facial feature information 412 in the facial information DB 410. If the comparison is successful, the authentication unit 440 identifies the personal ID 411 associated with the compared facial feature information 412.

[0060] The authentication unit 440 transmits the presence or absence of a match in the facial feature information as a facial authentication result to the visitor verification device 500. Here, the presence or absence of a match in the facial feature information corresponds to the success or failure of authentication. Note that a match in the facial feature information (match present) refers to a case where the degree of match is equal to or greater than a threshold. Furthermore, if facial authentication is successful, the facial authentication result includes the identified personal ID. The communication unit 450 is connected to the network N.

[0061] The visitor verification device 500 performs processes such as registering information about prospective visitors, authenticating and controlling visitors, and controlling the mobile object 300. The visitor verification device 500 may be configured redundantly across multiple servers, and each functional block may be implemented by multiple computers.

[0062] 8 is a block diagram showing the configuration of a visitor identification device in the visitor identification system of this embodiment. As shown in FIG. 8, visitor identification device 500 includes storage unit 510, memory 520, processing unit 530, and communication unit 540.

[0063] The storage unit 510 is an example of a storage device such as a hard disk, a flash memory, an SSD, etc. The storage unit 510 stores a program 511, user information 512, information on prospective visitors 513, and facial image information 514 of visitors.

[0064] The program 511 is a computer program that implements the process of the visitor identification method of this embodiment. The user information 512 is, for example, personal information of the user that the user inputs via the first terminal 100 and information about the room that the user uses in the hospital.

[0065] The visitor information 513 is information that associates, for example, a visitor ID 513a, personal information 513b of the visitor, facial image information 513c of the visitor, and identification information 513d for identifying the hospitalized patient that the visitor wishes to visit.

[0066] Here, the would-be visitor ID 513a is identification information of the would-be visitor. The would-be visitor ID 513a is information that is identical to or uniquely corresponds to the individual ID 411 that is associated with the facial feature information 412 and managed in the face information DB 410 of the authentication device 400. Therefore, the would-be visitor information 513 can be said to be information that is associated with the visitor's personal authentication information (biometric information) for authenticating the visitor via the would-be visitor ID 513a.

[0067] The personal information 513b of the person wishing to visit, the facial image information 513c of the person wishing to visit, and the specific information 513d for identifying the hospitalized patient whom the visitor wishes to visit are the personal information of the person wishing to visit, the facial image information of the person wishing to visit, and the specific information for identifying the hospitalized patient whom the visitor wishes to visit, entered by the visitor via the second terminal 200.

[0068] The visitor's face image information 514 is information about the visitor's face image photographed by the camera 330 of the mobile object 300 when the visitor visits the hospital.

[0069] Memory 520 is a volatile storage device such as RAM (Random Access Memory), and is a storage area for temporarily storing information during operation of processing unit 530. Processing unit 530 is a processor, or processing device, that controls each component of visitor verification device 500.

[0070] The processing unit 530 loads the program 511 from the storage unit 510 into the memory 520 and executes the program 511. As a result, the processing unit 530 realizes the functions of a user information acquisition unit 531, an applicant visitor information registration unit 532, a biometric information acquisition unit 533, an authentication control unit 534, and a control unit 535.

[0071] The user information acquisition unit 531 acquires user information 512 and registers it in the storage unit 510. If the identification information for identifying the hospitalized patient that the wishing visitor wishes to visit matches the information corresponding to the identification information in the user information 512, the desirer visitor information registration unit 532 registers the desirer visitor information 513 in the storage unit 510 as desirer visitor information 513 including personal information 513b, facial image information 513c, and identification information 513d.

[0072] At this time, would-be visitor information registration section 532 includes the facial image information included in would-be visitor information 513 in facial information registration request information and transmits it to authentication device 400, and receives personal ID 411 issued by authentication device 400.

[0073] Then, the wishing visitor information registration unit 532 generates wishing visitor information 513 by associating the received individual ID 411 as a wishing visitor ID 513a with personal information 513b, facial image information 513c, and identification information 513d, and registers this in the storage unit 510.

[0074] The biometric information acquisition unit 533 acquires the visitor's facial image information photographed via the camera 330 of the mobile object 300 when the visitor visits the hospital, and registers the acquired information in the storage unit 510. The authentication control unit 534 controls facial authentication for the visitor's facial image information 514. Specifically, the authentication control unit 534 transmits facial authentication request information including the facial image information 514 to the authentication device 400, and receives facial authentication result information from the authentication device 400.

[0075] The authentication control unit 534 then determines whether authentication has been successful based on the face authentication result information received from the authentication device 400, and if authentication is successful, identifies the visitor as an applicant for visit. The authentication control unit 534 may also detect the visitor's face area from the face image information 514 and include image information of the face area in the face authentication request information. Alternatively, the authentication control unit 534 may extract facial feature information from the face area and include the facial feature information in the face authentication request information.

[0076] If the authentication is successful, the control unit 535 generates control information for controlling the mobile object 300 to guide the visitor to the hospital room of the hospitalized patient that the visitor wishes to visit. On the other hand, if the authentication is unsuccessful, the control unit 535 generates control information for controlling the mobile object 300 to guide the visitor to a first predetermined location in the hospital (for example, the reception desk or the security room). The communication unit 540 is connected to the network N.

[0077] Next, the flow of the visitor identification method of this embodiment will be described. Figs. 9 and 10 are flowcharts showing the processing of the visitor identification method of this embodiment. Fig. 11 is a diagram showing how a person wishing to visit inputs personal information and the like via a second terminal. Fig. 12 is a diagram showing how a visitor inputs the start of guidance via an input unit of a mobile object. Fig. 13 is a diagram showing how a mobile object guides a visitor. Fig. 14 is a diagram showing the state when the mobile object has finished guiding the visitor to a room.

[0078] Here, it is assumed that user information 512 is already stored in memory unit 510 of visitor identification device 500. However, user information 512 may be registered in an existing hospital system or the like, and may be acquired when the visitor identification method described below is performed.

[0079] 11, the would-be visitor P1 first inputs the would-be visitor P1's personal information, facial image information of the would-be visitor P1, and specific information for identifying the hospitalized patient whom the would-be visitor P1 wishes to visit via the second terminal 200, and this information is acquired by the second terminal 200. The would-be visitor information registration unit 532 of the visitor identification device 500 then receives registration request information including the would-be visitor P1's personal information, facial image information of the would-be visitor P1, and specific information for identifying the hospitalized patient whom the would-be visitor P1 wishes to visit from the second terminal 200 via the network N (S11).

[0080] Next, the visitor information registration unit 532 determines whether the specific information used to identify the hospitalized patient that the visitor P1 wishes to visit matches the information corresponding to the specific information contained in the user information 512 (S12).

[0081] For example, the visitor information registration unit 532 determines whether the name and room number of the hospitalized patient included in the identification information for identifying the hospitalized patient that the visitor P1 wishes to visit match the name and room number of the hospitalized patient included in the user information 512.

[0082] If there is a match (YES in S12), the would-be visitor information registration unit 532 extracts facial image information of the would-be visitor P1 from the registration request information and transmits facial image registration request information including the facial image information to the authentication device 400 via the network N (S13). In response, the authentication device 400 performs a facial image registration process.

[0083] In detail, when the authentication device 400 receives facial image registration request information from the visitor verification device 500 via the network N, the feature point extraction unit 420 of the authentication device 400 extracts feature points (facial feature information 412) from the facial image information included in the facial image registration request information.

[0084] Then, registration unit 430 of authentication device 400 issues a personal ID 411, associates the extracted facial feature information 412 with the issued personal ID 411, and registers them in face information DB 410. Thereafter, registration unit 430 of authentication device 400 transmits the issued personal ID 411 to visitor verification device 500.

[0085] Next, the would-be visitor information registration unit 532 receives the personal ID 411 issued in response to the registration of the facial image information from the authentication device 400 (S14). Then, the would-be visitor information registration unit 532 generates would-be visitor information 513 that associates the received personal ID 411 as a visitor ID 513a with personal information 513b, facial image information 513c, and identification information 513d, and registers this in the storage unit 510 (S15).

[0086] On the other hand, if there is no match (NO in S12), the wishing visitor information registration unit 532 does not register the wishing visitor's personal information, facial image information of the wishing visitor, and specific information for identifying the hospitalized patient the wishing visitor wishes to visit in the memory unit 510; in other words, the wishing visitor information registration unit 532 does not register the wishing visitor information in the memory unit 510 (S16).

[0087] The wishing visitor information registration unit 532 may return a message indicating that registration has been completed or that registration has failed to the second terminal 200 via the network N. In this case, the second terminal 200 may display the received message indicating that registration has been completed or that registration has failed on its screen.

[0088] 12, when visitor P2 visits the hospital and inputs a command to start guidance via input unit 320 of mobile object 300, camera 330 of mobile object 300 takes a facial image of visitor P2 and transmits the facial image information to visitor identification device 500 via network N (S17). At this time, mobile object 300 is assumed to be waiting at the entrance (reception) of the hospital, for example.

[0089] Next, upon receiving the facial image information, the biometric information acquisition unit 533 of the visitor verification device 500 acquires the facial image information of visitor P2 and registers it in the storage unit 510 (S18). The authentication control unit 534 of the visitor verification device 500 then transmits facial authentication request information including the facial image information to the authentication device 400, and receives facial authentication result information from the authentication device 400 (S19).

[0090] In detail, when the authentication device 400 receives face authentication request information from the visitor verification device 500 via the network N, the feature point extraction unit 420 of the authentication device 400 extracts face feature information from the face image information included in the face authentication request information.

[0091] Next, the authentication unit 440 of the authentication device 400 compares the facial feature information extracted from the facial image information included in the facial authentication request information with the facial feature information 412 in the facial information DB 410, and calculates the degree of match. Then, the authentication unit 440 determines whether the degree of match is equal to or greater than a threshold.

[0092] If the facial feature information matches, that is, if the degree of match between the facial feature information is equal to or greater than a threshold, the authentication unit 440 identifies the personal ID 411 associated with the facial feature information 412. The authentication unit 440 then returns facial authentication result information, including the identified personal ID 411 and a notification that facial authentication was successful, to the visitor verification device 500 via the network N.

[0093] On the other hand, if the degree of match of the facial feature information is less than the threshold, the authentication unit 440 returns facial authentication result information, including a message to the effect that facial authentication has failed, to the visitor verification device 500 via the network N.

[0094] The authentication control unit 534 of the visitor verification device 500 determines whether or not face authentication has been successful based on the face authentication result information received from the authentication device 400 via the network N (S20). If face authentication has been successful (YES in S20), the authentication control unit 534 identifies the personal ID 411 included in the face authentication result information as the visitor ID 513a (S21). In other words, the authentication control unit 534 authenticates that the intending visitor P1 and visitor P2 are the same person.

[0095] Next, the control unit 535 of the visitor confirmation device 500 generates control information for controlling the mobile object 300 to guide the visitor P2 to the hospital room of the hospitalized patient that the visitor P2 wishes to visit, based on the identification information 513d associated with the visitor ID 513a in the wishing visitor information 513, and transmits the control information to the mobile object 300 via the network N (S22). Note that the control unit 535 may refer to the user information 512 as appropriate.

[0096] Next, the control unit 360 of the moving body 300 controls the driving unit 340 based on the control information, and guides the visitor P2 to the hospital room of the hospitalized patient that the visitor P2 wishes to visit, as shown in FIG. 13 (S23).

[0097] In this case, it is preferable that the mobile body 300 is provided with a support part for supporting the visitor P2, such as a handle to be held by the visitor P2. This allows the visitor P2 to be safely guided to the hospital room, even if the visitor P2 is elderly.

[0098] Then, when mobile object 300 arrives at the hospital room of the hospitalized patient that visitor P2 wishes to visit, as shown in Fig. 14, control unit 360 of mobile object 300 generates control information to display a query such as "Do you want to end the tour? YES, NO" on display unit 310. Display unit 310 of mobile object 300 displays the query based on the control information.

[0099] The control unit 360 of the mobile object 300 determines whether visitor P2 has input YES or NO via the input unit 320 of the mobile object 300 (S24). If YES has been input (YES in S24), the control unit 360 of the mobile object 300 transmits input information indicating that YES has been input to the visitor identification device 500 via the network N. This causes the visitor identification device 500 to end the identification process.

[0100] On the other hand, if NO is entered (NO in S24) because, for example, the hospitalized patient that visitor P2 wishes to visit is not in the hospital room, the control unit 360 of the mobile body 300 transmits input information indicating that NO has been entered to the visitor identification device 500 via the network N.

[0101] Then, the control unit 535 of the visitor identification device 500 generates control information for controlling the mobile body 300 to guide the visitor P2 to a second location where the visitor can kill time, such as a cafe area in a hospital, and terminate the guidance process, and transmits the control information to the mobile body 300 via the network N (S25).

[0102] Thereafter, the control unit 360 of the mobile body 300 controls the driving unit 340 based on the control information, and guides the visitor P2 to a second location where the mobile body 300 can kill time, and the visitor identification device 500 ends the identification process.

[0103] If facial authentication fails (NO in S20), the control unit 535 of the visitor identification device 500 generates control information to cause the mobile body 300 to guide the visitor P2 to a predetermined first location within the hospital, and transmits the control information to the mobile body 300 via the network N (S26).

[0104] Thereafter, the control unit 360 of the mobile body 300 controls the drive unit 340 based on the control information, and when the mobile body 300 guides the visitor P2 to a first predetermined location within the hospital, the visitor identification device 500 ends the identification process.

[0105] In this way, in the visitor identification system 1000, visitor identification device 500, and visitor identification method of this embodiment, if the specific information of a user of a facility that a visitor wishes to visit matches the information corresponding to that specific information in the user information, the visitor information is registered as visitor information including personal information of the visitor, facial image information of the visitor, and specific information for identifying the user of the facility that the visitor wishes to visit.

[0106] In other words, in the visitor identification system 1000, visitor identification device 500, and visitor identification method of this embodiment, if the specific information of a user of the facility that the visitor wishes to visit does not match the information corresponding to that specific information in the user information, the visitor information is not registered and authentication fails.

[0107] As a result, visitor identification system 1000, visitor identification device 500, and visitor identification method of the present embodiment can recognize that a visitor whose intended visitor information is not registered may be a suspicious person when he or she visits a facility. Therefore, visitor identification system 1000, visitor identification device 500, and visitor identification method of the present embodiment can recognize in advance the intrusion of a suspicious person into a facility.

[0108] Furthermore, the visitor identification system 1000, visitor identification device 500, and visitor identification method of this embodiment can contribute to improving safety within the facility, as the mobile object 300 guides visitor P2 to a first location within the facility if authentication fails.

[0109] Furthermore, in the visitor identification system 1000, visitor identification device 500, and visitor identification method of the present embodiment, if authentication is successful, for example, the mobile object 300 guides the visitor P2 to the hospital room of the hospitalized patient that the visitor P2 wishes to visit. This reduces the workload of, for example, hospital office staff, who must guide the visitor P2 to the hospital room.

[0110] Here, when guiding visitor P2 to a destination such as a hospital room, the display unit 310 of the mobile body 300 may display destination information, arrow guidance information when approaching a fork in the road, or route information to the destination on a floor plan of the facility.

[0111] In this case, the moving body 300 in this embodiment is equipped with one display unit 310, but the moving body 300 may be equipped with a display unit 310 on both the front and rear sides thereof. If the moving body 300 is equipped with a surrounding environment detection unit, it is preferable to determine whether the visitor P2 is in front or behind the moving body 300, and control the display unit 310 on the front or rear side according to the position of the visitor P2 relative to the moving body 300. This makes it possible to prevent the visitor P2 from coming into contact with the moving body 300.

[0112] <Third Embodiment> 15 is a block diagram showing the configuration of a visitor identification system according to the present embodiment. Visitor identification system 1001 according to the present embodiment has substantially the same configuration as visitor identification system 1000 according to the first embodiment, but is configured such that, if authentication fails, an external notification is sent to the effect that authentication of visitor P2 has failed, i.e., that an abnormality has occurred.

[0113] The rest of the configuration of visitor identification system 1001 is the same as that of visitor identification system 1000 of the first embodiment, so duplicated explanations will be omitted and the same elements will be described using the same reference numerals.

[0114] 16 is a block diagram showing the configuration of a visitor identification device in a visitor identification system according to the present embodiment. In visitor identification system 1001 according to the present embodiment, visitor identification device 501 includes notification unit 550, as shown in FIG.

[0115] If the authentication fails, the notification unit 550 notifies the third terminal 600 that authentication of visitor P2 has failed. The third terminal 600 is, for example, a smartphone, tablet terminal, or personal computer installed in an office or security room of a facility, and is connected to the network N.

[0116] This allows a facility staff member or security guard to quickly recognize that visitor P2 who has failed authentication may be a suspicious person. The third terminal 600 may be the same as the first terminal 100.

[0117] However, the notification unit 550 may be configured to notify the outside that an abnormality has occurred, and may, for example, notify the outside from a speaker of the moving object 300 that an abnormality has occurred.

[0118] <Fourth Embodiment> In the above-described first to third embodiments, for example, if a command to start guidance is not input within a preset period via the input unit 320 of the mobile object 300, the mobile object 300 may be configured to patrol within the facility. In this case, the user information includes, for example, facial image information of the user, and the personal ID of the user is stored in the face information DB 410 of the authentication device 400 in association with the personal information, room information, and facial feature information of the user.

[0119] 17 is a flowchart showing the processing performed when a mobile object travels around a facility. The control unit 535 of the visitor identification device 500 determines whether or not a guidance start input has been received via the input unit 320 of the mobile object 300 within a preset period of time (S31).

[0120] If an input to start guidance has been received (YES in S31), the visitor identification device 500 executes the processes from S17 onwards in embodiment 2. On the other hand, if an input to start guidance has not been received (NO in S31), the control unit 535 of the visitor identification device 500 generates control information to cause the camera 330 to capture images of the inside of the facility while the mobile object 300 patrols the facility, and transmits this control information to the mobile object 300 via the network N (S32).

[0121] Next, the control unit 360 of the mobile object 300 controls the driving unit 340 based on the control information, and also controls the camera 330. As a result, the mobile object 300 takes images of the inside of the facility while patrolling the facility, and transmits the image information to the visitor identification device 500 via the network N (S33).

[0122] Next, upon receiving the image information, the authentication control unit 534 of the visitor verification device 500 transmits facial authentication request information including the image information to the authentication device 400, and receives facial authentication result information from the authentication device 400 based on the result of matching the facial feature information extracted from the image information with the facial feature information of the user stored in the facial information DB 410 (S34).

[0123] The authentication control unit 534 of the visitor verification device 500 determines whether or not face authentication has been successful based on the face authentication result information received from the authentication device 400 via the network N (S35). If face authentication has been successful (YES in S35), the control unit 535 of the visitor verification device 500 determines whether or not the mobile object 300 has reached the starting point (for example, an entrance / exit of a facility) (S36).

[0124] If the mobile object 300 has reached the starting point (YES in S36), the control unit 535 of the visitor identification device 500 returns to step S31. On the other hand, if the mobile object 300 has not reached the starting point (NO in S36), the control unit 535 of the visitor identification device 500 generates control information to allow the mobile object 300 to continue patrolling within the facility, and returns to step S33.

[0125] If face authentication fails (NO in S35), the control unit 535 of the visitor identification device 500 generates control information to cause the mobile object 300 to guide the visitor whose face authentication failed to a first location within the facility, and transmits this control information to the mobile object 300 via the network N (S37). The control unit 535 of the visitor identification device 500 then proceeds to step S36.

[0126] As a result, in this embodiment, it is possible to quickly detect people other than facility users who have entered the facility, thereby improving safety within the facility.

[0127] In this embodiment, a person who has failed authentication is guided to a first location within the facility, but the fact that the authentication has failed may be notified to the outside as in embodiment 3. In this case, current location information of the mobile object 300 may be transmitted to the third terminal 600 in the facility together with abnormality occurrence information indicating that the authentication has failed.

[0128] Furthermore, in this embodiment, facial authentication is performed, but as described above, data calculated from the physical characteristics of an individual may also be used. Furthermore, biometric information of users such as medical personnel and office workers may be registered in advance, and may be registered so that guidance is not provided even if authentication is successful. Furthermore, users such as medical personnel and office workers may be identified based on their clothing, and those identified as such users may not be guided.

[0129] The present disclosure is not limited to the above-described embodiments, and may be modified as appropriate without departing from the spirit and scope of the present disclosure. In addition, the present disclosure may be implemented by appropriately combining the respective embodiments.

[0130] For example, a registration period for the wishing visitor information 513 in the memory unit 510 may be set in advance, and the wishing visitor information registration unit 532 of the visitor confirmation device 500, 501 may notify the second terminal 200 that the registration of the wishing visitor information 513 will be deleted before the registration period expires.

[0131] For example, when guiding a visitor to an inpatient's hospital room via the mobile object 300, if the user information includes electronic medical record information including the date and time of the inpatient's examination, the visitor identification devices 500, 501 may refer to the user information and control the mobile object 300 to guide the visitor to a second location where the inpatient can kill time, such as a cafe area in the hospital, if the inpatient is absent from the hospital room due to an examination, etc. The visitor identification devices 500, 501 may also determine whether visiting hours are available, and control the mobile object 300 to guide the visitor to the second location if it is outside of visiting hours.

[0132] For example, the visitor management system may be configured such that a biometric information detector that detects the visitor's biometric information is installed in a gate installed at the entrance / exit of the facility, and if authentication is successful, the gate opens and a robot guides the visitor to the destination. In this case, the entry and exit of visitors may be managed by obtaining the time when the visitor passes through the gate.

[0133] A part or all of the above-described embodiment can be described as, but is not limited to, the following supplementary notes. (Appendix 1) a user information acquisition means for acquiring user information including personal information and room information of facility users; a wishing visitor information registration means for acquiring biometric information of the wishing visitor to the facility and specific information for identifying a user of the facility whom the wishing visitor wishes to visit, and, if the specific information matches information corresponding to the specific information in the user information, registering the wishing visitor information as wishing visitor information including the biometric information and the specific information of the wishing visitor; a biometric information acquisition means for acquiring biometric information of a visitor to the facility detected by the biometric information detection means; an authentication control means for controlling a first authentication using the biometric information of the person wishing to visit with respect to the biometric information of the visitor; a control means for controlling a moving object that moves within the facility based on a result of the first authentication; A visitor verification device comprising:
