Description

[Technical Field]

[0001] The present invention relates to a measurement terminal and a server that measure vital information of a subject in a non-contact manner. [Background technology]

[0002] Conventionally, there is known a measurement system that uses a measurement terminal to measure vital information of a person to be measured in a non-contact manner, transmits the measurement results to a server, and manages the results in association with the person as data of the person to be measured (for example, Patent Document 1).

[0003] In such measurement systems, the person being measured is sometimes identified using a facial image of the person being measured. In this case, when the person is measured for the first time, a photograph of the person being measured is taken using a measurement terminal and the facial image is registered on a server (face registration process). After that, the server is accessed from a PC or other device and information such as the person's name and age that will be linked to the registered facial image is entered (management console process).

[0004] Such measurement systems are also being used in conjunction with existing external systems, such as those owned by hospitals, nursing homes, and sports gyms that require vital sign information. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2020-046962 Summary of the Invention [Problem to be solved by the invention]

[0006] In the conventional technology, even when the above-mentioned measurement system is used in conjunction with an external system, it is necessary to perform face registration operations using a measurement terminal and management console operations using a personal computer or the like.

[0007] When information such as the name and date of birth of the person being measured is input from the external system, the server refers to the information registered in the face registration work and management console work to identify the person being measured whose date of birth matches, and provides the identification ID of the identified person to the external system. Thereafter, the external system can obtain the measurement results, etc. managed by the server by sending a data request including the identification ID to the server.

[0008] However, for measurement operators who know that information such as the subject's name and date of birth is already registered in the external system, the task of entering the name, date of birth, etc. into the management console in order to link with the measurement system is nothing but a cumbersome task.

[0009] One aspect of the present invention has been made in consideration of the above-mentioned problems, and aims to provide a server and a measurement terminal that can link a measurement system with an external system with simple operations. [Means for solving the problem]

[0010] In order to solve the above problems, a server according to one embodiment of the present invention is a server that receives measurement values ​​of vital information of a person being measured from a measurement terminal and manages the vital information, and is equipped with an information acquisition unit that acquires, from a linked external system, subject information for multiple subjects registered in the system, the subject information including at least a subject face image, which is a facial image of the subject himself / herself, and the subject's name; a linking processing unit that, when a subject face image, which is a facial image of the person being measured, is received from the measurement terminal, performs at least facial authentication with the multiple subject face images and links the subject information of the subject corresponding to the subject face image to the subject face image; and a registration processing unit that registers the subject face image and the linked subject information.

[0011] In order to solve the above problem, a measurement terminal according to one embodiment of the present invention is a measurement terminal that photographs a person being measured, measures the vital information of the person being measured based on the photographed image, and transmits the measurement value to a server, and has a face registration image transmission processing unit that accepts a registration operation to register the person being measured on the server, and transmits a face registration image, which is a photographed face image of the person being measured, to the server, and a display processing unit that, when registration-related information including information about a subject to be linked to the face registration image is received from the server, displays a screen corresponding to the received information.

[0012] In order to solve the above problem, a measurement terminal according to one embodiment of the present invention is a measurement terminal that photographs a person being measured, measures the vital information of the person being measured based on the photographed image, and transmits the measurement value to a server, and has a measurement processing unit that accepts the photograph of the person being measured and transmits to the server a facial authentication image which is a photographed image of the person being measured, and the measurement value measured based on the photographed image, and a display processing unit that displays a screen corresponding to the received information when a measurement result based on the measurement value is received from the server, and when the display processing unit receives from the server information including the name of the subject to be linked to the facial authentication image, it displays a confirmation screen that prompts the person being measured to confirm that the person has that name, and the measurement terminal further has a confirmation result transmission processing unit that transmits the confirmation result received on the confirmation screen to the server.

[0016] [Embodiment 1] Hereinafter, one embodiment of the present invention will be described in detail.

[0017] (1. Linking System) The configuration of a linking system 1 including a server 200 and a measurement terminal 100 according to the first embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing an example of the configuration of a linking system 1 including a server 200 and a measurement terminal 100 according to the first embodiment.

[0018] 1, the association system 1 includes a measurement terminal 100, a server 200, and an external system 300, and the measurement terminal 100 and the server 200, and the server 200 and the external system 300 can be connected via a network N. The server 200 can also be connected to an input terminal 400 via the network N.

[0019] The measurement terminal 100 is a device used to measure vital information of a person being measured based on a captured image of the person being measured (i.e., without contact). The vital information includes the person's temperature, blood vessel information, heart rate information, etc. The measurement terminal 100 may also be capable of acquiring biological information other than vital information. The measurement terminal 100 may be any device that has the function of acquiring and displaying images, and may be, for example, a smartphone or tablet terminal.

[0020] The measurement worker measures the vital information of the person being measured by photographing the person being measured while checking an image including the person being measured displayed on the screen using the measurement terminal 100. Such a measurement terminal 100 is used, for example, in a care setting when a caregiver (measurement worker) measures the vital information of a person being cared for (person being measured).

[0021] The functions of the measurement terminal 100 described below can also be realized by installing a program on a general-purpose computer. The program can also be called application software. In the following, an example will be described in which the measurement terminal 100 is a smartphone on which the program is installed.

[0022] The server 200 is a device that receives measurement values ​​of vital information of the subject from the measurement terminal 100 and manages the vital information. The measurement terminal 100 and the server 200 constitute a measurement system.

[0023] The external system 300 is a system provided in a facility that has registered for linkage, such as a hospital, a nursing home, or a sports gym that requires vital sign information.

[0024] The input terminal 400 is a personal computer or the like on the user side of the measurement terminal 100, and is a device used for management console operations to register the subject's information (described later), such as the subject's name, in the server 200. Note that the measurement terminal 100 may be equipped with a function to accept management console operations, and the measurement terminal 100 may be used to perform management console operations.

[0025] In order to manage the vital information measured by the measurement terminal 100 on the server 200, first, a face registration operation is performed to register a facial photograph of the subject on the server 200. Then, a management console operation is performed to register the subject's information, such as the subject's name, on the server 200.

[0026] In the linking system 1, even if the person being measured is an unregistered person not registered in the server 200, if the person is registered in the external system 300 and information such as the person's name including a photograph of their face is stored in the external system 300, this data can be registered in the server 200 as person being measured information.

[0027] Therefore, when a measurement system consisting of the measurement terminal 100 and the server 200 is introduced into a facility equipped with the external system 300, the data registered in the external system 300 can be used, simplifying the registration process during linkage. Specifically, the number of items to be entered in the management console process is reduced, and if all of the subject information to be entered in the management console process is stored in the external system 300, the management console process itself becomes unnecessary.

[0028] (2. Measurement terminal) As shown in FIG. 1, the measurement terminal 100 includes a control unit 10, an image capturing device 2, an input device 3, a display device 4, a communication device 5, a storage device 6, a temperature measuring device 7, a microphone 8, a speaker 9, and the like.

[0029] The control unit 10 controls each unit of the measurement terminal 100 in an integrated manner. The photographing device 2 photographs images. The input device 3 accepts input operations to the measurement terminal 100. The display device 4 displays images photographed by the photographing device 2. The input device 3 may be a touch panel, in which case the input device 3 is configured integrally with the display device 4. The communication device 5 transmits and receives various data between an external communication device and the control unit 10. The memory device 6 stores various data handled by the measurement terminal 100. The temperature measurement device 7 detects the temperature of the person being measured without contact.

[0030] <Control unit of measurement terminal> The control unit 10 includes a registration face photograph transmission processing unit (face registration image transmission processing unit) 11, a measurement processing unit 12, and a display processing unit 13.

[0031] The registration face photo transmission processing unit 11 accepts a registration operation to register the person being measured in the server 200, and transmits a registration face photo (face registration image), which is a photographed face image of the person being measured, to the server 200. The registration face photo transmission processing unit 11 accepts the measurement operator's taking of a face photo of the person being measured on a registration operation acceptance screen D1 (see FIG. 2). If the person being measured is an unregistered person who is not registered in the server 200, the measurement operator performs a face registration operation before the measurement operation.

[0032] The measurement processing unit 12 photographs the person being measured and transmits the facial photograph for authentication to the server 200, and then measures the vital information of the person being measured based on the photographed image of the person being measured and transmits the measurement value to the server 200. The measurement processing unit 12 accepts the measurement worker taking the facial photograph for authentication of the person being measured on the measurement operation screen. The measurement processing unit 12 accepts the measurement worker taking the photograph of the person being measured on the measurement operation screen. The temperature of the person being measured is measured based on the photographed image taken by the temperature measuring device 7.

[0033] The display processing unit 13 controls the display device 4 to display various screens for operation input on the display device 4 and accepts operation input from the measurement operator. During a face registration operation, the display processing unit 13 displays a registration operation acceptance screen D1 that accepts the face registration operation. During a measurement operation, the display processing unit 13 displays a measurement operation screen that accepts the measurement operation. Furthermore, when the display processing unit 13 receives measurement results from the server 200, it displays a measurement result screen. The measurement result screen contains information such as a facial photograph of the person being measured taken during the measurement operation, the person's name, the person's ID, the current measurement value, and a judgment result comparing the current measurement value with past measurement values.

[0034] Furthermore, when the display processing unit 13 receives registration-related information including information about a subject linked to a registration facial photograph from the server 200, it displays a screen according to the received information. In this embodiment, the registration-related information is information including the name of the subject linked to the registration facial photograph. The display processing unit 13 displays a screen indicating that the subject included in the registration-related information has been linked to the registration facial photograph.

[0035] (3. Server) 1, the server 200 includes a control unit 20, a communication device 31, and a storage device 32. The control unit 20 controls each unit of the server 200. The storage device 32 stores various data handled by the server 200. The communication device 31 transmits and receives various data between an external communication device and the control unit 20.

[0036] <Server control section> The control unit 20 includes a registration processing unit 21 , an authentication processing unit 22 , an information management unit 23 , an information acquisition processing unit 24 , and a linking processing unit 25 .

[0037] The registration processing unit 21 registers the registration facial photograph received from the measurement terminal 100 as a facial photograph of the subject in the server 200. The registration processing unit 21 registers (saves) the subject information of the subject received from the input terminal 400 by management console operation using the input terminal 400, in association with the facial photograph of the subject.

[0038] Furthermore, as will be described later, the registration processing unit 21 registers (mainly stores) the subject information linked to the registration facial photograph in association with the registered facial photograph of the subject in association with the registration facial photograph in association with the facial photograph of the subject. That is, the registration processing unit 21 registers the subject information linked to the registration facial photograph in association with the registration facial photograph (facial photograph of the subject) in association with the registration facial photograph in association with the registration facial photograph. Here, the subject is a person registered in the external system 300. The registration processing unit 21 notifies the measurement terminal 100 of the name of the subject linked to the registration facial photograph.

[0039] When the authentication processing unit 22 receives the authentication facial photograph from the measurement terminal 100, it performs facial authentication against the registered facial photograph of the person being measured. If the authentication processing unit 22 can uniquely associate the person being measured in the authentication facial photograph with a registered person, it identifies that person. On the other hand, if a unique association cannot be made, it notifies the measurement terminal 100 that the person is not registered.

[0040] The information management unit 23 manages the measurement values ​​of the vital information of the person being measured received from the measurement terminal 100 in association with the face photograph of the person being measured. The information management unit 23 also compares the measurement values ​​with past measurement values ​​and transmits the measurement results indicating the results of the current measurement operation to the measurement terminal 100.

[0041] The information acquisition processing unit (information acquisition unit) 24 acquires subject information about multiple subjects registered in the external system 300 from the linked external system 300. The subject information includes at least a subject's face photograph (subject's face image), which is a facial image of the subject himself / herself, and the subject's name. The information acquisition processing unit 24 acquires and temporarily stores the subject information about all subjects registered in the external system 300.

[0042] When the linking processing unit 25 receives a registration face photograph from the measurement terminal 100, it at least performs face authentication on the multiple subject face photographs and links the subject information of the subject corresponding to the registration face photograph to the registration face photograph. In other words, the subject corresponding to the registration face photograph is a subject who is determined to be the same person as the person in the registration face photograph as a result of face authentication. The multiple subject face photographs used for face authentication are included in the temporarily stored subject information.

[0043] In this embodiment, the linking processing unit 25 only performs facial authentication, and if the result of the facial authentication determines that the same person as the person being measured is present among multiple subjects, the subject information of the subject determined to be the subject is linked to the registration facial photograph.

[0044] (4. Sequence) Fig. 2 is an example of a sequence diagram in the linking system 1 according to the second embodiment. As shown in Fig. 2, link registration is performed in advance between the server 200 and the external system 300 (S1). The external system 300 transmits the subject information of all subjects (all registrants) registered in the external system 300 to the server 200 (S2). The server 200 temporarily stores the received subject information (S3: processing of the information acquisition processing unit 24). The subject information includes information such as the subject's name, facial photograph (photograph of the subject's face), vital information, date of birth, contact information, etc. This is the preparation stage for linking.

[0045] Next, the measurement operator performs a face registration operation using the measurement terminal 100 (S4). Specifically, the measurement operator displays the registration operation reception screen D1 and takes a facial image of the subject A. The measurement terminal 100 transmits the captured facial photo of the subject A to the server 200 as a facial photo for registration (S5: processing of the registration facial photo transmission processing unit 11).

[0046] The server 200 performs facial authentication of the registration facial photograph received from the measurement terminal 100 against the subject facial photograph in the temporarily stored subject information, and determines which has the highest degree of match in facial authentication (S6). The server 200 links the subject information containing the subject photograph with the highest degree of match with the registration facial photograph of subject A received this time, replaces the subject facial photograph in the subject information with the registration facial photograph, and stores the information (S7: processing of the linking processing unit 25 and registration processing unit 21).

[0047] As a result, the registration facial photograph is registered in server 200 as the facial photograph of subject A, and the subject information is registered as subject information.

[0048] When the server 200 registers the subject A, it transmits the result (registration related information) with the name of the linked subject, "A", to the measurement terminal 100 (S8: processing of the registration processing unit 21).

[0049] When the measurement terminal 100 receives the result with the name attached, it displays a registration result screen D2 indicating that "Mr. A" has been registered (S9: processing of the display processing unit 13).

[0050] As a result, if subject A is registered in the external system 300, the subject's facial photo and subject information can be registered in the server 200 simply by performing the face registration process, eliminating the need for management console operations from the input terminal 400.

[0051] After the registration of the person to be measured in the server 200 is completed, the name, date of birth, etc. of the person to be searched for is transmitted from the external system 300 to the server 200 (S10). The server 200 transmits the ID, etc. of the person to be measured corresponding to the received name, date of birth, etc. to the external system 300 (S11).

[0052] Thereafter, by inputting the ID of the person being measured from the external system 300, the vital information and the like of the person being measured stored in the server 200 can be acquired.

[0053] (5. Description of effects) In the above configuration, if the person being measured is registered in the external system 300, the subject information can be linked to the person being measured simply by performing a face registration operation on the measurement terminal 100. This eliminates the need to input information that has already been registered in the external system 300 when linking with the external system 300, simplifying the registration process.

[0054] In this embodiment, the server 200 associates the subject with the server 200 only through facial recognition, so the measurement operator only needs to register the face, which is extremely easy. Furthermore, the measurement terminal 100 displays the results including the names of the associated subjects, so the associated subjects can be clearly identified.

[0055] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0056] 3 is a block diagram showing an example of the configuration of a linking system 1A including a server 200A and a measurement terminal 100A according to embodiment 2. As shown in FIG. 3, the linking system 1A according to embodiment 2 includes a server 200A instead of the server 200, and a measurement terminal 100A instead of the measurement terminal 100.

[0057] In the linking system 1 according to the first embodiment, the server 200 is configured to link the subject information registered in the external system 300 with the registration face photograph (face photograph of the person being measured) using only face authentication.

[0058] In contrast, in the linking system 1A according to the second embodiment, the server 200A has the measurement operator confirm whether the subject information registered in the external system 300 is appropriate before linking the subject information with the registration face photograph (face photograph of the person being measured) based on the results of the facial authentication, and performs the linking if it is appropriate.

[0059] 3, the server 200A includes a linking processing unit 25A instead of the linking processing unit 25. When the linking processing unit 25A determines, as a result of face authentication, that the same person as the subject is present among multiple subjects, it transmits the name of the subject determined to be the same person to the measurement terminal 100, and prompts the measurement operator to confirm whether the subject is the person indicated by the name. When the linking processing unit 25A receives a confirmation result from the measurement terminal 100 that the name is correct, it links the subject information of the subject determined to be the same person to the registration facial photograph.

[0060] The measurement terminal 100A is equipped with a display processing unit 13A instead of the display processing unit 13. The measurement terminal 100A receives information including the subject's name to be linked to the registration facial photograph as registration-related information from the server 200A. The display processing unit 13A displays a confirmation screen for prompting the user to confirm whether the person with the received name is the person being measured. The measurement terminal 100A further includes a confirmation result transmission processing unit 14 that transmits the confirmation result received on the confirmation screen to the server 200A.

[0061] (sequence) Fig. 4 is an example of a sequence diagram in the linking system 1A according to embodiment 2. The processes of S1 to S6, S7, S10, and S11 in Fig. 4 are the same as the processes of S1 to S6, S7, S10, and S11 in Fig. 2. The difference is that the processes of S21 to S24 are performed between S6 and S7 instead of S8 and S9 in Fig. 2.

[0062] As shown in FIG. 4, when the server 200A determines in S6 that the facial recognition matches highly (the same person), it transmits the name of the subject information with the high match (the name of the subject determined to be the same person) to the measurement terminal 100A for confirmation by the measurement operator (S21).

[0063] When the measurement terminal 100A receives a result including the name "A" of the subject information with a high degree of match, it displays a confirmation screen D3 with the content "Is this Mr. A?" (S22: processing of the display processing unit 13A).

[0064] The measurement operator operates the confirmation screen D3 to input the confirmation result by YES, NO, etc. (S23), and the measurement terminal 100A transmits the confirmation result to the server 200A (S24: processing of the confirmation result transmission processing unit 14). When the server 200A receives a confirmation result (YES) from the measurement terminal 100A that indicates the result is correct, it executes S7.

[0065] (Description of effects) According to the above configuration, the measurement operator is required to confirm suitability before linking the subject information, which means that the work of the measurement company increases by one step compared to embodiment 1, but the accuracy of linking can be improved.

[0066] Here, the name of the subject information with a high degree of match in face authentication is notified to the measurement terminal 100A and confirmed by the measurement operator, but this is not limited to this. For example, if the face authentication result shows that there are multiple candidates, or if there is only one candidate but the degree of match is lower than a predetermined value, the name may be notified to the measurement terminal 100A and confirmed by the measurement operator. This will be described in embodiment 3.

[0067] [Embodiment 3] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0068] In this embodiment, a configuration that can be applied in combination with embodiments 1 and 2 will be described, in which, when the face authentication result indicates that there are multiple candidates, or when it is estimated that the candidates are the same person but the degree of match is lower than a predetermined value, the names are notified to the measurement terminal 100A and the measurement operator confirms them. For convenience of explanation, the configuration applied to the linking system 1A according to embodiment 2 will be described.

[0069] If the facial authentication results indicate that multiple subjects may be the same person as the subject, or if the subject may be the same person as the subject but the degree of match in the facial authentication results is lower than a predetermined value, the linking processing unit 25A in the server 200A identifies the subject as a candidate. The linking processing unit 25A sends the candidate's name to the measurement terminal 100A and prompts the measurement operator to confirm which candidate the subject is. When the linking processing unit 25A receives a confirmation result from the measurement terminal 100A specifying the correct candidate, it links the subject information of the correct candidate to the registration facial photograph.

[0070] The measurement terminal 100A receives, as registration-related information, information including the name of the candidate to be linked to the registration facial photograph. The display processing unit 13A displays a confirmation screen for confirming whether the person being measured is a candidate. The confirmation result transmission processing unit 14 transmits the confirmation result received on the confirmation screen to the server 200A.

[0071] (sequence) Fig. 5 is an example of a sequence diagram in the linking system 1A according to embodiment 3. The processes of S1 to S6, S7, S10, and S11 in Fig. 5 are the same as the processes of S1 to S6, S7, S10, and S11 in Fig. 4. The difference is that the processes of S25 to S28 are performed between S6 and S7 instead of S21 to S24 in Fig. 4.

[0072] As shown in Fig. 5, in S6, server 200A determines whether the facial recognition matches closely (the same person). If there are multiple subjects who may be the same person as the person being measured, or if there is a possibility that the subject may be the same person as the person being measured but the facial recognition result matches less than a predetermined value, the subject is identified as a candidate. Server 200A then transmits the name of the candidate to measurement terminal 100A, prompting the measurement operator to confirm the subject (S25).

[0073] When the measurement terminal 100A receives the result including the candidate's name, it displays a confirmation screen D3 with the content "Is it Mr. A?" or "Is it Mr. A or Mr. B?" (S26: processing of the display processing unit 13A).

[0074] The measurement operator operates the confirmation screen D3 to input the confirmation result, such as "This is Mr. A" (S27), and the measurement terminal 100A transmits the confirmation result to the server 200A (S28: processing of the confirmation result transmission processing unit 14). When the server 200A receives the confirmation result specifying the correct candidate from the measurement terminal 100A, it determines the person to be linked and executes S7.

[0075] (Description of effects) According to the above configuration, even if the authentication result indicates that there are multiple subjects who may be the same person as the person being measured, or even if there is a possibility that the subject may be the same person as the person being measured but the degree of match in the facial recognition results is lower than a predetermined value, the subjects can be linked accurately by having the measurement operator confirm.

[0076] [Embodiment 4] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0077] In this embodiment, a configuration will be described that can be applied in combination with embodiments 1 and 2, in which if the face authentication result indicates that there are multiple candidates, or if there is only one candidate but the degree of match is lower than a predetermined value, additional information is requested from the measurement terminal 100A to determine the person to be linked. For convenience of explanation, the configuration applied to the linking system 1A according to embodiment 2 will be described.

[0078] If the facial authentication result indicates that there are multiple subjects who may be the same person as the subject, or if there is a possibility that the subject may be the same person as the subject but the degree of match in the facial authentication results is lower than a predetermined value, the linking processing unit 25A in the server 200A determines the subject as a candidate. The linking processing unit 25A requests the measurement terminal 100A to input additional information about the subject. When the linking processing unit 25A receives the additional information from the measurement terminal 100A, it determines the candidate to link to the registration facial photograph based on the additional information and links the subject information.

[0079] The measurement terminal 100A receives, as the registration-related information, information requesting additional information about the subject. The display processing unit 13A further includes an additional information transmission processing unit 15 (see FIG. 3) that displays an input screen D4 for inputting the additional information and transmits the additional information input on the input screen D4 to the server 200A.

[0080] (sequence) Fig. 6 is an example of a sequence diagram in the linking system 1A according to embodiment 4. The processes of S1 to S6, S7, S10, and S11 in Fig. 6 are the same as the processes of S1 to S6, S7, S10, and S11 in Fig. 4. The difference is that the processes of S29 to S32 are performed between S6 and S7 instead of S21 to S24 in Fig. 4.

[0081] As shown in Fig. 6, the server 200A determines in S6 those with a high degree of match in face authentication (the same person). At this time, if there are multiple subjects who may be the same person as the person being measured, or if there is a possibility that they are the same person as the person being measured but the degree of match in the face authentication results is lower than a predetermined value, they are considered candidates. The server 200A requests the measurement terminal 100A to input additional information about the person being measured (S29). In the example of Fig. 6, the additional information requested is the date of birth.

[0082] When the measurement terminal 100A receives the request to input the date of birth, it displays an input screen D4 prompting the subject to input the date of birth (S30: processing of the display processing unit 13A).

[0083] The measurement operator operates the input screen D4 to input the birth date of the person being measured (S31), and the measurement terminal 100A transmits the birth date of the person being measured, which is additional information, to the server 200A (S32: processing of the additional information transmission processing unit 15). Upon receiving the additional information from the measurement terminal 100A, the server 200A determines the person to be linked based on the additional information and executes S7.

[0084] (Description of effects) According to the above configuration, if the authentication result indicates that there are multiple subjects who may be the same person as the person being measured, or if there is a possibility that the subject may be the same person as the person being measured but the degree of match in the facial authentication results is lower than a predetermined value, additional information is obtained from the measurement operator. This allows the subject who is the same person as the person being measured to be identified using the additional information, enabling accurate linking. The additional information is not limited to date of birth.

[0085] [Embodiment 5] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0086] The configuration of a linking system 1α according to a fifth embodiment, including a server 200α and a measurement terminal 100, will be described with reference to Fig. 1. Fig. 1 is also a block diagram showing an example of the configuration of the linking system 1α according to the fifth embodiment, including the server 200α and the measurement terminal 100. As shown in Fig. 1, the linking system 1α according to the fifth embodiment includes a server 200α instead of the server 200. The server 200α includes a registration processing unit 21α instead of the registration processing unit 21, and a linking processing unit 25α instead of the linking processing unit 25.

[0087] In the linking system 1 according to embodiment 1, when a registration facial photograph is received from the measurement terminal 100, the server 200 performs facial authentication with the subject's facial photograph contained in the subject information acquired from the external system 300, and links the subject information.

[0088] In contrast, in the linking system 1α of embodiment 5, when an authentication facial photograph is received from the measurement terminal 100, the server 200α performs facial authentication with the subject facial photograph included in the subject information acquired from the external system 300, and links the subject information.

[0089] Specifically, when the linking processing unit 25α in the server 200α receives an authentication facial photograph (a facial image of the person being measured) from the measurement terminal 100, it at least performs facial authentication with multiple subject facial photographs and links the subject information of the subject corresponding to the authentication facial photograph to the authentication facial photograph.

[0090] The registration processing unit 21α registers the authentication facial photograph received from the measurement terminal 100 as the facial photograph of the person being measured in the server 200. The registration processing unit 21α registers (mainly saves) the subject information linked to the authentication facial photograph of the person being measured in association with the authentication facial photograph of the person being measured in the linking processing unit 25α.

[0091] When the display processing unit 13 in the measurement terminal 100 receives from the server 200α measurement results based on the measurement values, including the name of the subject linked to the face authentication image, it displays a screen according to the received information.

[0092] (sequence) Fig. 7 is an example of a sequence diagram in the linking system 1α according to embodiment 5. The processes of S1 to S3, S6, S7, S10, and S11 in Fig. 7 are the same as the processes of S1 to S3, S6, S7, S10, and S11 in Fig. 2. The difference is that the processes of S50 to S51 are performed instead of S4 and S5, and after S7, the processes of S53 to S55 are performed instead of S8 and S9 in Fig. 2.

[0093] As shown in Fig. 7, the measurement operator performs a measurement operation using the measurement terminal 100 without performing a face registration operation (S50). That is, the measurement operator displays the measurement operation screen D5 and takes a photograph of the face of person A. The measurement terminal 100 transmits the facial photograph of person A taken on the measurement operation screen D5 to server 200α as a facial photograph for authentication (S51: processing of measurement processing unit 12). After transmitting the facial photograph for authentication, the measurement terminal 100 measures the vital information of the person A based on the captured image of the person A and transmits the measurement values ​​to server 200α (S51: processing of measurement processing unit 12).

[0094] The server 200α performs facial authentication between the authentication facial photograph received from the measurement terminal 100 and the subject facial photograph in the temporarily stored subject information, and determines which has the highest degree of match (S6). The server 200α links the subject information containing the subject photograph with the highest degree of match with the authentication facial photograph of subject A received this time, replaces the subject facial photograph in the subject information with the authentication facial photograph, and stores the information (S7: processing by the linking processing unit 25α and the registration processing unit 21α).

[0095] The server 200α records the measurement value this time in association with the authentication facial photograph of the subject A (S53: processing of the information management unit 23), and transmits the named measurement result including the name of the linked subject to the measurement terminal 100 (S54).

[0096] When the measurement terminal 100 receives the named measurement result including the name of the linked subject, it displays the measurement result screen D6 including the subject's name (S55: processing of the display processing unit 13).

[0097] (Description of effects) According to the above configuration, the face photo for identification is used in the measurement operation to perform the linking, and the face photo for authentication is used instead of the face photo for registration to register the face photo of the person being measured. This makes it possible to eliminate the need for face registration operations if the person being measured is a person registered in the external system 300.

[0098] [Embodiment 6] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0099] The configuration of a linking system 1β including a server 200β and a measuring terminal 100β according to embodiment 6 will be described with reference to Fig. 3. Fig. 3 is a block diagram showing an example of the configuration of a linking system 1β including a server 200β and a measuring terminal 100β according to embodiment 6. As shown in Fig. 3, the linking system 1β according to embodiment 6 includes a server 200β instead of the server 200A, and a measuring terminal 100β instead of the measuring terminal 100A.

[0100] The server 200β includes a registration processing unit 21β instead of the registration processing unit 21, and a linking processing unit 25β instead of the linking processing unit 25A. The measurement terminal 100β includes a display processing unit 13β instead of the display processing unit 13A.

[0101] In the linking system 1β of embodiment 6, similar to the server 200A described above, the server 200β asks the measurement operator to confirm suitability before linking the subject information registered in the external system 300 with the authentication face photograph as a result of face authentication.

[0102] Specifically, when the linking processing unit 25β in the server 200β determines, as a result of face authentication, that the same person as the person being measured is present among multiple subjects, it transmits the name of the subject determined to be the same person to the measurement terminal 100β, and has the measurement operator confirm whether the subject is the person whose name matches. When the linking processing unit 25β receives a confirmation result that the name is correct from the measurement terminal 100β, it links the subject information of the subject determined to be the same person to the authentication facial photograph.

[0103] Furthermore, if the facial authentication results indicate that there are multiple subjects who may be the same person as the subject, or if there is a possibility that the subject may be the same person as the subject but the degree of match in the facial authentication results is lower than a predetermined value, the linking processing unit 25β in the server 200β identifies the subject as a candidate. The linking processing unit 25β transmits the name of the candidate to the measurement terminal 100β to prompt the measurement operator to confirm which candidate the subject is. When the linking processing unit 25β receives a confirmation result from the measurement terminal 100β specifying the correct candidate, it links the subject information of the correct candidate to the facial photograph for authentication.

[0104] When the display processing unit 13β in the measurement terminal 100β receives from the server 200β information including the name of the subject to be linked to the authentication facial photograph, the display processing unit 13β displays a confirmation screen D3 for confirming whether the subject is the person with the said name. The confirmation result transmission processing unit 14 in the measurement terminal 100β transmits the confirmation result received on the confirmation screen to the server 200β.

[0105] Furthermore, when the display processing unit 13β receives information including the names of multiple candidates to be linked to the authentication facial photograph from the server 200β, it displays a confirmation screen D3 that prompts the subject to confirm which of the multiple candidates the subject is. The confirmation result transmission processing unit 14 in the measurement terminal 100β transmits the confirmation result received on the confirmation screen D3 to the server 200β.

[0106] (sequence) Fig. 8 is an example of a sequence diagram in the linking system 1β according to embodiment 6. The processes of S1 to S3, S6, S7, S10, S11, and S50 to S55 in Fig. 8 are the same as S1 to S3, S6, S7, S10, S11, and S50 to S55 in Fig. 7. The difference is that the processes of S21 to S24 shown in Fig. 4 are performed between S6 and S7.

[0107] Fig. 9 is an example of a sequence diagram in the linking system 1β according to embodiment 6. The processes of S1 to S3, S6, S7, S10, S11, and S50 to S55 in Fig. 9 are the same as S1 to S3, S6, S7, S10, S11, and S50 to S55 in Fig. 7. The difference is that the processes of S25 to S28 shown in Fig. 5 are performed between S6 and S7.

[0108] (Description of effects) In the above configuration, similar to the fifth embodiment, if the person being measured is a person registered in the external system 300, the face registration operation can be eliminated. Moreover, since the measurement operator is required to confirm suitability before linking the subject information, the accuracy of the linking can be improved. Even if the face authentication result indicates that there are multiple subjects who may be the same person as the person being measured, or even if there is a possibility that the person may be the same person as the person being measured but the degree of match in face authentication is lower than a predetermined value, the linking can be performed with high accuracy by having the measurement operator confirm.

[0109] [Embodiment 7] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0110] The configuration of a linking system 1γ including a server 200γ and a measuring terminal 100γ according to embodiment 7 will be described with reference to Fig. 1 and Fig. 3. Fig. 1 and Fig. 3 are block diagrams showing an example of the configuration of a linking system 1γ including a server 200γ and a measuring terminal 100γ according to embodiment 7. As shown in Fig. 1 and Fig. 3, the linking system 1γ according to embodiment 7 includes a server 200γ instead of the server 200 or 200A, a measuring terminal 100α instead of the measuring terminal 100, and a measuring terminal 100γ instead of the measuring terminal 100A.

[0111] 1 and 3, the server 200γ includes a registration processing unit 21γ instead of the registration processing unit 21, and a matching processing unit 25γ instead of the matching processing units 25, 25A. The measuring terminal 100α shown in FIG. 1 includes an available information transmission processing unit 16. The available information transmission processing unit 16 transmits available information used by the measuring terminal 100α for narrowing down to the server 200γ. The measuring terminal 100γ shown in FIG. 3 includes a display processing unit 13γ instead of the display processing unit 13A.

[0112] In the linking system 1γ according to the seventh embodiment, the server 200γ compares the measured values ​​of vital information to narrow down the candidates when the facial recognition results indicate that there are multiple candidates, or when the candidates are presumed to be the same person but the degree of match is lower than a predetermined value. If the server 200γ is unable to uniquely identify the candidate even after narrowing down the candidates, the server 200γ may display a confirmation screen D3 on the measurement terminal 100γ to prompt the measurement operator to confirm, as in the sixth embodiment described above. Alternatively, the server 200γ may acquire available information from the measurement terminal 100α and use the available information to further narrow down the candidates.

[0113] Specifically, when the facial authentication result indicates that there are multiple subjects who may be the same person as the subject, the linking processing unit 25γ in the server 200γ narrows down the candidates by comparing the measurement values ​​of the subject transmitted from the measurement terminal with the vital information of the multiple subjects who may be the same person. If there is a uniquely determined subject, the linking processing unit 25γ links the subject information of the uniquely determined subject to the facial authentication image. On the other hand, if there is no uniquely determined subject, the linking processing unit 25γ considers each of the subjects who may be the same person as a candidate.

[0114] The names of multiple candidates are then transmitted to the measurement terminal 100γ, and the measurement operator is asked to confirm which of the candidates the person being measured is. When the linking processing unit 25γ receives a confirmation result from the measurement terminal 100γ specifying the correct candidate, it links the subject information of the correct candidate to the authentication facial photograph.

[0115] Alternatively, further narrowing down of the candidates is performed using obtainable information about the subject that can be obtained from the measurement terminal 100α and the subject information of each candidate. If there is a uniquely determined subject, the linking processing unit 25γ links the subject information of the uniquely determined subject to the face authentication image.

[0116] The obtainable information may include, for example, location information of the measurement terminal, and the linking processing unit 25γ may further narrow down the search using the location information of the measurement terminal 100α and the address information.

[0117] Furthermore, if the subject information includes information about the time period during which the subject uses the facility equipped with the external system 300, the obtainable information may include information about the measurement time period during which the subject was measured. In this case, the linking processing unit 25γ further narrows down the search using the information about the measurement time period and the information about the time period during which the subject uses the facility.

[0118] In addition, the obtainable information includes an estimated age estimated from a photographed image of the person being measured, and the linking processing unit 25γ may further narrow down the search using the estimated age information and the date of birth of the subject information.

[0119] (sequence) FIG. 10 is an example of a sequence diagram of the linking system 1γ according to the seventh embodiment. The processes of S1 to S3, S6, S7, S10, S11, and S50 to S55 in FIG. 10 are the same as those of S1 to S3, S6, S7, S10, S11, and S50 to S55 in FIG. 7. The difference is that the process of S60 is performed between S6 and S7. In S60, the measurement value of the subject received in S52 is compared with the vital information of a subject who may be the subject. If the comparison results in a uniquely determined subject, the server 200γ links the subject information of the uniquely determined subject to the facial photograph for authentication and registers it.

[0120] Fig. 11 is an example of a sequence diagram in the linking system 1γ according to the seventh embodiment. The processes of S1 to S3, S6, S7, S10, S11, and S50 to S55 in Fig. 11 are the same as S1 to S3, S6, S7, S10, S11, and S50 to S55 in Fig. 10. The difference is that the processes of S25 to S28 shown in Fig. 5 are performed between S60 and S7. As shown in Fig. 11, if the comparison in S60 does not allow the target person to be uniquely narrowed down, the processes of S25 to S28 can be performed to narrow down the target person.

[0121] FIG. 12 is an example of a sequence diagram in the linking system 1γ according to the seventh embodiment. The processes of S1 to S3, S6, S7, S10, S11, and S50 to S55 in FIG. 12 are the same as those of S1 to S3, S6, S7, S10, S11, and S50 to S55 in FIG. 10. The difference is that between S60 and S7, a process of acquiring obtainable information (S61) and a location comparison (S62) are performed. In the example shown in FIG. 12, the location information of the measuring terminal 100α is used as the obtainable information. As shown in FIG. 12, if the comparison in S60 does not allow a unique narrowing down of the target person, the target person can be narrowed down by comparing the location information of the measuring terminal 100α acquired in S61 with the location information included in the target person information.

[0122] (Description of effects) If a unique determination cannot be made using face recognition, the measurement values ​​are used to narrow down the possibilities, thereby improving the accuracy of the linking. Also, if a unique determination cannot be made even after narrowing down the measurement values, the measurement operator is asked to confirm, which minimizes the need for the measurement operator. A configuration in which the possible information is used to narrow down the possibilities improves the accuracy of the linking without causing the measurement operator any trouble.

[0123] [Software implementation example] The functions of the measurement terminals 100, 100A, 100α, 100β, 100γ and servers 200, 200A, 200α, 200β, 200γ (hereinafter referred to as "devices") can be realized by a program that causes a computer to function as the device, and a program that causes a computer to function as each control unit of the device.

[0124] In this case, the device includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The control device and storage device execute the program, thereby realizing the functions described in each of the above embodiments.

[0125] The program may be non-transitory and may be recorded on one or more computer-readable recording media. The recording media may or may not be included in the device. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0126] Furthermore, some or all of the functions of the control blocks can be realized by logic circuits. For example, an integrated circuit in which a logic circuit that functions as each of the control blocks is formed is also included in the scope of the present invention. In addition, the functions of the control blocks can also be realized by, for example, a quantum computer.

[0127] Furthermore, each process described in each of the above embodiments may be executed by AI (Artificial Intelligence). In this case, the AI ​​may run on the control device or on another device (for example, an edge computer or a cloud server).
