The present invention relates to a display device.

In recent years, there has been increasing interest in preventing the spread of infectious diseases. For infectious diseases accompanied by fever such as pneumonia caused by the new coronavirus, a person suspected of being infected can be easily extracted by measuring the temperature. Therefore, in facilities such as office buildings, hospitals, and commercial facilities, the facility manager measures the temperature of the facility users near the entrance of the facility, isolates the users suspected of having fever from other users, and goes to the facility. Admission is restricted. However, since the administrator is in close proximity to or in contact with many users during temperature measurement, there is a problem that both the administrator and the user may be infected.

Patent Document 1 measures the body temperature of a user of a facility using a temperature camera, and indicates that fever is suspected when the measured body temperature exceeds a preset maximum body temperature, and the body temperature is the maximum body temperature. A body temperature measuring device that allows admission to the facility if it does not exceed the above is described. By using the body temperature measuring device described in Patent Document 1, the administrator can measure the temperature of the user without approaching or contacting the user, and can identify the user suspected of having fever.

FIG. 4 is a diagram showing an example of the first guidance screen 400 displayed on the first display unit 21. The first guidance screen 400 is displayed to indicate the direction D2 for the user to enter the facility as the direction in which the user should proceed when the body temperature of the user is determined to be normal. In the example shown in FIG. 1, since the direction D2 for entering the facility is the right direction when viewed from the user, the first guidance screen 400 is the character C whose movement is controlled so as to indicate the right direction when viewed from the user. including. If the direction of entry is clear (for example, if the user knows how to enter in an office or if an entrance gate is installed near the display device), character C May indicate the direction in which the user is heading by using a voice output that prompts the user to enter, such as "Welcome, please proceed" without giving a specific direction.

FIG. 5 is a diagram showing an example of the second guidance screen 500 displayed on the first display unit 21. The second guidance screen 500 is displayed to indicate the direction D3 to the inspection area as the direction in which the user should proceed when it is determined that the body temperature of the user is not normal. In the example shown in FIG. 1, since the direction D3 to the inspection area is the left direction when viewed from the user, the second guidance screen 500 is the character C whose movement is controlled so as to indicate the left direction when viewed from the user. including.

The operation of the character C on the second guidance screen 500 is controlled to be smaller than the operation of the character C on the first guidance screen 400. The fact that the movement of the character C is small means that there are few parts of the character C that operate, or that the area corresponding to the movement range of the character C on the screen is small. In the examples shown in FIGS. 4 and 5, the forearm portion and the upper arm portion of the character C are operating on the first guidance screen 400, whereas only the forearm portion of the character C is operating on the second guidance screen 500. ing. That is, the portion of the character C operating on the second guidance screen 500 is controlled to be smaller than the portion of the character C operating on the first guidance screen 400.

FIG. 6 is a diagram showing an example of the body temperature display screen 600 displayed on the second display unit 25. The body temperature display screen 600 includes a captured image 601, a person detection object 602, and a body temperature display object 603.

The captured image 601 is an image of the user captured by the imaging unit 23. The person detection object 602 is an object indicating an area corresponding to the user in the captured image 601. In the example shown in FIG. 6, the person detection object 602 shows a region including the face of the user, but may indicate a region including the whole body of the user, or may indicate another portion. The body temperature display object 603 is an object indicating the body temperature of the user indicated by the person detection object 602, which is displayed in the vicinity of the person detection object 602, respectively. As the captured image 601, the user's image captured by the thermal image capturing unit 24 may be used.

FIG. 7 is a diagram showing an example of the data structure of the operation table 271 stored in the storage unit 27. The operation table 271 stores the determination result, the guidance direction, the operation, the voice, the volume, and the like in association with each other.

The determination result is information indicating the result of determining whether or not the body temperature of the user is normal. The guidance direction is the direction in which the user should proceed according to the result of the determination. In the example shown in FIG. 7, since the direction D2 for entering the facility is the right direction when viewed from the user, the “right direction” guidance direction is associated with the determination result of “normal body temperature”. Further, since the direction D3 to the examination area is the left direction when viewed from the user, the "left direction" guidance direction is associated with the determination result of "the body temperature is not normal".

The motion is information indicating the motion of the character C for indicating the direction in which the user should proceed. When the character C is controlled to perform a "large guidance operation to the right", the first guidance screen 400 is displayed. Further, when the character C is controlled to perform a "small guidance operation to the left", the second guidance screen 500 is displayed. As the operation, a moving image file or the like may be stored, or data or the like indicating the movement of the joints of the character may be stored. The voice is information indicating the voice as the utterance of the character for indicating the direction to be advanced to the user. As the voice, for example, a voice file or the like is stored.

The volume is information indicating the volume when the associated voice is output. In the example shown in FIG. 7, the determination result of "body temperature is normal" is associated with the volume of "loud", and the determination result of "body temperature is not normal" is associated with the volume of "low". That is, the volume of the utterance when the body temperature is determined to be normal is controlled to be lower than the volume of the utterance when the body temperature is determined to be normal. In the case of a "low" volume, the user who is the target of the utterance may miss the sound, so the display output on the second display unit 25 may be displayed with caution (for example, displayed in red).

Each data of the operation table 271 is preset according to the structure of the facility and stored in the storage unit 27.

FIG. 8 is a diagram showing an example of the data structure of the person table 272 stored in the storage unit 27. The person table 272 stores the person ID, the person area, the body temperature, the determination result, the position, the traveling direction, and the like in association with each other.

The person ID is identification information for identifying a user detected in the captured image captured by the imaging unit 23. The person area is information that identifies the person area detected in the captured image, and is, for example, information that indicates the center position of the person area. The information for identifying the person area may include information indicating the size and shape of the area. The body temperature is information indicating the detected body temperature of the user. The determination result is information indicating the result of determining whether or not the body temperature of the user is normal. The position is information indicating the position of the user's feet. The traveling direction is information indicating the traveling direction of the user.

Each data of the person table 272 is generated by the display device 2 in the first storage process described later, and is stored in the storage unit 27.

The display device 2 asynchronously executes the first storage process, which will be described later, normal control and emergency control in parallel. These processes are repeatedly executed periodically or irregularly while the processing unit 28 controls the display of the character C imitating a guard on the first display unit 21. These processes are realized by the processing unit 28 collaborating with each component of the display device 2 based on the program stored in the storage unit 27.

First, the display control of the character C will be described. The processing unit 28 controls the display of the character C by executing the program. The processing unit 28 detects the user, as will be described later in the description of the first storage process. In a situation where the user is not detected, the processing unit 28 causes the character C to perform an eye-catching operation for moving the line-of-sight direction and the body direction of the character C within a predetermined range (for example, 45 degrees with respect to the front). When the image display is controlled and the user is detected outside the reception area A2, the image display of the character C is controlled so as to execute the tracking operation toward the user who has detected the line of sight of the character C. As a result, it is possible to display an image that seems to be a security guard who performs real guards, and the presence as a security guard is demonstrated. Further, when the processing unit 28 detects a user or utterances from the user in the reception area A2, the processing unit 28 controls the voice output so that the character C imitating a security guard interacts with the user. By doing so, we will provide reception and guidance to the users of the facility.

Further, the processing unit 28 may determine whether or not the user has an intention to enter the facility, and may control the display of the character C so as to provide guidance according to the temperature measurement result when there is an intention to enter the facility. For example, the processing unit 28 detects the traveling direction of the user, as will be described later. Judgment is made based on whether or not the detected user's direction of travel is the direction of entering the facility, and the intention to enter is determined according to the content of the user's utterance (for example, "I came in a meeting with Mr. XX"). You may judge the presence or absence. When responding to a user who does not intend to enter, that is, when responding according to the result of temperature measurement, a predetermined utterance (for example, greeting) is given to the user detected in the response area A2. do. In addition, when a question from the user (for example, "Where is the toilet?") Is received, voice output or audio output is performed along the dialogue table that links the question content stored in the storage unit 27 in advance with the answer to the question. Guidance is provided by display control (for example, "Please follow the passage on your right to reach the toilet"). In the detection of the utterance content, as will be described later in the explanation of the normal control, the utterance content is detected by applying known voice recognition technology and natural language processing technology to the input voice acquired from the voice input / output unit 26. .. Character C is made to perform a predetermined movement or utterance according to the keyword included in the detected utterance content.

FIG. 9 is a flow chart showing an example of the flow of the first storage process executed by the display device 2.

First, the measuring unit 281 measures the body temperature of one or a plurality of users in the temperature measuring area A1 (S101). The measurement unit 281 acquires an image captured by the image pickup unit 23. The measuring unit 281 inputs the captured image to the trained model trained to output the person area indicating the person in the captured image when the captured image is input, so that the person corresponding to the user in the captured image is input. Detect the area. The trained model is, for example, a neural network for object detection such as R-CNN (Region with Convolutional Neural Network) or SSD (Single Shot Detector).

The measurement unit 281 acquires the thermal image data generated by the thermal image imaging unit 24. The measuring unit 281 identifies a region of thermal image data corresponding to a human region of the detected captured image. The measuring unit 281 acquires the temperature of the area of the specified thermal image data as the body temperature of the user. The measurement unit 281 displays the body temperature display screen 600 on the second display unit 25 based on the acquired captured image, the detected person area, and the acquired body temperature.

The measurement unit 281 identifies the same user as the user indicated by the detected person area from the users stored in the person table 272. For example, the measuring unit 281 calculates the difference between the center position of the detected person area and the center position of the person area stored in the person table 272, and detects a user whose difference is equal to or less than a predetermined value. Identify as the same user as the user indicated by the area. The measurement unit 281 updates the person table 272 by storing the information for specifying the detected person area and the acquired body temperature in the person table 272 in association with the person ID of the specified user. In this way, while tracking the users extracted over the plurality of input images, the user can store the temperature measurement results in advance on the person table 272 for each user to be tracked. Upon entering the reception area A2, it becomes possible to promptly execute guidance according to the result of the temperature measurement of the user.

If the same user as the user indicated by the detected person area is not stored in the person table 272, the measurement unit 281 uses the information for identifying the detected person area and the acquired body temperature as a new person ID. It is stored in the person table 272 in association with.

Subsequently, the determination unit 282 determines whether or not the measured body temperature is normal (S102). When the body temperature stored in the person table 272 is less than a predetermined value, the determination unit 282 determines that the measured body temperature is normal. When the body temperature stored in the person table 272 is equal to or higher than a predetermined value, the determination unit 282 determines that the measured body temperature is not normal. The determination unit 282 stores the determination result in the person table 272 in association with the body temperature.

Subsequently, the detection unit 283 calculates the position and the traveling direction of the user in the temperature measurement area (S103), and ends the detection process. The detection unit 283 identifies an area of distance image data corresponding to the person area stored in the person table 272. The detection unit 283 calculates the position of the user based on the distance information associated with the area of the specified distance image data. The detection unit 283 calculates the traveling direction of the user from the difference between the calculated position of the user and the position stored in the person table 272. The detection unit 283 stores the calculated user position and traveling direction in the person table 272.

FIG. 10 is a flow chart showing an example of a flow of normal control in which a person in a reception area is sequentially treated as a reception target and a response is performed to the person to be treated based on the measurement result.

First, the detection unit 283 determines whether or not a user in the reception area has been detected (S201). The detection unit 283 determines whether or not the user in the reception area is detected by determining whether or not each of the positions stored in the person table 272 is included in the range set in advance as the reception area. do. When the user in the reception area is not detected (S201-No), the process of determining whether or not the user in the reception area is detected is repeated.

When a user in the reception area is detected (S201-Yes), the normal control unit 284 determines whether or not the body temperature of the user in the detected reception area is normal (S202). The normal control unit 284 refers to the determination result of the person table 272 and determines whether or not the detected user's body temperature is normal. Further, the normal control unit 284 can promptly respond even when a plurality of persons are detected by sequentially executing the response from the person closest to the display device 2.

When it is determined that the body temperature of the detected user is normal (S202-Yes), the normal control unit 284 normally enters the facility as the direction in which the user should proceed as a response to the detected user. Character C is controlled so as to indicate D2 (S203). The normal control unit 284 refers to the operation table 271 and acquires the operation, voice, and volume associated with the determination result of “body temperature is normal”. The normal control unit 284 controls the character C so as to perform the acquired operation, and causes the first display unit 21 to display the first guidance screen 400. Further, the normal control unit 284 outputs the acquired voice from the voice output unit 26 at the acquired volume as the utterance of the character C.

Subsequently, the normal control unit 284 determines whether or not the first time has elapsed since the character C was controlled so as to indicate the direction D2 for entering the facility (S204). The first time is a predetermined time that is sufficient for the user who has been indicated the direction to proceed to leave the reception area, for example, 5 seconds. If it is determined that the first time has not elapsed (S204-No), the response process returns to S204. That is, the normal control unit 284 waits until the first time elapses.

When it is determined that the first time has elapsed (S204-Yes), the normal control unit 284 guides another user to the reception area (S205), and ends the normal control for responding to the user. To respond to the next user. The normal control unit 284 guides another user to the reception area by outputting a voice such as "Next person, please." From the voice output unit 26 as the utterance of the character C. That is, the normal control unit 284 usually responds to another user after the lapse of the first time after responding to the detected user. Further, in the normal control, the determination of whether or not the first time has elapsed may be omitted, and the response to the next user may be started immediately after the response to the user is performed. Since there may be a plurality of persons in the reception area, if there are a plurality of persons in the reception area, the process of guiding other users to the reception area (S205) is omitted, and the following are sequentially performed. Normal control for responding to the user is executed.

When it is determined that the body temperature of the user detected in S202 is not normal (S202-No), the normal control unit 284 enters the inspection area as the direction in which the user should proceed as a response to the detected user. The character C is controlled so as to indicate the direction D3 (S206). The normal control unit 284 refers to the operation table 271 and acquires the operation and the voice associated with the determination result of “the body temperature is not normal”. The normal control unit 284 controls the character C so as to perform the acquired operation, and causes the first display unit 21 to display the second guidance screen 500. Further, the normal control unit 284 outputs the acquired voice from the voice output unit 26 at the acquired volume as the utterance of the character C.

Subsequently, the normal control unit 284 determines whether or not the detected traveling direction of the user is the direction D2 for entering the facility (S207). The normal control unit 284 refers to the person table 272 and determines whether or not the traveling direction is the direction D2 for entering the facility.

When the traveling direction is the direction D2 for entering the facility (S207-Yes), the normal control unit 284 outputs a warning (S208). The warning is given by outputting a voice as an utterance of the character C. For example, the normal control unit 284 outputs a warning by repeatedly outputting a voice such as "Please proceed to the left" from the voice output unit 26. The warning may be given by controlling the operation of the character C, or by outputting a sound effect. The case where the traveling direction is the direction D2 for entering the facility is not limited to the case where the traveling direction exactly matches the direction D2, and means that the traveling direction is included in a predetermined angle range including the direction D2. If the traveling direction is not the direction D2 for entering the facility (S207-No), the normal control proceeds to S209.

Subsequently, the normal control unit 284 determines whether or not a second time has elapsed since the character C was controlled so as to indicate the direction D3 to the inspection area (S209). The second time is longer than the first time, which is preset enough for the user indicated in the direction to travel to move to the inspection area, for example, in 10 seconds. be. If it is determined that the second time has not elapsed (S209-No), the response process returns to S207. That is, the normal control unit 284 waits until the second time elapses.

When it is determined that the second time has elapsed (S209-Yes), the normal control unit 284 guides another user to the reception area (S205), and ends the normal control for responding to the user. Then move on to responding to the next user. That is, the normal control unit 284 usually responds to another user after the lapse of a second time after responding to the detected user. Even when the determination of whether or not the first time has elapsed is omitted, it is set in advance so that the user who has been indicated the direction to proceed as described above can move to the inspection area. The time given may be set as the second time.

FIG. 11 is a flow chart showing an example of the flow of emergency control processing.

First, the emergency control unit 285 determines whether or not the body temperature of the user in the temperature measurement area is normal (S301). The emergency control unit 285 determines whether or not the user's body temperature is normal by referring to the determination result of the person table 272. When it is determined that the body temperature of the user in the temperature measurement area is normal (S301-Yes), the process of determining whether or not the body temperature of the user in the temperature measurement area and outside the reception area is normal is repeated.

When it is determined that the body temperature of the user in the temperature measurement area is not normal (S301-No), the emergency control unit 285 interrupts the normal control (S302). The emergency control unit 285 interrupts the normal control by controlling so that the normal control process for the next person is not executed after waiting until the normal control currently being executed for the person currently being handled is completed. do. The emergency control unit 285 may immediately interrupt the normal control currently being executed. In this case, a voice such as "Please wait a moment" is output as the utterance of the character C, and the user in the reception area is put on standby.

Subsequently, the emergency control unit 285 controls the character C so as to indicate the direction D3 to the inspection area as a response to the user whose body temperature is determined to be abnormal (S303). The emergency control unit 285 refers to the operation table 271 and acquires the operation, voice, and volume associated with the determination result of "body temperature is not normal". The emergency control unit 285 controls the character C so as to perform the acquired operation, and causes the first display unit 21 to display the second guidance screen 500.

Further, the emergency control unit 285 refers to the position of the person table 272 and identifies the positional relationship between the user who is determined to have an abnormal body temperature and other users. The positional relationship of other users is, for example, information indicating the order in which the users whose body temperature is determined to be abnormal are lined up when a plurality of users are lined up in the temperature measurement area. The emergency control unit 285 outputs the voice acquired with the specified positional relationship as the utterance of the character C from the voice output unit 26 at the acquired volume. For example, the emergency control unit 285 outputs a voice such as "Third-lined person, proceed to the left and inspect."

Subsequently, the emergency control unit 285 determines whether or not the traveling direction of the user determined to have an abnormal body temperature is the direction D3 toward the examination area (S304). The emergency control unit 285 refers to the traveling direction of the person table 272 and determines whether or not the traveling direction is the direction D3 to the inspection area. If the traveling direction is not the direction D3 to the inspection area (S304-No), the response process returns to S304. That is, the emergency control unit 285 waits until it is determined that the traveling direction of the user whose body temperature is determined to be abnormal is the direction D3 toward the examination area.

When the traveling direction of the user whose body temperature is not normal is the direction D3 to the examination area (S304-Yes), the emergency control unit 285 guides another user to the reception area (S305), and the emergency control ends. .. When there are a plurality of persons in the reception area A2 in S305, the person closest to the display device is sequentially treated.

As described above, the display device 2 measures the body temperature of the user of the facility and indicates the direction in which the user should proceed according to the result of determining whether or not the measured body temperature is normal. The character C is controlled to execute normal control for responding to the user. As a result, the display device 2 can appropriately guide a person suspected of having a fever and reduce the risk of infection.

Further, the display device 2 indicates the direction D2 for entering the facility when the user's body temperature is determined to be normal in the normal control, and is inspected when the user's body temperature is determined to be abnormal. The operation of the character C is controlled so as to indicate the direction D3 to the area. As a result, it can be appropriately induced according to the result of temperature measurement, and the risk of infection can be reduced.

Further, the display device 2 outputs a warning when the direction D3 to the inspection area is indicated as the direction in which the user should proceed and the direction in which the user travels is the direction D2 for entering the facility. do. As a result, the display device 2 can more appropriately induce a person suspected of having a fever and reduce the risk of infection.

Further, when it is determined that the body temperature of the user is normal, the display device 2 responds to another user after the lapse of the first time after responding to the user, and it is determined that the body temperature is not normal. In that case, after responding to the user, the other user is responded to after the lapse of the second time longer than the first time. As a result, the user suspected of having a fever is sufficiently separated from the reception area before other users are guided into the reception area, so that the person suspected of having a fever may be in close proximity to the other user. Is reduced.

Further, the display device 2 controls so that the operation of the character C on the second guidance screen 500 is smaller than the operation of the character C on the first guidance screen 400. That is, in the display device 2, the operation of the character C when it is determined that the body temperature of the user is not normal is smaller than the operation of the character C when it is determined that the body temperature is normal. Control the operation. As a result, when a user is suspected of having a fever, the possibility that the content of the response to the user will be seen by others is reduced, and the privacy of the person suspected of having a fever can be protected.

Further, the display device 2 sets the volume of the utterance so that the volume of the utterance of the character C when the body temperature is determined to be normal is lower than the volume of the utterance when the body temperature is determined to be normal. Control. As a result, when a user is suspected of having a fever, the possibility that the content of the response to the user will be heard by another person is reduced, and the privacy of the person suspected of having a fever can be protected.

Further, the display device 2 interrupts the normal control for responding to the detected user when it is determined that the body temperature of another user different from the detected user in the response area is not normal. Perform emergency control to respond to other users. This makes it possible for the display device 2 to promptly guide a person suspected of having a fever.

Further, in the emergency control, the display device 2 ends the emergency control and executes the normal control when the traveling direction of the responding user is the direction D3 to the inspection area. As a result, after the person suspected of having a fever starts moving according to the guidance in the emergency control, the response to other users is performed, and it becomes possible to reduce the risk of infection among the users.

In the above description, the display device 2 assumes that the first storage process, the normal control, and the emergency control are executed in parallel, but only the first storage process and the normal control are executed in parallel without executing the emergency control. You may do it.

In the above description, the normal control unit 284 determines whether or not the body temperature of the person detected in the normal control S202 is normal, but the present invention is not limited to such an example. The normal control unit 284 may control the character C so as to indicate the direction D2 in which the user enters the facility as the direction in which the user should proceed. That is, since the person suspected of having a fever is treated by emergency control while waiting in the temperature measurement area A1, it is considered that the user who has moved to the reception area A2 is not a person suspected of having a fever. Therefore, by doing so, it is possible to quickly isolate a person suspected of having heat generation from other users of the facility while reducing the processing load of the display device 2.

In the above description, the control unit 284 normally provides guidance according to whether or not the body temperature of the detected person is normal, but in addition to this, the user wears a mask from the captured image. If it is determined that the mask is not worn, the voice output or display control may be performed to encourage the mask to be worn, or the admission may be refused. Similarly, the emergency control unit 285 may also respond according to the result of determining whether or not the mask is worn.

In the above description, the first time and the second time are assumed to be preset times, but the present invention is not limited to such an example. For example, the display device 2 may determine that the first time has elapsed when the direction D2 for entering the facility is detected as the traveling direction of the responding user. Further, the display device 2 may determine that the second time has elapsed when the responding user reaches the inspection area. This prevents users who are not suspected of having a fever from being in close proximity to users who move to the next reception area, and it is possible to more appropriately isolate those who are suspected of having a fever from other users. It becomes.

In the above description, the determination unit 282 determines whether or not the body temperature is normal based on whether or not the body temperature is less than a predetermined value, but the present invention is not limited to such an example. For example, the determination unit 282 may determine whether or not the body temperature is normal by comparing the normal temperature preset for each user with the measured body temperature.

In this case, the storage unit 27 stores the information about the characteristics of the user and the normal heat of the user in advance in association with each other. The user's characteristics are information about the characteristics that can identify the user from the captured image, such as the positional relationship between the eyes and the nose. Then, in S101 of the first storage process, when the measurement unit 281 extracts the person area from the captured image, the measurement unit 281 further extracts the characteristics of the user corresponding to the extracted person area. Further, in S102, the determination unit 282 identifies the normal temperature of the user based on the extracted characteristics of the user, and compares the measured body temperature with the specified normal heat to determine whether or not the body temperature is normal. judge. For example, the determination unit 282 determines that the body temperature is normal when the difference between the measured body temperature and the normal temperature is less than a predetermined value.

This makes it possible to identify users suspected of having a fever with high accuracy in facilities such as office buildings where the number of users is limited in advance. The user's normal fever may be preset by the user, or may be calculated by the measuring unit 281 measuring the user's body temperature over a predetermined period.

(Second embodiment)
FIG. 12 is a diagram showing an example of a schematic configuration of the response system 1a according to the second embodiment. Hereinafter, the same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted as appropriate. The reception system 1a is provided in the vicinity of the entrance 11 of the facility, similarly to the reception system 1.

The response system 1a has a display device 2a arranged on the flow line D1 of the user of the facility who entered from the entrance 11, and a partition 13 arranged on the side of the display device 2a. The response system 1a differs from the response system 1 in that it does not have the rope partition 12.

When the user of the facility enters the facility from the entrance 11, he / she waits in the temperature measurement area A1 according to the flow line D1 and moves to the reception area A2 one by one. The display device 2a measures the body temperature of the user in the temperature measurement area A1 and determines whether or not the body temperature is normal. When the user moves into the reception area A2, the display device 2a indicates the direction D2 for the user to enter the facility or the direction D3 for the inspection area A3 as the direction in which the user should proceed, depending on the result of the determination.

Further, since the rope partition is not provided, there are other users such as moving users in addition to the waiting users in the temperature measurement area A1. When the display device 2 determines that the body temperature of the user in the temperature measurement area A1 is not normal, the display device 2 includes feature information indicating a feature that can uniquely identify the user by utterance from among a plurality of users, and the display device 2 includes the feature information. Outputs instruction information for moving the user to the inspection area A3.

FIG. 13 is a diagram showing an example of a schematic configuration of the display device 2a. The display device 2a differs from the display device 2 in that the storage unit 27 stores the person table 272a as data instead of the person table 272. Further, the display device 2a is different from the display device 2 in that it has the processing unit 28a instead of the processing unit 28.

The processing unit 28a has a configuration that comprehensively controls the operation of the display device 2a, and includes one or a plurality of processors and peripheral circuits thereof. The processing unit 28a controls the operation of each configuration of the display device 2a so that the processing of the display device 2 is appropriately executed based on the program stored in the storage unit 27, and executes the processing.

The processing unit 28a includes a measurement unit 281a, an extraction unit 282a, a determination unit 283a, a detection unit 284a, a normal control unit 285a, a specific unit 286a, and an emergency control unit 287a as functional blocks. Each of these parts is a functional module realized by a program executed by the processing unit 28a. Each of these parts may be mounted on the display device 2a as firmware.

FIG. 14 is a diagram showing an example of the data structure of the person table 272a stored in the storage unit 27. The person table 272a stores the person ID, the person area, the body temperature, the determination result, the position, the traveling direction, the feature information, and the identification feature information in association with each other.

The characteristic information is information indicating the characteristics of a plurality of users, and is information on the clothes, belongings, and the like of the users. The identification feature information is feature information that can uniquely identify one user by utterance from among a plurality of users among the feature information. The feature information and the identification feature information are generated by the display device 2a and stored in the person table 272a in the second response process described later.

The display device 2a asynchronously executes the second storage process described later, the normal control described with reference to FIG. 10, and the instruction information output process described later in parallel. These processes are repeatedly executed periodically or irregularly while the first display unit 21 displays the character C imitating a guard. These processes are realized by the processing unit 28a collaborating with each component of the display device 2a based on the program stored in the storage unit 27.

FIG. 15 is a diagram showing an example of the flow of the second storage process executed by the display device 2a.

First, the measuring unit 281a measures the body temperature of a plurality of users in the temperature measuring area (S401). The measurement unit 281a acquires an image captured by the image pickup unit 23. The measuring unit 281a detects a person area corresponding to the user in the captured image. The measuring unit 281a acquires the temperature of the region corresponding to the detected human region of the thermal image data generated by the thermal image imaging unit 24 as the body temperature of the user. The measuring unit 281 sets a person ID for the detected user, associates it with the acquired body temperature, and stores it in the person table 272.

Subsequently, the extraction unit 282a extracts identification feature information indicating a feature that can uniquely identify one user by utterance from a plurality of users in the temperature measurement area (S402). The extraction unit 282a relates to the user's clothing or belongings by inputting the captured image into a trained model trained to output features relating to the user's clothing or belongings when the captured image is input. Detects feature information that indicates a feature. The characteristic information is indicated by a combination of a preset type of clothing or belongings such as "clothes, black", "bag, plaid", etc., and features relating to the appearance of the clothing or belongings. The extraction unit 282a associates the detected feature information with the user based on the positional relationship with the person area in the captured image, and stores it in the person table 272a. The feature information may be detected at the same time as the detection of the person area of S401.

The extraction unit 282a extracts identification feature information indicating a feature that can uniquely identify one user by utterance from a plurality of users from the stored feature information. In the example shown in FIG. 14, since only the user with the person ID of "0001" has the characteristic information of "clothes, red", the characteristic information of "clothes, red" is used to obtain "0001". The user of the person ID can be uniquely identified. Therefore, the extraction unit 282a extracts the characteristic information of "clothes, red" as the identification characteristic information for the user with the person ID of "0001". Similarly, the extraction unit 282a extracts the feature information of "bag, red" as the identification feature information for the user of the person ID of "0002". As for the user with the person ID of "0003", the identification feature information is not extracted because the uniquely identifiable feature information is not detected. The extraction unit 282a stores the extracted identification feature information in the person table 272a.

Subsequently, the determination unit 283a determines whether or not the measured body temperature is normal (S403). The determination unit 283a stores the determination result in the person table 272a in association with the body temperature.

Subsequently, the detection unit 284a calculates the position and the traveling direction of the user in the temperature measurement area (S404), and ends the second storage process. The detection unit 284a calculates the position and the traveling direction of the user in the same manner as in S103, and stores them in the person table 272a.

FIG. 16 is a flow chart showing an example of the flow of instruction information output processing.

First, the identification unit 286a identifies a user whose body temperature is determined to be abnormal and whose identification feature information has been extracted (S501). The specific unit 286a refers to the determination result of the person table 272a and identifies the user who is determined to have an abnormal body temperature. When the specified user includes a user from which the identification feature information has been extracted, the identification unit 286a identifies the user as a user whose body temperature is determined to be abnormal and the identification feature information has been extracted. If the extracted user does not include the user from which the identification feature information has been extracted, the specific unit 286a does not specify the user (S501-No), and the instruction information output process ends.

When it is determined that the body temperature is not normal and the user from which the identification feature information is extracted is identified (S501-Yes), is the emergency control unit 287a in the direction of leaving the facility in the direction of travel of the identified person? It is determined whether or not (S502). The emergency control unit 287a refers to the person table 272a and determines whether or not the direction of leaving the facility is detected as the traveling direction of the specified person. The direction of leaving the facility is the direction from the user's current position toward the exit 14.

When the traveling direction is not the direction of leaving the facility (S502-No), the emergency control unit 287a interrupts the normal control (S503).

Subsequently, the emergency control unit 287a outputs instruction information including the identification feature information and moving the specified user to the inspection area (S504). For example, when the identification feature information is "bag, red", the emergency control unit 287a outputs a voice such as "If you have a red bag, proceed to the left and move to the inspection area." Output from unit 26.

Subsequently, the emergency control unit 287a determines whether or not the traveling direction of the specified user is the direction D3 to the inspection area (S505). The emergency control unit 287a refers to the person table 272a and determines whether or not the traveling direction is the direction D3 to the inspection area. When the traveling direction is not the direction D3 to the inspection area (S505-No), the instruction information output process returns to S505. That is, the emergency control unit 287a waits until it is determined that the traveling direction of the specified user is the direction D3 to the inspection area.

Subsequently, the emergency control unit 287a guides another user to the reception area (S506). Since there may be a plurality of persons in the reception area, if there are a plurality of persons in the reception area, the process of guiding other users to the reception area (S506) is omitted, and the following are sequentially performed. Move on to processing for users.

In S502, when the traveling direction is the direction of leaving the facility (S502-Yes), the instruction information output process ends. That is, when the traveling direction of the specified user is the direction of leaving the facility, the emergency control unit 287a does not output the instruction information.

As described above, the display device 2a measures the body temperature of the user of the facility and extracts feature information indicating a feature that can uniquely identify one user by utterance from a plurality of users. Further, the display device 2a outputs instruction information including the identification feature information and moving the identified person to the inspection area when it is determined that the body temperature is not normal and the person from which the identification feature information is extracted is identified. do. As a result, the display device 2a makes it possible to appropriately guide a person suspected of having a fever and reduce the risk of infection.

That is, if other users such as moving users are included in addition to the users waiting in the temperature measurement area, even if other users suspect fever, it is appropriate for those users. It is difficult to convey the instruction information to. By including the identification feature information in the instruction information, the display device 2a makes it easy for the user suspected of having a fever to recognize that the output instruction information is for himself / herself, and appropriately guides the person suspected of having a fever. It makes it possible to reduce the risk of infection.

Further, the display device 2a executes a normal control for responding to a person in the reception area, and interrupts the normal control when it is determined that the body temperature is not normal and the person from which the identification feature information is extracted is identified. And output the instruction information. As a result, the display device 2a makes it possible to appropriately guide a person suspected of having a fever and reduce the risk of infection while guiding the user who is not suspected of having a fever.

Further, the display device 2a does not output instruction information to the specified user when the traveling direction of the specified user is the direction of leaving the facility. As a result, the display device 2a does not urge the user who is about to leave the facility to perform unnecessary inspections.

In the above description, in S501, the specific unit 286a identifies the user whose body temperature is determined to be abnormal and the identification characteristic information is extracted, but the present invention is not limited to such an example. In S501, the specific unit 286a may specify only the users outside the reception area among the users whose body temperature is determined to be abnormal and the identification feature information is extracted. As a result, the display device 2a can promptly guide a person who is suspected of having a fever outside the reception area, and can reduce the risk of infection.

In the above description, the identification feature information is information about the user's clothes or belongings, but the present invention is not limited to such an example. The identification feature information may include information about the clothes or belongings of another user and information indicating a relationship with the other user. For example, the display device 2a outputs a voice such as "the person lined up behind the red clothes" as instruction information. As a result, it becomes possible to output instruction information to users who do not have characteristic information that can be uniquely identified by utterance from among multiple users, and appropriately select users who are suspected of having a fever. It becomes possible to isolate from the user of. Further, the display device 2a includes the identification feature including information on the clothes or belongings of another user and information indicating the relationship with the other user when the identification feature information is not extracted from the feature information of the user. Information may be generated. In addition, the above-mentioned positional relationship between the user who is determined to have an abnormal body temperature and another user may be used as identifiable information. Further, when the face information of the user is registered in advance in the office or the like, the user may be identified by face authentication and the name of the user may be used as the identification feature information.

It will be appreciated by those skilled in the art that various changes, substitutions and modifications can be made to this without departing from the spirit and scope of the invention. For example, the processes of the above-mentioned parts may be executed in different orders as appropriate within the scope of the present invention. Further, the above-described embodiments and modifications may be carried out in appropriate combinations within the scope of the present invention.
