The display unit 34 displays an image or the like based on a display signal output from the control unit 31 . The display unit 34 is configured using, for example, a liquid crystal display panel or an organic EL display panel.

The face authentication camera 35 is arranged above the display unit 34, captures an image of a subject in a predetermined field angle area in front of the camera at a predetermined frame rate and a predetermined resolution, and generates image data of the captured image (captured image). and outputs the generated image data to the control unit 31 . The face authentication camera 35 is an example of an imaging unit. The predetermined angle of view area is set to an angle of view that allows the faces of each user to be captured when two or three users who want to register their destination floors are in front of the destination floor registration device 30 . ing. The predetermined resolution may be any resolution at which face detection and face matching can be performed appropriately during face authentication, and may be HD, FHD, 4K, or the like, for example. The frame rate may be any rate, such as 15 fps or 30 fps.

FIG. 5 is a diagram showing the configuration of the user DB stored in the storage unit 12 of the group supervisory control device 10. As shown in FIG.

The user DB records the default destination floor in association with the face data of the user. Registration of such information in the user DB is performed by, for example, an elevator manager or a building manager.

“Face data” is data used in face authentication of the user. The “face data” may be face image data (face image data) or face feature point data (face feature point data), as long as the face of the user can be distinguished. However, the case where the "face data" is face feature point data will be described below. Facial feature point data is, for example, data indicating the position and shape of the eyes, eyebrows, nose, mouth, etc., and features such as the outline of the face. The facial feature point data can be generated based on the facial photograph provided by the user for registration in the user DB or the facial image data of the user captured for registration.

The “default destination floor” is a destination floor designated in advance by a user or the like. For example, the living floor of the user is set as the default destination floor.

In the example shown in FIG. 5, "12" is registered as the default destination floor in association with face data 1, and "15" is registered as the default destination floor in association with face data 2. FIG. For the rest of the facial data, similarly, default destination floors are registered in association with the facial data.

2. Elevator System Operation The operation of the elevator system will now be described in more detail with reference to flowcharts.

FIG. 6 is a flow chart explaining the operation of the destination floor registration device 30. As shown in FIG.

The control unit 31 of the destination floor registration device 30 causes the display unit 34 to display usage guidance information (S10).

FIG. 7 is a diagram showing an example of usage guidance information. In FIG. 7, a message "Please perform face authentication when using the elevator" is displayed as the usage guidance information.

Returning to FIG. 6, the control unit 31 of the destination floor registration device 30 determines whether or not the captured image output from the face authentication camera 35 includes a face (S11). Specifically, face detection processing is performed on the image data of the captured image. Note that the control unit 31 can detect a predetermined number of faces included in the captured image. The predetermined number can be arbitrarily set, but is, for example, three.

When the face is not included in the captured image (NO in S11), that is, when the face is not detected, the controller 31 of the destination floor registration device 30 executes the process of step S11 again.

If a face is included in the captured image (YES in S11), the control unit 31 of the destination floor registration device 30 generates an allocation request signal including face data of the departure floor and all detected faces, and performs group management. It is transmitted to the control device 10 (S12). The installation floor of the destination floor registration device 30 is used as the departure floor. The “face data” here may be face image data (face image data) or face feature point data (face feature point data), as long as the face of the user can be distinguished. However, in the following description, the “face data” is assumed to be face feature point data. Face data for transmission (facial feature point data) is acquired by analyzing the captured image when it is determined in step S11 that a face is included. By transmitting the facial feature point data to the group supervisory control device 10, the group supervisory control device 10 does not need the process of acquiring the facial feature point data from the image data of the captured image.

The control unit 31 of the destination floor registration device 30 determines whether or not an allocation result signal including the destination floor arrangement, the allocated car name, and the group flag grpFG has been received from the group supervisory control device 10 (S13). The destination floor array is a function that stores values of destination floors, and can store values for each of a plurality of destination floors. Destination floor values are indicated by numerical values such as 1, 2, and 3, for example.

When the allocation result signal is received (YES in S13), the control section 31 of the destination floor registration device 30 determines whether or not the group flag grpFG is "YES" (S14). If the group flag grpFG is "YES", it means that group registration has been performed for a plurality of users.

If the group flag grpFG is "YES" (YES in S14), the control unit 31 of the destination floor registration device 30 causes the display unit 34 to display the allocation result information and the group registration information for a certain period of time (S15). The certain period of time is a period of time during which the user can appropriately recognize the displayed content, and is, for example, 3 seconds. The allocation result information is information indicating the destination floor and the allocated car. Group registration information is information indicating that all destination floors of a plurality of users forming a group have been collectively assigned to one elevator (elevator). Such assignments are hereinafter referred to as "group assignments".

8A and 8B are diagrams showing examples of display of allocation result information and group registration information. FIG. 8A illustrates a case where the face image of the user whose face has been detected is displayed in the face image display area A1 on the right side, and the allocation result information and group registration information are displayed in the message display area A2 on the left side. there is This example shows an example in which the faces of two users are detected. A rectangular frame indicating detection is displayed superimposed on each detected face. As the allocation result information, the information of the destination floor and the allocated car is displayed. FIG. 8A illustrates a case where the destination floor (default destination floor) is the 12th floor and the assigned elevator is the first elevator. As group registration information, characters "group registration" are displayed.

FIG. 8B shows an example in which the destination floors of two users whose faces are detected are different. When the destination floors (default destination floors) of multiple users whose faces have been detected are different, each destination floor is displayed. In this example, the destination floor (default destination floor) of one user is the 12th floor, and the destination floor (default destination floor) of another user is the 15th floor.

If the group flag grpFG is not "YES" (NO in S14), that is, if grpFG is "NO", the control unit 31 of the destination floor registration device 30 causes the display unit 34 to display the allocation result information for a certain period of time (S16 ). If the group flag grpFG is "NO", it means that group registration is not performed. Therefore, unlike step S15, the characters "group registration" are not displayed. The certain period of time is a period of time during which the user can appropriately recognize the displayed content, and is, for example, 3 seconds.

8C and 8D are diagrams showing examples of display of allocation result information. The group flag grpFG becomes “NO” when, for example, as shown in FIG. This is the case where there are a plurality of users who have been authenticated, and at least one of them has been successfully face-recognised. FIG. 8D shows an example in which face recognition was not successful for one of two persons whose faces were detected. In this case, only the destination floors (default destination floors) of users whose face authentication has succeeded are displayed.

In step S13, if the allocation result signal has not been received (NO in S13), the control section 31 of the destination floor registration device 30 determines whether or not an error signal has been received from the group supervisory control device 10 (S17). .

If no error signal has been received (NO in S17), the control unit 31 of the destination floor registration device 30 returns to the determination in step S13.

If an error signal has been received (YES in S17), the control unit 31 of the destination floor registration device 30 causes the display unit 34 to display error information for a certain period of time (S18). Error information is information for notifying that an elevator cannot be assigned to a user who has undergone face authentication. The certain period of time is a period of time during which the user can appropriately recognize the displayed content, and is, for example, 3 seconds.

FIG. 8E is a diagram showing an example of display of error information. FIG. 8E illustrates a case where the faces of two users are detected, but the face authentication of neither of them succeeds, and the error information "You cannot use the elevator" is displayed. .

FIG. 9 is a flow chart explaining the operation of the group supervisory control device 10. As shown in FIG. Processing based on this flowchart is executed for each destination floor registration device 30 . That is, each destination floor registration device 30 is processed in parallel.

The control unit 11 of the group supervisory control device 10 determines whether or not an allocation request signal has been received from the destination floor registration device 30 (S31).

If the allocation request signal has not been received from the destination floor registration device 30 (NO in S31), the control unit 11 of the group supervisory control device 10 executes the determination of step S31 again.

When receiving an allocation request signal from the destination floor registration device 30 (YES in S31), the control section 11 of the group supervisory control device 10 sets the number of face data included in the allocation request signal as the number of face data N (S32 ).

The control unit 11 of the group supervisory control device 10 initializes the group user number npsg to 0, and also initializes the counter i to 1 (S32). The number of group users npsg is the number of users assigned simultaneously as a group. The counter i is a counter for the number of users being processed (the number of face data being processed).

The control unit 11 of the group supervisory control device 10 determines whether face data matching the i-th face data included in the allocation request signal to a predetermined extent or more is registered in the user DB (S34). That is, face authentication is performed on the face associated with the face data included in the allocation request signal. Various known methods can be used to compare face data for this determination. For example, the face data (facial feature point data) included in the allocation request signal and each face data (facial feature point data) registered in the user DB are sequentially compared (verified) to obtain the matching rate. Then, it is determined whether face data having a matching rate equal to or higher than a predetermined matching rate with respect to the face data included in the allocation request signal is registered in the user DB. When face data having a matching rate equal to or higher than a predetermined matching rate is registered in the user DB, the control unit 11 of the group supervisory control device 10 controls the use of the face data (facial feature point data) included in the allocation request signal. It determines that the person (the user whose face has been detected) is a user registered in the user DB, and determines that face authentication has succeeded.

If face data that matches the i-th face data to a predetermined extent or more is registered in the user DB (YES in S34), the control unit 11 of the group supervisory control device 10 adds 1 to the number of group users npsg. (S35).

The control unit 11 of the group supervisory control device 10 acquires the default destination floor linked to the registered face data from the user DB, and stores it in the destination floor array as the destination floor (S36).

The control section 11 of the group supervisory control device 10 adds 1 to the counter i (S37).

In step S34, if face data that matches the i-th face data to a predetermined extent or more is not registered in the user DB (NO in S34), the control section 11 of the group supervisory control device 10 executes step S37. do.

The control unit 11 of the group supervisory control device 10 determines whether or not the value of the counter i is greater than the number N of face data (S38).

If the value of the counter i is not greater than the number N of face data (NO in S38), the control section 11 of the group supervisory control device 10 repeats the processes after step S34.

When the value of the counter i is larger than the number of face data N (YES in S38), that is, when the processing of all face data is completed, the control unit 11 of the group management control device 10 determines that the number of group users npsg is 0. (S39).

When the number of group users npsg is 0 (YES in S39), the control unit 11 of the group supervisory control device 10 transmits an error signal to the destination floor registration device 30 which is the transmission source of the allocation request signal (S40), and step Return to the processing of S31. The destination floor registration device 30 that is the transmission source of the allocation request signal can be appropriately specified by including the device ID of the destination floor registration device 30 in the allocation request signal.

If the group user number npsg is not 0 (NO in S39), the control unit 11 of the group supervisory control device 10 determines whether or not the group user number npsg is 1 (S41).

When the group user number npsg is 1 (YES in S41), the control unit 11 of the group supervisory control device 10 sets "NO" to the group flag grpFG.

The control unit 11 of the group supervisory control device 10 allocates a single (one) destination floor stored in the destination floor array to any one car (elevator) (S43). As an allocation method for performing this allocation, a known allocation method in the platform destination floor registration method can be appropriately used.

In step S41, if the group user number npsg is not 1 (NO in S41), the control section 11 of the group supervisory control device 10 sets "YES" to the group flag grpFG (S44).

The control unit 11 of the group supervisory control device 10 collectively allocates all the destination floors stored in the destination floor arrangement to one car (elevator) (S45). In other words, group allocation is performed. Specifically, the control unit 11 of the group supervisory control device 10, for example, when all the destination floors stored in the destination floor arrangement are assigned to any one elevator, the total waiting time in the elevator or service completion The total time is obtained for each elevator, and all the destination floors stored in the destination floor array are actually allocated to the elevator with the smallest total waiting time or service completion time. According to this allocation method, all the destination floors stored in the destination floor arrangement can be allocated to any one elevator while suppressing adverse effects on elevator operation efficiency. In addition, when not all the destination floors stored in the destination floor array, but only one destination floor among all the destination floors is assigned to any one elevator, the sum of the waiting times in the elevator concerned or The sum of service completion times is obtained for each elevator, and all the destination floors stored in the destination floor array are actually assigned to the elevator with the smallest sum of the obtained waiting times or the sum of service completion times. good too. According to this allocation method, the amount of calculation in the control section 11 of the group supervisory control device 10 can be reduced, and the allocation speed is improved.

After execution of step S43 or S45, the control unit 11 of the group supervisory control device 10 transmits an allocation result signal including the destination floor arrangement, the allocated car name, and the group flag grpFG to the destination floor registration device that transmitted the allocation request signal. (S46), the process returns to step S31.

3. Actions/Effects, etc. Actions/effects, etc. of the present embodiment will be described. When using the elevator of this embodiment, the user first goes in front of the destination floor registration device 30 . The destination floor registration device 30 repeatedly performs face detection processing on the captured image captured by the face authentication camera 35 at regular time intervals. information on the floor where the destination floor registration device 30 is installed) and an allocation request signal including the generated face data is transmitted to the group supervisory control device 10 . The group supervisory control device 10 determines whether or not face data matching a predetermined degree or more is registered in the user DB for each of the face data included in the received allocation request signal. The data of the default destination floor linked to the face data is obtained from the user DB.

Here, in the elevator system of the present embodiment, when the faces of a plurality of users are detected from the captured image, these users are collectively assigned to one elevator (group assignment). When the faces of multiple users are detected from the captured image, it is highly likely that these users are people (groups) with a certain close relationship, such as friends, colleagues, and acquaintances. Therefore, when a plurality of faces are detected from the captured image, group assignment is performed to collectively assign these users to one of the elevators. Such group assignment prevents users having a close relationship from being assigned to different elevators, realizing assignment that is highly convenient for users. In addition, in this allocation method, since it is not necessary to register relationships between users in advance in a database or the like, it is possible to obtain the above effects while suppressing complication of the system.

Also, when a plurality of users detected from the captured image are group-assigned to one elevator, the display unit 34 of the destination floor registration device 30 displays group registration information "group registration". Therefore, these users can safely board one elevator. On the other hand, when at least one of the detected faces is not registered in the user DB, the group registration information "group registration" is not displayed. can recognize that

In addition, according to the elevator system of the present embodiment, since the destination floor is registered by face authentication in the destination floor registration device 30, there is no need to perform a touch operation on the numeric keypad, etc. Infection with infectious diseases can be suppressed.

(Other embodiments)

In the above-described embodiment, the image shown in FIG. 8B is illustrated as an example in which a plurality of faces are included in the captured image. may come within the angle of view of For example, a little after the timing when the face of the first user among the plurality of users forming the group is detected, the second user enters the angle of view of the face recognition camera 35. Faces may be detected. In such a case, it is preferable to group these two users into one elevator. In order to realize this, when the face of the first user is detected in step S11, the process of step S12 is not performed immediately, but a predetermined time after the face of the first user is detected. (for example, 1 second to 2 seconds), the face detection process is continued, and each time a second or subsequent face is detected within a predetermined time, face data of the detected face is generated. You may make it process. In other words, an allocation request signal containing face data of the face of the first user and face data of all faces detected within a predetermined time period may be sent to the group supervisory control device 10 . Thus, even when a plurality of users forming a group enter the angle of view of the face authentication camera 35 at slightly different timings, the plurality of users are group-assigned to one elevator. be able to.

Further, when a plurality of faces are detected from the captured image, the control section 31 may include only face data of some faces in the allocation request signal. For example, when a plurality of faces are detected from a captured image, only users whose faces have a size equal to or larger than a predetermined size ratio to the largest face in the captured image are regarded as users forming a group, The allocation request signal may include only the face data of the largest face and the face data of the face having a size equal to or larger than a predetermined size ratio with respect to the largest face. Since the standing positions of the users forming the group tend to be in a relatively close positional relationship, the size of the face detected for these users is at least a predetermined size ratio with respect to the largest face. Probability is high. On the other hand, the standing positions of users who do not form a group tend to be relatively distant from the users who form a group. It is considered that it will be smaller than the faces of the users forming the group. In this other embodiment, a group is formed by regarding only users whose face size is equal to or larger than a predetermined size ratio to the largest face in the captured image as users to form a group. It is more likely that only people will be assigned to one elevator collectively (group assigned). Here, the predetermined size ratio may be set based on, for example, the distance when users in a relatively close relationship, such as colleagues, approach each other. The predetermined size ratio is, for example, 70%. Note that the predetermined size ratio may be set in consideration of the angle of view of the lens of the face authentication camera 35 . As the angle of view of the lens increases, the difference in face size on the image becomes more conspicuous due to the effect of perspective enhancement. Therefore, the predetermined size ratio may be decreased.

In the above embodiment, the user DB is stored in the storage unit 12 of the group control device 10, but depending on the building, a security system using face authentication may be provided. Such a security system usually has a database that stores face data for face authentication and the like. Therefore, the data of the default destination floor may be registered in association with the face data of this database, and the group supervisory control device 10 may acquire the data of the default destination floor from this database.

In the above-described embodiment, the destination floor registration device 30 is arranged on the elevator hall of each floor or on the wall surface of the building in the vicinity thereof. A registration device 30 may be arranged. In this case, the opening and closing of the flapper of the security gate may be controlled based on the face recognition result in the group supervisory control device 10 .

In the above embodiment, the case where "face data" is face feature point data has been described. However, the invention is not so limited. The “face data” may be face image data. The format of the image data may be any format such as bmp format, jpg format, gif format, or the like. When "face data" is used as image data, face image data may be registered as "face data" in the user DB. In step S12 of FIG. 6, the destination floor registration device 30 transmits an allocation request signal including face image data as "face data" to the group supervisory control device 10. FIG. The image data of the face is acquired from the captured image, for example, when it is determined that the face is included in step S11.

(1) The elevator system of the embodiment includes:
An elevator system that assigns a destination floor to one of a plurality of elevators before boarding a user,
An imaging unit (for example, a face authentication camera 35) that images a user who is trying to register a destination floor;
a face detection unit (for example, the control unit 31 of the destination floor registration device 30) that performs face detection processing on the captured image captured by the imaging unit and generates face data of the detected face;
a storage unit (for example, a user DB stored in the storage unit 12 of the group control device 10) that stores in advance a default destination floor for each user in association with face data for face authentication;
an allocation unit (for example, the control unit 11 of the group supervisory control device 10) that allocates destination floors to elevators;
an output unit (for example, the control unit 31 of the destination floor registration device 30) that outputs an allocation request signal including the face data generated by the face detection unit to the allocation unit;
When the allocation request signal includes a plurality of face data, the allocation unit stores each default destination stored in association with face data for face authentication that matches each face data to a predetermined degree or more in the storage unit. Group allocation is performed to collectively allocate floors to one of the plurality of elevators (60).

This configuration can improve convenience when a plurality of users forming a group use the elevator.

(2) In the elevator system of the embodiment,
When the face detection unit (for example, the control unit 31 of the destination floor registration device 30) detects the face of the first person in the captured image and generates face data, the face detection unit performs face detection processing for a predetermined time after detection. and generating face data of the detected face each time a second or subsequent face is detected within the predetermined time,
The output unit (for example, the control unit 31 of the destination floor registration device 30) issues an allocation request including face data of the face of the first user and face data of all faces detected within the predetermined time. A signal is output to the allocation unit (for example, the control unit 11 of the group supervisory control device 10).

With this configuration, even when a plurality of users forming a group enter the angle of view of the face authentication camera 35 at slightly different timings, the plurality of users can be grouped together in one elevator. Can be assigned (group assignment).

(3) In the elevator system of the embodiment,
The output unit (for example, the control unit 31 of the destination floor registration device 30) estimates the size of the face on the captured image based on the generated face data for each face detected from the captured image. and the allocation unit ( For example, it is output to the control unit 11) of the group supervisory control device 10).

This configuration increases the possibility that only users forming a group will be collectively assigned to one elevator (group-assigned).
