Realize.
[Description of operation]
Next, the operation of the present embodiment will be described in detail.
[Operation when calling elevator]
First, the operation when calling an elevator without using the elevator call buttons 3-1 to 3-n will be described.
  Conventionally, when calling an elevator to a use start floor (for example, lobby; first floor), the elevator call button 3-1 had to be operated. However, in this embodiment, the user uses the elevator door 21-1. The elevator can be called only by looking at the camera outside the car 1-1 attached above the car.
  When the user looks at the outside camera 1-1 installed on the use start floor, the front face image of the user is picked up by the outside camera 1-1, and the image data including the front face image is the face image. It is sent to the detection unit 4.
  The face image detection unit 4 performs the processing shown in the flowchart of FIG. 6 with the cameras outside the cars 1-1 to 1-n on each floor being sequentially processed.
  When the external camera 1-1 installed on the first floor is set as a processing target, the face image detection unit 4 inputs image data sent from the external camera 1-1 for one screen (step S61, S62). Thereafter, the face image detecting unit 4 checks whether or not a front face image exists in the input image data (step S63). If a front face image can be detected (YES in step S63), a call signal indicating that the elevator has been called on the first floor is output to the elevator control unit 5 (step S64). On the other hand, when the front face cannot be detected (NO in step S63), the next outside camera (for example, the outside camera 1-2 installed on the second floor) is set as a processing target. The same processing is performed. In the case of this example, when the outside-car camera 1-1 installed on the first floor is set as the processing target, the determination result in step S63 is YES, and the elevator control unit 5 has the elevator waiting on the first floor. An elevator call signal indicating that there is a problem is output (step S64).
  Here, various methods can be adopted as the front face image detection method performed in step S63. For example, the input image data includes a portion that is recognized as a black eye, and between the two black eyes. If the distance is within a predetermined range, a method that the front face image can be detected can be employed. Here, the reason why the call signal is output only when the front face image can be detected is to prevent the elevator from being called depending on the face image by a passerby who has passed in front of the elevator.
  On the other hand, the elevator control unit 5 moves the elevator car to the first floor when a call signal indicating that there is an elevator waiting person on the first floor is sent from the face image detection unit 4. As a matter of course, the elevator controller 5 performs the same processing when a call signal is sent from the elevator call buttons 3-1 to 3-n.
  In addition, although the above-mentioned description is operation | movement when calling an elevator to the 1st floor, the same operation | movement is performed also when calling an elevator to another floor.
  As described above, according to the present embodiment, the user can call the elevator to the use start floor without operating the elevator call button 3-1, and both hands are blocked. Even so, the elevator can be easily called. Further, in the present embodiment, when the front face image is detected, the elevator is called, so that it is a person other than the specific person who registered the face information in the face information / user ID correspondence unit 6. However, the elevator can be called without operating the elevator call button.
[Operation when moving to the destination floor]
Next, an operation when a user in the elevator car moves to the destination floor will be described.
  When a user in an elevator car goes to the destination floor, it has been conventionally necessary to operate the destination floor designation button unit 11 provided in the elevator car and designate the destination floor. With respect to the specific person (face information / user ID correspondence unit 6, user ID / user who registers the face information and destination floor in the destination floor correspondence unit 9) who has got on the lobby, the elevator door The destination floor can be designated simply by looking at the in-car camera 10 attached above.
  First, the operation when a specific person gets into the elevator car from the lobby will be described. In the following description, it is assumed that two persons, the specific person U1 to whom the user ID “UID1” is assigned and the specific person U2 to which the user ID “UID2” is assigned, get on the elevator from the first floor.
  When the specific persons U1 and U2 designate the destination floor without operating the destination floor designation button unit 11, the specific persons U1 and U2 look at the in-car camera 10 after getting on the elevator car. Thereby, the in-car camera 10 captures the front face images of the specific persons U1 and U2, and outputs image data including the front face images of both U1 and U2 to the face authentication unit 7.
  After that, when the elevator door is closed, the face authentication unit 7 performs the processing shown in the flowchart of FIG. First, in step S71, it is determined whether or not the floor where the elevator door is closed is the lobby (first floor) (step S71). In this example, since it is the first floor, the determination result in step S71 is YES.
  If the determination result in step S71 is YES, the face authentication unit 7 inputs image data from the car camera 10 (step S72). Thereafter, the face authentication unit 7 pays attention to one front face image existing in the image data (step S73). Suppose that attention is paid to the front face image of the specific person U1.
  Thereafter, the face authentication unit 7 searches the face information / user ID correspondence unit 6 to check whether or not face information corresponding to the front face image of the specific person U1 is registered (step S75). If registered (YES in step S76), the user ID registered in association with the face information is output to the destination floor designating unit 8 (step S77), and then the next front face image is displayed. Pay attention (step S73). On the other hand, when it is not registered (step S76 is NO), attention is paid to the next front face image (step S73).
  In the case of this example, the face information “KD1” corresponding to the front face image of the specific person U1 is registered in the face information / user ID corresponding unit 6 (YES in step S76). After the user ID “UID1” (see FIG. 4) of the person U1 is output to the destination floor designation unit 8 (step S77), attention is paid to the next front face image (front face image of the specific person U2) (step S73). . Since the face information “KD2” corresponding to the front face image of the specific person U2 is also registered in the face information / user ID correspondence unit 6 (YES in step S76), the face authentication unit 7 uses the user of the specific person U2 The ID “UID2” is output to the destination floor designation unit 8 (step S77). When the authentication process for the front face images of the specific persons U1 and U2 is completed, there is no unfocused front face image (NO in step S74), and the face authentication unit 7 ends the process.
  Each time the destination floor designation unit 8 outputs a user ID from the face authentication unit 7, the destination floor designation unit 8 performs the processing of the flowchart of FIG. 8.
  When the user ID “UID1” of the specific person U1 is output from the face authentication unit 7, the destination floor designating unit 8 searches the user ID / destination floor correspondence unit 9 and associates it with the user ID “UID1”. The registered destination floor “7th floor” (see FIG. 5) is acquired (step S81). Thereafter, the destination floor “seventh floor” searched in step S81 is output to the elevator control section 5, and further, the button for the seventh floor provided in the destination floor designation button section 11 is output to the lighting section 12. The lighting is instructed (steps S82 and S83). Here, the reason why the button for the seventh floor is lit is to allow the specific person U1 to recognize that the designation of the destination floor by the face recognition has been normally performed. If the 7th floor button does not light, the specific person U1 determines that the designation of the destination floor by face authentication has failed, and the 7th floor button provided in the destination floor designation button unit 11 is determined. Operate the button.
  Further, the destination floor designating unit 8 performs the same process when the user ID “UID2” of the specific person U2 is sent from the face authentication unit 7, and the destination floor “20th floor” is sent to the elevator control unit 5. (See FIG. 5) is output, and the lighting unit 12 is instructed to turn on a button for the 20th floor (steps S81 to S83).
  When the destination floor “7th floor” and “20th floor” are sent from the destination floor designating section 8, the elevator controller 5 moves the elevator car to the 7th floor and the 20th floor.
  Next, the operation in the case of getting into an elevator car from a floor other than the lobby will be described.
  When the elevator door is closed on a floor other than the lobby (NO in step S71), the face authentication unit 7 determines whether or not the destination floor designation button unit 11 has been operated until the current time after stopping on that floor. Judgment is made (step S78). If it is determined that the operation has not been performed (NO in step S78), the destination floor “lobby” is output to the destination floor designating unit 8, and then the process ends. On the other hand, if it is determined that it is being operated (YES in step S78), the process is immediately terminated.
  When the destination floor “Lobby” is sent from the face authentication unit 7, the destination floor designating unit 8 outputs the destination floor “Lobby” to the elevator control unit 5 as shown in the flowchart of FIG. 9. The lighting unit 12 is instructed to turn on the lobby button (steps S91 and S92).
  Thereby, the elevator control part 5 moves an elevator car to a lobby, and the lighting part 12 lights the button for lobby. In addition, when step S78 becomes YES, the destination floor corresponding to the button operated to the elevator control part 5 from the destination floor designation | designated button part 11 is notified, and the elevator control part 5 is notified of this notified destination floor. Move the elevator car to
[Other Embodiments]
Next, a second embodiment according to the present invention will be described. The present embodiment is characterized in that a destination floor according to a time zone can be designated.
  FIG. 10 is a block diagram showing an example of the overall configuration of the second embodiment. The difference from the first embodiment shown in FIG. 1 is that a clock 14 is added, and a destination floor designation unit. 8 is provided with a destination floor designation unit 8a instead of 8, and a user ID / destination floor correspondence unit 9a instead of the user ID / destination floor correspondence unit 9.
  In the user ID / destination floor correspondence unit 9a, as shown in FIG. 11, a destination floor for each time zone is registered in association with the user ID. In the example of the figure, the destination floor for each time zone “0 to 6 o'clock, 6 o'clock to 12 o'clock, 12 o'clock to 18 o'clock, 18 o'clock to 24 o'clock” of the user with the user ID “UID1” is “ 7th floor, 7th floor, 7th floor, 2nd floor ".
  The destination floor designating unit 8a performs substantially the same operation as in the flowchart of FIG. 8, but performs the following processing instead of step S81. When the user ID of the specific person is input from the face authentication unit 7, the current time is input from the clock 14. Thereafter, the user ID / destination floor corresponding unit 9a is searched using the user ID as a key, and the destination floor corresponding to the current time among the destination floors registered for the user ID in each time zone. To get. The other operations are the same as those in the first embodiment.
  Next, a third embodiment according to the present invention will be described. The present embodiment is characterized in that a destination floor corresponding to a day of the week can be designated.
  In the present embodiment, instead of the user ID / destination floor correspondence unit 9a, the destination floor for each day of the week is registered in association with the user ID as shown in FIG. This is realized by providing a unit 9b, using a clock having a day of the week display function as the clock 14, and causing the destination floor designating unit 8a to perform the following processing instead of step S81. When the user ID of the specific person is input from the face authentication unit 7, the day of the week is input from the clock 14. Thereafter, the user ID / destination floor corresponding unit 9b is searched using the user ID as a key, and the destination floor corresponding to today's day of the destination floor of each day registered corresponding to the user ID. To get. The other points are the same as those in the first embodiment.

  FIG. 13 is a block diagram showing an example of the overall configuration of the present embodiment. The difference from the first embodiment shown in FIG. 1 is that a face authentication unit 7 c is provided instead of the face authentication unit 7. In terms of having a destination floor designation unit 8c instead of the destination floor designation unit 8 and having a user ID / destination floor correspondence unit 9c instead of the user ID / destination floor correspondence unit 9 is there.
  In the user ID / destination floor correspondence section 9c, as shown in FIG. 14, a destination floor corresponding to the use start floor is registered in association with the user ID. In this example, when the specific person with the user ID “UID1” gets in the lobby, “7th floor” is automatically designated as the destination floor, and when he gets on other than the lobby, “Lobby” is designated as the destination floor.
  The face authentication unit 7c is different from the face authentication unit 7 shown in FIG. 1 in that the process shown in the flowchart of FIG. 15 is performed each time the elevator door is closed. The only difference between the flowchart of FIG. 15 and the flowchart of FIG. 7 performed by the face authentication unit 7 is that the processes in steps S71, S78, and S79 are eliminated, and the other processes are exactly the same. .
  The destination floor designating unit 8c performs substantially the same processing as in the flowchart of FIG. 8, but performs the following processing instead of step S81. When the user ID of the specific person is input from the face authentication unit 7c, the user ID / destination floor correspondence unit 9c is searched using the user ID as a key. After that, the destination floor corresponding to the use start floor is acquired from the destination floors registered corresponding to the user ID. The other operations are the same as those in the first embodiment.
  In the embodiment described above, the cameras outside the car 1-1 to 1-n are attached in the vicinity of the operation state indicators 2-1 to 2-n, but may be attached to the elevator door. Although not described in the above-described embodiment, the registration method of the face information to the face information / user ID correspondence unit 6 and the user ID / destination floor correspondence units 9, 9a, 9b, 9c is arbitrary. This method can be adopted. For example, the face image necessary for generating the registered face information may be captured using the outside cameras 1-1 to 1-n and the in-car camera 10, or may be captured using another camera. You may do it. In the above-described embodiment, the face information / user ID correspondence unit 6 and the user ID / destination floor correspondence units 9, 9a, 9b, 9c are used, but the destination floor is associated with the face information. May be used.
