Description
Technical Field
The invention relates to a calling system with face recognition, in particular to a calling system with two face recognition modules.
Background
Face recognition, as a means of authority identification, is widely used in a variety of different fields, including the elevator field. In the existing elevator system, a call panel is provided with a face recognition module and a display screen, after a person presses a call key (an upper arrow key and/or a lower arrow key), the display screen is lightened, the face recognition module executes a face recognition program later, if the valid authorized face data is recognized, the corresponding call key is lightened to indicate that the call is successful, otherwise, the person is informed of the failure of the call through the display screen, and the call key cannot be lightened.
However, the position of the existing call panels is fixed, which presents a problem: the face feature camera and the environment camera on the face recognition module are fixedly oriented to the normal head position of the adult, when the head height of some persons with low ground clearance is not high, such as: children, a person who sits in a wheelchair, and the like suffer from great troubles when they want to perform face recognition operations, which makes it inconvenient for them to take an elevator.
Therefore, there is a need for improvements to existing face recognition call systems.
Disclosure of Invention
The invention provides a calling system which can smoothly identify the faces of people with different heights.
The following technical scheme is adopted:
a calling landing system with double face recognition modules comprises a first face recognition module, a main control circuit, a display screen and a calling landing key, wherein a first face characteristic camera and a first environment camera are arranged on the first face recognition module; the first facial feature camera, the first environment camera, the display screen and the calling landing key are all communicated to the main control circuit; particularly, the system further comprises a second face recognition module, wherein a second face feature camera and a second environment camera are arranged on the second face recognition module; the first face recognition module faces to a higher direction, and the second face recognition module faces to a lower direction; after a person presses a call key, a first face recognition module is started to perform shooting and face recognition, at the moment, the main control circuit sends an image of a first environment camera to a display screen for displaying, and timing is started after T1 time delay; before the time delay T1 is over, if any authorized human face is not recognized and the call key is not pressed again, the man-machine interaction is over after the time delay T1 is over; before the end of the delay T1, if the authorized face is identified, the delay T1 is counted again; before the time delay T1 is over, if no authorized human face is recognized and the call key is pressed again, the first human face recognition module is closed, the second human face recognition module is started to carry out shooting and face recognition, the main control circuit sends the image of the second environment camera to the display screen for display, and the time delay T2 starts to time; before the time delay T2 is over, if any authorized human face is not recognized and the call key is not pressed again, the man-machine interaction is over after the time delay T2 is over; before the end of the delay T2, if the authorized face is identified, the delay T2 is counted again; before the time delay T2 is over, if no authorized human face is recognized and the call key is pressed again, the second human face recognition module is closed, the first human face recognition module is started to perform image pickup and face recognition, the main control circuit sends the image of the first environment camera to the display screen for display, the time delay T1 starts timing again, and the judgment condition after the time delay T1 starts timing is executed.
The delay T1 and the delay T2 may be the same duration.
The working principle of the system is as follows: the first face recognition module is preferably oriented to a position where a healthy adult's head is normally located, while the second face recognition module is oriented to a child or wheelchair-bound person. Therefore, as long as a person presses the call calling key before the time delay T1 or the time delay T2 is finished, the main control circuit can be switched to the second face recognition module/the first face recognition module to carry out image pickup and face recognition as long as the first face recognition module/the second face recognition module does not recognize any authorized face, so that healthy adult people, children and people sitting in a wheelchair can be conveniently operated and used. At this time, since the display screen is simultaneously switched to the image of the corresponding environment camera, the person can easily know which face recognition module is working at the moment.
The invention has the following advantages:
1) the utility model can be adapted to the people with higher and lower height, and the use is convenient; 2) compared with the prior art that no new key is added, the manual operation is easy for personnel; 3) the equipment is convenient to use without increasing much cost.

Detailed Description
The present invention will be further described with reference to the following examples.
As shown in fig. 1, the face recognition system of the present embodiment is built on a first floor elevator call panel. The call panel 1 is provided with a display screen 11, a call key 12, a first face recognition module 13 and a second face recognition module 14, and a main control circuit is arranged in the call panel 1. The first face recognition module 13 is provided with a first face feature camera 131 and a first environment camera 132. The second face recognition module 14 is provided with a second facial feature camera 141 and a second environmental camera 142. The first facial feature camera 131, the first environment camera 132, the second facial feature camera 141, the second environment camera 142, the display screen 11 and the call key 12 are all connected to the main control circuit.
The biggest difference between the call panel with the face recognition function of the embodiment and the existing call panel with the face recognition function is that: the call panel of this embodiment is provided with 2 sets of face recognition modules. The first face recognition module faces in a higher direction and is set for face recognition of a healthy adult population; the second face recognition module faces in a lower direction and is configured to recognize the face of a child or a wheelchair-sitting crowd.
After the above hardware conditions are met, the control logic of the present embodiment is as follows:
at ordinary times, the main control circuit is in a standby state, and the display screen is also closed. After a person presses a call key, the first face recognition module is started and immediately enters the working state of environment shooting and face recognition, simultaneously, the main control circuit sends the image of the first environment camera to the display screen for displaying, and the time delay T1 in the program of the main control circuit starts to time. Before the time delay T1 is over, if no authorized human face is recognized and the call key is not pressed again, the time delay T1 is over, the man-machine interaction is over, the main control circuit enters a standby state, and the display screen is also closed. Before the end of the delay T1, if an authorized face is identified, the delay T1 is re-timed. Before the time delay T1 is over, if no authorized human face is recognized and the call key is pressed again, the first human face recognition module is closed, the second human face recognition module is started to perform image pickup and face recognition, the main control circuit sends the image of the second environment camera to the display screen for display, and the time delay T2 in the program of the main control circuit starts to time. Before the time delay T2 is over, if any authorized human face is not recognized and the call key is not pressed again, the time delay T2 is over, the man-machine interaction is over, the main control circuit enters a standby state, and the display screen is also closed. Before the end of the delay T2, if an authorized face is identified, the delay T2 is re-timed. Before the time delay T2 is over, if no authorized human face is recognized and the call key is pressed again, the second human face recognition module is closed, the first human face recognition module is started to perform image pickup and face recognition, the main control circuit sends the image of the first environment camera to the display screen for display, the time delay T1 starts timing again, and the judgment condition after the time delay T1 starts timing is executed.
The delay T1 and the delay T2 of the present embodiment are both set to 20 seconds.
When a healthy adult needs to perform a call operation, in a standby state of a call panel, the adult/she only needs to press a call key, then observes an environment picture on a display screen, and slightly adjusts the position of the face of the adult/man according to the prompt of the picture so as to quickly complete the call operation.
For the children or the wheelchair-sitting person to carry out the calling operation, in the standby state of the calling panel, the children/the wheelchair-sitting person can easily find that the children/the wheelchair-sitting person is not in the picture by pressing the calling key and then observing the environment picture on the display screen, and at the moment, the children/the wheelchair-sitting person can quickly finish the calling operation by pressing the calling key again and starting the second face recognition module facing to the lower direction, and at the moment, the children/the wheelchair-sitting person can find that the children/the wheelchair-sitting person is in the picture, and then slightly adjusting the position of the face of the children/the wheelchair-sitting person according to the.
The description is only a preferred embodiment of the invention, and all technical equivalents which come within the spirit and scope of the invention are intended to be protected.
