[0017] Such as image 3 As shown, the face recognition device applied to guards includes an infrared camera 1 , a control circuit part 2 , a power cord 3 , and a housing 4 .
[0018] The control circuit part 2 includes a face recognizer, a memory, a door lock control module, and a microprocessor unit; the camera is connected with the face recognizer, the memory is connected with the face recognizer, the microprocessor is connected with the door lock control module, and the face The recognizer is connected to the microprocessor; the face recognizer receives the face information obtained by the camera, recognizes it, and compares it with the data stored in the memory, and outputs the result to the microprocessor unit, which is judged by the microprocessor unit. If the comparison is successful, the microprocessor controls the door lock control module to open the door lock.
[0019] Such as figure 2 As shown, the main work of the face recognizer includes image compression, imag...
