The technical scheme of the existing face recognition system is generally divided into two types. The first type is to set a face recognition server near a video or image collection device, and directly transmit the collected video or image to the server through a data cable, so that the server recognizes and compares the face. The other method is to send the processed video or image to a remote face recognition server through the Internet or a data dedicated line for face recognition and comparison.

[0003] However, the above two face recognition methods use a single camera, which cannot shoot a wider angle, and the camera device is generally fixed and cannot be adjusted in angle. The fixed camera device cannot be adjusted in angle, so that users of different heights and body types may not be able to face the camera from the correct angle, affecting the recognition effect. To solve the above problems, a camera angle adjusting device based on identification function is proposed. UTILITY MODEL CONTENT
