Therefore, the normal use of adults and children is ensured.
The camera is normally opened, and under the standby condition of identity authentication, the camera also runs at the background to capture the face in real time. The human face is captured by the camera, and in order to reduce standby power consumption, the sampling interval of the capturing camera can be set to 250ms once, namely, 4 frames of data are acquired from the camera within 1 second.
Step S12: when the identity authentication device monitors that a human face approaches, the screen of the identity authentication device is controlled to be opened.
When the identity authentication device monitors that a human face approaches, the screen of the identity authentication device is controlled to be opened, and the identity authentication device is controlled to exit from a sleep state and enter into an awakening state.
Step S13: the identity verification device detects whether the face is a living body.

The screen can be awakened after the frame which accords with the face recognition exists, at the moment, the user can see the user, and the living body detection is carried out according to the captured face.
Then, living body detection is needed to judge whether the human body is a real person or not, and false living bodies such as an electronic screen and a photo are filtered out.
Step S14: when the identity authentication device detects that the human face is a living body, whether a human face image matched with the human face exists in the database or not is judged.
The database is stored in the local identity verification device, so that the identification speed can be improved.
Step S15: if the database has the face image matched with the face, the identity verification device generates a verification passing instruction and sends the verification passing instruction to the gate to allow the gate to be opened.
Based on the above problem of waking up the panel by infrared sensing, it is proposed to wake up the screen and quickly complete face authentication using face recognition.
