How to use tof camera in smart door lock to complete face recognition?

ToF camera face recognition technology emits infrared light through the sensor, and the infrared light is reflected back to the sensor from the surface of the object. The sensor converts the information of the face through the phase difference between the emitted and reflected light, and the result will be more accurate. The texture of the object is affected, and the change of this structure is converted into depth information by the computing unit, which can accurately reconstruct the three-dimensional facial information of the user, which is very suitable for face recognition scenarios.
Tof camera is applied to smart door locks. How to complete human body sensing and AI face recognition efficiently, safely and accurately?
When people walk into the sensing range of the tof camera, the tof camera will start working immediately, and the intelligent processor will perform AI operations on the collected IR images and the slight changes in the face epidermis. The door lock can only be opened after the recognition and face recognition are completed. Smart door locks equipped with tof camera can truly prevent photos (including black and white photos), videos, 3D masks and other fake objects from being deceived.
