When the smart door lock uses face recognition to unlock, it obtains face information through the 3D ToF camera, and combines the measurement method of the tof camera module to perform 3D discrimination and face comparison on the captured face. Generally, it can be seen in the process of experience that when registering and entering, there is no need for the face to turn left and right and look up and bow down. You only need to face the face to the camera, and use the 3D TOF camera outside the module to collect and record the face. three-dimensional information.
Collecting complete face contour and depth information through 3D ToF camera, combined with detection algorithm, can more effectively prevent false attacks such as photos, videos, masks, etc., with extremely high anti-counterfeiting. It is worth mentioning that the 3D tof camera has a good wide dynamic effect, whether it is strong light, backlight, or a completely dark environment, it can accurately recognize the face and quickly unlock it. Configuring 3D tof camera is one of the core advantages of smart door locks.
