Due to the small size and high precision of the tof camera module, it is easy to be applied to various terminals, especially in the field of smart door locks. Due to the strong anti-counterfeiting and adaptability of the tof camera module, it is very suitable for the application of face recognition door locks.
Strong adaptability: It can also be used in the dark or in low light conditions. tof camera can capture the dynamic expressions of people and recognize changes in facial makeup.
Strong anti-counterfeiting: The user can complete the authentication without any action coordination. The authentication can be completed only by capturing a face portrait in front of the camera, and can effectively defend against attacks by various props such as paper, masks, and mobile phone screens.
Wide applicability: ToF camera face recognition technology can be widely used in face payment, security check and other fields.
