In recent years, with the widespread application of tof camera in smartphones, finance and other fields, people have a full understanding of tof camera technology, and it has also accelerated its application in other fields. Among them, tof camera has become one of the main recognition technologies for smart door locks.
So, how does the ToF camera perform facial recognition? ToF camera is used for facial recognition by using a laser transmitter to emit light pulses. After encountering an object, the light will be reflected, and then the ToF chip will capture the flight time of the light. The distance between the object and the lens can be determined by simple formula calculation.
Compared with other 3D facial recognition technologies, ToF camera for facial recognition technology has the advantages of fast response time, good adaptability to low-light environments, low power consumption, low cost, and small size. From these advantages, it can be seen that the fast response time and strong adaptability to low-light environments mean that the ToF camera will bring users a faster unlocking experience, and there is no need to worry about light affecting the unlocking; low power consumption means that the ToF camera will be used for smart door locks Bringing better battery life; and low cost means that it can bring a lower-cost 3D facial recognition solution to the smart door lock brand, so as to create a cost-effective 3D facial recognition smart lock product.
