ToF sensor is one of the solutions of the 3D depth camera. The principle of distance measurement is between the lens and the object by lighting the target object.
Use these data to judge how far this object is from us, so as to know the distance of each object and realize the depth map.Finally, you can directly draw a stereo image to achieve 3D stereo depth sensing.
Different ToF sensor used different light sources, both LED and laser.The core component of the TOF 3D module is chip, which integrates many functions, including driving the projector, receiving the reflected light, and then generating the raw image, which is then sent to the software for processing into depth information.
ToF sensor is much longer than structured light, so it is more suitable for use in the rear camera of mobile phones for somatosensory games.
