Introduction to the principle of 3D structured light


The hardware of the 3D structured light module is mainly composed of projector and camera. The projector will project specific structural information on the surface of the object to be tested. Then, the structured light image of the surface to be tested is photographed by the infrared camera, and the 3D data of the object to be tested is obtained through image analysis based on the principle of triangle ranging.

3D structured light is widely used in 3D reconstruction, 3D face recognition and living detection.
