Compared with traditional cameras, 3D depth camera can obtain depth information, which makes it more convenient and accurate to perceive the surrounding environment and changes. The depth camera has many application scenarios, and there are many shadows of the depth camera in our daily life. What can the 3D depth camera be used for? 3D modeling, unmanned driving, robot navigation, mobile phone face unlocking, somatosensory games, etc. all use depth cameras to achieve their functions. At present, the application of 3D depth camera has been unlocked by smart terminals and gradually extended to scenarios such as mobile payment and distance detection.
How 3D depth camera applied for smartphone to get depth values?
1. When face is close to the camera, first activate the proximity sensor, if it is close, it will send a signal to notify the flood illuminator
2.Infrared lens receives the reflected dot pattern, and calculates the deformation of the pattern to obtain the distance between different positions of the face.
