3D TOF cameras have been widely used in our daily life. In the automotive field, 3D TOF cameras are used for automatic driving, anti-collision automatic braking, gesture recognition and other functions. In addition, 3D TOF cameras are also used in mobile phone face recognition, camera focusing, and AR and VR functions in somatosensory games.
3D TOF camera is a non-scanning device. Its imaging is not like the point-by-point scanning method of traditional lidar, but it adopts a camera-like working mode to realize global imaging at one time to complete detection and imaging. Each pixel can record photon flight time. Since the object has three-dimensional space properties, the light irradiated on different parts of the object has different flight times, so a "three-dimensional" image with depth information is output.
The advantages of TOF cameras are high precision, excellent detection capabilities for small objects, and accurate mapping in complex environments. The detection range is not limited to the 2D plane, obstacle avoidance performance is better, and the response speed is faster. Compared with stereo vision solutions, 3D TOF cameras are not limited by the lighting environment, and can still work efficiently at night or in low-light environments. In addition, the detection distance of 3D TOF camera is better than that of structured light technology. Applicable to commercial scenarios with large areas.
