Full name of TOF is Time of Flight.After the light of the modulated light source of the camera is emitted, it is reflected back by the object, and there will be a time difference. According to this time difference, through a specific algorithm, the distance of the object from the camera can be estimated.
As shown in the figure, the ToF camera greatly improves the image depth information, can analyze the front stereo image, and accurately recognize the distance between objects, so as to achieve high-precision robot avoiding obstacles, route planning and other functions in complex environments.
Tof sensors build a 3D depth camera. The tof camera greatly improves the image depth information, can analyze the front stereo image. A robot equipped with a ToF camera can perform three-dimensional modeling of the front image, so as to achieve high-precision robot avoidance, route planning and other functions in a complex environment. In addition, this 3D depth camera can also realize multiple functions such as face recognition, gesture recognition, 3D measurement, environment perception, 3D map reconstruction, etc., and can be widely used in TVs, mobile phones, robots, drones, and VR. /AR, smart home security, car driving assistance and other fields.
