![]() ![]() The performance is poor in strong light environment and easily affected by light. ![]() However, the range of the structured light solution is affected by the light spot pattern, and the obstacle avoidance range is small. The image sensor captures the deformed pattern, and then calculates the deformation of each pixel in the captured pattern to obtain the corresponding parallax and thus the depth value. Five mainstream obstacle avoidance technologies for sweeping robotsġ, first of all, the 3D structured light solution, the principle is to use infrared light source, the light emitted after a certain code projection on the object, these patterns reflected back by the surface of the object, with the object distance will be different deformation, the image sensor will be deformed after the pattern photographed. ![]()
