Description

technical field [0001] The invention relates to the technical field of distance measurement, in particular to a rotating optical scanning distance measurement device and method. Background technique [0002] The optical scanning ranging device is a device for non-contact scanning ranging of the target object through structured light. Scanning the structured light beam to the environment through the rotating mechanism can realize the extraction of environmental contour information. [0003] Compared with methods such as ultrasonic waves and depth cameras, laser has the characteristics of high coherence and high directionality, which can greatly improve the measurement accuracy, so it is widely used in distance measuring devices. The laser ranging method has the characteristics of fast measurement speed and long range. At present, many indoor robot systems use laser ranging devices as sensors to realize positioning, construct maps and barriers. [0004] Laser ranging methods...
