Abstract

The invention discloses a laser radar control method and device, electronic equipment and a storage medium, and the method comprises the steps: carrying out the optical signal detection of at least one receiving unit of a laser radar in response to the condition that a scanning device is in a flyback mode, and obtaining a detection result of the at least one receiving unit; determining optimized working parameters for the laser radar in response to the detection result; and performing working parameter configuration on the laser radar based on the optimized working parameters. According to the invention, ambient light sensing is carried out in the flyback mode, and the working parameters of the laser radar are further optimized according to the ambient light sensing result, so that the point cloud data of the scanning area in the scanning mode is clearer, and the detection effect of the laser radar is more accurate.

Description

technical field [0001] The embodiments of the present application relate to lidar technology, and in particular, to a lidar control method and device, electronic equipment, and a storage medium. Background technique [0002] In laser radar, using the deflection of the galvanometer to realize the three-dimensional scanning of the laser in space is one of the main scanning methods. Wherein, the vibrating mirror includes a mechanical vibrating mirror, a microelectromechanical system (Microelectro Mechanical Systems, MEMS) micro vibrating mirror, and the like. Galvanometer scanning presents a closed scanning pattern in space and repeats the scanning periodically. The most common type of scanning graphics is row-column raster, and the obtained point cloud effect is intuitive and easy to use. The raster scanning pattern of the galvanometer can be divided into two parts: the normal scanning area and the retrace area. The retrace area is used to return the deflection position of t...
