Abstract: This application is applicable to the technical field of LiDAR and provides a LiDAR controlling method and apparatus, a terminal device, and a computer-readable storage medium. The method includes: controlling a LiDAR to move by a preset stepping in a scanning direction after the LiDAR completes the task of emitting a detection laser beam via a current emission channel, and emitting the detection laser beam via a next emission channel until all emission channels complete the task of emitting the detection laser beam, where the preset stepping is smaller than a divergence angle of a scanning light spot of the current emission channel; filtering echo data received by the current emission channel, and obtaining the scanning result of the current emission channel. Therefore, the scanning light spots between the adjacent emission channels overlap.

Abstract: The present application discloses a LiDAR, which includes a base including a bearing surface, an adjusting structure located on the bearing surface, and a laser transceiving module including a plurality of laser transceiving devices. A galvanometer module of the LiDAR is fixed on the bearing surface. Each laser transceiving device is fixed on the adjusting structure, respectively. Each laser transceiving device is able to generate an outgoing laser emitted to the galvanometer module, respectively. The adjusting structure is configured so that each of the laser transceiving devices has a corresponding distance from the bearing surface, and therefore, the outgoing lasers generated by each of the laser transceiving devices form a preset laser detection field of view outside the LiDAR.
