Abstract: A LIDAR includes an emission module, a beam adjustment module and a receiving module, where the beam adjustment module includes a first scanning apparatus and a second scanning apparatus. The emission module is configured to emit a laser beam. The first scanning apparatus is rotated in a first set direction to drive the laser beam to scan along a first direction, and the second scanning apparatus is rotated in a second set direction to drive the laser beam to scan along a second direction. A receiving beam is formed after the laser beam is reflected in the detection region, and the receiving beam is reflected by the second mirror of the second scanning apparatus and then received by the receiving module. The size of the first scanning apparatus can be reduced.

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.
