摘要： Embodiments of this application disclose an opto-mechanical system, where the opto-mechanical system includes a light emission assembly, a light receiving assembly and a light scanning assembly, and the light scanning assembly includes a first light scanning element and a second light scanning element; and along a first linear direction, one of the light emission assembly and the light receiving assembly is on a side of the first light scanning element that is away from the second light scanning element, and the other one of the light emission assembly and the light receiving assembly is on a side of the second light scanning element that is away from the first light scanning element. In this embodiment of this application, not only transmission paths of an emission light signal and an echo light signal can be extended so that a light divergence angle is reduced and ranging performance of the opto-mechanical system is improved, but also the light emission assembly and the light receiving assembly can be separated in space, thereby facilitating heat dissipation of the light emission assembly and the light receiving assembly. With the opto-mechanical system in this embodiment of this application, not only long ranging and high resolution is implemented, but also a pass rate of the opto-mechanical system in an 85°C test as per a vehicle standard can be improved, thereby improving product yield.

摘要： 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 LiDAR controlling 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 a detection laser beam via the next emission channel until all emission channels complete the tasks of emitting detection laser beams, the preset stepping being smaller than a divergence angle of a scanning light spot of the current emission channel; filtering echo data received by the current receiving channel according to the echo data received by adjacent receiving channels, obtaining the scanning result of the current receiving channel, and setting the stepping of the movement of the LiDAR to be smaller than the divergence angle of the scanning light spot of the respective emission channels. Therefore, the scanning light spots between the adjacent emission channels are overlapped, thereby improving the correlation between the adjacent emission channels, and improving the ability of the LiDAR to detect a small target object. Stepping may also be set according to the detection requirement of different scanning regions. For different detection fields of view in a central target detection region, for example, the overlapping rates of the corresponding light spots may be different while the overlapping rate of the light spots is designed to be smaller in the edge regions.
