Title:
LIDAR AND SCANNING CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/045521
Kind Code:
A1
Abstract:
A LiDAR (10, LA0) and a scanning control method therefor. The LiDAR (10, LA0) comprises a transmitting module (11, TX0) and a scanning module (13, SC0). The scanning control method comprises: on the basis of a preset scanning control parameter of a scanning module (13, SC0) and a preset light-emission time sequence control parameter of a transmitting module (11, TX0), controlling the scanning module (13, SC0) to move and controlling the transmitting module (11, TX0) to emit light, so as to form scanning point sequences, with a plurality of scanning point sequences forming, in a scanning field of view, a scanning pattern in which scanning points are uniformly distributed, wherein the preset scanning control parameter and the preset light-emission time sequence control parameter satisfy a matching relationship, such that light-emitting point sequences are arranged corresponding to the poses of the scanning module (13, SC0), so as to form the scanning point sequences. In the solution, two performance parameters including the resolution and ranging distance of the LiDAR (10, LA0) can both be taken into consideration, such that when at least one performance parameter index is improved, the impact on the other performance parameter index can be avoided, and scanning points formed in a scanning field of view are uniformly distributed.
