Title:
LIDAR AND DETECTION METHOD THEREOF, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/197570
Kind Code:
A1
Abstract:
Provided are LIDAR and a detection method thereof, and a computer-readable storage medium. The LIDAR comprises a plurality of lasers and a plurality of detectors to form a plurality of channels. The detection method comprises: for all channels, executing detection in groups, wherein the detection comprises: lasers emitting optical signals, and detectors receiving echo signals reflected by an obstacle and obtaining detection information of the obstacle according to the echo signals, each group of lasers emitting light in parallel, and single detection for each channel comprising first sub-detection and second sub-detection; and according to the echo signals of the first sub-detection, correspondingly adjusting light emission strategies, in the second sub-direction and/or first sub-detection of a subsequent round, of the lasers of the channels which emit light in parallel. Therefore, the crosstalk between channels which emit light in parallel can be reduced, thereby improving the detection quality.
