Title:
LASER RADAR SCANNING METHOD, CONTROL DEVICE AND LASER RADAR
Document Type and Number:
WIPO Patent Application WO/2023/134748
Kind Code:
A1
Abstract:
A laser radar scanning method, a control device and a laser radar. The laser radar scanning method comprises: performing rotary scanning, at preset initial scanning precision, on an environment where a laser radar is located, so as to obtain scanning data (S100); preprocessing the scanning data in a preset scanning period, so as to determine the degree of change of the environment corresponding to each scanning angle (S200); and according to the degree of change of the environment, adjusting, in real time, the scanning precision at the scanning angle corresponding to the environment (S300). By means of the method, the scanning frequency and the sampling rate can be adaptively adjusted according to a change condition of a target area environment, such that a laser radar can keep relatively high scanning precision in various types of complex environments.
