Title:
LASER RADAR ATTITUDE CALIBRATION METHOD AND RELATED APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/004792
Kind Code:
A1
Abstract:
A laser radar attitude calibration method and apparatus, a computer storage medium, and an electronic device. The method comprises: obtaining position information of a first calibration object and position information of a second calibration object which are detected by a laser radar to be calibrated (S401); when the position information of the first calibration object and the position information of the second calibration object do not satisfy a preset convergence condition, adjusting the attitude of said laser radar until the position information of the first calibration object and the position information of the second calibration object satisfy the preset convergence condition (S402); and completing the attitude calibration of said laser radar, and storing a current attitude of the laser radar (S403). Attitude parameters of the laser radar are adjusted by using the detected position information of the calibration objects, such that a measurement error possibly caused when laser radar hardware is assembled can be reduced.
