Abstract: The present application discloses a method and a device for controlling a micro galvanometer of a solid-state LiDAR, and a solid-state LiDAR. The method includes acquiring a vertical angle range of a field of view scanned by the solid-state LiDAR, determining a first vertical angle of the field of view and a second vertical angle of the field of view corresponding to a preset ROI region of the solid-state LiDAR, reducing a slow axis scanning speed of the micro galvanometer to a first preset speed when it is monitored that the micro galvanometer scans the first vertical angle of the field of view, and adjusting the slow axis scanning speed of the micro galvanometer to a second preset speed when it is monitored that the micro galvanometer scans the second vertical angle of the field of view.

Abstract: This application relates to a galvanometer-based laser synchronization controlling method, calibration method and apparatus, and a LiDAR. The galvanometer-based laser synchronization controlling method includes obtaining a fast-axis feedback signal when a galvanometer scans; obtaining a first phase difference between a fast-axis drive signal and the fast-axis feedback signal and obtaining a second phase difference between an emission period of a laser beam and the fast-axis drive signal; and setting a phase for the fast-axis drive signal based on the first phase difference and the second phase difference.

Abstract: A LiDAR detection method, apparatus, and a LiDAR are provided. The LiDAR detection method includes: obtaining ambient information of the LiDAR; determining a detection mode of the LiDAR based on the ambient information; determining a target detection region of the LiDAR based on the detection mode; determining a working parameter of the LiDAR based on the target detection region; and running, by the LiDAR, the working parameter to perform regional detection.
