Zusammenfassung:The invention relates to a galvanometer-based laser synchronization control method, a galvanometer-based laser synchronization calibration method, a galvanometer-based laser synchronization calibration device and a laser radar. The laser synchronization control method based on the galvanometer comprises the following steps: acquiring a fast axis feedback signal when the galvanometer scans; acquiring a first phase difference between a fast axis driving signal and the fast axis feedback signal, and acquiring a second phase difference between a laser emission period and the fast axis driving signal; and performing phase setting on the fast axis driving signal according to the first phase difference and the second phase difference, so that the laser emitted at a set point is aligned in a preset direction. According to the scheme provided by the invention, synchronous control of laser emission and galvanometer fast axis motion can be well realized. 本申请涉及一种基于振镜的激光同步控制方法、标定方法、装置和激光雷达。该基于振镜的激光同步控制方法,包括:获取振镜进行扫描时的快轴反馈
