Abstract: A method for adjusting swinging of a galvanometer is provided in implementations of the disclosure. The method includes the following operations. Guide a processing laser to a laser processing surface via a first galvanometer, and establish a first correspondence between a reference coordinate system of the laser processing surface and coordinate-ranges of swinging angles of the first galvanometer. Perform region division on the laser processing surface in the reference coordinate system to obtain P calibrating selected-regions of the laser processing surface. Determine coordinate of a swinging angle of the first galvanometer corresponding to one of target points in Q calibrating selected-regions in the P calibrating selected-regions according to the first correspondence, to obtain coordinates of Q swinging angles of the first galvanometer.
