Galvanometer control laser scanning accuracy correction method

The invention provides a galvanometer control laser scanning accuracy correction method. The galvanometer control laser scanning accuracy correction method includes the steps that five transverse lines and five longitudinal lines are drawn in equal proportion through cartographic software, and twenty five feature point area patterns are obtained; the twenty five feature point area patterns are printed on a hard paperboard in the proportion being 1:1; and the standard hard paperboard is arranged on a laser scanning focal plane, feature points are sequentially corrected through correction software, laser spots of laser beams projected to the hard paperboard through a galvanometer coincide with corresponding feature points on a standard hard paperboard, and laser scanning correction is completed. The galvanometer control laser scanning accuracy correction method has the beneficial effects that compared with a traditional correction method, the method that the hard paperboard with twenty five standard feature poi
