Recently, multi-gray laser mark is one of the most interesting fields in laser mark. But, the software used in multi-gray laser mark can′t produce living, well-bedded, orthoscopic image. In this paper, based on multi-gray laser mark and 5×5 evenly distributed template, the gray relationship of adjacent pixels is considered. Except for marginal pixels, differential operation has been used to every pixels across the window of the size of 3×3 pixels, then texture characteristics are discriminated locally. Based on the local texture in images, corresponding templates are selected. Furthermore, the distortion for dual galvanometer scanning is corrected with the method of Lagrange second-degree parabola interpolation, where the value of distortion in the direction of x- and y-axes are 80, 90, respectively. The aesthetic appearance of marked images is improved greatly removing the effect of trace of matchboard and distortion of dual galvanometer scanning.
