Abstract: Disclosed a laser marking machine, method, equipment and system. The method comprises steps of: the control main board receiving coordinate and gray scale value of the target image pixel dot; calculating output power of the target image pixel dot by using the gray scale value; and controlling the laser device to use corresponding output power according to displacement of the galvanometer, and outputting laser specific to each target image pixel dot. By adjusting the output power of target image pixel dot (marking point), a separate pixel dot may reflect the change of gray scale value, so as to represent the image gray scale value. The coordinate of each pixel dot in the gray scale image may be calculated according to the predetermined resolution, such that, the coordinate of pixel dot is no longer adjusted, ensuring the DPI and the resolution of the gray scale image.
