CORRECTION METHOD FOR USE IN LASER MARKING AND DEVICE THEREFOR

摘要

A correction method for use in laser marking, comprising: obtaining an image to be marked; determining the fracture zone and non-fracture zone of the image to be marked in the preset coordinate system of a laser marking machine; correcting the non-fracture zone of the image to be marked using a preset correction formula; correcting the fracture zone of the image to be marked using a preset standard correction value and a preset weighting coefficient corresponding to the coordinate position; marking the corrected image to be marked. By means of performing a weighted correction on the marking points within the fracture zone according to the subdivided coordinate positions thereof, the method achieves a distortion correction on the fracture zone, and does not need to measure the deviation values of the marking area with high density and high accuracy.
