Abstract

The invention provides a regional scanning large-format galvanometer correction system based on an A3 format scanner, and the system comprises the steps: marking a circular array file according to the size of a to-be-corrected format, designing 17 rows and 17 columns of marked circular array files, and marking mark points on a first correction target A and a first correction target B through a to-be-corrected galvanometer; the maximum width is scanned through a two-dimensional scanner, the correction target A and the correction target B are the same galvanometer laser processing equipment, and actual coordinates of all points of the target A and the target B are obtained through an image recognition algorithm; finally, a correction file of the galvanometer is generated through the actual coordinates of 17 * 17 to complete correction, rapid multi-point correction of the galvanometer laser processing equipment with the breadth of 300 mm or above is achieved, manual measurement of coordinates of multiple points as before is not needed, errors and time waste caused by manual measurement are avoided, and the accuracy of the measurement is improved. And data in the whole process can be backed up and recorded through the server.

Description

technical field [0001] The invention relates to the field of scanning large-format galvanometer correction systems, in particular to a sub-area scanning large-format galvanometer correction system based on an A3 format scanner. Background technique [0002] In the field of laser processing, galvanometers are widely used for scanning and marking, but due to the installation of galvanometers and other reasons, the processed images in the scanning area will have various "pincushion distortion", "barrel distortion", "composite distortion" and so on; In order to improve and eliminate this kind of distortion, and make the coordinates of the input laser marking consistent with the coordinates scanned by the actual galvanometer, it is necessary to correct the galvanometer for the laser scanning processing equipment installed with the galvanometer system. For 300mm *300mm galvanometer scanning area or larger galvanometer scanning area especially requires a faster and more accurate ge...
