Abstract

The invention relates to a laser filling method and device for a multilayer contour pattern based on contour lines, computer equipment and a storage medium. The method comprises the following steps: performing outer contour inner offset operation on a to-be-filled pattern according to an equidistant offset algorithm to obtain a contour offset pattern; performing grid method environment modeling on the contour offset pattern to obtain a preprocessed grid pattern; performing inner and outer contour discrimination on the grid pattern to obtain a to-be-filled grid; for the to-be-filled grid, constructing a shortest path problem set; and solving the shortest path problem set by using an A* algorithm to obtain an optimal filling path of the to-be-filled grid. By adopting the method, the laser filling efficiency of the pattern can be improved.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a method, device, computer equipment and storage medium for laser filling of contour-based multi-layer contour patterns. Background technique [0002] In recent years, with the improvement of laser performance and reliability, coupled with the rapid development of computer technology and the advancement of optical devices, laser marking technology has developed very rapidly. With the development of computer and electronic technology, at present, laser marking technology and The combination of computer technology can modify the content of the label in the computer, and then it is widely used in the field of pattern filling. [0003] However, when the current laser filling technology is combined with computer technology for pattern filling, there are problems such as low efficiency, low accuracy, and waste of laser energy resources. Contents of the invention [0004] Bas...
