A Fast Correction Algorithm for Laser Marking Based on SOPC Technology

In this paper, a fast correction algorithm is proposed for laser marking based on SOPC(System On Programmable Chip) system. The principle of figure distortion and correction algorithm for laser marking is analyzed in detail while correction algorithm is implemented by SOPC. By taking advantage of SOPC system which supports the design of software and hardware in coordination, the embedded processor has finished the man-machine interface task of low operation quantity, a large amount of operation is realized by the FPGA hardware, thus has improved the processing speeds of correction algorithm greatly. Comparing the experiment result of laser marking which has been corrected or not, obviously, the former is better than the latter.
