Abstract

In order to meet the accuracy of a laser marking system,after analyzing the PLT file's format,the vector graphics in the PLT file was correctly parsed based on the Visual C++ development platform and the original marking path was extracted.Traditional linear interpolation algorithm was improved because the curves in the vector graphics were approximated to straight lines.Analytical and experimental results show that the algorithm can well resolve the problem how to achieve the marking path by setting an appropriate step length.
