摘　　要：为了满足激光打标系统不同的精度要求,通过分析PLT文件格式,以Visual C++作为软件开发平台,准确解析了文件中的矢量图形,提取到原始打标路径。在传统的直线插补方法基础上进行算法改进,对矢量图形中的曲线作直线段逼近优化,进行了理论分析和实验验证。结果表明,通过设置适当的步长,可很好地解决激光打标系统中提取打标路径的问题。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.
