摘　　要：研究了图像矢量化的关键技术,并将其应用到数控切绘机自动编程系统中。系统的输入为衣服、鞋帽等样片的扫描图,通过中值滤波、二值化、边缘提取、轮廓跟踪和曲线拟合等处理,实现了样片轮廓信息的矢量化。这种方法的应用扩展了数控切绘机自动编程系统的造型功能,增强了切绘机的适用性。The key technologies of image vectorization were presented, and they were applied in automatic NC programming system successfully. The pattern input is the scanning image of clothes、shoes or caps. After median filter, thresholding, boundary tracking, chain code tracking and polynomial fitting, the origin image is faired into lines and arcs. The application of this method extends the design instrument in automatic programming system of NC-cutter greatly.

关 键 词：数控切绘机 自动编程系统 图像矢量化 曲线拟合
