介绍基于BMP图像的轮廓跟踪算法和轮廓序列点处理算法，此方法只需扫描图像一次，即可得到图像中所有轮廓信息，具有速度快的优点。分析了Bezier曲线进行拟合及NC代码生成方法。此方法已应用在自行开发的数控雕刻机系统上，并加工出较好样品，具有适用范围广、处理速度快、处理效果好等优点。% Abstract： The paper introduces the algorithm based following the trace of contour for BMP image and processing algorithm for the sequence point of the contour line. The method which scan the image for only one time attains all contour information ,whose virtue is rapid on speed. The method of closing the curve by Bezier curve and making NC code are analysed. The technology has been applied on computer numerical control system by our own,whose virtues are widespread on range, rapid on speed, good on effect.
