摘要
在工业精密尺寸检测问题中,由于工作的制造精度、破损和锈蚀,使得所获得的目标图像边缘粗糙且带有噪声,造成自动检测困难。因此,精确提取目标边缘特性曲线已成为开发工业自动检测系统中的一个难题。图形轮廓线的自动别是新一代CAD设计系统必不可少的基本功能,通过对图形轮廓线自动识别技术的探讨,得出一种识别算法的图形轮廓自动识别的主要步骤。本算法用V isna l C++语言编写实现,它不需要大量的运算,它是一种适用于任一2D数据图形文件的轮廓线自动识别的新方法——局部坐标判别法。
In the lest of dimensional precision in industry, the edges of object image obtained may be coarse and with noise, due to the precision, disrepairs and corrosion. This causes difficult, in the auto test. So it becomes difficult in the industrial auto test system how to acquire the desired bounolary curve. Auto recognition of the graphic outline is a necessary basic function for the new CAD design system. Through discussing the auto recognition of the graphic outline, an identification arithmetic and the main steps of the auto recognition of the graphic outline is given. This arithmetic is realized by Visual C＋＋ language. Where large amounts of calculation is not. As a new method, local coordinate isapplied in auto recognition of the graphics outline of any 2D data graphit files.
