这个程序可以识别图像中的线段或者直线，算法采用哈夫变换，将直线变换为另一个坐标系中的点，进而完成识别。-this procedure can identify the image or straight line segments, Hough transform algorithm. Linear transformation of coordinate system to another's point, thus completing the identification.

用matlab编的霍夫曼方法检测一些线段与圆弧，效果很好，

:为了提高机械手姿态识别的精度,提出了区域边缘线段立体匹配算法-: In order to improve the accuracy of robot posture recognition, line edge of the region proposed stereo matching algorithm
