中文说明：应用背景直线通常对应着重要的边缘信息，直线提取是计算机视觉中一项非常关键重要的技术，因此把直线单独抽取出来研究有重要的意义，其提取方法与一般的边缘检测方法不同。关键技术hough变换是对二值图像进行直线检测的有效方法，其实质是对图像进行坐标变换，将图像空间的点映射到参数空间，使变换的结果便于检测和识别。
English Description：
Application backgroundLinear usually corresponds to an important edge information, the straight line extraction is a very important technology in computer vision, and therefore the linear independently extracted study has important significance. The extraction method and the general method of edge detection.Key TechnologyHough transform line detection method of binary image, the essence of which is the image of coordinate transformation, image space point is mapped into the parameter space, the transform results for detection and recognition.
