利用霍夫变换的方法对图像中的线段进行检测，并将检测出的线段在图像上显示出来-The method of use of the Hough transform to detect the segment in the image, and the detected lines on the image displayed

使用opencv2写的，利用概率霍夫变换检测直线，并检测带有端点的线段。-Use opencv2 written using probabilistic Hough transform to detect straight line, and the line segment with endpoint detection.
