说明：  Hough变换是图像处理中从图像中识别几何形状的基本方法之一，应用很广泛，也有很多改进算法。主要用来从图像中分离出具有某种相同特征的几何形状(如，直线，圆等)
(Hough transform is one of the basic methods for recognizing geometric shapes from images in image processing. It is widely used and has many improved algorithms. Mainly used to separate geometric shapes (such as lines, circles, etc.) with certain features from the image.)
