中文说明: Hough 变换可以提取图像中的直线。但是提取的直线的精度不高。而很多场合下,我们需要精确的估计直线的参数,这时就需要进行直线拟合。 直线拟合的方法很多,比如一元线性回归就是一种最简单的直线拟合方法。
English Description:
Hough transform can extract the straight line in the image. But the accuracy of the extracted line is not high. In many cases, we need to accurately estimate the parameters of the line, then we need to fit the line.
