直接上全部代码,测试代码有更新(把采用ransac的方法加进去了),ransac拟合直线的函数就是fitline_ransac import cv2 as cv import numpy as np import math import time def get_distance_line_and_p_batch(vx, vy, p0, p1_list): """ 求点到直线距离 :param vx: :param vy: :param p0: 线上点 :param...
RANSAC 是一个强大的框架,用于查找符合特定模型的数据点。我们将在此考虑应用 RANSAC 的模型是椭圆的圆锥截面模型。RANSAC 对“异常值”——不符合给定模型的数据点——有很强的抵抗力。为了解释算法本身,让我们考虑在 2D 点的噪声数据集中寻找直线的问题。策略是:从数据集中随机采样点 找出符合这些点的直线方程 找...
RANSAC用在直线拟合上。就是 RepeatNtimes: •Drawspoints uniformly at random •Fit line to thesespoints •Find inliers to this line among the remaining points(i.e., points whose distance from the line is less thant) •If there aredor more inliers, accept the line and refit using all ...
可以使用最小二乘法或RANSAC等算法来拟合直线,OpenCV提供了fitLine函数来实现。 6.可视化:将检测到的车道线在原始图像上进行可视化,可以使用OpenCV的line函数来绘制检测到的直线。 最终,可以采用OpenCV读取视频,进行灰度化处理,然后用canny算子进行边缘检测,分析轮廓,然后进行直线拟合处理,最后对直线添加权重分析,得到...
this line, a simple least squares method for line fitting will in general produce a line with a bad fit to the inliers. The reason is that it is optimally fitted to all points, including the outliers. RANSAC, on the other hand, can produce a model which is only computed ...

matlab学习:最小二乘拟合&基于RANSAC的直线拟合&椭圆拟合 2012-10-13 08:58 −1.最小二乘拟合 最小二乘拟合是一种数学上的近似和优化,利用已知的数据得出一条直线或者曲线,使之在坐标系上与已知数据之间的距离的平方和最小。 2.RANSAC算法 参见王荣先老师的博文 http://www.cnblogs.com/xrwang/archive/2011...
