如下图,可以判定出平面上的点共构成了两条直线,即检测出两条直线。 OpenCV的算法中内部实际维护的是一个二维数组,当出现相同的(r,theta)则acc[r][theta]自增一,最后我们通过acc[r][theta]阈值的大小来判断极坐标下的该点对应的是否是一条直线 上面参考:http://blog.163.com/yuyang_tech/blog/static/

The OpenCV find contour method is essentially useful as it provides for a pre-defined function that can be called without implementation of an entire code and can be modified using the various parameters. It is essentially helpful in terms of analysing the shape of the image provided, in the ...
1.通过使用opencv获得不同物体的轮廓,以及轮廓所对应的特征,比如说面积、周长、质心、边界框等等。 2.学习一些与轮廓提取有关的函数。 提示:不同版本的python与opencv库可能在函数使用上有少许不同,在使用过程中如果发现不同之处,请到官网查询API: 目录 开始 轮廓特征 Moments图像的矩 图像重心 轮廓面积 轮廓周长...
