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/216050...
//第二个参数,InputArray类型的circles,经过调用HoughCircles函数后此参数存储了检测到的圆的输出矢量,每个矢量由包含了3个元素的浮点矢量(x, y, radius)表示。 //第三个参数,int类型的method,即使用的检测方法,目前OpenCV中就霍夫梯度法一种可以使用,它的标识符为CV_HOUGH_GRADIENT,在此参数处填这个标识符即可。
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 ...
