根据园的方程(x-a)×(x-a)+(y-b)×(y-b)=R×R,将参数空间增加到a,b,R三维空间.
常用的hough变换计算量太大,然而随机hough变换虽然计算量相对小点,但是准确率没有前者高.现在使用
一种改进的方法:提取边缘图像,然后边缘跟踪,在边缘曲线上进行hough变换检测圆.-According to Park' s equation (x-a) × (x-a)+ (y-b) × (y-b) = R × R, the parameter space to a, b, R three-dimensional space. Hough transform commonly used in the calculation too, however, although randomized hough transform a relatively small amount of calculation, but not the former high accuracy. now use an improved method: extracting the edge image, and then the edge of track, at the edge curve on the hough transform circle detection.
