Web1.去掉重复线的方法可以参考NMS的思路，搞个阈值去掉相近的线。. 还有霍夫变换的阈值可以调一调。. 2.求直线交点是高中知识点啊...联立方程就能求解....直线方程参数应该是这个函数直接返回的。. 3.更好的方式求中心坐标暂时没想到.....最近脑子有点不好使 ...
WebSep 28, 2024 · Once you have the line segments from Hough you could search them to find the ones likely to be part of the bottom line (ie correct angle and intercept) then remove all black dots along this predicted line rather than just the segments found by hough.
WebOct 26, 2016 · I tend to get very imprecise results with OpenCV's implementation of the Circle Hough Transform, as if the step size of the parameter space search was too big.
