初学C#的OpenCVsharp，霍夫圆变换时圆心如何定义

Question

VectorOfVec3f circles = new VectorOfVec3f();

        //Mat element = new Mat(, Size(13, 13));
        //Cv2.ImShow("Demo", source);
        //element = new Mat();
        //element=
        Cv2.HoughCircles(tempImage, HoughMethods.Gradient, 1.5, 50, 100, 100, 0, 0);
        for (int i = 0; i < circles.Size; i++)
        {

Point center = new Point((int)Math.Round(circles()), (int)Math.Round(circles(i,0))); //定义圆心

int radius = (int)Math.Round(circles.radius);

                            加黑一段的代码不知道这么写才对，求大神解惑，或者有没有opencvsharp的相关学习资料提供也相当感谢。

Answer 1

1. CircleSegment[] circles = Cv2.HoughCircles(tempImage, HoughMethods.Gradient, 1.5, 50, 100, 100, 0, 0);
2. for (int i = 0; i < circles.Length; i++)
3. {
4. //绘制圆心
   
5. Cv2.Circle(dstImage, Convert.ToInt32(circles[i].Center.X), Convert.ToInt32(circles[i].Center.Y), 3, new Scalar(0, 255, 0), -1, LineTypes.Link8, 0);
6. //绘制圆轮廓
   
7. Cv2.Circle(dstImage, Convert.ToInt32(circles[i].Center.X), Convert.ToInt32(circles[i].Center.Y), Convert.ToInt32(circles[i].Radius), new Scalar(155, 50, 255), 3, LineTypes.Link8, 0);
8. }
