这段代码是 OpenCV c++:
lines = cvHoughCircles(frame2, storage, CV_HOUGH_GRADIENT, 1, 50, 300, 60, 10, 600);
for (int i = 0; i < lines.total(); i++) {
//Would like the code to go here
CvPoint2D32f point = new CvPoint2D32f(cvGetSeqElem(lines, i));
cvCircle(src, cvPoint((int)point.x(), (int)point.y()), 3, CvScalar.WHITE, -1, 8, 0);
Point p = new Point((int)point.x(), (int)point.y());
points.add(p);
}
新的 Java Api 中的对应者是什么?我无法得到CvPoint2D32f
,cvGetSeqElem
和CV_AA
。我发现它存在于 JavaCV 但在 OpenCV Java api 中找不到它们。
谢谢

我改变了我的代码,现在我有了:
MatOfPoint3 circles = new MatOfPoint3();
Imgproc.HoughCircles(image, circles, Imgproc.CV_HOUGH_GRADIENT,2, image.rows()/4,200,100,0,0);
for(Point3 circle : circles.toArray()){
Point center = new Point(circle.x, circle.y);
int radius = (int) Math.round(circle.z);
Core.circle(image, center, radius, new Scalar(0,255,0), 6, 8, 0);
}
但是我在for(Point3 circle : circles.toArray())
:
Exception in thread "main" java.lang.UnsupportedOperationException: Mat data type is not compatible: 21

对此有什么想法吗?谢谢

最后编辑问题的解决方案在于
MatOfPoint3 circles = new MatOfPoint3();
一定是
MatOfPoint3f circles = new MatOfPoint3f();
