问题描述
我想使用 OpenCV for Android 检测椭圆，使用 OpenCV 2.4.1 包中包含的 Tutorial 2-Basic 作为起点.请注意，我的椭圆将是一个完美的 Photoshop 椭圆.
I would like to detect ellipses with OpenCV for Android, using the Tutorial 2-Basic included with OpenCV 2.4.1 package as a starting point. Note that my ellipse would be a perfect-photoshop one.
据我了解，使用HoughCircles"只会找到完美(或左右)的圆圈，因此会忽略椭圆.
From what I understand, using the "HoughCircles" will only find perfect (or so) circles, thus leaving ellipses out.
任何帮助将不胜感激，因为我是 OpenCV 的初学者
Any help would be much appreciated as I am a total beginner at OpenCV
这是我迄今为止尝试过的
This is what I've tried so far
case Sample2NativeCamera.VIEW_MODE_CANNY: (ignore the Canny mode...)
capture.retrieve(mGray, Highgui.CV_CAP_ANDROID_GREY_FRAME);
Imgproc.HoughCircles(mGray, mCircles, Imgproc.CV_HOUGH_GRADIENT, 1, 20);
Log.d("Ellipse Points", " X " + mCircles.get(1,1)[0] + mCircles.get(1, 1)[1]);
break;
如果您认为任何更多信息可能有用，请告诉我.

推荐答案
您的问题的一个可能解决方案类似于此线程 Detection of图片上的硬币(和适合的椭圆) .
One possible solution to your problem is similar to this thread Detection of coins (and fit ellipses) on an image .
你应该看看opencv的函数fitEllipse.
You should take a look a opencv's function fitEllipse.
