我需要检测一个螺旋形弹簧和计数其线圈匝。
我曾尝试如下:
Image<Bgr, Byte> ProcessImage(Image<Bgr, Byte> img)
{
Image<Bgr, Byte> imgClone = new Image<Bgr,byte>( img.Width, img.Height);
imgClone = img.Clone();
Bgr bgrRed = new Bgr(System.Drawing.Color.Red);
#region Algorithm 1
imgClone.PyrUp();
imgClone.PyrDown();
imgClone.PyrUp();
imgClone.PyrDown();
imgClone.PyrUp();
imgClone.PyrDown();
imgClone._EqualizeHist();
imgClone._Dilate(20);
imgClone._EqualizeHist();
imgClone._Erode(10);
imgClone.PyrUp();
imgClone.PyrDown();
imgClone.PyrUp();
imgClone.PyrDown();
imgClone.PyrUp();
imgClone.PyrDown();
imgClone._EqualizeHist();
imgClone._Dilate(20);
imgClone._EqualizeHist();
imgClone._Erode(10);
Image<Gray, Byte> imgCloneGray = new Image<Gray, byte>(imgClone.Width, imgClone.Height);
CvInvoke.cvCvtColor(imgClone, imgCloneGray, Emgu.CV.CvEnum.COLOR_CONVERSION.CV_BGR2GRAY);
imgCloneGray = imgCloneGray.Canny(c_thresh, c_threshLink);//, (int)c_threshSize);
Contour<System.Drawing.Point> pts = imgCloneGray.FindContours(Emgu.CV.CvEnum.CHAIN_APPROX_METHOD.CV_CHAIN_APPROX_SIMPLE, Emgu.CV.CvEnum.RETR_TYPE.CV_RETR_EXTERNAL);
CvInvoke.cvCvtColor(imgCloneGray, imgCloneYcc, Emgu.CV.CvEnum.COLOR_CONVERSION.CV_GRAY2BGR);
if (null != pts)
{
imgClone.Draw(pts, bgrRed, 2);
imgClone.Draw(pts.BoundingRectangle, bgrRed, 2);
}
#endregion
return imgClone;
}
我一些如何能够得到春天,但如何获得计数。 我要找的算法。 我目前不是在寻找速度优化。
这就好比手指算相似。 春天螺旋很薄利用等高得到。 还有什么可以做。 http://www.luna-arts.de/others/misc/HandsNew.zip
