在OpenCV中为python找到用CornerHarris方法标记的角落的坐标 [英] Find the coordinates of the Corners marked with CornerHarris method in OpenCV for python

问题描述

我试图找到HarrisCorner方法在我的图像上标记的所有形状的坐标。

I'm trying to find the coordinates of all the shapes that HarrisCorner method marked on my image.

我设置了它，所以它标记正确的角落并显示正确的结果，但我不知道在哪里找到所有的坐标后说完成。
我需要一个由这个算法标记的所有角落的列表，所以我可以找到他们的区域，重心，形状&尺寸。
另外，我有一个包含在每个形状内的所有像素的列表，所以我很容易匹配坐标与相应的形状。
对不起，如果这是一个绿色问题。我一直在阅读我能找到的一切。谢谢OpenCV专业！

I have it set up so it's marking the correct corners and showing the correct results, but I can't figure out where to find the coordinates after all is said and done. I need a list of all of the corners that are marked by this algorithm so I can find their area, center of gravity, shape, & size. Separately I have a list of all of the pixels contained within each shape, so it would be easy for me to match the coordinates with the corresponding shape. I'm sorry if this is a green question. I've been reading everything I can find. Thank you OpenCV pros!

    im = cv.LoadImage("image.jpg")
    imgray = cv.LoadImage("image.jpg", cv.CV_LOAD_IMAGE_GRAYSCALE)

    cornerMap = cv.CreateMat(im.height, im.width, cv.CV_32FC1)
    cv.CornerHarris(imgray,cornerMap,3)
    for y in range(0,imgray.height):
       for x in range (0, imgray.width):
          harris = cv.Get2D(cornerMap, y, x)
          if harris[0] >10e-06:
              temp = cv.Circle(im, (x,y),2,cv.RGB(115,0,25))

    cv.ShowImage('my window', im)
    cv.SaveImage("newimage3.jpg",im)
    cv.WaitKey()

推荐答案

角落是您的角落测试通过的（x，y）坐标：

The corners are the (x,y) coordinates for which your corner-ness test passes:

if harris[0] > 10e-06
