C# cv2.findhomography

Web为此,我们可以使用calib3d模块中的一个函数,即cv.findHomography()。如果我们从这两幅图像中传递一组点,它就会找到那个物体的透视变换。然后我们可以使用cv.perspective tivetransform()来查找对象。它至少需要四个正确的点来找到转换。 homographyMatrix = OpenCvSharp.Cv2.FindHomography(originalPicturePoints, targetPicturePoints); and then to get any point on the target picture from the original picture: targetPoint = OpenCvSharp.Cv2.PerspectiveTransform(orignalPoint, homographyMatrix);
