In the previous section, we learned that if a homography between two images is known, we can warp one image onto the other. However, there was one big caveat. The images had to contain a plane ( the top of a book ), and only the planar part was aligned properly. It turns out that if you take a picture of … Meer weergeven Consider two images of a plane (top of the book) shown in Figure 1. The red dot represents the same physical point in the two images. … Meer weergeven The above equation is true for ALL sets of corresponding points as long as they lie on the same plane in the real world. In other words you can apply the homography to the first image … Meer weergeven The most interesting application of Homography is undoubtedly making panoramas ( a.k.a image mosaicing and image stitching ). Panoramas will be the subject of a later post. Let us see some other … Meer weergeven To calculate a homography between two images, you need to know at least 4 point correspondences between the two images. If you have more than 4 corresponding points, it is even better. OpenCV will … Meer weergeven
