If my explanation is not clear, imagine taking a bunch of screenshots of this page. Now we want to stitch all of them together into one big image. All of our screenshots of this page are perfectly flat 2D and don't need any Z rotation. I have similar type image and I'm trying to achieve something like this. The issue is that findHomography() adds tiny bit of Z rotation which I want to get rid of. |
| 2017-04-21 04:09:31 -0600 | asked a question | Removing Z rotation from homography matrix before warpPerspective I'm trying to stitch together Images. I have homography matrix from findHomography() which I then pass to warpPerspective(). My issue is that all of the images are flat 2D ones, meaning they will never need any Z rotation. The findHomography(), however, thinks otherwise. How do I disable Z rotation in homography matrix? |
