Hi, I have a set of aerial images and I run them through Bundler (SfM) which gives me the rotation and translation matrices of aall cameras relative to a random coordinate system.

Hi, I have a set of aerial images and I run them through Bundler (SfM) which gives me the rotation and translation matrices of aall all cameras relative to a random coordinate system.
I want to take two of those images, img0 and img1. The first one I assume is aligned with a reference frame and therefore H0 = eye(3). I want to compute H1, the Homography from img1 to img0 so that I can stitch them into a photo-mosaic,
warpPerspective(img1, img1_warped, H1)
I think this H1 should be given by
H1 = K1*R1*(Mat::eye(3, 3, CV_32F) + ((t1 - t0)*n.t() / t0.at<float>(2)))*R0.t()*K0.inv()
However this is not working very well. What am I missing?
