Homography labview
In the field of computer vision, any two images of the same planar surface in space are related by a homography (assuming a pinhole camera model). This has many practical applications, such as image rectification, image registration, or camera motion—rotation and translation—between two images. Once camera resectioning has been done from an estimated homography matrix, this inform… Web27 jan. 2016 · And then solve for the homography coefficients and auxiliary variables at the same time by using a nonlinear optimization formulation. In your case, you have N=3 point correspondences per triangle. I have …
