WebJul 26, 2024 · Briefly, the homography is a 3x3 matrix that can be used in many applications such as camera pose estimation, perspective correction, and image stitching. The Homography is a 2D transformation. It maps points from one plane (image) to another. Let’s see how we get it. Estimating the Homography WebApr 16, 2024 · For example, $\mathbf x_i^u=\mathtt H\mathbf x_i^c$ doesn’t literally mean that the homogeneous coordinate vector obtained by multiplying $\mathbf x_i^c$ by $\mathtt H$ is identical to $\mathbf x_i^u$ —for a general homography, the last coordinate of this product won’t usually be equal to $1$ —but that they are members of the same ...
