A homography is a perspective transformation of a plane, that is, a reprojection of a plane from one camera into a different camera view, subject to change in the translation (position) and rotation (orientation) of the camera.

I am trying to set predefined values to homography and then use function warpPerspective that will warp my image. First i used findHomography function and displayed result: H = findHomography(obj,... Every homography is the composition of a finite number of perspectivities. In particular, if the dimension of the implied projective space is at least two, every homography is the composition of a finite number of central collineations. If projective spaces are defined by means of axioms (synthetic geometry), the third part is simply a definition.

Ups nut sourceA great source to learn about Homography (with examples in Python, C++) — Homography Examples using OpenCV; Let me know if you have any suggestions/feedback! ACM VIT.Say I use only one calibrated camera. From this camera, I get images A and B. I know the homography between A and B, computed through OpenCV's findHomography().. I know the pose (rotation matrix R and translation vector t) of image A, and I need the pose of image B.

Camera Calibration and 3D Reconstruction¶. The functions in this section use a so-called pinhole camera model. In this model, a scene view is formed by projecting 3D points into the image plane using a perspective transformation.
