A structure from motion inequality
Oliver Knill, Jose Ramirez-Herran
We state an elementary inequality for the structure from motion problem for m cameras and n points. This structure from motion inequality relates space dimension, camera parameter…

Space and camera path reconstruction for omni-directional vision
Oliver Knill, Jose Ramirez-Herran
In this paper, we address the inverse problem of reconstructing a scene as well as the camera motion from the image sequence taken by an omni-directional camera. Our structure from…

On Ullman's theorem in computer vision
Oliver Knill, Jose Ramirez-Herran
Both in the plane and in space, we invert the nonlinear Ullman transformation for 3 points and 3 orthographic cameras. While Ullman's theorem assures a unique reconstruction modulo…
