Particular Forms of Homography Matrices
Diane Lingrand · 2000
This paper deals with monocular video sequences without calibration to recover a maximum of information on displacement and projection parameters. In this paper, we propose a new way to deal with the huge number of particular cases of homographic relations and validate this approach with some experiments showing that if several models are correct, the model with less parameters gives the best estimation. The experiments presented in this paper show also that even if the motion is approximate, the method is still robust. 1 Introduction Let us consider uncalibrated monocular video sequences to recover a maximum of information on displacement and projection parameters. This work extends previous studies [22, 13, 14] on particular displacement cases, scene geometry and camera analysis. It focuses on the particular forms of fundamental and homographic matrices. Several authors have already been interested in particular cases of projection [2, 6, 11, 12, 19, 16], or displacement [10...
