On the Problem of Parameter Identification in Perspective Systems and Its Application to Motion Estimation Problems in Computer Vision
E.P. Loucks, Bijoy Kumar Ghosh · Birkhäuser Boston eBooks · 1993
We consider the problem of motion and shape estimation of a moving textured surface with the aid of a monocular camera. We show that the estimation problem reduces to a specific parameter estimation of a perspective dynamical system. In this paper we analyze a planar textured surface undergoing a rigid flow and an affine flow. These two cases have been analysed for perspective and orthographic projection. The main result of this paper is to identify what parameters or function of parameters are identifiable.
