Sobre algunos problemas reales en visión por ordenador que conducen a sistemas de ecuaciones algebraicos

Abstract

In this paper we present some real problems which appear in computer vision which yields to nonlinear system of algebraic equations. We study the problem of camera calibration. Roughly speaking camera calibration consists in looking at the camera position in the 3- D world using as information the projection of a 3- D Scene in a 2-D plane (the photogram). The problem is quite different when we use a single view or several views (stereo vision) of the 3-D scene. We will show in this paper how these problems yields to nonlinear algebraic system of equations.
