WHEN SHOULD THE NON LINEAR CAMERA CALIBRATION BE CONSIDERED?

Abstract

In 3D modelling reconstruction of points, lines, planes or conics are done in the virtual 3D space. Their situations in the 3D virtual scene are defined by the situation of the recognized features in one or several images. Estimation of a parameter vector which models the object is carried out starting with recognized features in the image. Since positions of recognized features in the image are contaminated with noise the solution for the parameter vector is not exact. In order to obtain “the best” solution, optimization algorithms which reduce a residual error are used. They can be classified into linear and non linear ones.The aim of this paper is to determine the quality of estimated parameters if no linear estimation process is utilized. It is shown that in some cases non linear optimization algorithms diverges and worst parameters are computed using non linear methods. In order to obtain experimental results, camera parameters have been estimated under different conditions.
