Abstract

FAST Vision approach C. facets stereo vision) for object surface reconstruction comprises the simultaneous least-squares computation of object surface and object optical density D X,Y) from image grey values. Both functions are represented by finite elements in facets. In this paper investigation on the size ratio of pixels and facets for the optical density function D (X,Y) are presented using two different representations: the bilinear and the bicubic finite element representation. For both a ratio of 2x2 pixels per D-facet comes up to be a reasonable compromise between good approximation and good regularization.
