Combining Structure from Motion and Photometric Stereo: A Piecewise Formulation

Abstract

This paper introduces a novel piecewise formulation for Photometric Stereo on static scenes exploiting a set of multiple view constraints on the surface. Such constraints will help to recover geometrical properties of the object and to eliminate the global bas-relief ambiguity. On the other hand, the proposed piecewise formulation will help to model more complex photometric properties of the surfaces using local lighting models. The experimental results show performance of the proposed method against 3D ground truth.
