Paper Abstract

In this research, we propose a new scheme to integrate the two important depth information sources, i.e., shading and stereo, in a single framework. By using the ratio of two photometric stereo images, we first derive a new constraint on the local surface structure so that no albedo information is needed for shape reconstruction. Then, by employing the perspectively projected SFS formulation with a generalized parametric surface model, we establish a unified geometrical framework for the integration of shading and stereo. The depth map is directly recovered by minimizing a cost functional which consists of a weighted sum of shading and stereo error terms. Simulation results are given to show the performance of our new robust algorithm.
