A method which reconstructs smooth or concave surface, that the volume intersection method can not reconstruct, is proposed. The method reconstructs depth images from needle maps which are obtained with photometric stereo. In case the needle maps contain depth edges, incorrect depth images are reconstructed. An incorrect depth image is not consistent with silhouettes which are taken from other view points. Based on this fact, our method minimizes two types of energy to reconstruct the depth image: One energy is based on a consistency between depth image and needle map, and the other is based on a consistency between depth image and silhouette. Experimental results which synthesis and real data evaluate the effectiveness of our method.
