Obtaining 3-D shape from Silhouette Informations Interpolated by Photometric Stereo

The idea of photometric stereo is to serially vary the direction of incident illumination on the state of the holded view point, but it can locally reconstruct only the front surface to a view point. However the silhouette informations obtained by plural viewing directions provide the entire 3D structure of an object surface, but the 3D information of the region whose edge is unexposed to the viewing direction cannot be obtained. Therefore the two methods make up the demerits each other. In this paper, the possibility of complete three dimensional shape reconstruction was investigated using photometric stereo and silhouette informations. For the entire 3D reconstruction, a chicken bone is used as an experimental object and the reconstructed result is presented and discussed. the other hand, the stereo pair matching by two camera is not a completed method because its running cost and the unstable matching algorithm. The photometric stereo method [6][7][8]can offer the continuous depth ...
