A flexible 3D modeling system based on combining shape-from-silhouette with light-sectioning algorithm

In this paper we present a flexible modeling system for obtaining the texture-mapped 3D geometric model. The modeling system uses an algorithm combining shape-from-silhouette with light-sectioning. In the algorithm, at first, a rough shape model is obtained by shape-from-silhouette method almost automatically. Next, concavities and complex parts on the object surface are obtained by light-sectioning method with manual scanning. For applying light-sectioning method to volume data, we propose volumetric light-sectioning algorithm. Then our modeling system can realize easy and accurate generation of 3D geometric model.
