3D surface reconstruction is an unsolved and important task in computer vision. It aims at restoring three-dimensional features from two-dimensional information and constructing the geometrical model of objects. This thesis focuses on algorithms of the three-dimensional surface reconstruction from silhouette information of objects, designs and develops a multi-view real-time 3D reconstruction system.In this thesis, multiple

In recent years, 3D reconstruction based on image sequences becomes an very important problem in the filed of computer vision and virtual reality. The concept of Visual Hull is defined as the max volume calculated from the silhouette information of the image sequence. The recovery results of the traditional volumetric approaches can’t obtain smooth surface,
