Surface normal vector force driven 3D object reconstruction via Graph-cut

Multi-view 3D surface reconstruction is typically formulated as minimizing an appropriate energy functional, which tends to find the empty set, i.e. an undesirable result, especially when cooperating only with a boundary term. So generally a regional term is employed, which indicates inside or outside of the surface. It is, however, the challenge because inherently there is no straightforward way to assign interior or exterior of the surface since photo-consistency on the surface boundary is the main source of geometric information. In this paper, we address this problem by proposing a surface normal vector force driven regional term which is a data-aware ballooning term and cast it into a Graph-cut framework. In experiments, we verify the superiority of the proposed algorithm on various multiple view data sets.
