Object modeling using space carving

We consider the problem of computing the 3D shape of an unknown, arbitrary-shaped object. Starting with an initial surface, larger than the scene, we refine it using the object´s projections taken at known but arbitrarily distributed viewpoints. These projections are used independently in a recursive manner. Thus, using more projections improves the reconstruction with a slight increase in the computation time. The technique generates an approximate voxelized representation of the object. We describe the proposed technique and outline the algorithm. Rendered images of voxel spaces recovered from synthetic and real observation images are shown.
