A Voxel-Independent Reconstruction Method of Object Shape and Its Reflection Property under Unknown Lighting Condition


In this paper, we present a new approach to reconstruct 3D object shape and reflection property in real space under unknown lighting condition. In our approach, the calculation of reconstruction is done independently at each voxel. Reconstructed reflection property represents both diffuse reflection and specular reflection at each voxel. Based on Torrance-Sparrow reflection model, we propose an improved reflection model suitable to the voxel-independent reconstruction. Our method consists of 3 steps. First we extract surface voxels. Then the surface normal at each surface voxel is calculated. Finally, we estimate reflection property of it. Experimental results show the effectiveness of our method.
