Abstract:
We describe a new 3D scanning system which exploits the depth discontinuity information captured by the multi-flash camera proposed by [Raskar et al. 2004]. In contrast to existing differential and global shape-from-silhouette algorithms, our method can re-construct the position and orientation of points located deep inside concavities. Points which do not produce an observable depth dis- continuity, however, cannot be reconstructed. We apply Sibley’s method for fitting an implicit surface to fill the resulting sampling gaps [Crispell et al. 2006]. Extending this prior work, we model the appearance of each surface point by fitting a Phong reflectance model to the BRDF samples using the visibility information provided by the implicit surface.
