We recently developed a technique that allows to digitalize 3D objects using a Time-of-Flight camera. One has to move the camera simply around the object. Then the scans are automatically aggregated and fused into a single 3D model. Additionally we use a technique called superresolution to enhance the quality of the model.
This was joint work with Yan Cui, Derek Chan, Sebastian Thrun and Christian Theobalt. See http://ai.stanford.edu/~schuon/ for details.
