Indeed it has, photosynth - I blogged about it before, http://alicious.com/making-3d-models-from-photos/, http://photosynth.net/preview/view/6de2eb38-4e7e-424b-94a3-9... - which came from Microsoft Research. It looks like this is "just" the video version of what they were doing before with photosynth walkthroughs. Very impressive.
