there are several research efforts in this direction, most notably from CMU's vision group - "Virtualized reality" - where upto 50 video streams are captured from different positions. Stereo techniques can then be used to build complete 3D surface models, and create a virtual world, which can be freely navigated. The major problem, right now, is doing this in real-time. Last I heard, they recorded the video on 50 different processors and did the reconstruction offline. Here's a link: http://www.cs.cmu.edu/~virtualized-reality/
