At the TTI vanguard conference in Barcelona - Steven Stetz from the University of Washington gave us a glimpse of the photo-viewers of the future. In short he takes multiple 2D images (say from flickr) of a particular locatiuon and "stiches" them together to create a 3D model. Very impressive stuff. The power of the navigation between the images is stunning.
Well worth seeing the video demos on his web site. The part of the video on the Great Wall got my particular attention, gievn that my own charity trek there is onky a few weeks away now.
Quite apart from creating rich "phototourism" experiences I can see many business industrial applications for this, especially around large manufacuring plants, civil engineering etc.
Microsofts's Photosynth work is based on Steven's research. Also well worth a visit.
