Microsoft's Photosynth creates 3D out of 2D Photos

Photosynth, a project from the collaboration of Microsoft Research and the University of Washington will let you creat a 3D walkthrough from a bunch of Photographs. And with photos abound on the internet, and tags having simplified photo search, you could create a 3D walkthough of anything from a flickr result. Amazing, no? Read more.

Photo Tourism is a system for browsing large collections of photographs in 3D. Our approach takes as input large collections of images from either personal photo collections or Internet photo sharing sites, and automatically computes each photo's viewpoint and a sparse 3D model of the scene. Our photo explorer interface enables the viewer to interactively move about the 3D space by seamlessly transitioning between photographs, based on user control.
