Computer scientists create 3D models using millions of 2D images

Researchers have devised a technique that allows a computer to create three-dimensional images of famous landmarks, by combining numerous two-dimensional photos of those landmarks from Internet photo sharing sites such as Flickr. For the Building Rome on a Cloudless Day project, 3 million photos of Rome were accessed online, and used to produce 3D images of all the city’s major landmarks. Utilizing commodity graphics hardware, it took a single PC less than one day to accomplish the task.
