Amazing stuff from Carnegie Mellon University. 3D reconstruction from a single photograph. There's linux and windows software to play with !! I wonder whether this will find it's way into cameratracking software.
Our system automatically constructs simple "pop-up" 3D models, like those one would find in a children's book, out of a single outdoor image. The system labels each region of an outdoor image as ground, vertical, or sky. Line segments fitted to the ground-vertical boundary in the image and an estimate of the horizon's position provide the necessary information to determine where to "cut" and "fold" in the image. The model is then popped up, and the image is texture mapped onto the model. Automatic Photo Pop-up pages at Carnegie Mellon University
