Parallel Tracking and Mapping for Small AR Workspaces (PTAM) via George Klein
Video results for an Augmented Reality tracking system. A computer tracks a camera and works out a map of the environment in realtime, and this can be used to overlay virtual graphics. Presented at the ISMAR 2007 conference.
This video shows extra video results made at ISMAR. All sequences were processed and recorded live on a dual-core laptop.
