The term ''Augmented Reality'' covers a wide range of applications, from the overlay of virtual graphics on a real scene using a head-mounted display for use in areas such as industrial maintenance, through to the insertion of real-time virtual graphics in TV programmes. Fundamental to all these applications is the need to be able to accurately track the motion of the camera, so that the graphics may be rendered so as to appear rigidly locked to the real world. To overcome the limitations of existing tracking systems, the MATRIS project has developed a real-time system for measuring the movement of a camera, which uses image analysis to track naturally occurring features in the scene, and data from an inertial sensor. No additional sensors, special markers, or camera mounts are required. This paper gives an overview of the system, provides the context for the other articles in this journal and presents some results.
