Augmented reality (AR) is a growing field, with many diverseapplications ranging from TV and film production, to industrialmaintenance, medicine, education, entertainment and games. The centralidea is to add virtual objects into a real scene, either by displayingthem in a see-through head-mounted display, or by superimposing them onan image of the scene captured by a camera. Depending on theapplication, the added objects might be virtual characters in a TV orfilm production, instructions for repairing a car engine, or areconstruction of an archaeological site (see Figure below).
For the effect to be believable, the virtual objects must appearrigidly fixed to the real world, which requires the accuratemeasurement in real-time of the position of the camera or the user'shead. Present technology cannot achieve this without resorting tosystems that require a significant infrastructure in the operatingenvironment, severely restricting the range of possible applications.
The objective of MATRIS is to develop and implement a system fordetermining the position, orientation, and focal length of a camera inreal time, by analysis of the camera images and exploitation ofunobtrusive inertial motion sensors. As the system will not requiremarkers or other special infrastructure in the environment, it will besuitable for applications where existing tracking systems cannot easilybe used, including:
insertionof virtual objects in live broadcast images outside of a dedicated"virtual studio" environment, such as graphics for sport, or virtualobjects in a conventional TV studio
augmented reality applications in the area of development, production, service and maintenance
augmented reality for architecture, design and product presentation
augmented reality for cultural heritage sites and tourism
