This student project investigates the potential of projector-camera systems as components for future game consoles. The geometry and radiometry of the real environment is automatically scanned, scene elements are identified, clustered and integrated into the game logic. Virtual game figures can then be projected stereoscopically into the real environment to enable an exciting augmented reality game experience. Artefacts that are due to modulation of projected light on the real environment's surfaces are compensated in real-time to achieve a certain level of consistency. Virtual objects can interact with real objects and vice versa. When colliding with virtual objects, for instance, real objects appear to shake through a special stereoscopic effect. A pan-tilt projector-camera unit will allow using large parts of an entire room as playground for spatial augmented reality games.

We present a novel multi-step technique for imperceptible geometry and radiometry calibration of projector-camera systems. Our approach can be used to display geometry and color corrected images on non-optimized surfaces at interactive rates while simultaneously performing a series of invisible structured light projections during runtime. It supports disjoint projector-camera configurations, fast and progressive improvements, as well as real-time correction rates of arbitrary graphical content. The calibration is automatically triggered when mis-registrations between camera, projector and surface are detected. Zollmann, S. and Bimber, O.

Traceable Radiometry Underpinning Terrestrial- and Helio- Studies (TRUTHS) mission offers a novel approach to the provision of key scientific data with unprecedented radiometric accuracy for Earth Observation (EO) and solar studies, which will also establish well-calibrated reference targets/standards to support other EO missions. TRUTHS is a concept designed at NPL, the UK national measurement institute and has wide support in the international science community.
