Abstract

A system of coordinated projectors and cameras enables the creation of projected light displays that are robust to environmental disturbances. This paper describes approaches for tackling both geometric and photometric aspects of the problem: (1) the projected image remains stable even when the system components (projector, camera or screen) are moved; (2) the display automatically removes shadows caused by users moving between a projector and the screen, while simultaneously suppressing projected light on the user. The former can be accomplished without knowing the positions of the system components. The latter can be achieved without direct observation of the occluder. We demonstrate that the system responds quickly to environmental disturbances and achieves low steady-state errors.
