Image Presentation System Using a Head-Mounted Projector
Details
In recent years, there have been many studies on Augmented Reality (AR) which overlays some visual information, such as CG images, on the real scene. As a tool for AR technology, this paper proposes an image presentation system in which the visual information is projected from a head-mounted projector onto a portable cubic screen. The cubic screen equipped with several infrared LEDs as invisible markers is captured by a head-mounted camera, and its 3D position and orientation are estimated using a particle filter based algorithm. According to the estimation result, a CG image corresponding to the user's viewpoint is computed and projected onto the screen. This process provides the user with a feeling that he or she is looking at a virtual object in the cubic screen.
