A Utilização da Técnica de Chromakey para Composição de Cenas em Ambientes de Realidade Aumentada

Antonio Carlos SementilleHeitor Sponton PirolloSílvio Ricardo Rodrigues SanchesIldeberto Aparecido RodelloJosé Remo Ferreira Brega

A classic problem in the construction of Augmented Realitysystems is the registration. The correct alignment between virtualobjects and the real elements is of extreme importance, for thecoherent composition of the resultant scene. Considering thiscontext, this paper describes an approach for the composition ofscenes, in Augmented Reality environments, which makes use ofthe chromakey technique for the extraction of real objects. Afterthis extration, the scene is mounted coherently, with relation tothe depth, in framebuffer of the OpenGL, for posterior rendering.
