PDF: A projection-based mixed-reality display for exterior and interior of a building diorama

Abstract

This paper proposes an interactive display system that displays both of the exterior and interior construction of a building diorama by using a projection-based Mixed-Reality (MR) technique, which is useful for understanding the complex construction and the spatial relationships between outside and inside. The users can hold and move the diorama model using their hands/body motion, so that they can observe the model from their favorite viewpoint. Our system obtains both of the user’s information (the viewpoint and the gesture) and the diorama model’s information (the pose) in 3D space by using two RGB-D cameras. The CG image corresponding to the user’s viewpoint, gesture and the pose of the diorama is rendered by Dual Rendering algorithm in real time. As the result, the generated CG image is projected onto the diorama to realize MR display. We confirm the effectiveness of our proposed method by developing a pilot system.
