“System for Displaying Digital Contents on Real Object with Uncalibrated Camera and Video Projector”

In this paper, we propose a system for displaying digital contents onto a white real object with an arbitrary shaped surface. This system consists of the uncalibrated camera and projector. We regard the object surface as many small rectangular regions. By calculating homographies between each image planar suface and a devided rectangular region, the projector renders the image which is projected onto the object surface without distortion. The process is performed by using only 2D images in this system, so a user does not need any equipment or special knowledge for 3D measurement of the object surface. In the experiment, we demonstrate that the digital document can be displayed on the surface of a notebook as if it was printed on a real paper surface of the book.
