Minimization of image quality degradation in multi-projection mapping

A major problem on projection-based mixed reality, or projection mapping, is that high spatial frequency components of a projection image are degraded by defocus and resampling. This paper proposes a novel method to minimize the image quality degradation of the projected image in multi-projector environment. In the proposed method, it estimate the projected results from the geometric relationship of the projectors and the projection surface, and select the optimal projector for each point of the projection surface.
