Projection Mapping in the Light: A Preliminary Attempt to Substitute Projectors for Room Lights

Projection mapping (PM) in a bright room creates the problem of reducing the contrast of the projected texture because ambient lighting elevates the black level of the projection target. In this paper, we developed a pseudo-ambient lighting technique that turns off the original ambient lighting and reproduces its illumination from the projectors on surfaces other than the target. We confirmed that the proposed technique could reproduce a bright room while suppressing the contrast reduction of the projected texture on the target, which helped to improve the viewing experience.
