Description

This paper proposes a novel radiometric compensation technique for cooperative projection system based-on distributed optimization. To achieve high scalability and robustness, we assume cooperative projection environments such that (1) each projector does not have any information about other projectors as well as target images, (2) the camera does not have any information about the projectors either, while having the target images, and (3) only a broadcast communication from the camera to the projectors is allowed to suppress the data transfer bandwidth. The effectiveness of the proposed method is guaranteed theoretically, and also demonstrated through both simulation and real projection experiments.
