Dynamic Projection Mapping with Networked Multi-projectors Based on Pixel-parallel Intensity Control

We present a new method of mapping projections onto dynamic scenes by using multiple high-speed projectors. The proposed method controls the intensity in a pixel-parallel manner for each projector. As each projected image is updated in real time with low latency, adaptive shadow removal can be achieved for a projected image even in a complicated dynamic scene. Additionally, our pixel-parallel calculation method allows a distributed system configuration so that the number of projectors can be increased by networked connections for high scalability. We demonstrated seamless mapping onto dynamic scenes at 360 fps by using ten cameras and four projectors.
