Implementing high resolution structured light by exploiting projector blur

This paper presents a novel variant of structured lighting which exploits the inherent blur in the projector system to overcome the discrepancy in resolution between typical Digital SLR cameras and typical projector systems. More specifically, the scheme estimates the coordinates of the projection of each illuminated scene point in the projector frame with subpixel precision and this additional level of accuracy helps to improve the quality of the resulting 3D reconstructions.
