Abstract
A method is provided of parallel gathering of structured light patterns in multi-projector systems, comprising sequentially projecting images from each of a plurality of projectors on a surface; capturing the sequentially projected images on the surface via at least one sensing device; creating one or more sensing device/projector masks for limiting the images projected by each of the plurality of projectors to portions that do not conflict with images projected by other ones of the plurality of projectors; using the one or more projector masks to create a graph of projectors whose projections conflict; and creating from the graph a plurality of gather groups wherein projectors within a group do not conflict with each other for simultaneously gathering structured light patterns from projectors in each of the gather groups.
