ABSTRACT:
Systems and methods of multiframe correspondence estimation are described. Light patterns reflected from the scene are captured at one or more capture planes. In one aspect, a sequence of patterns of light symbols that temporally encode two-dimensional position information in a projection plane with unique light symbol sequence codes is projected onto a scene. A correspondence mapping between multipixel regions in the capture plane and corresponding regions in the projection plane is computed based at least in part on correspondence between light symbol sequence codes captured at the capture plane and light symbol sequence codes projected from the projection plane. In another aspect, the patterns consist of a single plane of light that is swept across the scene. Correspondence is determined based at least in part on exploiting the epipolar constraint associated with any pair of cameras.
