1. A method of multiframe correspondence estimation, comprising: projecting onto a scene a sequence of patterns of light symbols that temporally encode two-dimensional position information in a projection plane with unique light symbol sequence codes; capturing at a capture plane light patterns reflected from the scene; and computing a correspondence mapping between multipixel regions in the capture plane and corresponding regions in the projection plane 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.
