ABSTRACT:
In one aspect, a first sequence of patterns of light symbols that spatio-temporally encode two-dimensional position information in a first projection plane is projected onto a scene. A second sequence of patterns of light symbols that spatio-temporally encode two-dimensional position information in a second projection plane is projected onto the scene. Light patterns corresponding to the first and second sequences of patterns of light symbols reflected from the scene are captured at a capture plane. Captured light symbol sequence codes are determined from the captured light patterns. A correspondence mapping of the first projector plane and the second projector plane with respect to a reference coordinate system is generated based at least in part on correspondence between the captured light symbol sequence codes and the first and second sequences of light symbol patterns.
