A simpler and faster technique for depth estimation, based on phase
measurements of disparity, is presented. The technique provides direct
evaluations of phase differences, avoids explicit calculations of single
phases and the attendant problem of phase wrapping, and is suitable for
efficient software and hardware implementations.
