Composite phase-shifting algorithm for 3-d shape compression

Abstract

A method includes acquiring a 3-D geometry through use of a virtual fringe projection system and storing a representation of the 3-D geometry as a RGB color image on a computer readable storage medium A method for storing a representation of a 3-D image includes storing on a computer readable storage medium a 24-bit color image having a red channel, a green channel, and a blue channel. The red channel includes a representation of a sine fringe image. The green channel includes a representation of a cosine fringe image. The blue channel includes a representation of a stair image or other information for use in phase unwrapping. Alternatively, all channels may include representations of fringe patterns.
