Abstract

A 2D fringe pattern is presented for projected fringe profilometry in the tele-centric system. Compared with the methods which embeds multiple frequencies in one pattern, the proposed one-shot method is more tolerant to low signal-to-noise ratios and more reliable for surface with large color or reflectance variation.
