We developed a color Ronchi pattern, a new form of fringe pattern, that can eectively used in fringe projectionprofilometry. The pattern is formed such that color channels red, green and blue are in separate spatial domains.From a single-shot image of the structured pattern, we are able to reconstruct the surface profile of a distortedpaint canvas using both Fourier transform profilometry (FTP) and phase shifting profilometry (PSP). Fromthe three surface reconstructions obtained using FTP, tiny artifacts in the form of ripples are observed. Theseartifacts are significantly reduced when the surface measurements in FTP are averaged. Experimental resultshave shown that both FTP and PSP successfully reconstructed the profile of a distorted paint canvas with ameasurement dierence between 10.00% to 15.00% from the actual displacement.
