Paper Abstract

A method to reliably extract object profiles even with surface discontinuities (that leads to 2nπphase jumps) is proposed. Proposed method uses an amplitude modulated Ronchi grating, which facilitates one to extract phase and unwrap the same with a single image. The modified grating image can be split into two images, one aids in extracting the wrapped phase using Fourier transform profilometry, and the other aids in reliable phase unwrapping. As we only need a grayscale projector that projects amplitude modulated grating, proposed method facilitates one to extract 3D profile without using full video projectors.
