Abstract

A complete description of a three-dimensional shape measurement method with an arbitrarily arranged projection moiré system is presented, including the mathematical derivation of theoretical equations, phase-to-height calibration technique, and experimental result of practical object. The proposed method requires neither a specific system setup configuration nor a manual determination of system geometric parameters, and it yields high measurement resolution and accuracy while allowing the system components to be arbitrarily positioned. A real experiment has been conducted to verify the validity of this method.
