Three dimensional shape measurement with an arbitrarily arranged projection moire system.
A complete description of a three dimensional shape measurement method with an arbitrarily arranged projection moire 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.
