Analysis of Two Errors in Grating Projection Profilometry
A new conceptimage point displacement (IPD) is presented, on which the principles and key tasks in light pattern projection profilometry are re-interpreted and evaluated. Two non-negligible error sources from phase to IPD and from IPD to height are analyzed in detail. Some compensation approaches are proposed and verified by numerical simulation and experiments.
