Paper Abstract

Active image processing full field methods for 3D contactless profilometry are amongst the current methods of choice for obtaining point clouds from object surfaces. The fringe projection system plays a decisive role on the entire process, significantly impacting both quality and reliability of the final measurements. Moreover, most every phase measurement profilometer can only be used under laboratory controlled lighting environments. This note describes the ongoing LOME project for a coherent fringe projection system which will enable outdoor measurements by selectively band pass filtering the projected wavelength.
