The Self-Equalizing De Bruijn Sequence for 3D Profilometry

Tomislav Petković, Tomislav Pribanić and Matea Đonlić

Abstract

Using color in 3D profilometry usually requires a tedious color calibration to mitigate the undesired effects of ambient lighting, object albedo, non-equal channel gains, and channel cross-talk. We propose a novel De Bruijn sequence for multi-channel structured light that removes the need for color calibration of a camera-projector pair. The proposed sequence has the following desirable properties: (1) it enables the extraction of ambient lighting, (2) it enables the cancellation of object albedo, and (3) it enables the equalization of channel gains.
