Abstract

In this paper, we compare three structured lighting techniques (Gray Code, Gray Code Shift and Stripe Boundary) using mono or stereo camera systems to assess 3D reconstruction for human faces. The calibration technique specific to each system is described. The different algorithms were assessed quantitatively and qualitatively with respect to benchmark data obtained from a high precision 3D scanner. We demonstrate that although a mono camera system coupled to a LCD projector runs faster and at lower cost, the stereo camera system aided by structure lighting generates more accurate results.
