Abstract:

3D face modeling is a very important and challenging task in computer vision especially in the presence of an expression variation. It plays an important role in a wide range of applications including facial animation, human-computer interaction and surgery. Current 3D face imaging solutions are often based on structured light camera/projector systems to overcome the relatively uniform appearance of skin. This paper proposes a space-time scheme for 3D face scanning, employing three calibrated cameras coupled with a non calibrated projector device. The proposed solution is a hybrid stereovision and phase-shifting approach, using two \u03c0-shifted sinusoid patterns and a texture image. It involves a pattern-based face localization approach and an online projector parameterization. The experimental results further validated the effectiveness of the proposed approach.
