Structured light 3D face scanning system

The paper proposes the integration of a structure lighting system on a gantry to improve its flexibility, efficiency and accuracy of 3D reconstruction for face modeling. A method for the integrated system calibration to calculate the correspondences between the coordinate systems of the camera, the light source and the rotational axis is also proposed. Parameters obtained from calibration are used to calculate the 3D data from the acquired 2D images. Experiments have been performed to demonstrate the effectiveness of the proposed method when applied to the 3D reconstruction of human face. The proposed system is able to obtain more accurate 3D models of objects with reduced time.
