Abstract :
This paper presents a novel method for the calibration of a structured light configuration, which is a particular case of a stereoscopic system in which one of the cameras is replaced by a projector. The method uses vanishing points to remove the keystone effect and to extract the parameters of the projector and of the camera. The calibration is performed using a simple flat surface with orthogonal edges and no texture. The result is a simplified calibration technique which does not need complex calibration objects and that can be used in 3D reconstruction applications. The model obtained is validated through depth estimation measurements in a real scene.
