Paper Abstract

A novel calibration method that uses a planar object to determine the relative position and orientation between the CCD camera and the projector is developed. In this method the planar object is placed at different positions and orientations in the structured light system, the projector projects grids images on the plane, and the CCD camera takes images of the grids on the object. Using the fact that the object is planar we can recover the relative position and orientation between the CCD camera and the projector. An error model is also set up to correct the aberration of the light projector. Preliminary experiments suggest that this novel calibration method is flexible and is applicable to many shape measurement tasks.
