Vision-Based Registration Using 3-D Fiducial for Augmented Reality

One of the key issues in the realization of Augmented Reality is the registration problem. Synthetically, vision-based registration can offer superior solutions. In several existing registration methods, 2-D objects or pictures are used as positioning fiducials, and at least two cameras and/or separate tracking devices are needed.A new registration method is proposed which uses a solid fiducial and a single color CCD camera.The new method significantly simplifies the registration system and eliminates tracker-to-camera errors.
