Description
Summary:In augmented reality (AR) systems, virtual objects, graphics or texts are added to the real scene to improve the person's perception. Virtual and real information must be aligned strictly in the combination of scenes. The key of augmented reality is 3D registration technology which is based on tracking the artificial marker in the scene effectively. Using linear programming theory, this paper presents a tracking method which can recognize the vertices of any convex polygon in augmented reality system since most of the markers are squares. The transformation matrix of camera can be estimated at the aid of coordinates of the four vertices.
