A 6DoF fiducial tracking method based on topological region adjacency and angle information for tangible interaction

In this paper, we describe a new method for camera-based fiducial tracking. Our new method is based on the combination of topological region adjacency and angle information, where as related works by Johnston’s RAG target [7], Costanza’s D-Touch [3], and Kaltenbrunner’s reacTIVision [2] are based on the uniqueness of the topological region adjacency structure. Such a combination of the topological region adjacency and angle information enables a wider unique ID range, while maintaining the merit of fast and robust fiducial tracking in topology-based approach. Our method makes it possible to obtain the 6 degrees-of-freedom (6DoF). Such problems of a narrow unique ID range and lack of 6DoF information have been the main deficits in most systems based on topological region adjacency approach, when compared to other fiducial tracking methods.
