Abstract :
Our work stems from a program focused on developing tracking technologies for wide-area augmented realities in unprepared outdoor environments. Other participants in the Defense Advanced Research Projects Agency (Darpa) funded Geospatial Registration of Information for Dismounted Soldiers (Grids) program included University of North Carolina at Chapel Hill and Raytheon. We describe a hybrid orientation tracking system combining inertial sensors and computer vision. We exploit the complementary nature of these two sensing technologies to compensate for their respective weaknesses. Our multiple-sensor fusion is novel in augmented reality tracking systems, and the results demonstrate its utility
