Mobile Augmented Reality at the Hollywood Walk of Fame

This work introduces techniques to facilitate large-scale Augmented Reality (AR) experiences in unprepared outdoor environments. We develop a shape-based object detection framework that works with limited texture and can robustly handle extreme illumination and occlusion issues. The contribution of this work is a purely geometric approach for detecting marker-like objects under difficult and realistic outdoor conditions. We demonstrate these techniques for mobile AR experiences by detecting and tracking star-shaped pentagrams embedded in the Hollywood Walk of Fame at 30Hz on a Nokia N900 phone.
