Stereo camera tracking for mobile devices

We present our current work on a camera tracking algo-rithm designed for a mobile device equipped with a stereo camera. The tracker runs in real-time on a prototype mo-bile platform and it can be used as the core engine of aug-mented reality applications. In order to cope with the lim-ited resources available, we design an algorithm that re-lies on the stereo camera only for the 3D reconstruction of points, while the point tracking is performed only on one of the two images, thus reducing the computational effort. We show some preliminary results in which the camera tracker as been validated in a realistic scenario and it is proved to have an adequate robustness for an augmented reality ap-plication. 1
