Real-time Panorama Mapping and Tracking on Phones
“[Studierstube] have implemented a system for the online creation and simultaneous tracking of panoramas. [Their] system uses a natural feature mapping and tracking method, which is sufficiently efficient and robust to allow 3 degrees of freedom tracking on mobile phones. Assuming pure rotational movements, the method creates an panoramic map from the live camera stream, at the same time tracking the generated panorama.”
Runs at 30fps on the ASUS P565 mobile device which packs a pokey 800MHz processor. It uses their PatchTracker algorithm, a 3DOF natural feature tracker described in this PDF presentation. Here is more detailed information on their 6DOF natural feature tracker also for mobile devices.
