AR.Drone – user upload (video summary)
This video has been uploaded to The-Parrot-ARDrone.com by user imrfel. Here is a summary of the video in their own words:
This video shows a fully autonomous unmanned aerial vehicle following a short pre-learned path. The quadcopter is first manually guided around by a teleoperator. During the teleoperated flight, image processing algorithms (SURF,SIFT) recognize salient objects from the image of the on-board camera. Positions of these objects are estimated and put in a threedimensional map. In the autonomous mode, the quadcopter loads a relevant map and matches the mapped objects to the currently visible ones. In this way, the quadcopter is able to estimate it position with a precision higher than conventional GPS. Details on the navigation method are in the article: Krajnik et.al. : “Simple, Yet Stable Bearing Only Navigation”, Journal of Field Robotics, Sep, 2010.
