MAV Urban Localization from Google Street View Data

This approach tackles the problem of globally localizing a camera-equipped micro aerial vehicle flying within urban environments for which a Google Street View image database exists. To avoid the caveats of current image-search algorithms in case of severe viewpoint changes between the query and the database images, the authors proposed to generate virtual views of the scene, which exploit the air-ground geometry of the system. To limit the computational complexity of the algorithm, they rely on a histogram-voting scheme to select the best putative image correspondences. The proposed approach is tested on a 2km image dataset captured with a small quadroctopter flying in the streets of Zurich. The success of the approach shows
that the new air-ground matching algorithm can robustly handle extreme changes in viewpoint, illumination, perceptual aliasing, and over-season variations, thus, outperforming conventional
visual place-recognition approaches.
