NAVTEQ’s 3D Street Mapping

Filed under: Uncategorized — Jing Gao @ 8:54 pm

The LIDAR point cloud image of radiohead reminded me of a talk that I went to last semester, given by NAVTEQ engineers.  NAVTEQ has been collecting and processing huge amount of LIDAR data from mobile devices carried by auto vehicles.  The immediate result of this is a huge coverage of 3D street map, which has partnered with Bing Maps.  Moreover, NAVTEQ has developed a system to automatically extract and recognize road features, such as traffic signs and lane markers, which is used for the navigation system to provide more detailed driving instructions and warnings.  So, maybe soon enough the car will start complaining about speeding.
