Precise geolocalization is crucial for unmanned aerial vehicles (UAVs). However, most current deployed UAVs rely on the global navigation satellite systems (GNSS) for geolocalization. In this paper, we propose to use a lightweight visual-inertial system with a 2D georeferenced map to obtain accurate geodetic positions for UAVs. The proposed system firstly integrates a micro inertial measurement un...
