Trinocular ground system to control UAVs [PDF]

2009 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2009
In this paper we introduce a real-time trinocular system to control rotary wing Unmanned Aerial Vehicles based on the 3D information extracted by cameras located on the ground. The algorithm is based on key features onboard the UAV to estimate the vehicle's position and orientation.
