UAV (Unmanned Aerial Vehicle) systems became relevant for applications in precision farming, digital photogrammetry, stock piling and in infrastructure maintenance. The advantages of a photogrammetric system on-board of an Unmanned Aerial Vehicle are mostly low cost and flexible and therefore a suitable alternative solution compared to other mobile mapping systems.
With an orthophoto and a DEM derived from aerial images in a scale of 1:5000, a flight planning was build up. The determined flying positions were implemented in the flight control system. Thus, the Uav is able to fly to predefined pathpoints automatically. Tests in Central Macedonia – Greece and the flights in Skydra showed that using the built-in GPS/INS and stabilization units of the flight control system, predefined positions could be reached exactly to acquire the images.
