Two field campaigns in which METAIR or ARA have operated their small manned aerial platforms are re-analysed to give an example of the considerations that should be evaluated
Recent and ongoing developments of state-of-the-art sensor technologies have resulted in smaller and lighter photogrammetric cameras with IMU, lidar scanners (Eisenbeiss,
The most-widely used meteorological sensor package is calibrated for an airspeed of 22 m/s. It was planned from the beginning of this project to design an aircraft
Before computing the correlation map, the sensed image is scaled and aligned to the reference image using the altitude information from the pressure sensor (as for the odometry)
The field campaigns enabled to eval- uate the conditions of a reliable detection of fawns in the meadows by thermal imaging. It has shown that the man- ual detection is fast
After conducting the aerial survey and manually sorting the imagery 99 pictures have been used to compute 3D point clouds by using all presented software
A typical image-based field surveying with UAV systems require a flight or mission planning, GCPs measurement (if not available and required for geo-referencing), image
The airspace above Belgium is classified using the international classes A-G, that depend on (a) the flight rules, (b) requirements on the aircraft and (c) the minimal
