Project description Authorized for use in German airspace since 2004, gyrocopters possess a range of characteristics that make them ideally suited to the recording of image mosaics. In particular, their highly stable flight dynamics – even at low airspeeds – facilitate extremely cost-efficient, comprehensive data capture over wide areas with the aid of TIR and RGB cameras characterized by a high level of geometric resolution. The project is faced by the following key scientific-technological challenges: 1. The development of a navigation solution which enables pilots to follow an extremely precise course (i.e. accurate to within 10 m of the target position) over a flight time of several hours. 2. The integration of a low-cost inertial solution into the photogrammetric bundle adjustment concept for TIR and RGB images characterized by numerous additional parameters such as residual drift, optical distortion and boresight misalignment, which represents a ground-breaking step forward in the automatic alignment of large image mosaics. 3. The presentation of scientific proof that it is possible to control vibration damping and temporally synchronize all sensors in a way which ensures that the product of the data capture process (i.e. the image mosaic) is geographical accurate to at least one pixel per ground point.
