Abstract:
Numerous unmanned aerial systems (UAS) are currently flooding the
market. For the most diverse applications UAVs are special
designed and used. Micro and mini UAS (maximum take-off weight up
to 5 kg) are of particular interest, because legal restrictio
ns
are still manageable but also the payload capacities are sufficient
for many imaging sensors. Currently a camera system with fo
ur
oblique and one nadir looking cameras is unde
r development at the Chair for Geodesy
and Geoinformatics. The so-called "Four
Vision" camera system was successfully built and tested in the
air. A MD4-1000 UAS from microdrones is used as a carrier system
.
Light weight industrial cameras are used
and controlled by a central computer. For
further photogrammetric image processing, ea
ch
individual camera, as well as all the cameras together have to
be calibrated. This paper focuse
s on the determination of the re
lative
orientation between the cameras with the „A
ustralis“ software and will give an overvie
w of the results and experiences of test
flights.
