Abstract

At the Hochschule Offenburg, a fully controlled helicopter has been developed, which is very easy to fly by anybody and can be flown very close to objects. The flight control system consists of an attitude and heading reference system, an inertial navigator augmented by GPS and a flight control computer. The electrically driven helicopter can easily carry payloads of more than 1 kg. With this helicopter high resolution pictures were taken from parts of the Freiburg cathedral. Also pictures with a calibrated camera of terrain have been taken. Pictures were paired and using a commercial software, a 3D-model of a part of the top of the "Hahnenturm" of the Freiburg cathedral has been generated. The terrain pictures have been bundled and used to precisely measure the position of certain objects in the terrain. The first results of these trials are very promising in respect to future applications of the helicopter.
