The aerial camera systems used by IMF’s Photogrammetry and Image Analysis department were developed there both for research purposes and pre-operational use. These systems make it possible to record and immediately process high-resolution aerial images that are used especially for traffic and disaster management. Pre-processed image data and thematic analyses, for example traffic data, are transferred to a mobile or stationary ground station with an integrated microwave data link.
The DLR aerial camera systems were developed and certified for the Cessna (D-FDLR), the Dornier Do 228 212 (D-CFFU), the Dornier Do-228-101 (D-CODE) and for the Bo 105 (D-HDDP) and EC135 (D-HFHS) helicopters of the Eurocopter company.
The hardware configurations for the sensor systems depend on the particular aerial platform. The sensor on the Cessna and on the Do228 is referred to as a 3K system and on the helicopters as a 4k system. At an altitude of 1,000 m above ground and a focal length of 50 mm there is a ground resolution of 13 cm per pixel.
