CURe MODERN - Franco-German infrastructure inspection with unmanned air systems

This paper presents the investigations made at Fraunhofer IZFP within the INTERREG IV A Greater Region project CURe MODERN where different rotary wing micro UAS have been used together with ground-based robotic systems to scan infrastructures including bridges and monuments at high resolutions for damage assessment and monitoring purposes. The aerial pictures taken at high speed and frequency have then been stitched together to obtain full 2D and3D building surface reconstructions at a resolution allowing damages and cracking to be observed still in the millimeter range. With these ultra hi-res building reconstruction models a specific data base could be created for each object in order to provide extensive information for long term evaluation and life cycle management.
