| Summary: | This paper reports on the investigations made at Fraunhofer Institute for Non-Destructive Testing (IZFP) where different rotary wing
micro UAS have been used to scan infrastructures including bridges and monuments at high resolutions for remote damage
assessment and monitoring purposes. The aerial pictures taken at high speed and frequency have then been stitched together to
obtain full 2D and 3D building 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. The UAS also have been equipped with sensors for
damage size estimation, which combined with an image processing software developed to allow automatic cracking pattern
recognition could be used for further analysis. |
