OktoKopter with stereo vision

During the course of the R&D project ”InspektoKopter”, a modular test system and a novel method for external inspection of wind turbine rotor blades will be developed using an unmanned air vehicle, which is a safe and reliable alternative to current manual testing. The starting point is an existing multicopter system, which will be optimized for the use on wind turbines. To inspect the structural condition of the wind turbine blades, the development of a suitable optical inspection procedure is planned using appropriate camera and sensor technology. In addition to this, an analysis software for the identification of damage patterns, interpretation of the sensor data and visualization and archiving of the ”fitness” of rotor blades has to be implemented. Various detection methods shall help to recognize and localize surface damage (cracks ) or qualitative and quantitative material fatigue. The challenge here is the aggregation of individual sensor recordings consisting of image sequences and depth image scans, in an automatic workflow for creating a complex 3D model of the rotor blade under the particular scanning conditions. To ensure the reproducibility of the test, the automation of aerial surveys will be provided with the developed multi-sensor system which requires novel navigation technologies. A user-friendly software solution will be developed, that analyzes and annotates the optical measurement results and allows comparison of inspection data by some history mechanism.
