Project “Measurement technology on flying platforms”

Project description

Fiber optic contact sensor for determining the relative movement between drone and measurement object for motion correction of a close-range 3D inspection lidar

Drone-supported object monitoring enables the identification of damage, e.g. to bridges or wind turbines. However, quantitative measurements, such as determining the damage depth of cracks or dents, are technically challenging, particularly due to disruptive environmental influences such as wind movements and vibrations of the object being measured.  To solve this problem, an innovative method is being developed that can directly measure the relative disturbing movements between the drone and the object. This is done using a fiber optic sensor which temporarily establishes direct contact between the drone and the object being measured. The information obtained can then be used to correct the actual measurement data and is to be used in this project, for example, in the 3D image stabilization of a close-range lidar.
