SPP 2433
Priority Programme 2433 ‘Messtechnik auf fliegenden Plattformen’
There is a steadily increasing demand from society and industry for measurement and sensor systems for free-field measurements. For example, to understand the impact of unpredictable environmental influences on buildings, facilities and plants, and for carrying out maintenance tasks. Of particular interest is therefore the space close to the ground up to approx. 500 m, which humans inhabit, intensively organise and manage. The question always arises as to which measuring system carrier can be used to carry out fast, resource-saving and high-quality measurements? And how can measurements be carried out at high altitudes and in places that are difficult to access, such as offshore wind turbines, without exposing people to danger?
The priority programme therefore aims to explore new measurement capabilities and clarify the measurement quality of measurement technology on flying platforms. This makes it a unique network of 19 interdisciplinary research projects that will lay the foundations for future mobile measurement systems.
In fact, uncrewed aerial vehicles (UAVs) still offer unexplored potential for use as mobile measurement system carriers because civilian drone technology is still very young compared to other mobile systems and is constantly making technological progress. A crucial point here is that, to date, qualitative information has tended to be extracted from image data, particularly using artificial intelligence, while there are hardly any quantitative measurements with measurement uncertainties. However, if, for example, a statement is needed about the load-bearing capacity of a damaged bridge or the structural integrity of the rotor blade of a wind turbine, only measured values with uncertainty information can lead to a reliable statement. This involves dealing with tightly limited resources in terms of weight, installation space, energy and time, and drone and environmental influences, some of which are unpredictable, interfere with the measurement. The focus of the joint research efforts is therefore on clarifying and minimising the measurement quality that can be achieved for different measurement variables and on a standardised assessment of the measurement quality in conjunction with the resources used.
