ABSTRACT
Surface recordings of concrete bridges with laserscan or digital imaging with the aid of drones are used to detect superficial damages on bridges.This method is more time-saving than the conventional, more complex procedures for visual inspections. In order to be able to also detect damages below the surface by means of areal recordings, a promising approach - thermography - is investigated. A big advantage of thermography is that the cameras can be applied on drones. Together with photogrammetric reconstruction a rapid recording of the entire bridge can be carried out. This method makes it possible to detect damages such as delamination, voids and moist areas in the concrete to a certain degree. Now the aim is to determine the suitability of this method for the detection of the mentioned damages with regard to the detection accuracy and limits. This paper is a summary and translation of an article submitted in a German Journal.
