3D endoscopy and damage detection in narrow installation spaces (SFB 871 T14)

The inspection of aircraft engines is currently carried out using a flexible video endoscope. The images are analyzed and assessed by a highly specialized employee. This process is very time-consuming and does not provide a quantitative assessment of the condition of the engine components. In the T14 transfer project, this process is to be automated to enable quantitative quality control of compressor blades.

An important research focus is the measurement of the damage and the determination of the position on the blade. This requires an overall measurement of the blade, which is determined from the registration of several individual measurements. The different measurement poses of the sensor are required for the registration. For this purpose, a fast measurement mode is implemented to enable tracking of the sensor.

In the later course of the project, influences on the measurement uncertainty depending on the sensor pose and the sample topology are to be investigated in order to reduce them.
