A combination of different non-destructive test methods is often necessary to receive reliable results for material characterization, flaw detection and the determination of component specific geometry parameters. Concerning concrete structures, thickness measurements combined with flaw detection and additional information about reinforcement and tendon ducts are needed. Therefore, a multi-sensor measurement approach is required with a high degree of automation. Otherwise a time consuming succession of manual measurements has to be performed which would prevent practical applications. Furthermore, the required information about material, flaws and component geometry is only gained when the multi-sensor data is combined for data analysis. Then high resolution results can be achieved.
