The NDT-Pyramids project will provide a basis for a more comprehensive and sustainable archaeological research at objects of our cultural heritage (CH) based on non-destructive testing (NDT) techniques. Prior to all measuring campaigns, a holistic consideration of the boundary conditions, the material properties and the available measuring techniques is performed based on simulations. A digital model of the object will be generated and all information available from the structure with be added. NDT techniques like RADAR, ultrasound or infrared-thermography will be simulated to evaluate their ability to detect voids or other artefacts inside of the object. As a result, the techniques best outperforming the required information can be selected along with sensor settings and sensor positions. This will establish a sustainable non-destructive (and if required non-contact) evaluation of structures of our cultural heritage.
