Considering 3D measuring technology, X-ray tomography, heat flux thermography, shearography, terahertz measuring technology or image capture by means of the latest camera technology, it is not always easy to decide which quality assurance testing method for the user is best-suited because for most applications, image processing systems are still not off-the-shelf products. Often, it is necessary to choose from a wide range of different measuring methods depending on which is best suited for requirements, such as material properties, measuring accuracy or permissible test time. The training and further education offered by Fraunhofer's Business Unit Vision can assist decision-making.
