146 M.J. Hochrainer commercial systems, the webcam-setup performs well, however the lenses of the webcams have been identified as the limiting element. Therefore, a set of industrial cameras has turned out to be useful complement to the setup. When applying standard industrial cameras it possible to achieve accuracy similar to commercial DIC systems. References 1.
