Abstract

In this paper we show a new automated measuring system based on a fast optical coordinate acquisition device that performs the calculation of all the parameters characterizing the strain of an industrial piece. These results are obtained with high accuracy and in real time. An application of this improved system is illustrated and the whole measuring procedure is described in the following steps: grid marking on the metal sheet, stamping, coordinate acquisition, calculation of the strain parameters and their visualization
