Paper Abstract

We present in this paper a stereovision system that has been developed in Ecole des Mines d'Albi Material Research Center laboratory for the automatic measurement of 3D deformed surfaces, in collaboration with the LAAS-CNRS laboratory. This method uses off-the-shelf lenses, CCD cameras and frame grabber, and requires that a predefined pattern be applied to the sheet surface before stamping. The system works in three steps: (i) the stereovision system is first calibrated, (ii) two images of the part to be measured are taken and the 3D coordinates are computed, (iii) the strains are calculated from these 3D coordinates.
