The VISTA system can be used to measure deformation ratios of bigger object zones in an automated manner within short time. The VISTA system takes gridcovered and formed sheets by a mobile measuring probe consisting of four CCD-cameras. Based on continuum mechanics algorithms taken over from map surveys, there are calculated the following parameters relevant for the metalforming procedure: deformation ratios, strains and sheet thickness variation for all measuring points.
