It is proposed to develop a multiview framework to perform stere-ocorrelation by resorting to CAD-based descriptions of the observed 3D surfaces. Once the 3D surfaces have been reconstructed, the corresponding 3D displacement elds are measured within the same space. These elds are subsequently utilized to update isogeometric analyses to calibrate the elastic properties in a tensile experiment. An alternative route consists of preforming such analyses within an integrated framework.
