TY - JOUR ID - citeulike:1726789 L3 - citeulike-article-id:1726789 N2 - Optical methods that give displacement or strain fields are now emerging significantly in the mechanical sciences. Much work has been done on two-dimensional (2D) displacement/strain measurement from a single camera but the proposed methods give only in-plane strains. A binocular correlation-based stereovision technique has been developed: to measure the three-dimensional (3D) shape of a static object or to measure the strains of an object undergoing some 3D mechanical or thermal stress. In this paper, the application of the stereo-correlation technique to measure accurately the 3D shape of a stamped sheet metal part or the surface strain field undergone by the part during the stamping process is presented.
