摘要: 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 proposed only in-plane strains. A binocular correlation-based stereovision technique developed: (a) to measure three-dimensional (3D) shape of static object (b) strains an undergoing some 3D thermal stress. In this paper, application stereo-correlation accurately stamped sheet metal part surface field undergone by during stamping process is presented.
