Computer Vision for Shape and Deformation Measurements: Recent Developments and Applications

Applications using two-dimensional and three-dimensional computer vision for deformation and shape measurements are described. First, the use of 2D image correlation for estimation of properties in heterogeneous materials is demonstrated. Second, the use of 3D computer vision for shape and deformation measurements in large, flawed panels is presented. Finally, the use of 3D computer vision for deformation measurement in cracked, ductile materials undergoing complex loading conditions is shown.
