Workflow with the core steps in stereo-DIC processing: (a) Stereo calibration procedure to find intrinsic and extrinsic parameters of the optical system; (b) cross-correlated 2D-DIC and (c) 3D-DIC post-processing to calculate 3D coordinates of the triangular mesh’s vertices and to derive the full-field displacements.
