DOI: 10.1016/j.optlaseng.2021.106809
Abstract: Abstract Stereo-digital image correlation (stereo-DIC) is now a standard technique for determination of the mechanical properties of materials and structures. In stereo-DIC, cameras are assumed to be motionless after camera calibration, so the three-dimensional (3D)… read more here.

DOI: 10.1109/tim.2022.3211567
Abstract: Bi-prism-based single-bilateral-telecentric-camera stereo-digital image correlation (SBTC stereo-DIC) is a recently developed variant of single-camera stereo-DIC technique, featuring attractive advantages of easy implementation, calibration-free imaging model, and high accuracy. However, the effects of key structural parameters… read more here.
