Abstract

In this paper, a multi-camera DIC system with semi-circular configuration which can capture images from three different view angles at the same time is introduced. The multi-camera DIC system associated calibration method is proposed, the internal- and external- parameters of all system’s cameras by utilizing a planar plate with circular marks on it. A cracked cylindrical were reconstructed with images obtained by the proposed three-camera systems, with the help of digital image correlation method is also demonstrated and discussed.
