Paper Abstract

Digital image correlation is an effective way for accurate dimensional measurements with merits of non-contact and high precision abilities. Accurate calibration for the binocular stereo vision system is critical. A simple calibration method has been proposed in this study with the use of an inertial measurement unit (IMU) on each imaging station. As the IMU is aligned with the optical axis of the camera, the orientation of the camera is known. This helps in determining the rotation matrix of the extrinsic parameter of the camera based on the epipolar constraint relationship. The experimental results show that the proposed method has good accuracy and flexibility
