Abstract

Camera vibration is one of the main factors affecting the measurement accuracy of stereo-DIC. It is difficult to keep fixed of the cameras in the field because of wind loads and ground vibrates. Currently, the research on camera vibration correction for Stereo-DIC in field measurements is fairly limited. This study proposes a camera vibration correction method based on fixed background points and motion model parameters. The background points are used to calculate the motion parameters of two cameras, and then the image coordinates of the interesting points that eliminate the global motion are estimated. The proposed method avoids repeated calibration of extrinsic parameters by correcting the motion of each camera separately. To verify the proposed method, an experiment in which the stereo cameras occurred relative movement was performed. Experiments shown that the proposed method has effectively corrected the effects of camera movements.
