| Abstract | To improve the accuracy of stereo matching of DIC method, a correction method based on epipolar constraint for 3D-DIC stereo matching is proposed in this paper. The initial stereo matching result is obtained by DIC method, and then the initial results are corrected by epipolar constraint. The point on the right pole line, which is nearest to the initial result of DIC method, is regarded as the new matching point on right image. In addition, this method is also used to match right sequential images. The tensile test of 304 stainless steel specimen is conducted on material testing machine. Compared measurement error of the proposed method with that of stereovision method without correction, experimental results show both the maximum error and average error of the proposed method decrease through correction by epipolar constraint, this testifies that the proposed method can improve the measurement accuracy of stereovision method. |
