| 摘 要： | 使用单个摄像机的二维数字图像相关方法通常仅局限于平面物体的面内变形测量,而使用两个摄像机基于双目立体视觉原理的三维数字图像相关方法克服了这一局限,可对平面和曲面物体表面的三维形貌和载荷作用下的三维变形进行测量。本文介绍了三维数字图像相关方法的基本原理及其关键技术,并用两个典型的实验验证了该方法的有效性。

| Abstract: | Two-dimensional digital image correlated with single camera is limited to in-plane deformation measurement of a plane object.Based on three-dimensional binocular vision principle,the advanced three-dimensional digital image correlation(3D-DIC) method breaks through this limit and can measure the three-dimensional shape and deformation of both plane and curved surface under a loading.In this paper,the basic principle and key techniques of 3D-DIC are presented,and two typical validity check experiments were carried out to validate the 3D-DIC. |

| Keywords: | digital image correlation(DIC) three-dimensional vision camera calibration deformation |
