本文介绍了一种利用数字图像相关技术测量表面轮廓的系统。所有需要的相机校准和系统的轮廓测量的方程。方程包括需要的变换，以考虑子集透视失真。该系统能够达到摄像机到物体距离的1/20，000的精度。几种情况下的实验结果，结果给出了0.05毫米的最大误差与相机到物体的距离为1000毫米。
Presented in this paper is the development of a system for measuring surface profile using digital image correlation. All needed equations for camera calibration and system profile measurements are shown. Equations included needed transformation to account for subset perspective distortions. The system is capable of an accuracy of 1/20,000 of the camera-to-object distance. Experimental results are shown for several cases, with results giving a maximum error of 0.05 mm with camera-to-object distance of 1000 mm.
