摘要

采用双目立体视觉与数字图像相关相结合的新方法，对静载作用下湿喷桩复合地基室内模型的土体表面三维位移进行测试。给出了双目立体视觉系统的标定结果，提出了提取角点坐标的新方法及基于仿射变换的左右摄像机同名点的匹配搜索法，得到了土体表面三维位移随荷载变化的曲线。试验结果证明，将该系统应用于湿喷桩复合地基室内模型的土体表面位移测试是一种有益的尝试，也为土体位移测试提供了新的方法。

Abstract

Binocular stereo vision system and digital image correlation method are combined to measure3-D displacement of soil surface on wet jet pile composite foundation modal. The calibrated projection matrixes are determined. A novel method for extracting corner coordinates and a searching method for correlating the corresponding points of two cameras based on affine transformation are presented. 3-D displacement-load curves are obtained. The experimental results demonstrate that it is a valuable attempt to measure the surface displacement of soil on wet jet pile composite foundation modal using this system

and provides an efficient tool for the measuring of 3-D displacement of soil surface.
