针对边坡稳定性评价研究的需要，提出了一种基于影像的露天矿边坡全自动三维重建方法。该方法利用普通数码相机获取露天矿边坡序列影像，基于运动恢复结构( SfM)和多视图立体视觉( MVS)算法，生成了稠密三维点云；通过构建不规则三角网和纹理映射，制作了边坡数字表面模型。试验结果表明：重建模型可全面表达露天矿边坡整体形态和局部细节特征，为有效评价边坡稳定性提供了科学依据；该技术具有成本低、高效、全自动等特点，非常适合存在潜在隐患的露天矿边坡动态变形监测。

To meet the demand of slope stability evaluation,a fully automated 3D reconstruction approach of open-pit slope from images was put forward. Open-pit slope sequence images were first collected with a consumer-grade camera. And then,dense 3D point clouds were generated by integrating structure from motion ( SfM) and multi-view stereo ( MVS) algo-rithms. Finally,high-resolution digital surface models of open-pit slope were made by constructing the triangular irregular net-work and texture mapping. The experiment showed that the overall form and local characteristics of open-pit slope can be accu-rately expressed through reconstructed model, which can provide powerful support for the correct analysis and evaluation of slope stability. The presented technology has the features of low cost,high efficiency,full automation,and it is especially suit-able for dynamic deformation monitoring of the open-pit slope in potential risk.
