| 摘 要： | 随着无人机应用的普及和数码相机性能的提升，利用无人机搭载数码相机快速获取矿区航测影像，配合适量控制点得到符合精度的三维数据成为可能。本文介绍了一种采用测图鹰X100搭载SONY a7R数码相机进行外业数据采集，借助C++和OpenCV配合少量地面控制点进行光束法平差，并用PMVS算法生成密集点云的低成本快速高效露天矿三维重构方法。通过在露天矿试验，结果表明该方法所得DOM和DSM的平面中误差为0.113 m，高程中误差为0.121 m，邻近地物点间距中误差为0.151 m，均满足1：500地形图国家标准的精度要求。

| Abstract: | With the popularity of unmanned aerial vehicle ( UAV ) application and the improvement of the performance of digital camera,it is possible to use UAV with a digital camera to rapidly acquire the aerial survey video of the mine area and get 3D data which conforms to the precision by combining with control points.This paper introduces a low-cost,fast and efficient 3D reconstruction method of open-pit mine,which adopts mapping eagle X100 with a SONY a7R digital camera to conduct field data collection,uses C++ and OPENCV with a small amount of ground control points to conduct the bundle adjustment,and then adopts PMVS algorithm to generate dense point cloud.Through the experiments in open-pit mine,the results show that the DOM and DSM error in the plane is ±0.113 m,mean square error of height is ±0.121 m,adjacent feature point spacing error is ±0.151 m,which all meet the accuracy requirements of the national standard of 1 : 500 topographic map. |
