摘要
针对露天矿对三维实景模型的高精度、精细化真实还原等需求,采用飞马D2000多旋翼无人机搭载Sony a6000相机通过变高航飞获取多视角高分辨率影像数据,利用Context Capture软件进行空三加密生成三维实景模型,并利用检测点进行精度评定.研究结果表明:点位误差为4.33 cm,高程误差为5.75 cm,结合SketchUp个体景观建模构建赛道小镇三维精细实景模型,符合露天矿整体规划及建设的精度要求,不仅实现赛道小镇整体空间规划及决策分析,而且实现基于三维场景的地形图检核和土方计算.
According to the requirements of high precision and fine real reduction of the 3 D real scene model of the open-pit mine in Xinqiu,using Feima D2000 multi rotor UAV and Sony a6000 camera to obtain multi-view and high resolution image data through variable altitude flight.The 3D real scene model was generated by space three encryption by Context Capture software,and the accuracy was evaluated by using the detection points.The results show that the mean square error of the point was 4.33 cm,and the mean square error of elevation is 5.75 cm.Combined with SketchUp individual landscape modeling,the 3D fine real scene model of the track town is constructed,which meets the accuracy requirements of the overall planning and construction of the open-pit mine.It not only realizes overall spatial planning and decision analysis of track town,but also realizes the application based on 3D scene,such as the check of topographic map and the calculation of earthwork.
