摘要
以青海省海西州乌兰县某测区为实验区,利用SfM-MVS(Structure from Motion with Multi-view Stereo)技术对无人机航摄数据进行处理,分析了不同控制点布设方案下的数据处理精度,完成了测区高质量三维点云数据的获取和DEM构建。结果表明:采用SfM-MVS技术处理数据能够满足实验区设计测图精度要求,该方法在高山地区大比例尺地形图测绘方面具有可行性。
The data of the UAV aerial data were processed by SfM-MVS （ Structure of Motion with Multi-view Stereo） technology, and the data of different control points were analyzed by using a survey area in Wulan County, Haixi County, Qinghai Province. The accuracy of data processing under different control points is analyzed, and the acquisition and DEM construction of high quality 3D point cloud data are completed. The resuits show that the SfM-MVS technique can meet the requirements of the design of the experimental area, and prove the feasibility of the method in large-scale topographic map.
