摘　　要：为保障青海木里矿区生态整治工程有序而高效的实施,采用了无人机航空摄影测量技术,定期快速获取矿区正射影像,结合地面控制测量数据和青海CORS数据,及时处理影像数据得到矿区DSM和DOM数据。利用不同期次的DSM数据,应用ArcGIS软件对DSM数据进行差分运算获得矿区高程差DSM数据。然后应用栅格法计算获得各整治矿井的不同时间节点的高精度的挖、填方量。研究表明,无人机航测技术在木里矿区生态整治项目中发挥了重要作用,为工程实施提供了有力保障。To ensure the orderly and efficient implementation of the ecological remediation project in the Muli mining area of Qinghai,unmanned aerial vehicle(UAV)aerial photogrammetry technology is used to regularly and quickly obtain orthophoto images of the mining area.Combined with ground control measurement data and Qinghai CORS data,the image data is processed in a timely manner to obtain DSM and DOM data of the mining area.Using DSM data from different periods,ArcGIS software is applied to perform differential operations on the DSM data to obtain the elevation difference DSM data of the mining area.Then,the grid method is applied to calculate the high-precision excavation and filling quantities at different time nodes of each mine being renovated.Practice has shown that drone aerial surveying technology has played an important role in the ecological remediation project team of the Muli mining area,providing strong support for the implementation of the project.
