摘要
对多旋翼无人机在露天矿区地形图测绘进行应用研究,分析无人机在矿区地形图测绘的技术路线,通过案例,从无人机数据采集系统、像控点测量、航线规划及航拍、内业数据处理、实景三维测图等关键过程进行应用研究,对成果精度进行验证,证明满足《工程测量规范》中1:500比例尺地形图精度要求,该方法可以大大减少外业工作量,降低安全风险,保证成果精度,大大提高了工作生产效率,为矿区测绘提供了一种快速方便的方法。
Research on the application of multi-rotor UAV in topographic surveying of open-pit mines.Technical route of drone mapping was analyzed in the mining area.Through cases,detailed analysis was performed from key processes such as UAV data acquisition system,image control point measurement,route planning and aerial photography,interior data processing,and real-world 3D mapping.Accuracy of the results was verified and proved that it met the accuracy requirements of the 1:500 scale topographic map in the"Engineering Measurement Specifications".This method could greatly reduce the workload in the field,reduce security risks,ensure the accuracy of results,greatly improve work productivity,and provide a fast and convenient method for mining area surveying.
