随着无人机技术的日益成熟,在各行业的应用越来越广泛。该项技术具有运行成本低、外业速度快、执行任务灵活性高、地形地貌对于生产作业影响因素小等优点,且能够适用于辅助选线、线路设计、巡线、以应急测绘为目的的快速正射影像图和专题图制作等诸多领域。本文对无人机航空摄影测量在长距离输油输气管道工程中的作业方法做了具体阐述。 With the increasingly mature UAV technology, more widely used in various industries. The technology has the advantages of low operating cost, fast operation, high flexibility of implementation tasks and small influencing factors of topography on production operations, and can be applied to auxiliary alignment, circuit design, patrol, and emergency mapping Rapid orthophoto map and thematic map production and many other fields. In this paper, the method of UAV aerial photography surveying in long-distance oil and gas pipeline project is described in detail.
