In recent years, UAV aerial survey technology has been adopted in more and more projects. This article combined actual project, briefly discussed the development of UAV flight plan, the preparation of work before flight and the data processing after the flight. The paper summarized the work process and matters needing attention of UAV aerial survey technology, finally analyzed the problems in the process of production and compared measurement accuracy verification, aiming to explore the UAV aerial technology in large scale 1: 2000 topographic map, the feasibility of the application of measurement the accumulated valuable experience was discussed.%近年来,随着无人机航测技术的发展,越来越多的生产项目中采用了此项技术,结合单位实际生产项目,从无人机航飞计划的制定、航飞前的工作准备和航飞及其之后的数据处理三个方面进行简要论述,将无人机航测技术的工作流程、注意事项进行归纳总结,最后对生产过程中的问题进行分析并对其测量精度进行对比验证,旨在探究无人机航测技术在小范围1:2 000地形图测量中应用的可行性,并为无人机航测技术的应用积累宝贵经验.
