无人机航测在大比例尺地形图测绘中的应用探究

Application of UAV Aerial Survey in Large Scale Topographic Mapping

无人机航测技术本身具备成本低、灵活性高等特点,可以在地理空间信息数据获取中展示出良好作用。本文根据以往工作经验,对航空摄影测量的发展进行总结,并从地面站控制系统、航线及像控点布设、空中三角测量、POS技术辅助空三加密四方面,论述了无人机航测在大比例尺地形图测绘中的应用。

UAV aerial survey technology has the characteristics of low cost and high flexibility, which can play a good role in geospatial information data acquisition. This paper summarizes the development of aerial photogrammetry based on previous work experience, and discusses the application of UAV aerial survey in large-scale topographic mapping from four aspects: ground station control system, route and image control point layout, aerial triangulation, POS technology-assisted aerial three-encryption.
