无人机航测技术在某公园地形测量中的应用

The application of UAV aerial survey technology in topographic survey of a park

随着测绘技术的发展,无人机航测以其快速、便捷、经济的特点在测绘行业中得到快速应用。无人机航测是通过无人机飞行器搭载配套相机镜头、飞控软件、获得带像控点的航片,再通过专业软件进行数据处理得到DOM与DEM,最后生产出DLG数字线划地图。通过实际在《王家山森林运动公园地形图》航测中的应用,详述了无人机测绘技术在进行地形图航测作业的技术路线和作业流程,为类似项目进行航测提供参考。

With the development of surveying and mapping technology,the UAV aerial survey had been applied rapidly in surveying and mapping industry because of its fast,convenient and economic characteristics.UAV aerial survey was to get aerial photos with image control points through UAV equipped with camera lens and flight control software,then get DOM and DEM through data processing by professional software,finally produced DLG digital line map.Through the actual application in aerial survey of Topographic Map of Wangjiashan Forest Sports Park,this paper elaborated the technical route and operation process of UAV surveying and mapping technology in aerial survey of topographic map,so as to provide reference for aerial survey of similar engineering.
