单兵无人机测量系统在美丽乡村建设中的应用

Application of Single-soldier UAV Measurement System in the Beautiful Countryside Construction

单兵无人机测量系统以其便捷、灵活、地形适应性强等特点已在测绘行业得到广泛的应用,本文以甘肃省康县一带一路国际论坛会馆周边29个村美丽乡村建设项目中的左家村为例,进行1∶1000地形图测绘及三维立体模型建设。针对项目航飞区地处中高山区、地形陡峭、村庄分布零散、航飞困难大等特点,提出采用单兵无人机航测获取数字影像、ContextCapture软件实景三维建模、EPS软件裸眼立体三维测图方案,并对精度进行了充分验证。其检查点平面位置中误差为0.0678 m,高程中误差为0.051 m,均小于规范要求的0.1 m。结果表明:单兵无人机测量系统具有高效快速、作业成本低、生产周期短等特点,可一定程度上突破自然条件和高危地区执行飞行作业的限制,能满足大比例尺地形图测绘要求。

Single-soldier UAV measurement system has been widely used in surveying and mapping because of its convenience,flexibility and terrain adaptability,based on Zuojiazhuang Village of beautiful rural construction around One belt,One road International Forum are carried out in the 29 villages in Kangxian County,Gansu Province as an example,the 1∶1000 topographic mapping and 3D model construction.The project area is located in the middle and high mountains,with scattered villages and great difficulty in photogrammetry,in this paper,we propose a method to obtain digital images by single-soldier UAV,3D modeling by ContextCapture software and 3D mapping by EPS software.The results show that the mean square error of plane position and mean square error of elevation is 0.0678 m and 0.051 m respectively,which are less than 0.1 m required by the specification.The results show that the single-soldier UAV measurement system has the characteristics of high efficiency,low operation cost and short production cycle,which can break through the restrictions of natural conditions and high-risk areas to some extent,and can meet the requirements of large-scale topographic mapping.
