摘要
为提高海岛测绘的技术手段,将无人机引入海岛地形调查中,以Swallow-P小型固定翼无人机开展惠州市大亚湾虎洲海岛大比例尺测图为例,系统归纳了无人机外业数据采集与内业数据处理的具体流程,并制作了DEM和DOM成果;经过实测地面点精度分析得出虎洲无人机大比例尺测图成果平面位置中误差和高程中误差符合1∶1000测图精度要求。
In order to improve the technical means of island survey,the UAV technology is introduced into the topographic survey of islands.Taking the large scale mapping of Huzhou island in Dayawan,Huizhou based Swallow-P small fixed wing UAV as an example,this paper summarizes the specific process of external data acquisition and internal data processing,makes DEM and DOM.Precision analysis is provided of measured ground points,the plane position error and elevation error of the large scale mapping results of Huzhou island UAV meet the accuracy requirement of 1∶1000 mapping.
