基于CORS系统与无人机遥感技术的大比例尺测图

文章以厦门市鼓浪屿为例,在对其人口统计数据、地名数据库等资料分析的基础上,介绍了利用无人机系统和FJCORS系统进行航拍、控点测量及影像精度评定,解译制作建筑分布图,将数据进行三维重建,制作地籍数据库的技术方法与工作流程。研究表明,无人机大比例测图的精度高,机动性强,操作方便快捷,明显优于传统测图方法,可为工程项目和测图提供可靠参考。

Taking Gulangyu in Xiamen as an example, based on the analysis of its demographic data and toponymic database,this paper introduces the aerial photography, control point measurement and image accuracy evaluation using UAV system and FJCORS system. The technical method and work flow of building layout map interpretation, 3D reconstruction of data and cadastraldatabase production. The research shows that the large scale mapping of UAV has the advantages of high precision, strong maneuverability, convenient and quick operation, which is obviously superior to the traditional mapping method, and can provide reliable reference for engineering projects and mapping.
