摘要
为满足无人机航摄制作数字线划图达到一般航摄测图精度要求,本文采用无人机搭载1亿像素相机,通过高分辨率及大重叠度航摄获取原始数据,结合实景三维建模软件进行空三,开展建模并输出数字正射影像满足外业调绘,同时建立立体模型满足数字线划图采集需求,最终制作的模型效果直观真实,数字线划图精度达到一般航摄成图相应的精度要求。
In order to make UAV mapping meet the requirements of traditional aerial photography accuracy,this paper uses UAV equipped with a 100 million pixel camera to obtain high-resolution and large-overlap original images,combined with real-scene 3D modeling software for aerial triangulation.Then,produce digital orthophoto map(DOM)that meets the field adjustment and mapping,and establish three-dimensional model that meets the requirements of digital line graphic(DLG),and finally obtain real-life 3D models and digital line graphics that meet the requirements of traditional aerial photography accuracy.
