摘要
本文首先介绍无人机航测的一般流程及内业数据处理的几个关键点,根据实际作业情况,提出运用正射影像直接提取地理信息数据与立体测绘相结合生产数字线划图的方法。
This paper introduced the general process of aerial surveying based on the unmanned aerialvehicle(UAV)and a few key points of data processing in office.According to the actual operation situation,proposed a method that produced DLG by extracting geographic information data by DOM and the stereo mapping.
