摘　　要：无人机航摄搭载的相机一般是普通的非量测数码相机,具有影像像幅小和高重叠度的特点,这些特点更适宜用于制作真正射影像。本文研究了基于无人机系统的真正射影像制作方法,分析了制作过程中航摄参数设计、数据获取、空三加密、数字表面模型计算和正射纠正的五个关键步骤,并对真正射影像的精度进行了验证,研究表明基于无人机系统可以用于制作高精度的真正射影像。The camera on UAV aerial photography is a commonly non-metric digital camera with the characteristics of small image size and high overlapping,these chavacteristics make it be more suitable for making TDOM.This article mainly studied the TDOM making method based on UAV system,including the following five key parts.Aerial photography parameter design,data collection,air encryption,DSM caiculation and ortho-rectification.The accuracy of TDOM was verified in the aspect of plane and elevation coordinates.The research showed that UAV systems can be used to make high-precision TDOM.
