| 摘 要： | 随着社会需求的不断提高,真正射影像图的应用范围越来越广。带有差分GPS小型旋翼无人机的出现使低成本的生产大面积区域的真正射影像图成为可能。本文从无人机航摄外业、数据预处理和空三加密3个方面详细阐述了关键环节的作业方法,并以邯郸市武安摄区为例,在免像控的情况下完成了86.19 km2的真正射影像图制作。通过实测检查点验证成果精度,结果表明:平面精度满足1∶500比例尺成图精度要求,为生产真正射影像图提供了行之有效的解决方案。

| Abstract: | With the increase of social needs,the application of TDOM is more and more extensive.The advent of Small-Multi-Rotor UAV with differential GPS makes low-cost production of TDOM in large area possible.From the aspects of UAV aerial photography,data preprocessing and three-dimensional triangulation,the key methods of operation are elaborated in detail.Being an example case,the production of TDOM in 86.19 km 2 is completed without any control point in Wu'an area,Handan city.The accuracy of the TDOM is verified by the error of the checkpoints.The result shows that the coordinate accuracy meets the accuracy requirement of 1∶500 scale TDOM.In the process and though the result,this paper provides an effective solution for the production of TDOM. |
