天狼星无人机大比例尺测图精度分析

Precision Analysis of the Large Scale Mapping Based on Sirius UAV

无人机航测技术的发展已经日渐显著,越来越多的航测无人机野外作业可以满足大比例尺地形图精度要求,提高了作业效率。拓普康天狼星无人机具有高精度的航测系统,并在无人机航测领域内首次实现了无地面像控的测量方式,具有明显的可操作性优势。本文以1∶500大比例尺测图精度要求为标准,对天狼星无人机小范围地形测图精度进行了验证分析,为相关航测项目需求提供参考。

The development of UAV aerial photography technology has been more and nmre obvious, which makes more and more aerial photography UAV field operations meet the accuracy requirement of large scale topographic map and improve operalion efficiency. Topeon Sirius UAV is a high precision aerial photography system, and in the field of UAV aerial image measurement is realized for the first time without ground control, has obvious operational advantages. Based on the accuracy requirement of 1 ： 500 large scale mapping, the accuracy of small range topographic mapping of Sirius UAV is verified and analyzed, and it provides reference for the needs of related aerial photography projects.
