基于中型固定翼无人机航摄系统的大比例尺测图精度评估探讨

摘要

针对低空无人机航摄系统工作效能与测量精度方面的问题,笔者所在团队研发了一套无人机航摄系统,在新疆和田某荒漠区开展了航摄试验,对无人机航摄系统获取的航摄影像平面精度及测高精度进行评估,结果表明:成像结果可以满足1∶1 000地形图测图的平面精度要求.%Aiming at the problems of working efficiency and precision using low altitude UAV aerial photographic system,our team achieved an unmanned aerial system,in a desert area in Hetian carried out aerial test.the paper introduces the aerial system,gives a specific test process,the results show that,imaging results can be meet the requirements of 1∶1 000 topographic mapping plane precision.
