摘要
介绍了无人飞艇低空航摄测量系统,利用此系统对博兴县城区约15 km2的区域进行航摄测量、空三加密并制作DEM和DOM,各项指标均达到了国家1∶1 000航摄测量的精度要求。对比载人飞机,无人飞艇机动灵活,获取的影像数据分辨率高,数据获取快及处理效率高,精度满足国家标准的要求,成本低廉。
This paper introduces the unmanned airship low-altitude aerial photogrammetry system; using this system to the Boxing County city of about 15 km2 conducted aerial photogrammetry, aerial triangulation and the production of DEM and DOM. The indicators have reached the national 1:1 000 aerial survey precision. In contrast to manned aircraft, unmanned airship is flexible, the required image data of high resolution, fast data acquisition and the processing efficiency is high, and the precision can satisfy the national standard and the coast is low.
