摘要
当前无人机低空测绘越来越多的应用于地形图测绘或者是灾害监测等领域,无人机测绘的技术优势明显,尤其是在地形图测绘中,运用无人机实行空中摄影,不但风险不高,而且速度还非常快,其在很大程度上减少了投资成本,而且在打区域里应用无人机进行测绘,还可以进一步提高地形图绘制的精确度。对此,此文简单介绍了无人机航测系统的结构,详细分析了无人机航摄摄影测量技术的常见特点,并研究比例无人机在地形图测绘中的具体应用情况。
At present,UAV low altitude surveying and mapping is more and more used in topographic mapping or disaster monitoring and other fields.Technical advantages of UAV surveying and mapping are obvious,especially in topographic mapping,using UAV to carry out aerial photography is not only low risk,but also very fast,which reduces investment cost to a large extent and also can further improve accuracy of topographic mapping by using UAV in large area.In this paper,structure of UAV aerial survey system is briefly introduced,common characteristics of UAV aerial photogrammetry technology are analyzed in detail and specific application of proportion UAV in topographic mapping is studied.
