山区测绘型低空无人机航线设计及优化研究

摘要

In recent years, UAV is increasingly applied in low-altitude aerial survey. In survey, ensuring field quality and efficiency is very necessary. Combined with practical experience and the main factors influencing the type of surveying and mapping low-altitude UAV route design, basic parameters, this paper mainly introduces general steps of the course design and the influence of the high pixel and long focal length camera on the ground resolution, aerial partition area and the efficiency in relief a large area; And how to ensure that there are enough overlapping degree between aerial photos, how to optimize the routes in the partition. In the end, it puts forward the high pixel, long-focus camera has a better applicability in volatile regions.%近年来无人机越来越多的应用于低空航测，如何保证外业质量和效率是很必要的。结合实际经验与影响测绘型低空无人机航线设计的主要因素、基本参数，文章重点介绍了航线设计的一般步骤和在地形起伏较大区域选用高像素，长焦距相机对地面分辨率、航摄分区面积、作业效率的影响；以及如何确保航片间有足够的重叠度，如何在分区内优化航线。提出了高像素，长焦距相机对起伏较大区域有更好的适用性。
