摘要
文章以贵州省七星关区地理信息测绘任务为例,提出基于无人机遥感技术的地理信息测绘方法。分析该区域的地势情况,设计无人机遥感技术测绘流程;根据摄区实际地形起伏情况选择航摄设备,计算无人机的航摄高度、设计航摄路线,以完成不同起伏程度的地形航摄;采用基于局部方差均衡的图像增强方法对遥感图像处理后,对其进行镶嵌和裁剪,制作该区域的正射影像。对测绘成果进行分析后得出,该方法能够较好地完成研究区域的地理信息测绘,为该地区的自然资源管理提供可靠依据。
This paper proposes a geographic information mapping method based on unmanned aerial vehicle(UAV)remote sensing technology,using the example of the geographic information mapping task in Qixingguan District,Guizhou Province,China.By analyzing the terrain conditions in Qixingguan District,a UAV remote sensing technology mapping process was designed.Based on the actual topographic fluctuations in the survey area,appropriate aerial photography equipment was selected,and the UAV’s flight altitude was calculated,and flight paths were designed to complete aerial surveys of terrains with varying degrees of undulation.Remote sensing images were processed using an image enhancement method based on local variance equalization,and then mosaicked and clipped to produce orthophotos of the region.Through analysis of the mapping results,it was demonstrated that this method can effectively complete geographic information mapping in the study area,providing a reliable basis for natural resource management.
