摘要
无人机遥感系统是一种新型的高分辨率影像数据快速获取方式,具有高效快速、精细准确、作业成本低等特点。本文介绍了无人机遥感系统的组成、特点,设计了无人机遥感系统在国土资源执法监察中应用的技术流程,并以芜湖县湾沚镇为航摄区域进行实例验证分析。通过遥感影像的几何校正、空三加密、图像拼接和数据精度分析等数据预处理,套合比对2011年度的卫星影像数据和第二次土地调查的土地利用现状数据库,对国土资源执法监察区域的土地利用变化情况进行了初步评价,取得了较好的效果。
Unmanned air vehicle （UAV） remote sensing system is a new way of rapid acquisition of high resolution image data. It is efficient, quick, accurate and economic. This paper introduced the composition and characteristics of UAV remote sensing system,designed a technical process for application of UAV remote sensing system in land and resources law enforcement and supervision, and made a testing analysis with the town of Wanzhi, Wuhu County as the aerophotographic area. After remote sensing image pretreatment, such as geometric correction, aerial triangulation encryption, image mosaicking and data precision analysis,and registration with landsat image data of 2011 and the second land survey＇s land utilization status database,it made an initial assessment of the land use change in the area under supervision and proved good in the result.
