无人机低空摄影测量在国家储备林基地检查验收中的应用试验研究

Application of Unmanned Air Vehicle Low-altitude Photogrammetry Technology in Inspection and Acceptance of National Reserve Forest Construction Project

检查验收是国家储备林基地建设项目成效管理与监督的必要手段。本文以广西国家储备林基地建设项目(一期)8个造林基地小班为研究对象,根据无人机低空摄影测量技术的正射影像成果,对比典型对坡勾绘成果和使用无人机数字测绘成果在林地小班面积和位置上的误差,分析无人机低空摄影测量技术在国家储备林基地建设项目检查验收中的应用。结果表明,无人机低空航测能满足检查验收精度要求,能减少外业时间和调查劳动强度,具有可行性和有效性。

The inspection and acceptance is a necessary means for the effectiveness management and supervision of national reserve forest base construction projects.This paper compared the errors in the area and position of the forest subcompartments between typical slope mapping results and the digital mapping results using UAV in eight afforestation subcompartments of Guangxi national reserve forest base construction project(Phase I),and analyzed the application of UAV low-altitude photogrammetry technology in the inspection and acceptance of the national reserve forest base construction project.The results showed that the UAV low-altitude photogrammetry technology could meet the requirements of inspection and acceptance accuracy,reduce field work time and investigation labor intensity,which was feasible and effective.
