摘要
为快速、准确提取火龙果种植株数,以大疆Matrice 600 Pro六旋翼无人机搭载高光谱成像仪,获取关岭县上官镇乐安村火龙果种植基地的高光谱影像,通过影像处理,借助ENVI遥感影像处理软件结合ArcGIS空间分析软件,采用波谱角分类方法实现火龙果植株的提取。结果表明:基于无人机高光谱遥感技术对研究区火龙果植株数的提取精度为92.94%,利用该技术可实现快速、准确地提取火龙果种植株数,可为火龙果园精准管理提供一定的技术支撑。
The hyperspectral images of pitaya planting base in Le’an Village,Shangguan Town,Guanling County are obtained by Dajiang Matrice 600 Pro six-rotor UAV equipped with hyperspectral imager,and then pitaya plant number is extracted through spectral angle classification method based on image process,ENVI remote sensing image processing software combined with ArcGIS spatial analysis software to extract pitaya plant number rapidly and accurately.Result:The extraction accuracy of pitaya plant number in the study area is 92.94%based on UAV hyperspectral remote sensing technology.The technology can extract pitaya plant number rapidly and accurately,which provides a certain technical support for accurate management of pitaya.
