摘　　要：针对目前已有无人机影像处理软件不支持高光谱影像预处理,及低版本遥感图像处理平台(ENVI)批量化处理数据困难的问题,研究了利用交互式数据语言(interactive data language,IDL)与无人机遥感图像处理软件(PIE-UAV)相结合进行无人机高光谱影像处理的方法。首先,使用IDL实现影像预处理,包括影像配准、影像白板校正。其中,影像配准阶段包含单波段影像配准、配准后影像外扩、多波段合成以及影像裁切等步骤。其次,使用PIE-UAV进行影像正射纠正,使用ENVI软件进行影像镶嵌。实验结果表明,该方法能够得到色彩过渡均匀且满足要求的拼接高光谱影像。Aiming at the problems that the existing unmanned aerial vehicle(UAV)image processing software does not support hyperspectral image preprocessing,and the low version remote sensing image processing platform the Environment for Visualizing Images(ENVI)is difficult to process data in batches,The method of hyperspectral image processing for UAV using interactive data language(IDL)and UAV remote sensing image processing software pixel information expert unmanned aerial vehicle(PIE-UAV)was studied.Firstly,IDL was applied to realize image preprocessing,including image registration and image whiteboard correction.Among them,the image registration stage includes single band image registration,image expansion after registration,multi band synthesis and image cutting.Secondly,PIE-UAV was used for orthophoto correction,and ENVI software was utilized for image mosaic.The experimental results showed that this method could obtain the mosaic hyperspectral images with uniform color transition and meet the requirements.
