WebDec 23, 2024 · 实验内容:ENVI软件中高光谱图像预处理模块下的图像快速大气校正。快速大气校正工具(QUick Atmospheric Correction, QUAC)自动从图像上 收集不同物质的波谱信息,获取经验值完成高光谱的快速大气校正。它得到结果 的精度近似FLAASH或者其他基于辐射传输模型的+/-15%。 WebFLAASH is a better choice for these scenes. QUAC performs best when the imagery is uniformly illuminated, such as clear-sky conditions or when airborne sensors fly under complete cloud cover. If the imagery contains clouds and cloud shadows, you can mask out the clouds and shadows.
