| 摘 要： | 以星载Hyperion L1R高光谱影像数据为研究对象,详细分析了完整的影像预处理流程及相关算法,包括利用像元灰度斜率阈值法、波段全局归一化法和归一化差值植被指数法实现影像的坏线修复、垂直条纹去除以及潮滩研究区的地物分离.然后结合FLAASH大气校正处理以及几何校正处理,得到潮滩地表真实光谱反射率影像.研究结果表明,该流程为潮滩地物进一步的高光谱定量遥感解译提供了必要的技术支撑.

| Abstract: | EO-1 Hyperion L1R data for hyperspectral image are the studied subject in order to introduce in details the entire flowchart and the related computational algorithms of the data-preprocessing for the imagerey. The introduction includes PGST method (pixel grey-scale slope threshold method), BGNM method(band global normalization), and NDVI method, which are utilized to revise the bad lines in the image, remove the vertical stripes, or seperate the tidal flat from the other characterized objects. Finally FLAAS... |
