| 摘 要： | 采用不变点群法(temporally invariant cluster,TIC),由两时相影像的NDVI点密度图确定两个TIC中心并建立辐射归化处理方程,对影像的NDVI进行相对辐射归化处理。与其它辐射归化处理方法相比,该方法简单、有效且精度高,对轻微的植被物候变化敏感且影像不变特征点较少时也能进行辐射归化处理,可有效应用于土地利用/覆盖、植被物候及景观等变化监测。

| Abstract: | Radiometric consistency is hard to maintain between separate images due to variations in atmospheric conditions,solar illumination angles,sensor characteristics and sensor view angle.Therefore,radiometric corrections are often performed on multi-temporal imagery to any or all of the variations.This article reports a new relative radiometric normalization technique of multi-temporal satellite imagery of the same terrain.In this study,image data in Xiamen area were acquired on March 4,2001 and March 26,2003(L... |
