摘要: 辐射地形校正是遥感影像解译的一个重要预处理步骤。利用高分辨率的DEM数据,提出了一种顾及微小地形的遥感影像辐射地形校正模型。该模型基于V型坡面光照模型,考虑了地表的非朗伯体反射的特性,模拟单个像素所包含的微小地形对像素辐射值的影响。利用多幅影像进行实验,结果表明:该模型明显优于传统校正模型。
关键词: 辐射地形校正微小地形非朗伯体反射V型坡面光照模型遥感    
Abstract: The radiant topographical correction is an important preprocessing for the interpretation of remote sensing imageries.A radiant topographical correction model is proposed with high-resolution DEM data by considering micro-terrain.The model simulates the effects of the micro-terrain units on pixels’ radiance.These micro-terrain units in a single pixel are used to describe topographical non-Lambertian reflectance characteristics based on V-slope illumination model.The experiments using several images have proved that the results of model that was applied in this study are better than that of the conventional correction methods.
Key words: Radiant topographical correction    Micro-terrain    Non-Lambertian reflectance    V-slope illumination model    Remote sensing
