摘　　要：对遥感图像归一化地形校正模型的研究进行了回顾和总结。归一化模型包括二阶校正模型、地形均衡模型和坡度匹配模型3种方法。在云南省香格里拉县的TM遥感图像和DEM支持下,采用3种方法进行了校正对比实验。结果表明,3种方法中坡度匹配模型校正效果最好。对归一化地形校正模型今后可能的研究方向提出了建议。Research progress of normalization topographic correction model on remotely sensed data was reviewed and summarized. At present, the normalization model includes second stage correction model, topographic equalization model and slope-matching model. In order to prove reference to the relative research, a correction test was carried out to compare these methods, based on the TM remote sensing image and DEM of the Shangri-La region of Yunnan province. The results indicated that the correction effect of slope-matching model was the best. Suggestions on future possible research focuses of normalization topographic correction model were proposed.
