基于严格成像模型的SPOT5 HRS反变换研究

INVERSE TRANSFORMATION OF SPOT5 HRS BASED ON THE RIGOROUS GEOMETRY MODEL

基于SPOT5 HRS严格成像模型,提出了一种新的严密的反变换算法,介绍了其求解过程,并利用某地区的数据验证了其可行性。

A new algorithm is proposed for the inverse transformation of the SPOT imaging model based on the rigorous geometry model. Then the process flow of the 5 HRS inverse method is presented in detail. The real data of certain region is used to test the algorithm. The result demonstrated that this algorithm is feasible, and its high accuracy shows the wide application prospect in image correction.
