| 摘 要： | QuickBird卫星遥感影像是目前世界上分辨率最高的商业卫星遥感影像(分辨率高达0.61m),遥感影像的几何纠正,是实现影像应用的前提。文章阐述了几何纠正原理与方法,对比地分析了高分辨率卫星影像常用的几何模型———赫尔墨特变换、仿射变换、线性变换和二次多项式变换。实验表明采用基于二次多项式变换,在平坦地区能获得相对较高的纠正精度,具备实际应用的可行性。

| Abstract: | The QuickBird satellite remote sensing images are the highest resolution images in commercial field in the world,of which the resolution reaches to 0.61 m.The application premise of remote sensing images is the geometric rectification.In this paper,the principles and results of four geometric rectification methods are described and compared,i.e.Helmert transformation,affine transformation,linear transformation and quadratic polynomial transformation.The research result shows that the quadratic polynomial transformation is a feasible one with relatively high rectification accuracy for flat areas. |
