摘    要:本文针对遥感图像数据量大、微机几何纠正速度慢的问题,提出了一种微机遥感图像几何纠正快速算法。该算法采取了行列分离多项式快速运算、自动优化分块分配内存、多波段同时处理等措施,大大提高了运算速度,并且对任意大图像可一次处理,无需分块,使微机遥感图像几何纠正方法完全达到实用要求。文中阐述了算法的技术细节,介绍了算法在微机上的实现和其速度指标。

关 键 词:遥感图像  几何纠正  快速算法  微机

Abstract:It is difficult to geometrically rectify remote sensing images in personal computer because of the large data. A PC-based fast algorithm of geometric rectification is presented to solve this problem. Three techniques are adopted in the algorithm: (1) fast calculating the polynormal by separating column items from rows; (2) accessing optimal rectangle sub-image according to the allocated computer memory; (3) processing all bands simultaneously. These techniques make the algorithm fast and suitable for images with any size. The implementation and performance of the algorithm are also discribed in this paper.
Keywords:remote sensing image  geometric rectification  fast algorithm  personal computer
