摘要
本文提出了遥感图象几何校正快速算法,该方法不仅能够最大限度地减少坐标变换中的冗余计算,而且较好地解决了常规递推法所存在的误差传递和误差积累等问题。同时,在利用最小二乘原理对多项式进行拟合的基础上采用了扰动算法,这就更加有效地降低了控制点上的拟合误差,提高了几何校正精度。
This paper puts forward a new fast algorithm in geometric correction for remote sensing image. Making use of this algorithm, the verbose operations in coordinate transform can be reduced to minimum and the problems of error trans-mission and error accumulation in conventional recurrence methods can be solved well enough. Meanwhile, based on the polynomial fitting with the least squares principle, the disturbance algorithm has been adopted. The result is that the fit-ting errors at control points have been reduced more effectively and the precision of geometric correction has been improved.
