摘要
对于普通影像纠正,传统的纠正模式是多项式纠正,对于高分辨率卫星遥感影像,则采取高精度的纠正方式。本文主要针对QuickBird影像,基于ERDAS软件,采用正射纠正,其校正模型加入了RPC轨道参数和DEM高程模型,从而大大提高了几何精度。
For the common image rectification,the traditional rectification mode is base on polynomial function.But in regarding to the high resolution satellite remote sensing image,it adopts high precision rectification mode.Aiming at the QuickBird image,based on ERDAS software,this paper discussed the Ortho-rectification with the correction model integrated with the RPC orbit parameters and DEM model.The method greatly enhanced the geometric accuracy of rectification.
