资源三号卫星影像纠正的方法研究

Research on Correction Method of ZY-3 Satellite Image

影像的应用前提是影像处理,大气校正可消除大气和光照等因素对地物发射的影响。在此基础上,介绍几种常用的几何纠正方法,可消除系统和非系统因素引起的影像几何变形。本文通过对资源三号卫星的基本参数信息和相对应影像数据特点的介绍,先通过大气校正,校正后的影像分别使用几何纠正的几种方法,并通过各种方法的计算量、实用性以及相应的精度,对比分析各种方法在处理这种数据时的优越性。

Image processing is the imaging applications on the premise,according to the Imaging Pretreatment:atmospheric correction,can eliminate atmospheric and illumination other factors on the surface features emission the impact of;on this basis,introduce of several commonly used Geometric Correction Method,can eliminate system and the non-system caused by factors image Geometric deformation.Based on ZY-3 basic parameters of the satellite image data corresponding to information and knowledge of the characteristics,first through the atmospheric correction,the corrected image geometric correction were used several methods,and through a variety of methods of calculation,and the corresponding accuracy of practicality,comparative analysis in various ways to handle the data superiority.
