摘要: 根据卫星图像摄影过程,建立了图像质量评价的数学模型。该模型包括:整机侧视和反射镜侧视两种相机侧视方案,姿态运动、轨道运动、地球自转、地图投影等因素对卫星图像几何质量的影响。并在计算机上分析了图像的几何质量,提出了几何校正方法,为遥感卫星设计提供了有价值的参考。

Abstract: simulation model of Satellite-Borne Image photograph is set up,two camera sideview methods,attitude motion,orbit motion,Earth rotation,map projection and so on are included in this model.Then,the Satellite-Borne Image geometric quality was analyzed and simulated by using a computer, a geometric correction method is presented in this paper.It is a valuable reference for satellite design.
