该文建立了一种星载红外多光谱扫描相机的成象模型,该模型描述了卫星在轨飞行过程中,红外相机的成象过程,同时包括了卫星姿态、轨道运动、地球自传、地球曲率和高斯投影的影响。利用该模型编制了仿真程序,制作了仿真图象,进行了仿真计算,对红外遥感图象的几何质量和配准精度进行了仿真分析。

In this paper, the photograph model of IR-MSS is presented. The model describes the scaner photograph, and includes the effect of the attitute of satellite, the orbit motion, the earth rotation, the earth shape and the Gauss map. The model is used to analyse and estimate the geometry quality and registration of the satellite IR-MSS image.
