星载线阵CCD传感器的严格成像几何模型

Rigorous imaging geometry model of spaceborne linear array CCD sensors

影响高分辨率卫星影像定位精度的因素有很多,主要包括卫星轨道和姿态等动态参数、相机与卫星平台之间的几何关系以及相机内方位元素等静态参数,所有这些参数相互作用一起影响卫星影像的定位精度。对于星载线阵CCD影像的应用来说,首先要建立正确的传感器模型,以便恢复正确的物像间的关系。因此,本文试图建立能用于几何检校的、完备物理因素下的星载线阵CCD影像的严密传感器模型。

There are many factors that influence the orientation precision of high-resolution satellite images,which include dynamic parameters such as satellite orbit and attitude,static parameters such as interior orientation elements of camera and the spatial relationship between camera and satellite platform.All parameters would affect the orientation precision of satellite images.The first step of utilizing satellite images is to establish right sensor model.So,the rigorous imaging geometry model is presented in this paper.
