摘　　要：卫星发射及在轨飞行中,环境变化会影响三线阵CCD相机的内方位元素。实际上使相机成为不符合摄影测量定义的相机,导致由经典摄影测量原理推导的有关公式应用受到影响。因此,将变化了的内方位元素规范为正视相机的x坐标为零的内方位元素系统,而此系统的其他参数则作为EFP法反解内方位元素的待求参数,并给出了计算数学模型及模拟计算结果。The inner orientation elements of the three-line-array CCD camera are affected by the change of the cir cumstance during the satellite＇s launching and flying on the orbit. In fact, this makes the camera fall short of the camera defined by photogrammetry and causes the application of some formulations deduced by traditional photo grammetry to be affected. This paper standardizes inner orientation elements system from the changed inner ori entation elements to inner orientation elements with x coordinate of the vertical camera equaling zero and considers the other parameters of this system as the parameters to be computed while calculating the inner orientation ele ments using EFP method with ground control points. Then the mathematics model and the calculating results with simulation data are given.
