摘　　要：由于CCD航空成像系统属于全影扫描成像,因此它的计算与全景相机基本相同,但由于CCD航空成像系统作用于高高度、远斜距条件下,这时再用一般直角三角形的关系进行计算会产生较大的误差,所以,对其参数的计算可用平面几何的方法,计入地球曲率的影响进行计算.For the reason that the system of aviation CCD imaging is one kind of all orientation scan imaging system, the calcuation for its parameters is the same as all orientation camera.But for the reason that CCD aviation imaging system works under the condition with hign altitude and far inclined distance,if we calculate its parameters by right triangle relationship, the difference may be great.So,to calculate its parameters, we can use methods belonging to plane geometry, with the consideration of the effects from earth curvature.
