论文首先介绍了图像几何畸变的产生，并通过分析得到几何畸变的校正算法，通过三维投影变换把系列航空图像变换为同一坐标系(地面坐标系)下的几何畸变校正图像。 - Abstract : according to the fragment warhead of the missile , we propose dynamic characteristic of fragment dispersion in different reference frames , calculate dynamic distributing density function in earth reference frame and missile reference frame , and point out the dispersion section of the warhead is different from the dynamic distributing density in earth reference frame and missile reference frame
文摘:以某型防空导弹的破片杀伤式战斗部为例，分析了在不同坐标系中的破片动态飞散特性，分别计算出在地面坐标系和弹体坐标系中破片的动态飞散密度函数，指出在不同的坐标系中战斗部的飞散区和飞散密度不同。
