卫星图像都是在动态情形下获取的。瞬间曝光获取的图像投影性质等同于透视投影。针对卫星动态获取的正图像,建立其平面透视投影,利用矢量解法研究其正反解变换和星下点坐标计算方法,最后给出算例。
All the satellite images are obtained dynamically. The image which obtained in fast exposal way has the projection characteristic of perspective projection. We discuss the elevation images of satellite which is taken dynamically, establish its perspective projection, and also research its direct and inverse transformation and the arithmetic of the ground track coordinates, finally, give a computational case.
