| 摘 要： | 像移会使图像质量退化,分辨率下降,为此必须对像移进行补偿。文章从空间相机像移补偿的角度出发,建立了卫星遥感中偏流角和速高比的概念;通过坐标转换推导出了卫星在星下点、侧摆、俯仰摄影模式下偏流角和速高比的计算公式,从而可考虑对所产生的像移进行补偿。

| Abstract: | Image motion will lead to degradation of image quality and reduction of resolution,which therefore must be compensated.The concepts of veer angle and velocity-height ratio are specified from the point of view of image motion compensation of space camera.The veer angle and velocity-height ratio computation formulas for space camera in roll and pitch attitudes are derived using coordinates transformation.As a result,the compensation of the image motion can be considered. |
