Zusammenfassung:The invention discloses an optical axis angle measuring method of a space optical camera. The method comprises the following steps: two beams of positioning laser are arranged outside view fields on the two sides of a space camera respectively, and then light spot position information of a first laser light source and a second laser light source on sub view fields of a camera focal plane at all sampling moments of an integration time period is measured; and incremental data combination is obtained according to the inertia measurement data and the light spot position information and optical axis jitter data is obtained. 本专利公开了一种空间光学相机的光轴角度测量方法,所述方法包括在空间相机的两侧视场之外各设置两束定位激光,然后测量来自第一激光光源、第二激光光源分别的在积分时间段的各采样时刻在相机焦平面的分视场上的光斑位置信息;并根据惯性测量数据和光斑位置信息得到增量数据组合得到光轴抖动数据。
