Zusammenfassung:The invention discloses a ground-control-point-free imaging method of a space optical camera. The method comprises the steps that two beams of positioning laser are arranged outside view fields on thetwo sides of the 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 is obtained according to inertia measuring data and the light spot position information for combination to obtain opticalaxis jitter data. Three pieces of pointing information are taken as optical axis pointing information of the optical axis of the space optical camera in the whole integration time period. And the mapping relationship between the real-time position of each light spot and a target position is used as the mapping relationship of the image to control the distortion data of imaging on a focal plane. 本专利公开了一种空间光学相机的无地面控制点成像方法,所
