Satellite-ground consistency control method and system for distributed optical imaging system

The invention discloses a satellite-ground consistency control method and system for a distributed optical imaging system. The method comprises the following steps: establishing a distributed optical system on the ground; carrying out ground optical adjustment to obtain relative positions and attitude information parameters of the master satellite and the slave satellite when the distributed optical system successfully images; performing a simulation test of an on-satellite working state on the installed and adjusted distributed optical system to obtain a force-light coupling model; in-orbit detection is carried out, and an actual target fixed star image and parameter information are obtained from the time when the target fixed star enters the field of view of the distributed optical system to the time when the target fixed star walks out of the field of view of the long-focus camera of the distributed optical system; the parameter information is substituted into the force-light coupling model to output a mod
