The application discloses a frame registration method and system of a solar extreme ultraviolet wave band imaging sequence, and the method comprises the following steps: acquiring observation data of a stationary orbit satellite in a solar extreme ultraviolet wave band and performing pretreatment, and extracting fitting circle parameters of a solar disc surface; performing imaging state judgment on the observation data; when the state is normal, performing state criterion branching on guide mirror measurement data; when the state is stable, performing thermal deformation correction and fusion processing based on the observation data; selecting a reference channel, performing high-precision calculation based on the fitting circle parameters, and performing north direction calculation and adjustment on the reference channel; calculating the center positions and the north directions of the remaining channels according to pre-calibrated inter-channel registration parameters, and realizing multi-channel registration; performing registration processing on the imaging sequence frame by frame, and outputting registration parameters of each frame image of each channel. The above method provides reliable support for the consistency and visualization of solar extreme ultraviolet observation data.
