  • This paper proposes a registration method based on object-space positioning consistency for satellite multi-spectral images.The method includes two steps: restoring the precise band-to-band relative geometric imaging relationship by adopting a method similar to relative orientation,and realizing automatic registration with sub-pixel accuracy without image-matching using the constraint conditions of object-space positioning consistency of the homologous image points.The method uses a rigorous geometric imaging model as the rectification model,achieving true geometric registration and is theoretically strict.The results,furthermore,have no relationship with the image quality.In our experiment,ZY3 satellite multi-spectral images are tested to demonstrate the feasibility and correctness of our method.This method has been successfully applied in the satellite image pre-processing software.
