Claim 4:
5. The image matching method in accordance with claim 1, wherein, the attaining, based on the projection image of the at least one subspace and the 2D image of the at least one subspace, a matching relationship between the panoramic image of the at least one subspace and the 2D image of the at least one subspace includes
performing shape matching on the projection image of the at least one subspace and the 2D image of the at least one subspace so as to obtain a shape matching result, and establishing, based on the shape matching result, a matching relationship between the projection image of the at least one subspace and the 2D image of the at least one subspace; and
acquiring, based on the matching relationship between the projection image of the at least one subspace and the 2D image of the at least one subspace, a matching relationship between the panoramic image of the at least one subspace and the 2D image of the at least one subspace.
