Classification: CPC G | IPC G

Claim 0:
1. An image matching method comprising:
obtaining a panoramic image of at least one subspace in a 3D space and a 2D image of the 3D space, wherein, the 3D space consists of the at least one subspace, and when the 3D space is composed of a plurality of subspaces, the respective subspaces are not mutually overlapped;
acquiring, based on the 2D image of the 3D space, a 2D image of the at least one subspace in the 3D space;
performing 3D reconstruction on the panoramic image of the at least one subspace, and procuring a projection image corresponding to the panoramic image of the at least one subspace; and
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, and establishing an association relationship between the panoramic image of the at least one subspace and the 2D image of the at least one subspace between which the matching relationship is generated.
