Assignee: RICOH COMPANY, LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 1:
2. The image matching method in accordance with claim 1, further comprising:
acquiring first label information corresponding to the panoramic image of the at least one subspace in the 3D space;
acquiring second label information corresponding to the 2D image of the at least one subspace in the 3D space; and
attaining, based on the first label information and the second label information, a matching relationship between the panoramic image of the at least one subspace and the 2D image of the at least one subspace,
wherein, the 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 includes
when the matching relationship between the panoramic image of the at least one subspace and the 2D image of the at least one subspace cannot be attained based on the first label information and the second label information, performing 3D reconstruction on the panoramic image of the at least one subspace, for which the matching relationship cannot be created, and procuring a projection image corresponding to the same panoramic image.
