Classification: CPC G | IPC G

Claim 11:
12. The image matching apparatus in accordance with claim 11, further comprising:
a rough matching part configured to
acquire first label information corresponding to the panoramic image of the at least one subspace in the 3D space;
acquire second label information corresponding to the 2D image of the at least one subspace in the 3D space; and
attain, 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 reconstruction part is further configured to perform, 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, 3D reconstruction on the panoramic image of the at least one subspace, for which the matching relationship cannot be created, and procure a projection image corresponding to the same panoramic image.
