Patent ID: 7218318

Claim:
A server for improving a three-dimensional air excursion, comprising: a three-dimensional image database for storing a three-dimensional image data including a three-dimensional object identification for uniquely identifying a three-dimensional object data produced by a stereographic processing of photograph data with a correspondence of the three-dimensional image data and a ground surface position; a structure database for storing a structure identification for uniquely identifying a structure, a physical position of the structure on a ground surface and a three-dimensional object identification corresponding to the structure, in corresponding state; and a structure identification finding means for calculating the physical position of the structure corresponding to the three-dimensional object identification included in the three-dimensional image data from the ground surface position corresponding to the three-dimensional image data, specifying the structure identification in the structure database on the basis of the calculated physical position of the structure and the physical position of the structure in the structure database, and storing the three-dimensional object identification corresponding to the structure with a correspondence of the specified structure identification and the three-dimensional object identification in the structure database.
