Patent ID: 7149346

Claim:
A three-dimensional database generating system comprising; at least a satellite equipped with functionality for stereo photographing a subject region as it orbits around the earth maintaining a specified height; and a data analysis means for analyzing a pair of stereographic images photographed by said satellite to generate a three-dimensional database, wherein said data analysis means comprises: a stereo processing means for calculating, based on said stereographic pair images photographed from said satellite, primary height data of objects included within said images; a outline extraction processing means for extracting outlines of said objects from said stereographic pair images photographed from said satellite; a correction processing means for correcting said primary height data calculated by said stereograph processing means by using existing information on height and said outlines of said objects extracted by said outline extracting processing means and outputting that as height data; an orthogonal transform processing means for performing orthogonal projection transform on one image of said stereographic pair images photographed from said satellite by using height data output from said correction processing means; a polygonization processing means for three-dimensionally polygonizing said objects by using the outlines of said objects extracted by said outline extraction processing means and height data output from said correction processing means; and a texture processing means for applying said image that has orthogonal projection transformed by said orthogonal transform processing means to said objects three-dimensionally polygonized by said polygonization processing means.
