ABSTRACT:
A three-dimensional model generating system obtains altitude information corresponding to a specified building region on a building/road map. On the basis of the altitude distribution in the building region, a plane corresponding to a connected subset of observation data is obtained. After all pieces of observation data are allocated to planes, the planes are interconnected to form a simply-connected polyhedron serving as a building model. Accordingly, individual pieces of building information, which are free from the effects of a building-located region, are generated on the basis of three-dimensional terrain information and a set of planes.
