ABSTRACT:
When creating three-dimensional electronic map data, three-dimensional modeling of a building is performed as follows without measuring height of the building. Firstly, a building is photographed and the photographing position and photographing parameters (camera direction, angle of view) are recorded. Secondly, in a virtual space prepared on a computer, a photograph is arranged so as to reproduce the state upon the photographing according to these data. In combination with this, a plan view of the building is arranged according to the two-dimensional map data. Thirdly, the plan view is moved in the height direction until it is overlapped with the photograph, thereby modeling the building. Thus, it is possible to realize three-dimensional modeling without measuring the height.
