A Study of Constructing Virtual Space by Real Image

Abstract

In this paper, we describe a scheme to make VRML data for 3D real objects such as buildings in a town by using some 2D photos. Our purpose is not to describe the details of each objects, but to realize relatively huge area in virtual space in a simple manner. We can construct a 3D virtual town on a WWW browsing software once some 2D photos are input. In walking through the virtual town, LOD(Level Of Details) for the textures is effectively used.
