Exploitation of Stereophotogrammetrically Derived 3-D Wireframe Models to Produce Urban Simulations

Abstract

The U.S. Army Topographic Engineering Center (TEC) is investigating methods to incorporate photogrammetrically derived 3-D models of urban features into terrain visualization software, to facilitate the photorealistic simulation of urban environments. Ideally, cultural features such as buildings will be extracted automatically from digital imagery as 3-D wireframe models. Coordinates representing the vertices of the models are to be input to terrain visualization software running on a Unix workstation. Phototexture is to be applied to the models and to the underlying digital terrain elevation data in order to create photorealistic, 3-D urban environments for simulated fly- throughs. Urban features, 3-D Wireframe models.
