Abstract

Recently, the use of three dimensional computer models has greatly increased, in part due to the availability of fast, inexpensive hardware and technologies like VRML-ready Internet browsers. These models often represent objects in real world scenes and are typically built by hand using CAD software, an error-prone and time consuming process. The paper outlines a simple and efficient method based on passive stereo imaging techniques by which these models may be acquired, processed and utilized with little effort. The described method extracts the 3D geometrical data from the stereo images, for the purpose of creating realistic 3D models. The approach uses calibrated cameras
