Virtualizing of a real scene for interactive virtual relighting

摘要

It is difficult to manipulate illumination conditions in a virtualized real environment if the environment has something with specular reflection. In this report, we present a method which virtualize a real scene including specular reflection for interactive virtual relighting. First we get a geometry of a real scene with a three-dimensional digitizer. We then estimate surface reflectances using a real image of the scene. Experiments show that a real scene can be successfully virtualized using the geometry and reflectances, and that illumination conditions can be interactively manipulated in the virtualized scene.
