Realistic 3D simulation of shapes and shadows for image processing

Abstract : This paper illustrates the cooperation between Image Processing and Computer Graphics. We present a new method to compute realistic 3D images of building or complex objects from a set of real pictures and from the 3D model of a real scene. We also show how to remove shadows from those pictures and how to simulate new lightnings. Our system allows the generation of synthetic pictures, with a total control over the position of the camera, over the features of the optical system, and over the solar lightning. We propose several methods to avoid most of the artefact which would be produced by a straghtforward application of our approach. At last, we propose a general scheme to use these pictures in order to design new optical systems and to test Image Processing algorithms, long before the building of the first physical prototype.
