Data Fusion for Photorealistic 3D Models

This study aims at building photorealistic 3D models of realworld objects. We discuss the problem of combining a 3D textureless model obtained by 3D scanner, with optical images that provide textural information of the object. Recently, we have proposed a novel method to register an uncalibrated image pair to a 3D surface model. After registration, the images are mapped to the surface. However, as the images show different parts of the objects, partial overlapping textures can only be extracted from them. Combining the images into a complete texture map that covers the entire object is not trivial. We present a method to build photorealistic 3D models that includes algorithms for data registration and for merging multiple texture maps using surface flattening. Experimental results on real and synthetic data are shown.
