Shadow based texture registration for 3D modeling of outdoor scenes

This paper presents a novel method for the registration of texture images with a 3D model of outdoor scenes. We pose image registration as an optimization problem that uses knowledge of the sun’s position to estimate shadows in a scene, and use the shadows produced as a cue to solve for the registration parameters. Results are presented on a controlled experiment and for a large scale model of an archaeological site in Sicily. Keywords 3D modeling · Texture registration · Shadows
