AliceVision: a New Photogrammetry Pipeline in Visual Effects Production

Fabien Castan (Mikros), Yann Lanthony (Mikros), Benoit Maujean (Mikros)

This presentation will be based upon our experience accumulated by the production of CG environments, in order to extend or transform shooting sets and props. These solutions are the results of collaborative research with academic partners (Imagine lab in Marne la Vallée, Institut National Polytechnique de Toulouse, Czech Technical University in Prague, Simula in Oslo). In this context, we have built an open source software for 3D reconstruction, photomodeling and camera tracking.
During this presentation, we will explain the comprehensive photogrammetry pipeline, driven by the production needs. We will also unveil the corresponding algorithmic principles, based upon up-to-date Structure from Motion and Multiple View Stereo techniques. These concepts will be illustrated with Mikros production extracts, provided with our latest creations in feature films and commercials.
