Abstract:

Traditional film and broadcast cameras capture the scene from a single viewpoint, while important creative parameters such as the camera position and orientation, the depth of field, and the three-dimensional (3D) parallax when using a 3D camera rig are burned into the footage during acquisition.

To realize artistic effects such as the matrix or the vertigo effect with traditional cameras is a complex task that requires skilled personnel. For the vertigo effect, the scene needs usually to be shot multiple times until the best combination of zoom corrections and dolly movement is found.

Against this background, a system is presented that allows capturing the light field of a live action scene and thus offers full creative leeway of changing camera paths and orientation, as well as setting the focal plane in post-production. In contrast to previous approaches, the handling of the involved acquisition system is compact and thus suitable for on-set operation.

Together with the German Stuttgart Media University HDM , the Computational Imaging group at Fraunhofer IIS set up a project to evaluate and demonstrates the potential of shooting with multi-camera arrays and light-field processing. Details about the test production, the underlying camera setup and post-production workflow are given in the presentation.

About the presenter:

Frederik Zilly is head of the Computational Imaging and Algorithms group in the Moving Picture Department of Fraunhofer IIS in Erlangen, Germany. He received a diploma degree in physics from Free University of Berlin, and a Ph.D. degree in Computer Science from Technical University Berlin. Before joining Fraunhofer IIS , he was scientific project manager in the Immersive Media and 3D Video group in the Image Processing Department at Fraunhofer HHI in Berlin where he was involved in several German and European research projects related to 3DTV. In this function was mainly responsible for the development of the stereoscopic analyzer (STAN) and coordinated the activities of the Fraunhofer HHI concerning the European research project MUSCADE project. Zilly has been honored for his work on the assistance system STAN (Stereoscopic Analyzer) with the Award for Outstanding Merit in Young Scientists, the Rudolf Urtel Prize 2011. He serves as reviewer for different international conferences and journals. His research focus lies in multi-camera image processing algorithms.
