This project investigates the possibilities and the potentials of applying spatial, temporal,
chrominance and luminance modulated digital light projectors in television studios for
enhanced live broadcasts and recordings. The key technical concept applies
synchronized projectors and cameras to display information that are visible (e.g., illumination
and special effects) or invisible (e.g., coded patterns for acquisition of scene depth and camera
pose, or dynamic direction information visible only to the moderator) in the
broadcasted/recorded video stream. Several engineering and computer science oriented
problems have to be solved throughout the project:
A soft- and hardware framework has to be
developed for synchronizing display- and capturing devices. New techniques for automatic
projector calibration, as well as for displaying image content in complex and dynamic
environments (not optimized for projections) have to be researched. Methods for offline and
online scene acquisition and camera tracking have to be evaluated, improved and adapted to
the proposed key concept. New projector-based and video-based illumination and
augmentation techniques will be implemented. The outcome of this novel technological
approach can open new possibilities for modern television studios.
