Depth cameras are increasingly used for tasks such as 3-D reconstruction, user pose estimation, and humancomputer interaction. Depth-camera systems comprising multiple depth sensors require careful calibration. In addition to conventional 2-D camera calibration, depth correction for each individual device is necessary. In this paper, we present a new way of(More)
Systems for multi-camera telepresence utilizing Large High-Resolution Displays (LHRDs) face the problem of generating large amounts of dynamic data. These data have to be processed at the local capture site, aggregated from different nodes locally, possibly processed again, transmitted to a remote site, and processed further. Since resources are limited a(More)
We present a distributed dataflow-based camera library design. It is tailored to the special needs of distributed acquisition and rendering telepresence systems with inhomogeneous camera arrays. We discuss a variety of design decisions: choice of dataflow concept, memory management, camera interface abstraction and important built-in functionality.
Telepresence systems use 3D techniques to create a more natural human-centered communication over long distances. This work concentrates on the analysis of latency in telepresence systems where acquisition and rendering are distributed. Keeping latency low is important to immerse users in the virtual environment. To better understand latency problems and to(More)
