An End-to-end System for Real-Time Point Cloud Visualization

By Hansjörg Hofer, Florian Seitner, and Margrit Gelautz


The growing availability of RGB-D data, as delivered by current depth sensing devices, forms the basis for a variety of mixed reality (MR) applications, in which real and synthetic scene content is combined for interaction in real-time. The processing of dynamic point clouds with possible fast and unconstrained movement poses special challenges to the surface reconstruction and rendering algorithms. We propose an end-to-end system for dynamic point cloud visualization from RGB-D input data that takes advantage of the Unity3D game engine for efficient state-of-the-art rendering and platformindependence. We discuss specific requirements and key components of the overall system along with selected aspects of its implementation. Our experimental evaluation demonstrates that high-quality and versatile visualization results can be obtained for datasets of up to 5 million points in real-time.
