3D immersive Underground Navigation
Résumé
In this paper, we describe a system for visualizing and exploiting 3D digital data of the Parisian sewer system (PSS). PSS presents a difficult working environment because it is subject to a certain number of risks: toxic gases and waste, biological risks such as viruses and pathogenic bacteria contained in wastewater. Certain areas of PSS are damp, unhealthy, encumbered with waste. In order to improve the working conditions of the sewers and usage of the network in the context of the research for a reduction on exposures to health and safety risks, we developed such system aiming to do the visualization and exploitation of 3D PSS data. Our system allows sewer operators to gather data, information for observation, direct inspection, indirect monitoring and reporting to assess the condition of such sewer system.
