VIDENTE - 3D Visualization of Underground Infrastructure using Handheld Augmented Reality

Introduction This chapter outlines a research project called Vidente following the vision of registered 3D visualization of underground networks on handheld devices in real-time. Towards this aim, technology from interdisciplinary fields such as computer graphics, augmented reality, geographic information systems (GIS) and satellite navigation needs to be addressed. We highlight aspects of the Vidente system targeted on water systems operated by utilities from the water supply sector, which are already completely relying on their geo-databases for day-today operation of their assets. However, there is a noticeable gap between desktop GIS technology available in the office and access to this information in the field. To fill this gap, we propose to provide field workers with an intuitive three-dimensional visualization of the local underground network infrastructure using outdoor handheld augmented reality (AR) as depicted in Figure 1. The focus is on a next-generation mobile GIS system for utilities as well as telecommunication companies, supporting mobile workforces in the complete life cycle of water infrastructure, thus revolutionizing traditional planning, operation, maintenance, on-site inspection, fault management and decision-making. The project significantly advances mobile GIS in water engineering. Moreover, common field tasks concerning maintenance and operation are accomplished more efficiently while reducing unintended damage and increasing general safety on site. The system is intended to equip professionals, practitioners, water resources engineers, managers and decision makers working in water related arenas, utilities from the water sector, water boards and other government agencies with available information and advanced information technology tools to assist in on-site applications to geohydrological and environmental problems of urban waters.
