Abstract

In the last two years Augmented Reality (AR) has experienced a breakthrough thanks to cheaper hardware and a strong industry commitment. AR scope is becoming increasingly broad reaching areas other from entertainment or ed- ucation. In the field of management of urban facilities, this technology allows virtual access and interaction with hidden underground elements. This paper presents a new approach to enable AR in mobile devices such as Google Tango, which has specific capa- bilities to be used outdoors. The main objective is to provide full functionality in the life-cycle management of subsoil in- frastructures through this technology. This implies visualization and interaction, but also editing, deleting and insert- ing elements to complete the set of CRUD operations ubiquitously. For this, a topological data model for 3D data has been designed. Problems normally associated with exact location and orientation in AR are addressed using an innovative and ef- ficient technique. In this, no additional markers or hardware are needed, which allows performing direct and on- site actions in any part of the city. Similar functionality has also been implemented in a non-ubiquitous way to be sup- ported by any other device through Virtual Reality (VR). The tests have been performed using real data of the city of Jae´n (Spain).
