Abstract
Conventional mine site investigation has difficulties in fostering location awareness and understanding the subsurface environment; moreover, it produces a large amount of hardcopy data. To overcome these limitations, the UMineAR mobile tablet application was developed. It enables users to rapidly identify underground mine objects (drifts, entrances, boreholes, hazards) and intuitively visualize them in 3D using a mobile augmented reality (AR) technique. To design UMineAR, South Korean georeferenced standard-mine geographic information system (GIS) databases were employed. A web database system was designed to access via a tablet groundwater-level data measured every hour by sensors installed in boreholes. UMineAR consists of search, AR, map, and database modules. The search module provides data retrieval and visualization options/functions. The AR module provides 3D interactive visualization of mine GIS data and camera imagery on the tablet screen. The map module shows the locations of corresponding borehole data on a 2D map. The database module provides mine GIS database management functions. A case study showed that the proposed application is suitable for onsite visualization of high-volume mine GIS data based on geolocations; no specialized equipment or skills are required to understand the underground mine environment. UMineAR can be used to support abandoned-mine hazard site investigations.
Highlights
Augmented reality (AR) is an emerging technology that creates a type of virtual environment by extending the user’s perception with virtual information [1]
We developed a mobile tablet application called Underground Mine Augmented Reality (UMineAR)
This paper describes the development details and functions of the UMineAR application
Summary
Augmented reality (AR) is an emerging technology that creates a type of virtual environment by extending the user’s perception with virtual information [1]. Mobile AR development in recent years has been advanced by the evolution of information and communication technology, such as sensors (e.g., the global positioning system (GPS) and inertial sensors), embedded microsystems, wireless communication, and mobile devices (e.g., tablet PC and personal digital assistant) [2,3,4]. Development progress in mobile AR systems with tablet capabilities has fostered novel approaches to representing and interacting with geospatial data. AR technology can potentially provide significant advancements in underground resource development and facilities management, as well as in mobile gaming, tourism, and advertising
