초록

We present a mobile augmented reality (MAR) system for in-situ 3D visualization of Mine Geographic Information System (MGIS) data. The system estimates user pose and overlays key MGIS layers—such as tunnel centerlines and field survey records—after converting them into lightweight GeoJSON, while cloud synchronization enables immediate access and updates on site. Our core technique converts a DEM into a mesh to build a 360° skyline look-up table (LUT); we then refine yaw by correlating this LUT (ZNCC/NCC) with the skyline extracted from the input image using SegFormer. With BVH indexing and a few-kilobyte LUT, the system achieves real-time updates at 30-60Hz on mobile devices. This vision-based yaw correction stabilizes the reference for MGIS 3D overlays even in mountainous areas where GNSS is unreliable, improving spatial understanding and operational efficiency for safety inspection and field surveys.
