Low-Cost 3D Spatial Data Construction in GNSS-Denied Tunnels Using Monocular Driving Video and HD Road Maps
This study presents a pipeline for constructing an HD-map-referenced three-dimensional point cloud in an absolute coordinate system from a single low-cost monocular driving video and demonstrates a practical low-cost route for constructing spatial data in GNSS-denied road sections.
