Abstract

Mountainous road topography is complex and the environment is harsh, posing challenges for traditional surveying technologies, which face significant operational difficulties and insufficient accuracy. This paper focuses on high-precision mountain road mapping technology based on Unmanned Aerial Vehicles (UAVs) and Light Detection and Ranging (LiDAR). It explores the technical principles, system composition, and data processing workflow. Experimental verification demonstrates that this technology can overcome topographic limitations, acquire high-precision road point cloud data, and provide precise support for the planning, construction, and maintenance of mountain roads.
