Abstract
To address issues such as low efficiency and insufficient accuracy in data acquisition,as well as high costs associ-ated with traditional measurement methods during the digitization process of highway facilities,this paper proposed a solu-tion based on a vehicle-mounted mobile measurement system.By taking a national highway test area in Jinan City as the object,the VSurs-E mobile measurement system,integrated with a laser scanner,integrated navigation system,and pan-oramic camera,was employed to achieve high-speed dynamic acquisition of multi-source point cloud and imagery data for the highway and surrounding features.Through technical processes including field data acquisition,integrated navigation computation,point cloud quality correction,and element extraction of highway facilities,high-precision vectorized model-ing of road networks,markings,signs,and other facilities was completed.Experimental results demonstrate that the vehicle-mounted mobile measurement system boasts high efficiency,high precision,and three-dimensional visualization advan-tages,providing reliable technical support for the full-cycle digital management of highway facilities and promoting the trans-formation of highway asset management towards intelligence.关键词
