Research on the Production Method of High-definition Road Maps Combining Various Measurement Technologies
This paper selects the connection section between urban roads and expressways as the experimental object,uses a 3D laser scanning vehicle equipped with a panoramic camera to obtain road information,realizes taking the vehicle point cloud data as the base map,combines the vector data of road thematic elements such as points,lines,and surfaces extracted semi-automatically from pano-ramic photos,and uses the oblique photogrammetric technology to establish a 3D model of local areas including toll stations,service areas,and obtain vector data. The road lane vector data obtained by various measurement techniques are registered and fused to a-chieve the construction of high-definition road map. The test results show that various measurement techniques can give full play to their respective measurement advantages,and can efficiently build high-definition road maps,meeting the measurement accuracy re-quirements of L3 level of high-definition raod lane map static data.
