Abstract

The present invention provides a road three-dimensional model modeling method based on a lane-level high-precision map, comprising the following steps: S10. Extract a road base map of a high-precision map according to remote sensing images and aerial photographs, and classify it as each layer ; S20. Extract the elevation data information at the important nodes of the road according to the local digital elevation model; S30. Import the road base map of the high-precision map into Sketchup, and create the basic framework of the 3D model of the road according to the elevation data information at the important nodes of the road ; S40. Create a buffer zone for the road signs in the high-precision map; S50. Import the created buffer zone into Sketchup to perform 3D modeling of the road signs; S60. Add other attribute information to the established 3D model. The present invention effectively combines remote sensing images, road information from actual aerial photography and terrain information reflected by the digital elevation model, which can reflect real road information.

Description

【Technical field】 [0001] The invention relates to the technical field of road three-dimensional modeling, in particular to a road three-dimensional model modeling method based on a lane-level high-precision map. 【Background technique】 [0002] With the development of GIS technology, computer technology and network technology, the realization of spatial digitization and virtualization to establish digital geospatial has become an important means for countries in the world to grasp the trend of high-tech and promote economic development, represented by digital cities, digital earth, etc. The digital geospatial plays an important role in land use supervision, spatial information management, urban system planning and management. The foundation of digital geospatial is the establishment of three-dimensional model of geographic data. The spatial data of road sections obtained by surveying and mapping methods basically belong to the 2D or 2.5D structure, which only expresses the p...
