AI Technical Summary

Problems solved by technology

However, in the process of 3D modeling the existing road data, it is necessary to discard some detailed data in the existing road data, such as the road turning angle data, resulting in a large deviation between the road in the loaded electronic map and the actual road.

Abstract

The invention discloses a road three-dimensional visualization modeling method and device, which relate to the technical field of road visualization and are used to improve the accuracy of roads in loaded electronic maps. The three-dimensional road visualization modeling method includes: presetting vector road classification data; processing the vector road classification data, rendering the processing results, and completing road three-dimensional visualization modeling. The road three-dimensional visualization modeling device is used to implement the road three-dimensional visualization modeling method proposed in the above technical solution. The road three-dimensional visualization modeling method and device provided by the present invention are used for loading roads in electronic maps.

Description

technical field [0001] The invention relates to the technical field of road visualization, in particular to a road three-dimensional visualization modeling method and device. Background technique [0002] The electronic map is a very common travel navigation tool in people's daily life. People can easily use the electronic map to obtain the required navigation scheme, which brings great convenience to the travel of the user. [0003] At present, the road information displayed in the electronic map is three-dimensional modeling of the existing road data to obtain a three-dimensional road model, and then the three-dimensional road model is loaded on the web page through the map interface program (hereinafter referred to as map API), so that the loaded The roads in the electronic map can be displayed in any perspective in the three-dimensional direction, so that users can roam the roads in the three-dimensional space. However, in the process of 3D modeling the existing road da...
