Problems solved by technology

Since the navigation map does not realize accurate map display at the lane level of the road, it is impossible to obtain which lane the vehicle is in at the current position and which lane it should take during navigation, so it is impossible to realize lane-level navigation of the vehicle
At the same time, when generating a road map at the lane level, due to the size limit of the road map, the road map is generated and displayed according to the road map area (Tile). When making a map, it will result in incomplete road drawing or gaps in the road map area to be generated, which will affect the map display effect

Abstract

The invention discloses a map generation method and device for a road segment and a related system. The method comprises the steps of obtaining validity range information of each lane group unit in attribute information of a to-be-generated road segment from map data, according to the validity range information of each lane group unit, obtaining vehicle line vector data and attribute information of each lane group unit on the to-be-generated road segment from map data, determining the position of each lane group unit of the to-be-generated road segment, and generating modeling data of the roadsegment, and obtaining map drawing data according to the modeling data and drawing to generate a road map of the road segment. The generated road map of the road segment can display a complete map ofthe road segment in the road map area to which the road segment belongs, the phenomenon of lane line missing or lane butt joint gaps is avoided, lane-level map display of the generated road map is achieved, the map display fineness is improved, and lane information more conforming to a real road is displayed.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a method, device and related system for generating a road segment map. Background technique [0002] When the existing navigation map is displayed on the map, it only shows the basic single-line image of the road and the navigation route, but cannot show the lane condition of the road. Therefore, the display fineness of the road is insufficient. With the rapid development of the automobile industry, the car navigation system has become an indispensable and important link in the car driving assistance technology and automatic driving technology. Since the navigation map does not realize accurate map display at the lane level of the road, it is impossible to obtain which lane the vehicle is in at the current position and which lane it should take during navigation, so it is impossible to realize lane-level navigation of the vehicle . At the same time, when generating a road ma...
