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

Abstract

The invention discloses a road map generation method, device and a related system. The method comprises the following steps of: determining a to-be-generated road map area according to current position information, obtaining all road line segments of the to-be-generated road map area from the map data, for each road line segment, determining the position of each lane group unit of the road line segment, and sequentially connecting lanes of each lane group unit into a whole according to the walking direction to obtain lane modeling data of the road line segment, and obtaining map drawing data according to the lane modeling data and drawing to generate a road map. When a road map is generated, the lanes of each lane group unit of a road line segment of a road map area are connected into a whole, the lane line data of each lane group unit can be acquired, and the lane lines can be drawn during map drawing, so that lane-level map display of the generated road map is realized, 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 road map generation method, device and related system. 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 . Contents of the invention [0003] In view of the above...
