Embodiment 1
[0090] Embodiment 1 of the present invention provides a method for generating a map of road segments in a road map area, wherein the road segment to be generated includes lane group units crossing the road map area, and the lane group units spanning the road map area are Lane group units of two adjacent road map areas, the process refers to figure 1 shown, including:
[0091] S101: Obtain the validity range information of each lane group unit in the attribute information of the road segment to be generated from the map data;
[0092]S102: According to the validity range information of each lane group unit, obtain the lane vector data and attribute information of each lane group unit on the road segment to be generated from the map data;
[0093] S103: Determine the position of each lane group unit of the road segment to be generated, and generate modeling data of the road segment;
[0094] S104: Obtain and draw map drawing data according to the modeling data to generate a ro...
Embodiment 2
[0184] Based on the same inventive concept, an embodiment of the present invention also provides a road segment map generating device, which can be set in a navigation server or a navigation terminal, and the structure of the device is as follows Figure 9 shown, including:
[0185] The first acquisition module 101 is configured to acquire vehicle line vector data and attribute information of each lane group unit of the road segment in the first road map area from map data;
[0186] The second acquisition module 102 is used to obtain the lane group unit crossing the road map area in the adjacent second road map area from the map data according to the feature index information in the attribute information of the lane group unit crossing the road map area The vehicle line vector data and attribute information;
