Abstract

The embodiment of the invention provides a map generating method and device as well as equipment and a storage medium. The map generating method comprises the following steps that a first map is acquired, wherein the precision of the first map is accurate to a lane; multiple sections of lanes leading to the target direction in the first map undergo fitting to generate a target road line; the target road line is searched in a navigation map, and road information related to the target road line is obtained from the navigation map; and the road information is added into the first map to generatea high-precision map. According to the embodiment of the map generating method and device as well as the equipment and the storage medium, the production difficulty of the high-precision map can be reduced, the manufacturing efficiency of the high-precision map can be improved, and the cost can be saved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of high-precision maps, and in particular, to a method, device, device, and storage medium for generating a map. Background technique [0002] Autonomous driving technology needs to rely on high-precision maps. Vehicles can drive based on the road information in high-precision maps. Therefore, the road information in high-precision maps needs to be very accurate to ensure the safe driving of unmanned vehicles. [0003] Compared with traditional navigation maps, high-precision maps have just started, with less map data, and a large amount of road information (such as speed limit information, road names, etc.) needs to be collected to produce high-precision maps, which leads to the workload of making high-precision maps Very large, resulting in a long period for the high-precision map to go online. Contents of the invention [0004] Embodiments of the present application provide ...
