Problems solved by technology

[0003] During the driving process of the vehicle, the real-time map of the parking lot can be built according to the collected data. When the vehicle passes the same road along different driving paths, two semantic elements for the road with different IDs will be generated in the map. Moreover, in the constructed map data, when there is a loopback, there will inevitably be repeated semantic elements, resulting in a map that is not the most streamlined map, and it is not easy to integrate between maps

Abstract

The embodiment of the invention provides a map processing method and device. The method comprises the steps of obtaining map data collected in the driving process of a vehicle; when a plurality of semantic elements forming a loop are detected in the map data, determining a plurality of target semantic elements collected for the same environment object from the plurality of semantic elements forming the loop; and according to the plurality of target semantic elements, carrying out duplicate removal on the map data. According to the embodiment of the invention, the duplicate removal of the map data is realized, and a simplified map is obtained.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method and device for map processing. Background technique [0002] The roads of underground parking lots are usually short and complicated. For unfamiliar underground parking lots, drivers will inevitably drive through the same section of road during driving. [0003] During the driving process of the vehicle, the real-time map of the parking lot can be built according to the collected data. When the vehicle passes the same road along different driving paths, two semantic elements for the road with different IDs will be generated in the map. Moreover, in the constructed map data, when there is a loopback, there will inevitably be repeated semantic elements, resulting in a map that is not the most streamlined map, and it is not easy to integrate between maps. Contents of the invention [0004] In view of the above problems, a map processing method and device for overcoming ...
