Title:
SEMANTIC MAP UPDATING METHOD, PATH PLANNING METHOD, AND RELATED APPARATUSES
Document Type and Number:
WIPO Patent Application WO/2023/131203
Kind Code:
A1
Abstract:
Disclosed in the present application is a semantic map updating method. The method comprises: acquiring at least one object point cloud which corresponds to the current collection region; constructing at least one first point cloud object according to the at least one object point cloud, and extracting corresponding first semantic information; acquiring from an original semantic map at least one second point cloud object and corresponding second semantic information; and according to the first semantic information and the second semantic information, obtaining a matching result of the at least one first point cloud object and the at least one second point cloud object, and then, according to the matching result, updating the original semantic map by using the at least one first point cloud object in a crowdsourcing semantic map. Further disclosed in the present application are a path planning method and related apparatuses. By means of the present application, new data is collected by means of crowdsourcing, and is matched with an existing semantic map for updating, thereby providing a guarantee for map matching and updating, and thus improving the map updating precision.
