Abstract

The embodiment of the invention provides a map updating method and device, and the method comprises the steps of carrying out the vectorization of collected point cloud data, and obtaining point cloudvector data which is vector data corresponding to the point cloud data; obtaining a plurality of homonymy points according to the original map data and the point cloud vector data, the original map data being vector data; and updating the original map data according to the homonymous points to obtain updated map data. According to the embodiment, the homonymous points are obtained according to the original map data and the point cloud vector data, and the original map data and the point cloud vector data are vector data, so that the homonymous points can be efficiently and conveniently determined, the original map data is updated according to the homonymous points, and the map updating efficiency can be effectively improved.

Description

technical field [0001] Embodiments of the present invention relate to computer technology, and in particular to a method and device for updating a map. Background technique [0002] With the continuous progress and development of vehicle automatic driving technology, high-precision maps with detailed map elements are also widely used as one of the core technologies of automatic driving. In order to ensure the safety of automatic driving, it is usually necessary to continuously update high-precision map data. [0003] At present, when updating high-precision maps, point cloud data is usually obtained by collecting the site, and features are extracted from the point cloud data to perform similarity matching to generate points with the same name. The map data is registered and differentiated to obtain the difference between the old and new map data, and then the difference is updated. [0004] However, extracting features from point cloud data to generate homonymous points is ...
