Abstract
A method and an apparatus for processing high-precision map data, a storage medium and a device. The method includes: performing at least twice collection on map data along a target trajectory so as to respectively acquire at least twice original map data; recognizing an object in the original map data respectively, and extracting an object feature; matching the object feature in each of the original map data; considering an object with the matched object feature as a reference object; and performing fusion processing on each of the original map data. An object in original map data is recognized and an object feature is extracted, then the object feature in each of the original map data is matched and the object obtained after the matching is considered as a reference object, and the reference object is utilized to perform fusion processing on the original map data. In this way, a problem of offset of an object in a map image is solved, ghosting of the map image is removed, and a definition of the map image is improved.
