Abstract: The embodiment of the invention discloses a high-precision map data processing method and a high-precision map data processing device. The method comprises the following steps of performing at least twice collection on map data along a target track so as to respectively obtain at least twice original map data; respectively recognizing objects in the original map data, and extracting object features; matching the object features in each original map datum; using an object with the matched object features as a reference substance; and performing fusion processing on each original map datum. The embodiment of the invention has the advantages that the objects in the original map data are recognized; the object features are extracted; the object features in each original map datum are further matched; the object obtained after the matching is used as the reference substance; and the reference substance is used for performing fusion processing on the original map data. The problem of offset of objects in a map image is solved; the ghost problem of the map image is solved; and the definition of the map image is improved.
