Abstract

The embodiment of the invention discloses a map updating method and device, equipment and a storage medium. The method comprises the following steps: in a navigation map of a vehicle in a driving state, determining a first point cloud data set of a virtual road sign in a virtual road scene; acquiring a second point cloud data set of a real road sign in a real road scene in which the vehicle runs; and updating the position information of the first point cloud data set in the navigation map based on the second point cloud data set to obtain an updated navigation map.
