METHOD FOR GENERATING HIGH DEFINITION MAPS, AND CLOUD SERVER AND VEHICLE

Provided is a computer-implemented method of generating a map, comprising the steps of: acquiring sensor-based data of a sensor unit of at least one vehicle and localization data related to a localization unit of the at least one vehicle; determining a first trail of the at least one vehicle using the localization data and a plurality of second trails of other vehicles using the sensor-based data; and aggregating the first trail and/or the plurality of second trails to generate aggregated trails in a grid map representation of the map.
