Abstract

A method for creating a lane-accurate occupancy grid map for lanes. In at least one mobile device, an environment is sensed by a camera and evaluated by an evaluating unit. The evaluating unit defines a section in the environment and determines a lane in the section. Objects in the environment or in the section are also detected and classified by the evaluating unit. The object information, section information, time information, and the lane information are transmitted to a map-creating device, which creates a lane-accurate occupancy grid map for the lane therefrom. The lane-accurate occupancy grid map can be transmitted back to the mobile device. Also disclosed is an associated system.
