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.

Claim (Index 1):
A method for creating a lane-accurate occupancy grid map for lanes, the method comprising in at least one mobile device:\n capturing an image sequence of an environment of the at least one mobile device by at least one camera, identifying and classifying objects in the captured image sequence by an evaluation unit, determining object positions of the objects relative to the at least one mobile device by the evaluation unit, defining a section in the environment, the section having a predetermined size and predetermined boundaries, assigning the identified and classified objects to the determined object positions in the defined section, determining a lane present in the section by the evaluation unit, transmitting object information and the object positions of the identified and classified objects, section information relating to the defined section, lane information and an item of time information to a map creation device by a transmitting device, repeating the preceding operations to define further sections of the environment, wherein in the map creation device:\n receiving the object information and the object positions, the section information, the lane information and the time information for each of the sections from the at least one mobile device, \n comparing the individual sections with one another based on the object information and object positions, the section information, the lane information and the time information, \n joining the sections of the at least one mobile device at their respectively adjacent boundaries, \n merging the joined sections of the at least one mobile device to form a digital map, and \n determining a current lane occupancy for lanes in sections of the digital map by assigning the at least one mobile device to the determined lane in the corresponding section based on the object information and object positions, section information, the lane information and the time information received from the at least one mobile device.
