METHOD FOR ASCERTAINING IN A BACKEND, AND PROVIDING FOR A VEHICLE, A DATA RECORD, DESCRIBING A LANDMARK, FOR THE VEHICLE TO DETERMINE ITS OWN POSITION

摘要

A vehicle takes and evaluates an image of the surroundings of the vehicle. If the result of the evaluation is that the image possibly contains a static object that could be suitable as a landmark, then the image and a position of the vehicle ascertained by the vehicle at the location at which the image is taken are transmitted to a data processing station. Image analysis of the received image allows the data processing station to establish whether the supposedly static object is suitable as a landmark. When the object has been verified as a landmark, the data processing station creates a data record describing the object, which data record is transmitted to the vehicle.

主权项

1. A method for ascertaining and providing a landmark for position finding for a vehicle, comprising:
provision of a vehicle having an image recording device for recording an image of surroundings of the vehicle and an image evaluation device for evaluating the image and having a position finding device for ascertaining a position of the vehicle; provision of a data processing station having an image analysis device for analyzing the image to stipulate a landmark in the image; recording of an image using the image recording device; ascertainment of a position of the vehicle at the location of the recorded image by means of the position finding device; evaluation of the image using the image evaluation device; transmission of the recorded image and the ascertained position of the vehicle from the vehicle to the data processing station when the image evaluation device evaluates at least one of the objects that the recorded image contains as a static object; analysis of the received image by the image analysis device in order to establish whether the at least one object is suitable as a landmark; ascertainment of a position of the at least one object in the received image by the image analysis device when the at least one object is suitable as a landmark; production of a data record describing the at least one object by the data processing station when the at least one object is suitable as a landmark; and transmission of the data record to the vehicle.
