Abstract: A method and a system for generating and updating a digital road description database containing object-based information about at least one of a road object, a road furniture object and a geographic object is disclosed. A vehicle is collecting ambient data like images along multiple sections of its path, generating third data sets comprising at least location information and detailed object-based information. The third data sets are forwarded to a server database. The database identifies common groups of object reference points in multiple vehicle path sections and generates alignment functions for matching and/or aligning the at least one group of object reference points in at least two of the vehicle path sections relating to the same part of the road. The same alignment function is applied to all other third data sets of the same vehicle path section. The database updates the fourth data sets in the database based on processing the third data sets.

Abstract: A method and a system of a two-step object data processing by a vehicle and a database for generating and updating a digital road description database containing object-based information about road objects is disclosed. First, the server database comprises fourth data sets and generates and forwards first data sets to the vehicle, which are related to the area of interest of the vehicle. The vehicle is collecting a plurality of ambient data sets at least along a specific section of its path. It is performing the first step of object data processing by evaluating a selection of the plurality of ambient data sets and generating at least one second data set comprising at least location information and detailed object-based information. It further generates third data sets containing differences between the object-based information of the second data sets and the object-based information of the first data sets and forwards the third data sets to the server database.

Abstract: A method and a system for precision vehicle positioning based on a digital road description database containing fourth data sets with object-based information about at least one of a road object, a road furniture object and a geographic object is disclosed. First data sets based on the fourth data sets are forwarded to a vehicle. The vehicle is collecting ambient data like images along its path, generating second data sets comprising at least location information and detailed object-based information. During driving and after generating second data sets, the vehicle tries to identify in the second data sets the same driving-relevant objects and/or object reference points and/or groups of driving-relevant objects and/or object reference points as are contained in the first data sets.
