Abstract: Some embodiments include a method of generating an environment reference model for positioning comprising: receiving multiple data sets representing a scanned environment including information about a type of sensor used and data for determining an absolute position of objects or feature points represented by the data sets; extracting one or more objects or feature points from each data set; determining a position of each object or feature point in a reference coordinate system; generating a three-dimensional vector representation of the scanned environment aligned with the reference coordinate system including representation of the objects or feature points at corresponding locations, creating links between the objects or feature points in the three dimensional vector model with an identified type of sensor by which they can be detected in the environment; and storing the three-dimensional vector model representation and the links in a retrievable manner.

Abstract: A method of complementing a map of a scene with 3D reference points including four steps. In a first step, data is collected and recorded based on samples of at least one of an optical sensor, a GNSS, and an IMU. A second step includes initial pose generation by processing of the collected sensor data to provide a track of vehicle poses. A pose is based on a specific data set, on at least one data set re-coded before that dataset and on at least one data set recorded after that data set. A third step includes SLAM processing of the initial poses and collected optical sensor data to generate keyframes with feature points. In a fourth step 3D reference points are generated by fusion and optimization of the feature points by using future and past feature points together with a feature point at a point of processing. This second and fourth steps provides significantly better results than SLAM or VIO methods known from prior art, as the second and the fourth steps are based on recorded data.

Abstract: Method and system for generating an environment model for positioning include the generation of a 3D model of a scanned environment from a mobile entity, the 3D model being construed as a point cloud. A segmentation of the point cloud of the 3D model in a plurality of segmented portions of the point cloud is performed, and 3D objects are modelled directly from the point cloud by analyzing each of the segmented portions of the point cloud. The generated 3D model of the scanned environment is matched with an existing 3D model of the environment. A database representing of an improved 3D model of the environment is generated by aligning the existing 3D model of the environment and the generated 3D model of the scanned environment.

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.

Abstract: A communication system, network, interface, and port architecture are provided for transporting different types of data across a network. The network can be arranged by connecting the ports in a daisy-chain fashion to achieve a ring architecture or topology. The network forwards data according to a specific network protocol, and nodes among the network can use a recovered clock from the bitstream to drive the transmitter and create a synchronous network even thought the network can receive Ethernet packets which are typically targeted for an asynchronous network. Non-compliant data, such as Ethernet data, can be sent as packets within a frame structure. The frame is synchronized to Ethernet coding violations used to signal the beginning of each frame, and each packet can be immediately followed by a packet coding violation. The frame and packet coding violations are represented as a sequence of 4B/5B codes that are not valid codes and, therefore, not present as Ethernet encoded data.
