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 recoded 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. Wherein a normal SLAM or VIO algorithm only can access data of the past, in these steps, processing may also be done by looking at positions ahead, by using the recorded data.

A method for detecting and modelling of an object on a surface of a road by first scanning the road and generating a 3D model of the scanned road (which 3D model of the scanned road contains a description of a 3D surface of the road) and then creating a top-view image of the road. The object is detected on the surface of the road by evaluating the top-view image of the road. The detected object is projected on the surface of the road in the 3D model of the scanned road. The object projected on the surface of the road in the 3D model of the scanned road is modelled.

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.

System and method of matching of road data objects for generating and updating a precision road database

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. The server database performs the second step of object data processing comprising at least statistical evaluation and post processing to update the fourth data sets in the server database based on the third data sets.

A method of operating a navigation system determines a route between an origin and a destination and provides a photographic image showing a geographic area through which the route passes. The photographic image shows the geographic area from a land-based viewpoint. The method overlays a route highlight on the photographic image identifying a path to be traveled. The route highlight includes a symbol indicating at least one feature of the route selected from a group consisting of handicap accessible route, tree-lined route, well-lit route, quiet route, scenic route, crowded route, peaceful route, and bicycle friendly route.

Method of operating a navigation system using images

A method of providing geographic information for a navigation system comprises obtaining a request for a geographic region and accessing geographic data corresponding to the geographic region from a geographic database. The method also comprises providing a plurality of first map images generated from the geographic data. Each of the first map images represents a unique portion of the geographic region. When the first map images are displayed together, they provide a first map depicting the geographic region.

Method of providing geographic information for a navigation system

A method for operating a navigation system computes a pedestrian route for travel by a pedestrian. A request for the pedestrian route between a first location inside a building and a second location inside the building is obtained. A geographic database associated with the navigation system is accessed for data representing a plurality of pedestrian paths. A solution pedestrian route from the origin to the destination comprising a series of connected pedestrian paths between the first location and the second location is determined. A guidance message that identifies a feature visible from at least one of the pedestrian paths is provided.

A photograph repository system includes data storage for storing photographs in the form of digital data files and a search feature that provides for searching for photographs by location and optionally by other search criteria. In one embodiment, a photograph repository service is accessible to users over a common data network, such as the Internet. In the photograph repository service, each stored photograph is associated with a location, i.e., where the photograph was taken and/or the location of an object in the photograph. Users can search for and obtain copies of their own photographs that they had stored previously with the photograph repository service. In addition, users can search for and obtain copies of photographs that had been taken by other users and stored with the photograph repository service. The photograph repository system can also be implemented as a standalone system, a hybrid system, or a peer-to-peer system.

A method is disclosed for providing guidance to a destination with a computing system that uses geographic data indexed by affinity relationships. A user specifies a municipality of relatively greater importance that is located nearby the desired actual destination. The computing system provides guidance to the user to follow a route to the specified municipality. While the user is following the route to the specified municipality, additional routes are calculated to each of a plurality of roads that cross into an affinity domain associated with the specified municipality. Before the user reaches the point at which any of the additional routes diverge from the route to the specified municipality, input is obtained from the user, one or more times as needed, specifying either another municipality progressively closer to the desired actual destination or the actual desired destination. Guidance is provided to the user to follow the routes to the closer municipalities or the desired actual destination.

Method of using map data that has been organized for affinity relationships

A method for operating a navigation system computes a pedestrian route for travel by a pedestrian. A request to calculate the pedestrian route from an origin to a destination and a walking preference for the pedestrian route identifying a feature of the pedestrian route are obtained. A geographic database associated with the navigation system is accessed for data representing at least one pedestrian path. The data representing the pedestrian path includes lighting level attribute information for the pedestrian path. A valid solution pedestrian route from the origin to the destination comprising a series of connected pedestrian paths that support the walking preference is determined.

A method of operating a navigation system determines a route between an origin and a destination and provides a photographic image showing a geographic area through which the route passes. The photographic image is obtained from a geographic database, and the photographic image shows the geographic area from a land-based viewpoint. The method overlays a route highlight on the photographic image identifying a path to be traveled. The route highlight extends along the path for a distance visible in the photographic image.

A method for collecting geographic data identifies a pedestrian segment associated with a path. Location information for the pedestrian segment is collected. Additionally, lighting level attribute information is collected for the pedestrian segment. The location information and the lighting level attribute information are stored in the geographic database that is stored on a computer readable storage medium.

A navigation system determines a route between a first location on a road network and a second location in a facility off of the road network. The system composes individual guidance messages for travel along a portion of the route on the road network. A pre-composed set of guidance instructions for travel in the facility along a portion of the route off of the road network are obtained from a geographic database associated with the navigation system.
