Embodiment Construction

[0096] exist figure 1 In , a general scenario of an unmanned vehicle driving on a road is shown. The road network 100 includes a plurality of roads 101 . Each road has specific characteristics, such as width, direction, curvature, number of lanes in each direction, lane width, or surface texture. There can be more specific details, such as curbs, centerlines, or even a single dash of a center-dashed line, or other markings, such as crosswalks. There are geographic objects 140 related to driving near the road. A geographic object can be any stationary object such as, but not limited to, buildings, trees, rivers, lakes, or mountains. In addition, there are a number of road facility objects 150, which may include objects and equipment installed on streets and roads for various purposes, such as benches, barricades, guardrails, mailboxes, telephone booths, street lights, traffic lights, traffic signs, buses stations, tram stops, taxi ranks, public sculptures and fruit bins.

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 geographicobject 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-basedinformation. 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.

Description

technical field [0001] The present invention relates to a method and system for collecting road data and environmental data in the vicinity of the road. Driving-related object data collected by multiple vehicles is matched against a public database. The invention also relates to databases containing these data and methods for building such databases. Background technique [0002] An increasing number of sensors and processors are integrated into modern vehicles in order to optimize vehicle operation and to provide new features and functions. In US 6,353,785 B1 a method and system for in-vehicle computer architecture are disclosed. The computing architecture includes a data network consisting of a plurality of interconnected processors, a first set of sensors responsive to environmental conditions surrounding the vehicle, a second set of sensors responsive to the vehicle's hardware systems, and A map database of data on geographic features in geographic areas. Vehicle ope...
