System and method for generating digital road models from aerial or satellite imagery and vehicle-acquired data

摘要

A method for creating a digital road model for at least one road section includes: receiving and storing at least one trajectory of a vehicle for the at least one road section; receiving at least one image showing at least parts of the road section, the image having a perspective corresponding to an image recorded vertically downward from an elevated position; superimposing the at least one image on the at least one trajectory to correspond the trajectory to the course of a road in the at least one image; analyzing the at least one image in a corridor extending along and enclosing the trajectory to identify driving-relevant or positioning-relevant features of the road section in the corridor; and generating the digital road model from the identified features, aligned on the basis of the at least one trajectory and in the corridor enclosing the trajectory.
