METHOD FOR LOCALISING A VEHICLE ON THE ROAD, AND SUITABLE VEHICLE

摘要

The localisation of a travelling vehicle (1) on the road (10) is carried out by a method according to which images of the road on which the vehicle is travelling are formed continuously or at pre-determined intervals by a camera carried by the vehicle and oriented towards the road, and the images are processed to determine the position of at least one reference line element (11) on the images, in such a way as to derive information which may represent the position of the vehicle on the road. A first camera (2) is oriented towards the front of the vehicle and a second camera (3) is oriented towards the rear of the vehicle, information from the images supplied by the two cameras being merged in order to obtain a result which represents the lateral position (d₁) and the orientation of the vehicle on the road, or an error information message.
