A method and apparatus defines boundaries of the roadway and the lanes therein from images provided by real-time video. The images of the roadway are analyzed by measuring motion between images and detecting edges within motion images to locate edges moving parallel to the motion of the objects, such as vehicles, thereby defining the approximate boundaries of a lane or roadway. A curve is then generated based on the approximate boundaries to define the boundaries of the lane or roadway.
L'invention se rapporte à un procédé et à un appareil délimitant une chaussée et ses voies de circulation à partir d'images obtenues par vidéo en temps réel. On analyse les images de la chaussée en mesurant le déplacement entre les images et en détectant les bords à l'intérieur des images mobiles afin de localiser les bords se déplaçant parallèlement au déplacement des objets, tels que des véhicules, et formant les limites approximatives d'une voie de circulation ou route. Une courbe est ensuite générée sur la base des limites approximatives afin de délimiter la voie de circulation ou chaussée.
