CA 2605837

A vehicle capable of preventing detection of stud-type lane marks from being impossible and a vehicle having a lane mark recognizer are provided. The vehicle includes installation interval recognizing means (21) which recognizes an interval (L) between Botts Dots, vehicle speed recognizing means (22) which recognizes a traveling speed (v) of the vehicle, image synthesizing means (13) which generates synthesized image data (M3) by combining image data (Ml) stored in an image memory (11) through an image input circuit (10) and image data (M2) stored in an image memory (12) through the same, imaging timing determining means (20) which determines the timing of imaging by a camera (2) on the basis of the interval (L) and the traveling speed (v) when acquiring the image data (Ml, M2) in such a way that the positions of the Botts Dots in the image data (Ml, M2) are different therebetween, and Botts Dots detecting means (14) which detects the Botts Dots from the synthesized image data (M3).

Véhicule palliant l~impossibilité de reconnaître un marquage de voie de type catadioptre et véhicule équipé d~une reconnaissance de marquage de voie. Le véhicule comprend un moyen de reconnaissance d~intervalle (21) pour reconnaître l~intervalle L entre des marquages en relief, un moyen de reconnaissance de la vitesse du véhicule (22) pour reconnaître la vitesse de circulation v d~un véhicule, un moyen de synthèse d~image (13) pour synthétiser des données d~image de synthèse (M3) en combinant des données image (M1) stockées dans une mémoire d~image (11) par un circuit d~entrée d~image (10) et des données image (M2) stockées dans une mémoire d~image (12), un moyen de détermination de synchronisation d~image (20) pour déterminer la synchronisation de la prise de vue par une caméra (2) sur la base de l~intervalle L et de la vitesse de véhicule v lors de l~acquisition des données image (M1, M2) de manière telle que les positions de marquage en relief dans les données image (M1, M2) soient différentes, et un moyen de détection de marquage en relief (14) pour détecter le marquage en relief à partir des données d~image de synthèse (M3).
