Therefore, according to the invention, as shown in FIG. 4, in addition to the auxiliary line 13, its shadow 16 is faded into the surrounding image 10. Thus, the auxiliary line 13 acts three-dimensionally, and the driver perceives the auxiliary line 13 as part of the real three-dimensional environment.

Abstract

La représentation intuitive de lignes auxiliaires (3) par un système d'assistance de conducteur basé sur caméra doit être améliorée. A cet effet, on crée un procédé pour représenter des lignes auxiliaires (3) qui aident un conducteur lors de la conduite d'un véhicule. Une image ambiante (1) du véhicule, y compris du sol (5), sur lequel le véhicule se déplace, est représentée sur un écran. L'image d'environnement (1) est superposée avec une ligne auxiliaire (3, 4). On représente également une ombre (6, 7) de la ligne auxiliaire (3, 4) sur le sol (5). De ce fait, la ligne auxiliaire donne un effet plus plastique et donne l'impression de faire partie de l'environnement.
