Abstract

La présente invention concerne un système de projection de panneau de signalisation, qui assure une excellente lisibilité des marquages routiers et ne se détériore pas dans le temps et dans lequel il est possible de modifier les détails du marquage. Le système (1) de projection de panneau de signalisation est équipé des éléments suivants : une unité (5) de projection de panneau, qui projette un motif de panneau, par émission d'un laser ; une unité (7) de projection de fond, qui projette un motif de fond, superposé sur le motif de panneau, en dirigeant sur lui la lumière d'un projecteur (11) rouge et d'un projecteur (12) vert ; et une unité (10) de commande de système, pourvue d'une unité (16) de stockage de données, dans laquelle des données (14) de panneau appartenant aux motifs de panneau et des données (15) de fond appartenant aux motifs de fond sont stockées par rapport à une pluralité de panneaux de signalisation et une unité (19) de transmission de données, qui transmet les données (14) de panneau à l'unité (5) de projection de panneau et transmet les données (15) de fond à l'unité (7) de projection de fond.
