Method and device for automatic recognition of traffic-signs

Abstract

Abstract The present invention relates to a method and a device for automatic recognition of traffic-signs. This device essentially comprises: a laser source (2) emitting a single laser beam (3); a polarisation switcher (4) for this beam; a means (8) for splitting and polarising the beam (3) so that it reaches, on the one hand, a reference image medium (10), and, on the other and, a modulator (12) (EASLM) with which is associated a video camera (1); recombination and conversion optics (14, L2); a modulator (15) (OASLM); and a camera (16) converting into a control signal (S) the specific information transmitted by the modulator (15) when it is struck by the laser beam (3). This device is applicable in particular to the automatic recognition of traffic-signs on roads. <IMAGE>
