Patent number: 8063935Abstract: The present invention relates in particular to a method for the early detection of the arrival of a motor vehicle in a dark sector. In general terms, the invention proposes to use a camera for early detection of the arrival of the vehicle in a dark area, for example a tunnel. For this purpose, in the invention, provision is made in particular for using an image processing application for determining on a set of images supplied by the camera, whether the vehicle is ready to enter a dark area and, if it turns out that the vehicle will enter a dark area, to cause a switching on of the lights. Particular embodiments of the method according to the invention also make it possible to dispense with storing a plurality of templates corresponding to the various shapes of tunnel entrances, by providing judicious and reliable recognition criteria.Type: GrantFiled: March 30, 2006Date of Patent: November 22, 2011Assignee: Valeo VisionInventors: Joël Leleve, Abdelaziz Bensrhair, Julien Rebut
