摘要： 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.

摘要： A system and method for defining a window to search a region of interest for processing a road image, the search window having a longitudinal orientation directed according to the height of the image and being laterally delimited by two edges. The shape of the search window is adapted to the road configuration by defining at least one non-vertical portion on one of the edges. A preferred application is the processing of road images for determining visibility distances in foggy weather.

摘要： The invention concerns a system and method for detecting, at night, the presence of an element such as fog interfering with the visibility of a road scene situated in front of a vehicle, comprising the following operations: acquiring an image of the road scene, extracting, from the image of the road scene, at least one light halo produced by a lighting device of the vehicle, approximating a form of this light halo by an elliptic curve, comparing the form of this light halo with the elliptic curve obtained in order to deduce therefrom the presence or absence of an element interfering with visibility.
