A device for luminously signalling a change of lane for a motor vehicle comprises at least one element for detecting the change of lane of the vehicle and at least one control module configured to receive and process information coming from the one or more elements for detecting the change of lane and to accordingly control at least one emitting and projecting element configured to project at least one pictogram onto the road.

Device for luminously signalling a change of lane for a motor vehicle

The invention relates to a camera arrangement for a vehicle, comprising a camera (), wherein by means of the camera arrangement a brightness of the surroundings of the camera is determinable. The camera arrangement comprises a storage device () in which is stored at least one brightness reference value () capturable by the camera. This reference value () is correlated with a corresponding value () indicative of a photometric quantity measurable by means of a photometer () at this brightness. An evaluation unit of the camera arrangement is designed for comparing a brightness value determined by the camera with the brightness reference value (). Furthermore, the invention relates to a method for calibrating a camera () and for operating a camera arrangement.

The invention relates to a vehicle () with at least one camera (), by means of which at least one image area of a surrounding of the vehicle () is capturable, the image area comprising a plurality of pixels and being arranged obliquely above a vehicle front as viewed in the direction of travel of the vehicle (), and with a tunnel detection device () designed for determining an average brightness of the at least one image area. The tunnel detection device () comprises a device () for feature or edge detection, by means of which differences in the brightness of pixels differing from each other are capturable and thus features characterized by abrupt changes in brightness are detectable in the at least one image area. Moreover, the invention relates to a method for operating a camera arrangement for a vehicle ().

The invention relates to a method of raindrop detection on a vehicle windscreen by capturing images using a camera which is at least focused on the windscreen, including a step of detecting edges () in a research area of said captured images, characterized in that said method of raindrop detection comprises a rejection step () in which edges that are uncharacteristic with respect to a raindrop are rejected. This invention also relates to an associated driving assistance device.

A system and method for determining a region of interest in an image, characterized in that it comprises the following steps: a plurality of lines Lformed by pixels is defined in the image; in each line L, a plurality of segments Sconstituted by pixels is defined; a luminance level NVG(S) is calculated for each segment Sbased on the luminance of the pixels constituting this segment S; depending on this luminance level NVG(S) the segment Sis selected or excluded from the region of interest; and the region of interest is obtained by amalgamating all the segments selected for each line.

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.
