摘要： A night vision method and system for producing a colour infrared image of a road scene situated in front of a vehicle. At least one projection device emits an infrared light towards the road scene. A colour sensor captures a colour image of the road scene and a monochrome infrared sensor captures a monochrome infrared image of the road scene. The colour and monochrome infrared images are combined to obtain the colour infrared image of the road scene.

摘要： A signal representing an image generated by at least one photosensitive device is processed in real-time to supply, from a scene to be observed having a high dynamic range between the signals corresponding to the darkest areas and to the brightest areas, an image containing no blooming areas. Images of different sensitivities are formed from the same scene to be observed. The brightness level of each point on the most sensitive image is determined. This level is compared with a predetermined threshold. The signal of the most sensitive image is delivered to the display device, for each elementary point on the most sensitive image having a brightness level below the predetermined threshold. An image signal calculated according to the brightness levels of the same elementary point in the images of different sensitivities is delivered to the display device, for any other elementary point on the most sensitive image.According to the present invention, images of different sensitivities are formed from the same scene to be observed, the brightness level of each elementary point on the most sensitive image is determined, this level is compared with a predetermined threshold, the signal of the most sensitive image is delivered to the display device, for each elementary point on the most sensitive image having a brightness level below the predetermined threshold, and an image signal calculated according to the brightness levels of the same elementary point in the images of different sensitivities are delivered to the display device, for any other elementary point on the most sensitive image.

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： In the invention, a light device is proposed equipped with a DC motor for causing the tilting of a pivoting plate, in addition, in the invention, a solution is proposed for preventing the DC motor from degrading too quickly. To this end, it is therefore proposed to limit, for example by means of an electronic control card, the supply current to the motor to a limitation threshold, at least during the phases in which the DC motor is functioning in locked torque.
