摘要:
A camera set up for fitting on board a motor vehicle. The camera has an electronic sensor, a multifocal, particularly bifocal optical device, an optical lens focused in long-range field, the multifocal optical device and the optical lens being set up to be able to form a first image (IM1) on the sensor, focused in long-range field, and a second image (IM2) focused in close-range field, these first and second images extending into respective distinct regions of the sensor.

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 (102) in a research area of said captured images, characterized in that said method of raindrop detection comprises a rejection step (103) in which edges that are uncharacteristic with respect to a raindrop are rejected. This invention also relates to an associated driving assistance device.

The invention relates to a method of fog and raindrop detection on a windscreen (200), comprising a raindrop detection application (201) and a fog detection application (202), characterized in that said fog detection application (202) comprises a step (202b) in which an indication of the presence of raindrop is detected, said indication of raindrop presence triggering a switch from said fog detection application (202) to said raindrop detection application (201).
摘要:
The invention relates to a method and a camera assembly for detecting raindrops (28) on a windscreen of a vehicle, in which at least one image (14) is captured by a camera (12), at least one reference object (20) is identified in a first image (18) captured by the camera (12) and the at least one identified object (20) is at least partially superimposed to at least one object extracted from a second image (16) captured by the camera. Raindrop (28) detection is performed within the second image (16).

The invention relates to a vehicle (10) with at least one camera (16), by means of which at least one image area of a surrounding of the vehicle (10) 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 (10), and with a tunnel detection device (44) designed for determining an average brightness of the at least one image area. The tunnel detection device (44) comprises a device (46) 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 (10).
摘要:
A detection method, system and device for a motor vehicle (V1). The method, system and device uses at least one camera which has a predetermined field of vision. The method includes the following steps: receiving information which is representative of a driving state associated with the vehicle; and modifying the field of vision of the camera, and in particular its orientation, according to the information.
摘要:
A method for detecting a phenomenon affecting visibility generated by an automotive vehicle, comprising the steps of emitting a first beam of light, which beam of light can be reflected by an obstacle; emitting a second reference beam of light using a second emitting source; receiving on a receiver the reflected beam of light resulting from the first beam of light being reflected by an obstacle, and the second beam of light sent directly to the input of the receiver; generating one or more detection signals as a function of a combination of the reflected beam of light in the event of an obstacle and a reference beam; and comparing the modulation of one or more detection signals generated using reference data. According to the invention, the first and second beams of light are infra-red beams, and they are directed towards the rear of the vehicle.

摘要:
A system and method for controlling a vehicle headlamp, the headlamp being equipped with an automatic switching unit between high beam and low beam lighting modes and with a bending light function (DBL). The method comprises a step of making the bending light function (DBL) change from a first active state to a second state for detecting a combination of conditions comprising an active state of the automatic switching unit between high beam and low beam lighting modes and an active state of the high beam lighting mode.
