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.

A method and system according to the invention comprises the means for or steps of: acquiring, by means of a digital image taking apparatus, a digital image with aberration of a scene, the digital image incorporating at least a first image zone and a second image zone, the first and second image zones having respectively at least a first resolution and at least a second resolution, the first and second resolutions being different; calculating a deployed digital image, by deployment of at least one zone of the digital image with aberration; applying an object detection algorithm in the deployed digital image; and supplying information on each object detected in the deployed digital image.
摘要:
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.
摘要:
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:
A system and method to support the driving of a motor vehicle comprising in particular a system capable of capturing images, wherein the system for capturing images comprises a stereoscopic image capturing system having at least a first camera and a second camera, with the first camera presenting a field of vision) greater than the field of vision of the second camera, and with the stereoscopic system thereby conferring a degree of multifunctionality to the device supporting the driving of the vehicle.
摘要:
A process for the detection from a vehicle of a visibility interference phenomenon, comprising the following steps: the emission of a beam of light to illuminate the rear of the vehicle, the beam of light being emitted into a field of vision of a camera mounted in the vehicle, and the determination of a presence and the nature of a visibility interference phenomenon on the basis of at least one image captured by the camera.
