Abstract

The invention relates to an automotive automatic anti-glare device and a method thereof, mainly solving the problem that safety hazards occur easily under the influence of glare during night driving. The device consists of a CCD camera, an image grabbing card, a micro processor, an LED controller, a light source of a headlight system. The method comprises: the camera captures video images ahead; the image grabbing card transmits the video images to a memory of the micro process at a high speed and the micro process judges whether a vehicle is coming ahead according to the processing of the video images; the LED controller controls the light source of the headlight system to execute corresponding lighting mode according to the results of the judgment of the processor. The invention can judges automatically whether a vehicle is coming ahead according to the images captured by the vehicle-mounted camera, and automatically control the headlight system of the vehicle so as to generate glare for the coming vehicles, thereby contributing to safe driving at night and reducing the burdens of drivers.

Description

technical field [0001] The invention relates to an active anti-glare device and method for automobiles, in particular to actively adjust the lighting mode of the vehicle according to the characteristics of the night driving scene captured by a camera to achieve the purpose of anti-glare, and is used in the field of safe driving of automobiles at night. Background technique [0002] According to the statistics of the traffic department, the traffic at night or dawn only accounts for 25% of the whole day's traffic, but the accident rate during this period is as high as about 44%, and the serious traffic accident rate is twice that of the daytime. Excluding human factors such as driver drinking and fatigue driving, the main reason for the high number of traffic accidents at night is that drivers cannot see road signs, obstacles, oncoming vehicles and passers-by as clearly as they do during the day. One of the important reasons is glare. Glare is due to the relatively dark backg...
