Headlight adaptive control system and method based on machine vision

Abstract

The invention provides a headlight adaptive control system and method based on machine vision, and relates to the technical field of automobile intelligent front illumination. Data are monitored and collected simultaneously by multiple modules, a camera acquires road surface information, then images in a video are pre-processed so as to obtain better images, according to the characteristic of a vehicle at night, characteristic extraction of the images is carried out, feature vectors of a headlight, a taillight, a street light and other bright spots are extracted, the extracted feature vectorsare introduced into a support vector machine, training and verification of a training set and a test set are carried out through a deep learning convolutional neural network, angles of low and high beam lights are automatically adjusted through the automobile lights according to a real-time road surface condition to adapt to different road conditions, and meanwhile, the data is collected and integrated to enrich a database so as to provide reference for automatic adjustment and control of the low and high beam lights, and the dazzle influence caused by various conditions is effectively avoided, so that the traffic accident probability is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile intelligent front lighting, in particular to a machine vision-based adaptive control system and method for headlights. Background technique [0002] The vigorous development of the automobile industry and the continuous increase in the number of automobiles have brought about huge traffic problems, which have also caused a large number of traffic accidents, posing a huge threat to people's safety and property, and some of the traffic accidents are caused by light problems. As a result, driving safety issues have increasingly become the focus of attention, and various active safety devices have also emerged. The main function of automobile headlights is to illuminate the road surface, so that the driver can see the road conditions ahead, and prevent oncoming pedestrians or motor vehicle drivers from glare, dizziness and other discomforts. If the luminous intensity of the high beam of the headla...

Problems solved by technology

Although this can improve the driver's driving environment at night, it will also cause a lot of dazzling damage to the driver of the opposite car when meeting cars, and will also cause many traffic accidents.

When cars meet at night, if both cars have their high beams on, the drivers on both sides will not be able to see the road clearly due to the strong dazzling stimulation, which will cause great safety to people's lives and property. Hidden danger

Under normal circumstances, the driver does not deliberately use the lights in violation of regulations, but occasionally neglects the details of driving, which eventually leads to accidents.
