Front lamp following turning control method based on machine vision

Abstract

The invention aims at the problem that road lighting dead zones occur during night driving of vehicles and provides a front lamp following turning control method based on machine vision. The method includes: recognizing night lane lines to determine a pre-aiming distance of a current control cycle and a longitudinal distance corresponding to the current image frame; determining a road pre-aiming analyzing area in the current image frame, and performing transverse image correction to lane lines in the pre-aiming analyzing area; determining the included angle of the driving direction of a vehicle and the road, the road width and traverse distance from a vehicular camera to the left lane line and the right lane line; and identifying road conditions of the pre-aiming analyzing area and determining the front lamp turning angle. By the method, road lighting area in the pre-aiming distance is increased effectively, lighting dead zones in front of the vehicle is eliminated in real time, the front lamp turning angle is unaffected by vehicle driving, intelligent active control of front lamp following turning is achieved, and safety driving without visual dead zones of drivers is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automobile lighting, and in particular relates to a machine vision-based headlamp follow-up steering control method. Background technique [0002] Research statistics show that the probability of traffic accidents at night is much higher than that during the day. Among them, the blind area of ​​vision caused by insufficient lighting at night makes the driver unable to perceive and predict the danger of the road ahead, which is an important cause of night traffic accidents. [0003] Generally, the ordinary headlights installed on the car have only a certain lighting range regardless of the brightness. Therefore, when the lighting brightness of the road lighting facilities is low or even no lighting, due to the fixed headlights of the ordinary headlights, there will inevitably be blind spots without lighting on the road ahead. , especially when the vehicle is driving on curves and intersections, the driver...
