Abstract

The invention discloses a lane line confirmation method in a lane line detection system. The method comprises the following steps that: 1, a camera collects an image; 2, edge enhancement is carried out on the image collected by the camera; 3, binary processing is carried out on the image after the edge enhancement; 4, candidate edge points at the inner side of a lane line are screened out according to characteristic rules of the lane line; 5, a fitting technology is adopted for carrying out fitting on the inner edge of the lane line, and obtaining a line or curve model of a lane; and 6, confirming the lane line. The image collected by the camera in the step 1 is a gray level image or a color image, if the image is the color image, the color image is converted into the gray level image through a color image to gray level image conversion formula.

Description

technical field [0001] The invention belongs to the field of smart cars, and in particular relates to a lane line confirmation method in a lane line detection system. Background technique [0002] Cars have become more and more important means of transportation in people's lives. In order to better improve the safety of cars and the comfort of drivers during driving, car intelligence has become the mainstream of car development. Among them, the lane keeping system detects the lane line in front of the vehicle based on the image collected by the camera, and when the vehicle deviates, the system can automatically adjust the steering wheel to make the vehicle return to the center of the lane. The lane line detection technology in this system determines whether the lane line detection is effective, and directly determines the effectiveness of the later steering wheel control. Therefore, the accuracy of lane line detection is directly related to the correctness of the control of...
