Problems solved by technology

However, the lane line information contained in the ordinary road image is not comprehensive, and in the actual traffic road, the lane line is not always a straight line, and the lane line is extracted directly according to the straight line formed by the edge points of the lane line, which will cause the extracted lane line to be inaccurate , resulting in low lane line extraction accuracy. In addition, the edge detection of the ordinary road image requires a large amount of redundant image information to be processed, resulting in a slow edge detection speed, resulting in low lane line extraction efficiency.

Abstract

The invention discloses a lane line extraction method, apparatus and system, relates to the technical field of traffic, and mainly aims to improve lane line extraction precision and efficiency. The method comprises the steps of collecting a measureable real scene road image; by analyzing the measureable real scene road image, constructing a grid dynamic window-based lane identification region of interest, and performing lane line edge detection on the lane identification region of interest; and extracting lane lines according to lane line information obtained by detection and a lane line extraction model subjected to line fitting correction in a preset lane. The lane line extraction method, apparatus and system is suitable for measureable real scene road image-based lane line extraction.

Description

technical field [0001] The invention relates to the field of traffic technology, in particular to a method and device for extracting lane lines. Background technique [0002] With the rapid development of social economy, traveling by car has become the main way for people to travel. Motor vehicle travel has brought great convenience to people, but it also has great hidden dangers. According to incomplete statistics, the number of motor vehicle drivers has exceeded half, and hundreds of thousands of people die in traffic accidents every year. In order to reduce the occurrence of unfortunate accidents and improve the convenience and comfort of people's travel, it has become an inevitable trend to realize the automation of motor vehicles. Therefore, the detection of road lines, such as the detection of lane lines, is particularly important. The detection of lane lines can make automatic driving more intelligent and bring safer guarantees. [0003] At present, when extracting...
