Embodiment Construction

[0062] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0063] The flow chart of the present invention is as figure 1 shown. The implementation of the detection part of the present invention can be divided into three parts. The first part is to determine whether there are zebra crossings and road surface identifiers. In the second part, if there is a zebra crossing, it is combined with the zebra crossing to determine whether there is a stop line. In the third part, if there is a road surface identifier, it is combined with the road surface identifier to judge whether there is a stop line.

[0064] The first part is to judge whether there are zebra crossings and road surface identifiers. First, in the acquired grayscale image, select the region of interest, that is, the position where the stop line may appear. In order to determine whether there is a stop line combined with the zebra crossing, ...

Abstract

The invention relates to a stop line detection method based on rapid marker connectivity, which collects road surface grayscale images and extracts regions of interest; performs preprocessing on the extracted regions of interest to obtain a binary image; judges whether there is a zebra crossing in the image, and if there is , then detect the stop line according to the relationship between the zebra crossing and the stop line, and complete the stop line detection; otherwise, detect whether there is a road identifier in the image; if there is a road identifier, then detect the stop according to the relationship between the road identifier and the stop line line, to complete the stop line detection. The present invention calculates the connected domain information and utilizes auxiliary information such as zebra crossings and road surface identifiers to jointly complete the judgment of whether there is a stop line, and records the position of the stop line in the image.

Description

technical field [0001] The invention relates to the field of intelligent driving, in particular to a stop line detection method based on fast marker connectivity. Background technique [0002] With the development of society and science and technology, cars play an increasingly important role in people's daily life. While automobiles bring convenience to people's lives, they also bring huge hidden dangers to people's safety, especially at road traffic intersections, this hidden danger is particularly serious. The development of autonomous driving technology and unmanned driving has brought good news to solve this hidden danger. [0003] At present, in automatic driving and unmanned driving, the stop line detection technology based on Hough transform is often used. This technology uses preprocessing technology, image edge technology, and Hough transform technology to detect the "straight line" in the collected grayscale image, and judges whether there is a stop by prior kno...
