Abstract

The invention discloses a method and system for detecting road marker lines based on a geometric relation. The method and system extract each frame of image from a video, gray and binarize a color image, then perform morphological image processing, extract line features by using Hough transform, and combine discrete line segments by using the geometric relation to form road marking lines, correctsome abnormal line segments in view of a relation between frames, and finally draw the road marking lines in the frames and merge all the frames into a video. The method and system remove noise by morphological transformation, extract line features by using the Hough transform, combines the discrete line segments by the geometric relation to form the road marker lines, correct the abnormal line segments by using the inter-frame relation, are simple in algorithm, less in memory consumption and fast in processing speed. The method and system can be applied to road marker line detection in intelligent transportation.

Description

technical field

[0001] The invention relates to the technical field of computer vision, in particular to a method and system for detecting road marking lines based on geometric relationships. Background technique

[0002] With the rapid development of my country's economy, the number of car ownership is gradually increasing. While automobiles bring great convenience to our daily life, they also bring many problems, such as the gradual deterioration of urban traffic environment, increasingly serious traffic jams, and frequent occurrence of traffic accidents. Improving the intelligent level of traffic and reducing road traffic accidents will contribute to the safe, healthy and healthy development of the entire society, and it is also an important technical challenge faced by scientific and technological workers. Intelligent vehicles integrate environmental perception, decision-making, and various auxiliary functions, and are an important part of intelligent transportation sys...
