Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050] An embodiment of the present invention provides a lane line detection method, which divides the area of ​​interest in the road image into at least two sub-areas, each sub-area processes the search for straight line segments in parallel, and detects lane lines in the searched straight line segments. It solves the problems of long time consumption, low real-time performance and small application range in the lane line detection process.

Abstract

The invention discloses a lane line detecting method and device. The lane line detecting method provided by the invention has the advantages that a region of interest in a road image is acquired, wherein the region of interest is an image region including a lane line; the region of interest is equally divided into at least two sub regions; a straight line segment included in each sub region in atleast two sub regions is detected in parallel; detected straight line segments in each sub region are combined; and a lane line threshold is used to filter combined straight lines to acquire the lanelines. According to the invention, consumed time in a lane line detecting process can be reduced, and the real-time performance of the algorithm is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation in image processing, in particular to a method and device for detecting lane lines. Background technique [0002] With the development of intelligent vehicles, when driving on the road, it is easy for the driver to deviate from the lane due to driver's inattention, fatigue or drunken driving and cause a car accident. In order to improve the safety of driving and the simplicity of operation, the use of corresponding auxiliary systems can prevent and reduce the occurrence of accidents. Lane line detection is mainly used in visual navigation systems. Through appropriate algorithms, the position of lane lines in the road image can be accurately and quickly found out from the captured road images to improve driving safety. Therefore, research on lane line detection technology become more and more important. [0003] At present, the feature-based lane detection algorithm is a common...
