Method and system for rapid traffic lane detection based on GrowCut

Abstract

The invention discloses a rapid traffic lane line detection method based on GrowCut, which comprises the following steps of: acquiring surveillance video and choosing at least one frame of image as a key frame; demarcating an edge segmentation seed point in the key frame image; performing edge segmentation according to the GrowCut algorithm; performing smoothing filtering on the segmentation result by a median filter; performing edge extraction on the result of the smoothing filtering; performing bisection treatment on the edge extraction result; and fitting the traffic lane line through a polynomial curve fitting method according to the result of the bisection treatment to get the final traffic lane line. The invention further provides a system for rapid traffic lane line detection based on GrowCut. A traffic lance line detection system implemented through the method provided by the invention is high in reliability, low in operating cost and capable of being widely used in the fields of intelligent traffic and public security.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for quickly detecting lane lines based on GrowCut. Background technique [0002] Lane line detection is the primary link and key step in automatic calibration of PTZ cameras, intelligent video analysis, car assisted driving, and automatic navigation of outdoor robots. Features, separate the lane line from the background, and then obtain the direction of the lane line or the area range of the marked lane. The existing lane line detection methods mostly use the classic Hough transform and morphological methods, and the detection results are affected by factors such as video image resolution and road conditions, and the error is usually large. In addition, there are other methods. The literature retrieval results of the existing lane line detection technology are as follows: [0003] Patent Publication No. CN 101608924A discloses a lane line detection...

Problems solved by technology

The device of this invention is too complicated and is only suitable for situations where there are dotted and solid line marks and lane boundary lines are obvious

However, in the road condition cameras currently deployed in my country, there are still a considerable number of cameras that are analog devices, and the resolution of video images is not high, so the effect of using the device described in this invention to detect lane lines is not good enough.
