Abstract

The system by detection of lane marking comprises a detection part for identifying and acquiring information of roads where vehicles drive and an image processing part for processing the road information acquired by the detection part. The image processing part comprises a lane marking identifying module, a lane marking tracking module and a lane marking identifying record management module. The lane marking identifying module identifies and detects the road information acquired by the detection part; the lane marking tracking module tracks stored lane marking information detected and accumulated by the lane marking identifying module and acquires inferred lane marking tracking information; the lane marking identifying record management module determines the validity of the lane marking information by means of the interpolated results of the lane marking information acquired by the lane marking identifying module and the lane marking tracking information acquired by the lane marking tracking module. According to the invention, the lane marking tracking information is inferred by means of tracked and accumulated lane marking information, and the interpolated result of the detected lane marking information is obtained, and therefore the stability and the reliability of the detected lane marking information are improved.

Description

technical field [0001] The invention relates to a lane line recognition system. In particular, it relates to a method of tracking lane lines based on the lane line history information obtained from the lane line recognition results, and improving the reliability of the recognized lane line information based on the tracking results when judging the validity of the lane line information. Lane recognition system. Background technique [0002] Lane Keeping Assist System (LKAS for short) is a necessary system to ensure driver safety. Generally, such a system detects lane markings, senses the driving state of the vehicle, and executes lane keeping control so that the vehicle does not deviate from the detected lane markings, or warns against lane deviation. [0003] The image of the road ahead is acquired by the camera sensor installed between the vehicle's windshield and rearview mirror, and the image processing of the acquired road image is performed in the camera system of the...
