Abstract

The present invention discloses a vehicle-mounted lane line detection system and method. The system includes a processing unit arranged on a traveling vehicle and an image acquisition unit connected with the processing unit; the image acquisition unit is used for acquiring lane pictures in the traveling process of the vehicle in real time and sending the lane pictures to the processing unit; and the processing unit is used for obtaining lane line sample pictures in an offline or online manner to establish a lane line sample library, extracting the RGB pixel values of lane lines in the lane line sample library to establish a G-S color model, inputting the lane pictures in the traveling process on the basis of the G-S color model, detecting the lane lines in the lane pictures through likelihood probability calculation and threshold segmentation, and extracting the lane lines from the lane pictures through Hough transform. With the vehicle-mounted lane line detection system and method of the present invention adopted, influence caused by environmental change or illumination change can be eliminated, and a lane line detection effect can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of computer image processing, in particular to a vehicle lane line detection system and method. Background technique [0002] In recent years, driver assistance systems and unmanned vehicle technology have received widespread attention from researchers. Lane line detection is a crucial step in assisted driving and unmanned vehicle technology. The current mainstream lane line detection methods include lane line detection based on shape features, lane line detection based on color features, and lane line detection based on model features. The lane lines detected by the lane line detection method based on shape features need to have obvious lane line edges and are greatly affected by noise or other interference. Lane line detection methods based on color features are greatly affected by illumination. Lane line detection based on model features will detect a large number of edges irrelevant to lane lines and ...
