Embodiment Construction

[0057] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0058] The invention provides a lane line detection method.

[0059] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the lane line detection method of the present invention.

[0060] This embodiment proposes a lane line detection method, and the lane line detection method includes:

[0061] Step S10, collecting the image of the lane ahead during the driving of the vehicle;

[0062]The image of the lane in front of the collected vehicle during driving can be collected by the preset camera of the vehicle. In this embodiment, when the vehicle is started, the preset short-distance monocular camera is preferably used to collect the lane image. It is worth noting that the lane image collected in the present invention preferably collects an image of a small area preset in front of the ...

Abstract

The invention discloses a lane line detection method. The method comprises the steps that a lane image in front of a driving vehicle is acquired; the acquired lane image is preprocessed to acquire lane line pixels in the lane image; a coordinate value corresponding to each line pixel in the lane image is acquired; each acquired coordinate value is put into a preset straight line lane line model to generate a lane line of the lane image. The invention further discloses a lane line detection device. According to the invention, the accuracy of lane line detection is improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent vehicle assisted driving, in particular to a lane line detection method and device. Background technique [0002] With the development of science and technology, various technologies in the automotive field are becoming more and more mature, and cars have gradually entered various families. With the continuous improvement of road grades, especially the rapid development of expressways, the number of cars driving on the road is also increasing day by day. Moreover, the driving speed of cars is getting faster and faster, and the traffic flow is increasing, which leads to more and more car collisions and traffic accidents. [0003] At present, when people drive a car on the highway, they basically drive the car according to the lane lines that have been set up. Curved, and most of the existing lane line detection methods are to detect lane lines by establishing some curved lane line mode...
