Embodiment Construction

[0057] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. 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] Such as figure 1 As shown, an embodiment of the present invention provides a lane line detection method, comprising the following steps:

[0059] S1. Collect images including the left and right lane lines of the lane where the vehicle is located;

[0060] S2. Extracting the lane edge target point in the image above;

[0061] S3. Perform perspective transformation on the extracted lane edge target point;

[0062] S4. Detect the straight line formed by the above-mentioned lane edge target points through the Hough transform, so as to obtain the lane line.

Abstract

The present invention provides a lane line detection method, comprising the following steps: S1, collecting an image of the left and right lane lines of the lane where the vehicle is located; S2, extracting the lane edge target point in the above image; S3, performing the extraction on the extracted lane edge target point Perspective transformation; S4. Detect the straight line formed by the above-mentioned lane edge target points through Hough transformation, so as to obtain the lane line. According to the lane line detection method of the present invention, before the Hough transform is performed, the extracted lane edge target points are subjected to perspective transformation, so that the calculation amount of the Hough transform can be reduced, the system reaction time can be reduced, and the driving safety of the vehicle can be enhanced. In addition, the present invention also provides a lane line detection system, a lane departure warning method and system.

Description

technical field [0001] The invention relates to the technical field of vehicle safety driving assistance, in particular to a lane line detection method and system, and a lane departure warning method and system. Background technique [0002] With the development of society, automobiles have become a popular means of transportation. Due to fatigue driving or distraction, accidents caused by vehicles deviating from lane lines are also increasing, and such accidents usually occur at high speeds, so they are more harmful. [0003] Studies have shown that if the driver is given a warning 1 second before a potential traffic accident occurs, most of the similar traffic accidents can be avoided. Therefore, real-time detection of lane lines, identification of whether the vehicle deviates from the lane, and timely reminders to the driver when the driver does not perform a lane change operation but the vehicle tends to deviate from the lane can greatly improve driving safety.
