<p>Provided is a lane line detection method, comprising the following steps: collecting a lane line image including a left lane line and a right lane line of a lane where a vehicle is located; extracting lane edge target points from the lane line image; conducting perspective transformation on the lane edge target points; and by means of the Hough transformation, detecting a straight line formed by the lane edge target points as a lane line. According to the lane line detection method of the present invention, before the Hough transformation is conducted, the perspective transformation is conducted on the extracted lane edge target points, so that the Hough transformation calculation amount can be reduced, the system reaction time can be reduced, and the travel security of vehicles can be enhanced. In addition, also provided are a lane line detection system, and a method and system for lane deviation prewarning.</p> |
