The invention provides a lane line detection method. The lane line detection method comprises the following steps: S1, acquiring an image comprising a left lane line and a right lane line of a lane where a vehicle is disposed; S2, extracting lane edge object points in the image; S3, performing perspective transformation on the extracted lane edge object points; and S4, detecting a line composed of the lane edge object points through Hough transformation to obtain a lane line. According to the lane line detection method provided by the invention, before the Hough transformation, the perspective transformation is firstly carried out on the extracted lane edge object points, such that the computational complexity of the Hough transformation can be reduced, the system reaction time is reduced, and the vehicle driving safety is enhanced. Besides, the invention also provides a lane line detection system, and a lane deviation early warning method and system.
