Abstract
A lane line detection method applied to a vehicle-mounted device is provided. In the method, the vehicle-mounted device converts a foreground image into a bird's-eye view (BEV) image, sets a peak of a horizontal histogram of the BEV image as a starting point for moving the sliding window, and generate a main lane line by fitting multiple non-zero pixels of the horizontal sliding window. The vehicle-mounted device calculates a confidence coefficient of each horizontal sliding window; and sets a previous one before the preset number of continuous horizontal sliding windows as a previous horizontal sliding window and determines an end point of the main lane line according to the previous horizontal sliding window when the confidence coefficients of preset number of continuous horizontal sliding windows are less than a predetermined threshold. The method improves accuracy of identifying lane lines.
