Improved Lane Line Detection Algorithm Based on Hough Transform

Abstract

In order to simplify the lane line detection algorithm based on Hough transform, we propose an algorithm directly identifying lane line in Hough space. The image is conducted with Hough transform, and the points conforming to the parallel characteristics, length and angle characteristics, and intercept characteristics of lane line are selected in Hough space. The points were directly converted into the lane line equation. Also, the lane lines are conducted with fusion and property identification. The experimental results showed that the lane can be better identified on expressways and structured roads. Compared with tradition algorithm, the identification is effectively improved.
