Abstract: In order to improve the accuracy of the lane line detection, an accurate lane line detection method was proposed, according to the feature that the texture features in the foreground region of lane image information were clearer. Aiming at the corresponding texture features in the lane left by rut, the characteristic diagrams of 5 scales and 8 directions were obtained by Gabor transform analysis with different scales at different directions. The characteristic diagrams were fused and texture direction characteristic together with index value of each pixel was obtained. The direction index value of each pixel was used to vote for the vanishing point, and then the vanishing point of the road was determined. Furthermore, a sector scanning area was determined by the vanishing point, and the lane marking was positioned. At last, the equation was established. The experimental results show that the method has strong robustness in strong light, shadow and lane line cloak.
