Abstract

The invention relates to a fast lane line detection method, comprising steps of performing unchanged-illuminance conversion on an inputted image, determining an unchanged-illuminance conversion parameter through an online calibration method based on a minimum entropy, using the determined unchanged-illuminance conversion parameter to divide a road in order to determine a boundary, performing double threshold value edge detection based on a determined boundary, performing estimation on a parameter space based on a result of a double-threshold value edge detection and detecting a line based on an estimated parameter space distribution condition. The fast lane line detection method can help to realize fast lane line detection in a robustness manner.

Description

technical field [0001] The disclosure belongs to the technical field of computer vision and graphics processing, and in particular relates to a fast lane line detection method. Background technique [0002] As the first link of automatic driving technology, lane line detection can effectively perceive the world around the vehicle and obtain the drivable area, which is the premise and guarantee for realizing lane departure warning and front vehicle anti-collision functions. For the lane line detection algorithm, there are Jiang R et al. in the literature "Jiang R, Reinhard K, Tobi V, et al. Lane detection and tracking using a new lane model and distance transform [J]. Machine Vision & Applications, 2011, 22 (4) :721-737." proposed to establish a triangle constraint on the lane, establish a lane line model, and grow the lane line through a particle filter in the distance-transformed image. This method can only deal with the situation when there are lane lines on both sides of...
