Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0028] The lane line detection method provided by this application can be applied to such as figure 1 shown in the application environment. In this embodiment, it is taken that the terminal 102 is a car terminal as an example. First, the car terminal 102 collects the original image of the lane line, detects the lane line on the original image, obtains the fitted lane line, and displays the fitted lane line, or makes the controller in the car terminal 102 control the lane line according to the fitted lane line. The car remains stable and smooth. In other embodiments, the...

Abstract

The present application relates to a lane line detection method and apparatus. The method comprises the following steps of: converting an image to be processed into a color space including a saturation channel and a luminance channel to obtain a color space image; based on the saturation channel and brightness channel of color space image, obtaining the image segmentation information of color space image by filtering, wherein the image segmentation information includes: first edge information obtained by gradient direction filtering of saturation channel and second edge information obtained byhorizontally filtering a saturation channel and a luminance channel; determining a lane line binary map based on image segmentation information; according to the effective pixel points in the binarydiagram of lane line, carrying out the curve fitting to obtain the fitting lane line. The method can effectively avoid the interference of shadows, vehicles or other obstacles, and improve the accuracy of lane fitting.

Description

technical field [0001] The present application relates to the technical field of intelligent driving, in particular to a lane line detection method and device. Background technique [0002] In recent years, with the continuous development of computer and robot technology, intelligent driving technology has also developed rapidly. In intelligent driving technology, sensing the road environment through the on-board sensor system and accurately detecting the lane lines in the road are the key factors to realize intelligent driving. Therefore, how to ensure accurate detection of lane lines in various complex natural environments is a difficult problem to be overcome to effectively improve the performance and safety of intelligent driving. [0003] None of the current lane line detection methods can solve the interference of complex conditions such as shadow occlusion, vehicles or other obstacles on lane line detection, and these interferences greatly reduce the accuracy of lane...
