Abstract

The invention discloses a lane detection method based on Hough transform and terminal equipment. In the method, firstly a road image is filtered through a preset filtering template, and the transverse gradient of each pixel is calculated; then a pixel to be processed with a negative transverse gradient is searched, the transverse gradient of the pixel to be processed is set to be zero, and a gradient image is obtained according to the transverse gradient of each processed pixel; a binarization image corresponding to the gradient image is obtained and is subjected to Hough transform, and a corresponding Hough matrix is obtained; the local maxima search is carried out on the Hough matrix, a local maxima in the Hough matrix is obtained, and the position of a lane in the road image is determined according to the local maxima. Through the scheme disclosed by the invention, the position of the lane in the road image can be detected, compared with the prior art, the amount of computation can be greatly reduced, thus the time spent in lane detection is reduced, and the early warning effect is improved.

Description

technical field [0001] The present application relates to the field of image detection, in particular to a lane line detection method based on Hough transform and a terminal device. Background technique [0002] Automobile safety driving assistance system is an important content of the current international intelligent transportation system research. This system promotes the gradual realization of intelligentization of automobiles by providing increasingly perfect assisted driving functions for automobiles. Among them, the lane departure warning system (lane departure warning system, LDWS) is an important part of the car safety driving assistance system, which is used to assist the driver to reduce or even avoid lane departure accidents by means of an alarm. During the application process, LDWS collects the scene image of the scene where the car is located at all times based on monocular vision; then obtains the position of the lane line in the scene image through image proc...
