Problems solved by technology

However, there are not only straight lanes but also curved lanes on real roads. When there are curved lanes on real roads, the lane lines detected by traditional methods are not accurate. Therefore, the lane departure warning system cannot achieve accurate warnings. , it can be seen that there is an urgent need for a method that can accurately detect curved lane lines

Abstract

The invention provides a curving lane line detection method and device and a terminal, which relate to the technical field of auxiliary driving. The method comprises the following steps that the edgebinary image of a road image to be detected is longitudinally segmented into a preset number of sub-images; in the edge binary image, a road vanishing point and a lane line of the sub-image are determined according to a candidate lane line detected in the sub-image; whether a bent part exists in the lane line or not is determined according to the discrete degree of the road vanishing point and theslope of the lane line; if the bent part exists, the edge binaryzation is carried out and a curve which is used for representing the bending part of the lane line is fitted in the image. By applyingthe method, the curved lane line can be accurately detected, so that a lane deviation early warning system can be assisted to realize correct early warning as far as possible.

Description

technical field [0001] The present application relates to the technical field of driving assistance, and in particular to a method, device and terminal for detecting curved lane lines. Background technique [0002] Lane Departure Warning System (LDWS for short) is an important part of the automotive advanced driver assistance field. In the workflow of the early warning system, lane line detection is a core link, and the accuracy of the lane line detection results will directly affect the working effect of the lane departure warning system. [0003] At present, in the lane departure warning system, the traditional method, such as the Hough transform line detection method, is used to fit a straight line in the road image, and the fitted straight line is used as the lane line. However, there are not only straight lanes but also curved lanes on real roads. When there are curved lanes on real roads, the lane lines detected by traditional methods are not accurate, so the lane dep...
