Lane line detection method and device, electronic device and storage medium

Abstract

The invention provides a lane line detection method and device, an electronic device and a storage medium. The method comprises the following steps of inputting an acquired image to be detected into a preset target detection model, and acquiring the first detection information and the second detection information of each grid in the image; performing non-maximum suppression processing on the first detection information of each grid, and obtaining the position of each lane line boundary point in the image; performing the non-maximum suppression processing on the second detection information of each grid, and obtaining the position of each lane center point and the corresponding lane width in the image; and determining the lane line in the image according to the position of each lane line boundary point, the position of each lane center point and the corresponding lane width in the image. Therefore, through the lane line detection method, the interference of noise on lane line detection is reduced, and the accuracy and the call rate of the lane line detection are improved.

Description

technical field [0001] The present application relates to the field of computer application technology, and in particular to a lane line detection method, device, electronic equipment and storage medium. Background technique [0002] There are two main methods for lane line detection. One is to extract features such as lane line color and brightness, and then perform edge detection, and use Hough transform to extract straight lines. This method is susceptible to interference from other colors and brightness, and is sensitive to noise, such as blurred lane lines, dark light, etc. Poor robustness and poor detection accuracy. [0003] Another method is to use the neural network for lane segmentation, and extract the center line of the segmented lane area as the lane detection result. This method is difficult to effectively segment under the conditions of overexposure, rainy weather, and lane line boundary wear, and it is easy to misdetect interference such as arrows and brake...
