Title:
IMAGE PROCESSING METHOD, LANE LINE DETECTION METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/131065
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application is an image processing method. The method can be applied to scenes including lane line detection, such as adaptive cruise, lane departure warning, and lane keeping assist. The method comprises: performing feature extraction on an image to be detected to obtain a first feature; processing bounding box information of said image to obtain a second feature, the bounding box information comprising the position, in said image, of a bounding box of at least one object in said image; and inputting the first feature and the second feature into a first neural network based on a transformer structure to obtain lane lines in said image. By applying the neural network based on a transformer structure to a lane line detection task, global information of the image to be detected can be obtained, and then the long-range connection between the lane lines is effectively modeled. Moreover, the perception capability for an image scene is improved by adding the bounding box information.
