Title:
LANE LINE SPLICING METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/098953
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present disclosure are a lane line splicing method and apparatus, and an electronic device and a storage medium. The method comprises: determining a first lane line curve and a second lane line curve, which are to be spliced and are in a first coordinate system; determining a splicing constraint point on the basis of the first lane line curve and the second lane line curve; on the basis of the splicing constraint point, adjusting a first curve parameter corresponding to the first lane line curve, so as to obtain an adjusted first target curve parameter corresponding to the first curve parameter; on the basis of the splicing constraint point, adjusting a second curve parameter corresponding to the second lane line curve, so as to obtain an adjusted second target curve parameter corresponding to the second curve parameter; and determining a spliced lane line on the basis of the first target curve parameter and the second target curve parameter. In the embodiments of the present disclosure, curve parameters of two lane line curves are adjusted on the basis of a splicing constraint point, such that the two adjusted lane lines can be smoothly and continuously spliced together, thereby facilitating an improvement in the fusion effect of the lane lines.
