Title:
METHOD AND APPARATUS FOR DETERMINING HIGH-PRECISION NAVIGATION PATH, AND DEVICE, MEDIUM AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/040499
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present invention are a method and apparatus for determining a high-precision navigation path, and a device, a medium and a vehicle. The method comprises: acquiring a traditional navigation path provided by a traditional navigation map, and matching the traditional navigation path with a high-precision map; during a matching process, determining high-precision road sections in the high-precision map which correspond to all the trajectory points of the traditional navigation path, wherein the corresponding high-precision road sections comprise first high-precision road sections that are determined as matching the trajectory points, and second high-precision road sections that possibly match the trajectory points; and screening, from among the first high-precision road sections and the second high-precision road sections, a plurality of consecutive target high-precision road sections with a topological relationship, and according to the plurality of consecutive target high-precision road sections, generating a high-precision navigation path matching the traditional navigation path, wherein the starting road section and the ending road section of the high-precision navigation path are both first high-precision road sections. By using the technical solution, the accuracy of a matching result between a traditional navigation path and a high-precision map is improved.
