Title:
VEHICLE GUIDANCE METHOD AND SYSTEM BASED ON VISUAL SEMANTIC VECTOR, AND DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/088445
Kind Code:
A1
Abstract:
Provided in the present application are a vehicle guidance method and system based on a visual semantic vector, and a device and a medium. The method comprises: acquiring a road image, and classifying pixel points in the road image, so as to obtain pixel point categories; performing point set division according to pixel point positions and categories, so as to obtain a plurality of pixel sets, wherein each pixel set consists of pixel points, which have consecutive positions and are of the same category; projecting the pixel points in each pixel point set to a ground coordinate system, so as to obtain three-dimensional coordinate values of the pixel points in each pixel point set; according to the three-dimensional coordinate values of the pixel points, determining the semantic coordinates and direction of the corresponding pixel point set to be a semantic vector of the pixel point set; and performing pavement marker positioning according to the semantic vectors, so as to guide a vehicle to travel. The present application can enhance the robustness of semantic vectors, thereby providing reliable data support for subsequent vehicle positioning.
