Abstract

Embodiments of the present invention provide a road structure information extraction method, unmanned aerial vehicle, and automatic driving system. The method includes: obtaining at least one frame ofimage data of the road (S201); determining a semantic map of the road based on the at least one frame of image data (S202), and determining road structure information of the road according to the semantic map and the road structure model, wherein the road structure information includes lane grouping information (S203), which realizes the automatic extraction of road structure information withoutmanual annotation, and can extract road structure information in real time, which improves the extraction efficiency of road structure information and the road structure information includes not onlylane information but also lane grouping information, and description of the road structure is more specific. .

Description

technical field [0001] The embodiments of the present invention relate to the technical field of unmanned driving, and in particular to a method for extracting road structure information, a drone and an automatic driving system. Background technique [0002] In unmanned driving scenarios, road structure information is an indispensable and dependent information for safe driving. With the rapid development of unmanned driving technology, the requirements for map accuracy and information volume are gradually increasing. Traditional maps can no longer meet the needs. A high-precision map that can provide high-precision and detailed road structure information is needed. High-precision maps not only require high-precision data, but also contain detailed and well-organized road structure information. [0003] In the prior art, the road structure information contained in the road data is usually marked by manual labeling after the scene road data is obtained by using sensors, such ...
