Abstract

The invention relates to the technical field of high-precision maps, and provides a method, a device, computer equipment and a storage medium for automatically associating a road object with a road. According to the invention, the association efficiency of the road object and the road can be improved, and high-quality association information between the road and the road object can be provided for an automatic driving scene. The method specifically comprises the steps of determining a linear object representing a to-be-associated road object in map data, determining a lane marked line, meeting a preset distance condition on a road plane, of the linear object in the map data as a target lane marked line, and then obtaining a lane representative line corresponding to a road where the target lane marked line is located, and determining a projection relationship between the linear object and the lane representative line on a road plane, so as to construct a corresponding association relationship between the to-be-associated road object and the road represented by the lane representative line according to the projection relationship.

Description

technical field [0001] The present application relates to the technical field of high-precision maps, and in particular to a method, device, computer equipment and storage medium for automatically associating road objects with roads. Background technique [0002] High-precision maps refer to map data with centimeter-level high-precision. Map data can include layer information such as detailed road models, navigation data, and environmental perception data. an important basic technology. [0003] In various application scenarios of high-precision map data, road object information plays an important role in high-precision positioning, decision-making planning, control and other modules. Among them, road objects mainly refer to facilities that are fixed around the road, serve as an auxiliary reference guide for traffic driving, and ensure driving safety, such as traffic signs, traffic lights, guardrails, and curbs. [0004] In order to facilitate the rapid acquisition of road...
