Abstract

The invention discloses a road structure extraction system and method based on vector lines. The method is configured to acquire the vector line data of a high-precision map; extract at least one pre-selected road structure and / or at least one suspected road structure in the vector line data according to at least one pre-acquired standard road structure model, and mark the suspected road structure; judge whether at least one marked suspected road structure is a candidate road structure or not; after judging that the marked suspected road structure is a candidate road structure, extract the candidate road structure; and correct and / or supplement the pre-selected road structure and / or the candidate road structure. The standardized pre-selected road structure can be automatically extracted according to the standardized standard road structure model and the non-standardized suspected road structure is marked and then the suspected road structure is further processed through the screening mode. Compared with the road structure extraction means which purely depends on operator screening in the prior art, the extraction efficiency and precision are improved.

Description

technical field [0001] The invention relates to the technical field of measurement and control, in particular to a vector line-based road structure extraction system and method. Background technique [0002] With the complication of transportation network and the diversification of vehicle types, the requirement for the refinement of high-precision electronic maps is getting higher and higher. [0003] When high-precision maps are applied in the field of autonomous driving, it is necessary to provide location and topology information based on roads and lanes. Then, when making high-precision maps, it is necessary to extract structural information such as intersections and lane changes, such as intersections at ordinary traffic lights. [0004] In the prior art, high-precision methods for extracting road structure information such as intersections, lane changes, etc. are generally based on raw data such as laser point clouds, or based on shape lines extracted from raw data. ...
