Abstract

The invention discloses a high-precision map lane topology construction method and system, a server and a storage medium. An intersection lane topological connection rule is set; and intersection laneidentification information is matched with the intersection lane topological connection rule, so that an intersection lane topological connection route can be obtained; and therefore, the problem that an existing navigation map cannot provide a solution for an intersection lane topological connection route under the conditions of the lack and inconsistency of road signs and the absence of the directional meaning of the road signs.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a method and system for constructing a high-precision map lane topology, a server and a storage medium. Background technique [0002] Road network topology is an important part of path planning, providing decision support for vehicles to choose the correct and reasonable path. Traditional maps solve the problem of where vehicles should turn, but require human involvement. Therefore, it is necessary to provide a lane-level topology description, combined with a positioning system to provide auxiliary decision-making for automatic driving. [0003] At present, the steering information cannot be automatically interpreted through the sensor, and the steering decision needs to be completed with the help of map data. Therefore, providing an accurate topological connection information of the lane is a necessary prerequisite for automatic driving. The only guide arrows that ex...
