Method and device for vehicle positioning and lane-level path planning

Abstract

This application discloses a method and device for vehicle positioning and lane-level path planning. The vehicle positioning method includes: obtaining point cloud data around the vehicle and positioning information of a satellite positioning system within a positioning period, and obtaining the first feature according to the point cloud data. For the data of the identifier, match the map data corresponding to the first characteristic identifier in the pre-established electronic map according to the data of the first characteristic identifier and the positioning information of the satellite positioning system, and match the map data corresponding to the first characteristic identifier according to the matched map data to locate the vehicle. Through the above method, compared with the positioning of the existing satellite positioning system, the positioning of the first characteristic marker obtained by scanning the laser radar is more accurate, and, when there is no first characteristic marker within the positioning cycle, the controller can also Local area network vehicle attitude data and lane-level path planning routes can be used to locate the vehicle, which can also improve the accuracy of positioning.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a method and device for vehicle positioning and lane-level path planning. Background technique [0002] In real life, driving has become an important way of travel in people's daily life. [0003] At present, in order to make people travel more convenient, service providers will locate vehicles, and then provide users with required services based on the current vehicle positioning, such as automatic driving based on vehicle positioning. [0004] The existing vehicle positioning methods usually use the satellite positioning system installed on the vehicle to locate the vehicle. However, in some application fields with high actual demand for vehicle positioning, such as in the field of autonomous driving The accuracy of the installed satellite positioning system for positioning the vehicle cannot meet these application fields with high actual demand for vehicle po...
