Abstract: Provided are a method for constructing a three-dimensional map in a high-definition map, a device and a storage medium. The method includes: acquiring vehicle trajectory data, where the vehicle trajectory data is three-dimensional trajectory data; matching the vehicle trajectory data with a lane in a two-dimensional map and determining vehicle trajectory data matched with the lane; and assigning a height to the lane in the two-dimensional map according to the matched vehicle trajectory data to obtain a three-dimensional map.

Abstract: A method and an apparatus for generating a high-precision map includes sampling road data for generating the high-precision map, and obtaining a sampling trajectory, wherein the sampling trajectory comprises sampling location points and road data corresponding to the sampling location points, obtaining a navigation map comprising first road elements, and generating a target high-precision map by associating the first road elements with the high-precision map based on the sampling trajectory.
