The invention relates to a distributed lane-level guide line construction method and device, and the method comprises the steps: taking an intersection and a driving-in and driving-out road thereof as an independent unit, collecting all tracks passing through the intersection in the range of the intersection in each unit, traversing the driving-in road and the driving-out road where each track is located, and constructing a lane-level guide line; taking a lane-level driving-in lane and a driving-out lane as grouping labels, and carrying out statistics on a collection track in each group of driving-in and driving-out lanes; and finally, according to a set screening strategy, screening a track with a universal driving habit from the plurality of tracks to serve as a guide line communicated with the lane. And by parity of reasoning, constructing lane-level communication in each intersection unit so as to complete construction of a lane-level guide line of a high-precision map. According to the method, the intersection and the driving-in and driving-out road connected with the intersection are used as units for division, a single task is basically balanced, a large map can be quickly and automatically split into a plurality of mutually balanced tasks, and the lane-level guide line manufacturing efficiency is greatly improved.

    本发明涉及一种分布式的车道级引导线构建方法及装置,以路口和其驶入驶出道路作为一个独立的单元,在每个单元内,以路口范围收集穿过该路口的所有轨迹,遍历每条轨迹所在的驶入道路和驶出道路,以车道级的驶入车道和驶出车道作为分组标签,统计每组驶入驶出车道内的采集轨迹;最后根据设定的筛选策略,从众多轨迹中筛选出一条具备普适性的驾驶习惯的轨迹作为该车道连通的引导线;以此类推,构建每个路口单元内的车道级连通,以完成高精度地图的车道级引导线构建。以路口和与之相连的驶入驶出道路为单元进行划分,单个任务基本是均衡的,并且可以快速将一块很大的地图自动化拆分为很多个相互均衡的任务,车道级引导线制作效率大大提升。
