摘　　要：高精地图为自动驾驶提供了重要的先验知识和安全冗余保障,可作为其他传感器的有效补充,是实现自动驾驶的关键能力之一。高精地图需能精准反映出不断变化的道路场景,才能支持精准的车辆定位、感知、路径规划等自驾应用。由于传统的采集更新模式周期长、成本高,因此基于大量社会车辆进行地图数据采集的"众包更新"模式应运而生。自动驾驶车辆搭载的相机,可识别车道线、交通标牌等丰富的地图要素信息,是实现高精地图大规模快速更新的最佳解决方案。HD Map provides important prior knowledge and safety redundancy guarantee for autonomous driving,which can be used as an effective supplement to other sensors,and is one of the key capabilities to achieve Autonomous Driving.HD Map needs to accurately reflect changing road scenarios to support accurate vehicle positioning,perception,path planning and other applications.The traditional collection and update mode has a long cycle and high cost,so the"crowd-sourced update"mode based on a large number of social vehicles comes into being.Cameras carried by autonomous vehicles can identify rich map elements,such as lane markings and traffic signs,which is the best solution to realize large-scale and rapid update of HD Map.
