路口车道完备性检查方法和装置、电子设备及存储介质
By obtaining the passable road pairs at intersections from standard electronic maps and the lane directions from high-precision maps, the system determines whether the intersection lanes are complete and supplements the data when incomplete. This solves the problem of incomplete intersection lanes in high-precision maps, enabling advanced driver assistance and autonomous driving functions, improving user experience and reducing safety risks.

AI Technical Summary
Technical Problem
In high-precision maps, incomplete mapping of intersection lanes prevents the implementation of advanced driver assistance and autonomous driving functions, posing safety risks.
Method used
By obtaining the passable road pairs associated with the intersection from the standard electronic map, obtaining the travel direction of the lanes from the high-precision map, determining whether the entry road can connect to the exit road in the high-precision map, determining whether the intersection lanes are complete, and supplementing the data when incomplete.
Benefits of technology
Ensure the integrity of lane data at intersections in high-precision maps to improve user experience and reduce safety risks.

Abstract
本公开涉及高精地图的路口车道完备性检查方法和装置、电子设备及存储介质，在本公开方案中，通过标准电子地图获取与待检查的路口关联的可通行道路对，再从高精地图中获取每个可通行道路对中与进入道路和退出道路关联的车道以及各条车道的通行方向，根据每个可通行道路对关联的各条车道的通行方向，确定高精地图中进入道路与退出道路的连通性，并在在进入道路与退出道路不可以连通时，确定路口车道不完备。如此，有效的检查出高精地图中不完备的路口车道，帮助高精产线对不完备的路口车道进行数据补充，以保证高精地图道路数据的完整性，进而提升了用户体验和降低了安全风险。
