摘要
针对高精度地图在车端的协同应用研究相对较少问题,本文首先详细阐述高精度地图在自动驾驶功能实现的应用架构;其次,结合自动驾驶应用实现对车辆周围道路环境的关注,从分发的路网模型、属性模型及自车位置模型表达对数据分发模型进行分析梳理;并以自动驾驶中导航规划为例,探讨高精度地图数据在应用实现时解析、传输、重构过程、数据分发逻辑结构和基本内容;最后总结展望,高精度地图服务将在车路协同应用支撑中起关键作用。
Regarding to the relative lack of research on collaboration between map data and vehicle’s autonomous function layer,this paper firstly discussed High-Definition Map application architecture.Then consideration of the highly attention to the road environment around the vehicle of autonomous driving realization,the data distribution model was analyzed from the road network model,the attribute model,and the vehicle position model expression.Meanwhile,it summarized the logical structure and basic distribution content through the discussion of data analysis,transmission,and reconstruction process in the navigation and planning function realization.At last,this paper looked forward to the future development and research of High-Definition Map in V2X.
