摘要: [目的] 高精地图是高阶智能驾驶(高阶智驾)的核心支撑,其规模化应用面临智驾行驶安全与地理信息安全的双重挑战。本文通过系统梳理高精地图的核心表达需求,提出了一套多维度优化的表达策略。[方法] 该策略具体包括地图表达范围拓展、特征地物高度分档及连续地面起伏分解3类关键技术,并在多类典型场景中开展仿真测试、实地验证与案例检验。[结果] 结果显示,在不突破地理信息安全底线的前提下,该策略可将高阶智驾的安全事故率降低至原来的1/10,满足其对特征地物误判率及地面起伏误差的安全要求。[结论] 基于此策略,广州已顺利完成5宗高精地图审图业务,审图时效提升75%,为全国范围内高精地图的合规应用与智能网联汽车产业规模化发展提供了重要支撑。

Abstract: [Purposes] High-precision map serves as a core support for advanced intelligent driving,yet its large-scale application faces dual challenges: ensuring driving safety and safeguarding geographic information security.This study systematically examines the core representational requirements of high-precision map and proposes a multi-dimensionally optimized representation strategy.[Methods] The approach incorporates three key technical innovations: expanded map coverage,hierarchical categorization of feature elevations,and decomposition of continuous terrain fluctuations.Simulations,field tests,and case validations are conducted across various typical scenarios.[Findings] The results show that,on the premise of not breaching the bottom line of geospatial information security,this strategy can reduce the safety accident rate of high-level intelligent driving to about 1/10 of the original rate,meeting its safety requirements for misjudgment rate of feature ground objects and ground undulation error.[Conclusions] Based on this strategy,Guangzhou has successfully completed the map review work for five high-precision map projects,with the review efficiency improved by 75%,providing important support for the compliant application of high-precision map nationwide and the large-scale development of the intelligent connected vehicle industry.
