用于增强型数字地图的特殊交叉路口道路建模(英文)
发布时间:2021-06-25 19:59
针对中心区域被植被或人工景观覆盖的特殊交叉路口场景,提出了一种基于cardinal样条的数字地图车道级道路建模方法.首先,采用cardinal样条曲线来拟合特殊交叉路口内部的虚拟车道,建立一个初始的道路模型,此模型由一系列的控制点和张力参数确定.然后,针对该初始模型,提出一种渐进优化算法确定最终的道路模型,该算法根据道路曲率的变化程度确定合理的控制点和最优的张力参数,以实现道路模型高效性与可靠性两者之间的平衡.最后,通过实验对所提方法进行了验证和评价.结果表明,在交叉路口中心区域被植被或人工景观覆盖的情况下,此方法能够有效地描述这类特殊交叉路口的车道级拓扑关系和几何细节,同时能够较好地实现道路模型高效性与可靠性之间的平衡.
