摘要
为了增加驾驶辅助系统或者自动驾驶的可靠性,需要设计出高分辨率地图规格及模型。本文通过研究目前的车道设计方案,提出了两点优化方式以减少数据的冗余存储。在两车道之间建立特殊的关联关系,让不同的车道根据左右边线的不同有不同的断开方式;对虚拟路口车道线进行优化使用三次样条曲线来对路口车道进行抽象表达。
In order to increase the reliability of the driving assistance system or automatic driving,it is necessary to design high-resolution map specifications and models.This paper proposes a two-point optimization method to reduce the redundant storage of data by studying the current lane design.A special relationship is established between the two lanes,so that different lanes have different disconnection modes according to the left and right sidelines;the virtual intersection lane line is optimized to use the cubic spline curve to abstractly express the intersection lane.
