基于中心导航车载地图旋转的研究

Study of Vehicle Map Rotate Based on Center Navigation

为了满足车载中心导航系统中地图数据显示实时性的需求,提出地图分块存储,及地图局部刷新机制;同时,针对地图数据的显示方式,本文主要研究了实现地图旋转的三种方法,并选择其中最优的方法进行了仿真实验。实验结果表明,本文所设计的地图旋转方法能够满足地图显示的实时性。

In order to satisfy the requirement on the real-time displaying of the map data in Vehicular Center Navigation system,this paper proposes the map storage in blocks and the machanism of the map part refreshing;meanwhile,aimed at the means for the map data displaying,this paper studies three methods of accomplishing the map revolving,and chooses the most excellent one to conduct the simulation.The experimental results show that the method that this paper designs can satisfy the real-time displaying of map.
