导航地图信息实时增量法

Real Time Information Incremental Method of Navigation Map

鉴于电子地图数据现势性在导航中的重要性,本文提出一种导航地图实时增量法。该方法能够根据导航仪历经路径所观测到的交通建设变化状况,实时修正、增加或删除地图底层数据库的信息数据;同时,还具备自动记忆与标识驾驶者行驶路线的智能化与优化功能。观测信息的采集由导航仪外接图像传感器及其信号处理器予以实现。

As the importance of the electronic map data current in navigation, this paper presents a real-time navigation map information incremental method. The method can immediately correct, add or delete information in the underlying database of the map according to the changes of transportation construction conditions, that situation is experienced by the navigator in the observing process. Meanwhile, it has intelligent features of automatic recorded and identified for the driver travel routes. The observation information is collected by the external image sensors of the navigator.
