摘要
重点分析了当前导航电子地图数据更新的两种主要方法:离线版本式更新法和在线增量式更新方法,并着重介绍了使用增量更新方法提供车载导航电子地图在线增量更新服务的ActMap(Actual and Dynamic Map)系统及其所采用的相关更新机制和技术方法。最后通过对上述两种方法的比较,指出在线增量式更新方法是导航电子地图更新的主流趋势。
This paper analyzed the characters of off-line full update method and on-line incremental update method. Then it introduced a successful example named ActMap (Actual and Dynamic Map) using on-line incremental update method, and described the apphed related new mechanism and technical method. Finally, based on the comparison of the two methods, it concluded that the on-line incremental update method is main technique trend of updating the electronic map for vehicle navigation.
