关于机载显示器中地图显示嵌入式架构的改进

The Betterment of Embedded Structure Used for Map Display in Airplane Monitor

针对传统地图显示系统存在地图画面卡顿、刷新速度变慢的问题,研究了地图显示嵌入式架构的地图数据格式、地图数据解析和地图数据库管理方式,提出了基于SQLite、Mitab的地图显示嵌入式架构。该架构在满足机载显示器系统性能需求的基础上,提高了地图功能的灵活性和更新速率,具有一定的应用价值。

According to the traditional map display system of map screen Caton, slow refresh speed, on the map display in embedded architecture map data format, map data analysis and map database management, we put forward the SQLite Mitab architecture based on embedded map display. On the basis of satisfying the performance requirements of the airborne display system, the architecture im- proves the flexibility and update rate of the map function, and has certain application value.
