地图分布式显示方法、装置及拼接墙系统

Distributed type map display method and device and splicing wall system

Abstract

本发明公开了一种地图分布式显示方法、装置及拼接墙系统,所有显示客户端共用一份热点数据,该热点数据存在特定的数据容器内。在添加热点时,每个显示客户端从数据容器中获取对应部分的热点数据并进行渲染显示。如此,减少了显示客户端的内存占用,减轻了网络传输的负载,特别是热点数据量较大时,能明显提高整个系统的显示性能。
The invention discloses a distributed type map display method and device and a splicing wall system. All display client sides share the same hot spot data, and the hot spot data are stored in a specific data container. When a hot spot is added, all client sides obtain hot spot data which correspond to the hot spot from the data container and display the hot spot data in a rendering mode. Therefore, the memory usage of the client sides is reduced, the load of network transmission is relieved, and the display performance of the whole system is improved notably especially when the size of the hot spot data is large.
