基于Google Earth的人机交互平台设计

分析了Google Earth(GE)的基本概况和应用前景,研究如何在C++平台上对Google Earth客户端进行二次开发.通过软件编程,调用Windows API函数和GE COM API函数将GE视图嵌入到开发平台界面中,实现地图定位、实时坐标获取和地理位置搜索功能,并结合Windows Hook(钩子)机制,实现GE视图放大缩小和绘制轨迹的功能,达到人机交互的目的,满足应用基本需求.所设计的人机交互平台具有三维场景逼真、界面友好、功能丰富等特点.

Design of human-computer interaction platform based on Google Earth

Google Earth （GE） and its application perspective are introduced, and the secondary development of GE client on the C ＋ ＋ platform is carried out. Through software programming, GE view is embedded into the interface of the development platform by calling the Windows API and the GE COM API functions to achieve the functions of map location, getting real-time coordinates and searching geographic locations. Combined with Windows Hook mechanism, the functions of zooming GE view and drawing path have been realized, achieving the purpose of human-computer interaction and meeting the basic requirements of application. Human-computer interaction platform designed has vivid three-dimensional scene, friendly user interface, rich functions, etc.
