摘　　要：阐述三维地形提示告警系统,这是一种增强型地形提示和告警的系统,是航空电子系统导航防撞的必备机载设备。针对大容量地形数据加载和前视地形绘制,为提高系统实时性及实用性,基于嵌入式平台系统对三维地形告警系统算法和三维显示进行了设计和研究,它采用多核处理器技术实现算法运算和地形加载绘制,软件运行基于嵌入式实时操作系统实现。提出一种三维地形加载显示方法对三维地形进行加载显示,设计嵌入式软件对算法进行实现验证。通过实验效果分析,验证地形加载显示算法高效性和系统实时性及实用性。Three-dimensional terrain warning system is a kind of enhanced terrain warning and warning system, and it is the necessary airborne equipment for avionics navigation and collision avoidance. For large-capacity terrain data loading and forward-looking terrain rendering, in order to improve the real-time and practicability of the system, the algorithm and three-dimensional display of three-dimensional terrain warning system are designed and studied based on embedded platform system, multi-core processor technology is adopted to realize algorithm operation and terrain loading and rendering, and the software runs based on embedded real-time operating system. A method of loading and displaying 3D terrain is proposed to load and display 3D terrain, and embedded software is designed to verify the algorithm.Through experimental comparison and analysis, the efficiency of terrain loading and displaying algorithm, real-time performance and practicability of the system are verified.
