对于所有需要对地图进行高帧位处理的应用软件系统来说,地形可视化都是一个重要且难度较大的问题,比如飞行仿真,地基飞行测试的同步传感器仿真以及本文重点研究的机场终端区可视化方案等等。就我们目前掌握的技术来看,难点主要在于依赖于视觉的空间模型和坐标变换,需要使用足够高效率的算法和程序实现。本文提供了一个可以建立空间结构和实现坐标变换的算法模型,保证了帧传输错误率在可控范围以内,较大地提高了帧转化效率。
Terrain visualization is an important and difficult issue for all application software systems that require high framing of the map, such as flight simulation, simultaneous sensor simulation of ground-based flight testing, and visualization of airport terminal areas that are the focus of this paper Programs and more. In terms of the technologies we currently possess, the main difficulty lies in relying on visual spatial models and coordinate transformations, which need to be implemented using sufficiently efficient algorithms and procedures. This paper provides an algorithm model that can establish the spatial structure and coordinate transformation, which ensures that the frame transmission error rate is within the controllable range and greatly improves the frame conversion efficiency.
