STK三维场景构建及优化方法研究

Research on Building and Optimizing Methods of STK 3D Scenario

针对STK(Satellite Tool Kit)软件在军事任务可视化仿真领域中的广泛应用,为充分挖掘其显示潜能,重点解决了影响其三维场景构建的瓶颈问题,即三维场景数据格式的转换和数据的获取优化。在分析构建STK三维场景所需要素及其作用的基础上,分别对地形、地表纹理、三维模型和GIS等四类数据格式进行分析,并利用多种辅助软件,系统地提出了由较通用格式数据向STK所支持格式数据的转换方法,以及在对各类原始数据的获取和转换过程中出现的问题进行处理的优化方法。最后通过实例验证表明该数据格式转换方法和数据优化方法行之有效,三维场景显示效果逼真。

According to the far-ranging application of STK （Satellite Tool Kit） in the visualized simulation of military mission, in order to fully dig the display potential, the Bottleneck problem that affected the 3D scenario building was mainly solved, which was the format conversion of 3D scenario data and the obtainment of original data. Based on the analysis of the STK 3D scenario components and function, the data formats about the terrain, satellite imagery, 3D model and GIS data were separately analyzed, and many assistant software was utilized to systematically present the conversion methods from general format data to STK supporting format data, and the optimization methods that arose during the process of obtaining various original data and the format conversion. Finally, through the example, it is shown that the data format conversion methods and data optimization methods are effective, and 3D scenario display effect is amazingly real.
