通信车系统空间场强分布的图形可视化实现

Graphic Visualization for Electromagnetic Intensity Data in Vehicular Communication System

针对通信车系统电磁兼容仿真分析软件中电磁数据场的图形可视化,提出了场强彩色云图的生成方法。该方法首先对面元进行四叉树离散,得到满足图形显示精度要求的离散元;然后通过双线性插值求出离散元的场强值;以此为基础建立场强值与颜色值的映射,确定离散元的显示颜色;最后基于通用图形平台和AVI技术,编程实现了场强云图的动态显示。工程应用表明,该方法具有满意的可视化效果。

A method for building color maps of the electromagnetic intensity data is proposed for the graphic visualization of the electromagnetic intensity data in the emulation analysis software of vehicular communication system. First, each surface cell is dispersed by using four - furcated - tree method to get desired precise cell. Then, the electromagnetic intensity data are obtained using bi - directional interpolate method, based on which the mapping between the electromagnetic intensity data and color is established. Finally, dynamic display of the map of electromagnetic intensity data is realized through programming based on general graphic platform and AVI technology. The project applications show that this method can achieve satisfactory effect in visualization.
