基于三角网格的电磁数据的内插和可视化方法

Interpolation and Visualization Methods of Electromagnetic Data Based on Triangle Grids

研究了从采集的离散点场强生成整个平面区域的场强的插值方法,及生成的场强数据可视化的颜色映射方法。采用基于三角网格的内插技术,先对二维离散点构造三角网格;假定每个三角形的顶点场强、坐标构成一平面空间,三角形内部的未采集点场强可以由顶点决定的场强平面方程插值求得。给出了插值结果可视化的四段制颜色映射解决方案,与目前国际上主流电磁软件颜色映射方式一致。

The method of planar region field density generation from collected scattered data and the color mapping methods of field density visualization were developed, Interpolation technology based on triangle grids was utilized. Two - dimensional scattered points were utilized to construct triangle grids firstly, It was assumed that field intensity and coordinate of each triangle apex form a planar space. Field intensity of points which are not collected can be acquired by interpolating planar equation. The method of color mapping of interpolating results was presented, which is consistent with that of the currently leading electromagnetic software.
