人体经脉循行路线曲线拟合算法研究

Research on Curve Fitting of Transmission Route of Human Meridian

经络的研究已经证实了循经感传现象的存在,为有效地解决循经感传现象的计算机实时仿真问题,在计算机图形学中的几何曲线构造方法的基础上,提出了以Catmu ll-Rom三次样条曲线的插值方程来拟合经脉循行路线的算法。该算法结合数据库技术,利用已知的穴位点作为经脉循行路线的控制点,通过优化的Catmu ll-Rom插值点的生成算法,计算得到整条循行路线的插值点并连接即生成3维空间曲线。实验结果表明,该算法能够快速地用计算机重构出经脉循行路线,保持了中医理论中经脉循行路线的形态特征。

The modem research in meridian has verified that the phenomenon of meridian＇s route is in existence. It is important to visualize the meridian＇s route interactively in real time. This paper analyses the geometric curve construction and proposes a method to fit transmission route of human meridian using the equation of Catmull-Rom cubie splines interpolation. The method uses 3D acupuncture points as the curve control points. The interpolation data of the whole transmission route is obtained through the Catmull-Rom interpolation algorithm. Experimental results show that this method can reconstruct transmission route of human meridian quickly and maintain the original property well.
