摘要
研究了任意控制点B样条曲线小波光顺技术,通过插入节点增加控制点个数的方法,既保持了原有曲线的形状,又满足小波光顺对控制点个数的要求。运用第2代小波变换,给出了B样条曲线的第2代小波变换表示及光顺方法。该方法运算简单,易于推广。
The wavelet fairing technology of arbitrary control point B-spline curve has been studied.By means of method of interposing nodes to increase the number of control points could both maintained the shape of original curve and satisfied requirements on the number of control points for the wavelet smoothing.The expressing and fairing methods for the second generation wavelet transformation of B-spline curve were given out.This method is simple in operation and is prone to be popularized.
