摘要
提出一种适用于线图扫描输入曲线拟合的新方法. 它的基本思想是局部采用二次曲线拟合, 而整体用分段三次B样条拟合, 具有较强的抗干扰能力.
We propose a new method of curve fitting for graphic input. We first divide the original curve into several parts,and use quadratic curve to fit each part. Then we use cubic B-spline to fit the whole curve. The experimental results show that this method has a good capability of disturbance resistance.
