基于虚拟基准轴的不规则曲线的插补算法

The Interpolation Algorithm of Irregular Currve Based on Virtual Datum Axis

用累加弦长参数三次样条拟合不规则曲线，使拟合后的曲线光滑圆顺。然后用累加弦长作为虚拟的插补基准轴，提出了一种基于虚拟基准轴的插补新算法。该插补算法简单、适用、实时性强，插补精度高。

This paper describes the method that the irregular curve is fitted with accumulated chord length parametric cubic spline. The fitted curve is smooth and continuous. The accumulated chord length is used as virtual interpolation datum axis. The new method about irregular curve interpolating is developed, which is simple, applicable and has high and excellent precision.
