摘要
根据测量不规则几何形状模具时误差的控制方法,提出了通过限制两型值点间拟合曲线段到两型值点间弦的最大距离来控制拟合精度的有理曲线拟合算法,并与Bezier曲线和参数三次Spline曲线进行了比较。
According to the method of error control in measuring dies and moulds with non-geometric three-dimensional shapes, this paper presents an algorithm for rational curve fitting with control accuracy by limiting the maximum distance from the curve segment to the chord between two knots and comparese it with Bezier cubic curves and parametric cubic Spline curves.
