spline approximation meaning in Chinese
样条逼近/样条拟合
样条函数近似
Examples
- Global b - spline approximation of given data points
样条曲线逼近 - An experiment is carried out to test the feasibility of the spline approximation to calculate the kinematic parameters
试验表明样条插值的方法能够求解出平台一阶、二阶运动学参数。 - 23 bajaj c , xu g . spline approximation of real algebraic surfaces . journal of symbolic computation , 1997 , 23 : 315 - 333
基于向量运算，我们给出了插值曲面的完全显式解，保证了曲面的快速生成。 - This process is as follows : firstly , the data of different section contour and of section line have been obtained by reverse - engineering ; secondly , non - uniform b - spline approximation algorithm is used to fit the discrete data ; then the data have been optimized and reduced by adopting adaptive sampling of key points of the fitted curve based on vertical distance , sequently the adaptive sampling data is transformed into the format of the . ibl file of the famous 3 - d design software pro / e . therefore we reconstruct the surface and a model is generated ; lastly , the effectiveness of the adopted algorithm and modeling approach are demonstrated by the experiments
建模型的过程中，首先运用逆向工程测量方法，获得曲面物体上不同截面轮廓线的测量数据点列，接着对测量数据点进行平滑处理，用最小二乘法求解基于数据点列的控制多边形，以非均匀三次b样条曲线拟合截面轮廓曲线；然后利用基于垂距的数据采样算法，对拟合曲线上的数据点进行重新采样，达到优化数据点的分布及减少描述曲线数据量的目的。
