基于Gear预估校正法的NURBS曲线插补算法研究
Research on NURBS Curve Interpolation Algorithm Based on Gear Prediction Emendation Method
摘要
Abstract
Aiming at the problem of the traditional NURBS curve interpolation methods such as poor real time performance and large velocity fluctuation,a new NURBS curve interpolation algorithm based on Gear prediction emendation method was proposed.Firstly,the Gear linear multi step method was used to estimate the parameter values precisely;and then the preprocessing matrix method was applied to calculate the estimated step length.Af-ter that,the iterative correction was carried out according to the ideal step length obtained from the adaptive speed programming.The simulation results indicated that the proposed method could simplify the calculation of parame-ter interpolation to ensure the real time interpolation.Meanwhile,it could improve the interpolation precision and restrain the velocity fluctuation effectively.关键词
