摘要
提出了在已知现速度的情况下，用样条函数计算视加速度的新方法，避免了传统牛顿插值法的不可靠性及由此而产生轨道重构错误的缺点，仿真结果表明用样条函数法重构的轨道精度明显优于牛顿插值法。
A new method to calculate visual acceleration by using spline functicn is presentedunder the condition that visual velocity is known. Unreliability caused by the traditional New-ton interplation method and disadvantage of trajectory configuration error from this are avoid-ed. The simulation result shows that the accuracy of trajectory configured with spline functionmethod is much better than that cofigured wish Newton interpolation method.
