During optical measurement data processing, multinomial fitting principle is used to estimate param?eters and calculate interpolation, which brings higher block error. According to the problem, recursion spline least square fitting method is proposed. Based on the characteristics of flight target track datum, and with the spline func?tion and recursion idea, the simulation calculations show that the accuracy and calculation speed of the fitting can be improved by the method. It has higher practical value.
