Aiming to the stroke image on display full of blurs, stroke signal is processed after data acquisition according to the strict time sequence of each signal of stroke and the features of stroke signal frequency distribution in aero display signal. Process brightness signal in binary way and filter stroke deflection signal in sections. The method of Savitzky—Golay filter was chosen, 3σ rule was used to detect outliers and remove it from the data, dynamic design was used in the extent of the smooth window. The results show the effectiveness of proposed method. Using the method, most noises can be removed, the quality of stroke image on display in ATS can be improved greatly.
