| 摘 要： | 针对现有测试系统采集复现的笔划画面不清晰的问题,根据航空显示信号中笔划信号各分量之间时序关系及频率分布特征,对笔划采集数据进行处理。对其中辉亮信号采用二值处理,对笔划偏转信号进行分段滤波。采用Savitzky-Golay滤波数据处理算法,引入3σ准则对异常点进行剔除,并对平滑窗口宽度采用动态设计。仿真实验结果表明,该方法可以消除大部分噪声的干扰,使测试系统复现出的笔划画面质量大幅改善。

| Abstract: | The reproduced stroke image on display is usually not clear,thus we processed the stroke signal after data acquisition according to the strict time sequence of each signal of stroke and the features of stroke signal frequency distribution.The brightness signal was processed by using binary image processing method,and the stroke deflection signal was filtered in segmentations.The method of Savitzky Golay filter was adopted,and 3σ rule was introduced to detect outliers and remove them from the data.The width of the smooth window was designed dynamically.The results of simulation show that the method can eliminate most of the noises and can improve the quality of reproduced stroke image on display in ATS greatly. |
