摘要
针对计算机模拟非接触式动态板形检测信号 ,基于 Daubechies子波 ,运用子波包理论有效地去除了有害噪声 ,运用多分辨分析理论准确地提取了真实板形信号 ,提高了检测精度 ,丰富了板形及控制理论。
Non ontact dynamic flatness detection signal is simulantly produced first.Harmful noise is successfully removed by Daubechies Wavelet Packets later.Correct signal is precisely obtained by Daubechies Multiscale Analisis in the end.It improves detection accuracy and enriches flatness control theory.
