| Abstract: | Based on the denoising of nonlinear wavelet transform threshold value method,the deformation monitoring data is denoising.Indicated as the processing result of the simulated data and based on denoising of nonlinear wavelet transform threshold value method,the traditional threshold value is compared.The denoising of nonlinear wavelet transform threshold value method can effectively remove the Pseudo-Gibbs phenomenon,enhance the signal to noise ratio,eliminate noise in the deformation monitoring data,distinguish useful signal which is neglected by the noise. |
| Keywords: | wavelet denoising of nonlinear wavelet transform threshold value method deformation monitoring |
