| Abstract: | Based on the traditional threshold function in wavelet analysis, combined with the wavelet threshold function proposed by other scholars, this paper further studies and analyzes the practical application. We propose a new method: denoising the deformation monitoring data with a new wavelet threshold de-noising function. Theoretical analysis and examples show that the new wavelet threshold de-noising function can effectively remove noise and has good denoising effect. |

| Keywords: | wavelet threshold function wavelet de-noising deformation monitoring quality assessment |
