Some noises were added into the 20°/20°zigzag test data, and wavelet threshold denoising method was applied to denoise the polluted test data. The denoised test data were compared with the original test data. It is shown that the wavelet threshold denoising method is effective. Denoising effect can be enhanced by increasing the length of wavelet basis function, and there is an optimal wavelet decomposition level for wavelet basis functions.
