Abstract
Inclinometer is used to measure roll and pitch angles in laser target system of TBM. A synthetic method based on wavelet analysis is proposed to decrease the measurement error of inclinometer under great vibration, improving the accuracy of TBM attitude angles. It is applied to reduce edge effect based on signal extension and orthogonal polynomials extension of approximate coefficients. Different denoising parameters are chosen to get minimum error according to the characteristic of the signal. Experiment shows that the proposed method is more effective and versatile than average calculation method used in the field and traditional wavelet denoising method, and the error is compensated less than 1mrad.
