The paper analyzed the principle of the open-close filter and the close-open filter in the mathematical morphology filtering.Based on the noise feature of the piezoelectric gyroscope and how to select method of the structure element,structure elements of the half-circle,triangle and the cosine were used to make up a paralleling complex morphology filter.The static signal and dynamics measurement from a piezoelectric gyroscope was simulated.Comparison result between the wavelet transformation and the morphology filtering showed that the morphology filtering can improve Signal-to-Noise Ratio(SNR) of the output signal,speed of the signal processing procedure.It is easy for the hardware implementation.
