According to the characteristics of micro-resonator motion images
wavelet transform is used to extract the micro-resonator motion track features. Based on the blur image synthetic technique
wavelet transform was applied to enhance and abate noise of blur micro-resonator motion images
while the traditional image processing method is used to extract the motion track features
and finally the natural parameter of micro-resonator was acquired as important reference for MEMS design. In comparison with traditional image processing method
wavelet transform method has better measurement resolution
and its measurement repetition error is 100 nm.
