| Abstract: | The x axis and y axis signals of the orbits of shaft centerline to form a radial function are combined. Based on zero crossing representation of wavelet transform of this radial function and matching procedure, a new algorithm to identify orbits of shaft centerline is proposed. Experimental results show that the algorithm can efficiently provide a higher resolution. |
