This paper discussed the uncertainty analysis method of some SPIV results measured inside the compressor rotor.The convergence characteristics of the SPIV results of the three velocity components
the first-order results(vorticity) and the second-order statistics(the Reynolds stress) were investigated
and the measurement accuracy was analyzed.Then
the analysis of the main influential factors to the measurement accuracy of high-order statistics was carried out.At last
some advices for improving the measurement accuracy of SPIV in turbomachinery were given.
