摘要：
A method to estimate the uncertainty of each vector in Particle Image Velocimetry measurements by estimating the parameters which contribute to errors in the computed velocity field is discussed. These parameters include particle image diameter, particle density, particle displacement, and velocity gradient. After PIV processing, our code "measures" these parameters and an estimate of the velocity uncertainty is made for each vector in the flow field.
