Název v původním jazyce

Corrected Signal to noise ratio and Mutual information for accuracy determination in PIV

Popis výsledku v původním jazyce

In this work, we focus on an estimation of the measurement accuracy at each measured point using PIV method, a formulation of a suitable metric of the correlation plane and a definition of the dependency between specific metric and the measurement accuracy using the synthetic test so called Uniform flow test and algorithm called multi - step standard cross - correlation. The main contribution of this work is the correction of known metrics of the correlation plane called Primary peak ratio and Mutual information. The correction of these metrics involves the effect of particle displacements within the interrogation area and the effect of the size and the number of the particles on the evaluation of the metric. The result of this work is the functional dependency defining the relationship between the metric value and the accuracy of the PIV measurement.
