Displacement Uncertainty Quantifications in T3-Stereocorrelation

Background Uncertainty quantifications are required for any measurement result to be meaningful. Objective The present work aims at deriving and comparing a priori estimates of displacement uncertainties in T3-stereocorrelation setup perform high temperature tests. Methods Images acquired prior the actual experiment (i.e.,at room temperature) were registered using 3-noded triangular elements (T3-stereocorrelation) determine different positions experimental setup. Results then compared their estimates. Conclusions For analyzed experiment, it is shown that noise floor only differed by factor 2 when posteriori measurements standard uncertainties.
