Uncertainty quantification is crucial for any measurement technique. The present work aims at validating a priori estimates of displacement uncertainties. Images acquired prior to fourteen thermomechanical tests were analyzed via FE-based stereocorrelation to determine actual displacement uncertainties, which were compared to a priori estimates. For the studied experimental database, a very good agreement was observed between a priori and a posteriori estimates of standard displacement uncertainties.

关于 T3 立体相关中标准位移不确定性的先验估计的验证

不确定度量化对于任何测量技术都是至关重要的。目前的工作旨在验证位移不确定性的先验估计。通过基于有限元的立体相关分析在 14 次热机械测试之前获得的图像，以确定实际位移的不确定性，并将其与先验估计进行比较。对于所研究的实验数据库，在标准位移不确定性的先验和后验估计之间观察到非常好的一致性。
