Uncertainty quantification for 3D digital image correlation
Understanding the final uncertainty in position, displacement and strain for digital image correlation (DIC) is a difficult or impossible enterprise when done analytically. In contrast, this paper will present a new approach using a pseudo-experimental method for estimating the 2D matching uncertainty, a Monte Carlo approach for understanding the calibration uncertainty, and the propagation of these error contributions to calculate a final 3D uncertainty. The methodology of calculating the errors will be presented using a sample measurement case. Additionally, the sensitivity of the position and motion errors to the various DIC parameters will be discussed. © The Society for Experimental Mechanics, Inc. 2013.
