Microstructure Surface Reconstruction from SEM Images: An Alternative to Digital Image Correlation (DIC). (arXiv:2203.13438v1 [cs.GR])

We reconstruct a 3D model of the surface of a material undergoing fatigue
testing and experiencing cracking. Specifically we reconstruct the surface
depth (out of plane intrusions and extrusions) and lateral (in-plane) motion
from multiple views of the sample at the end of the experiment, combined with a
reverse optical flow propagation backwards in time that utilizes interim single
view images. These measurements can be mapped to a material strain tensor which
helps to understand material life and predict failure. …
