Digital Image Correlation Engine (DICe)
Digital Image Correlation Engine (DICe)
I have taken a look at your input files and here are a couple observations: 1. The camera angle is quite large (more than 60deg), if it's possible, I would...
Sorry for the delayed response...I thought I had replied to this post already. Yes, that's correct. In stereo the distance between the neighboring subsets used to calculate the VSG strain...
Are you able to upload a few of your calibration images? That would allow me to debug what's going on.

DIC, in general (not just in DICe), depends on image gradients created by the speckle pattern. When the speckle pattern is too sparse, there isn't enough image gradient to get...
Hi EV, I'm a little confused by what you are trying to achieve. I get the impression that you simply want to view the physical displacement field in terms of...
I'm not sure I understand your question exactly. Can you provide some images or a plot that illustrates what you are trying to say? In particular could you be more...
Thanks for providing the pdf. That was helpful. What you are observing only applies to SIGMA. The displacement field and strains are indeed computed with respect to the reference frame...
Which version of DICe are you using? If I run your images from the stack .gif in version 3.0-beta.4 I see nearly the exact same displacement and strain fields from...
Looks like there have been several commits that could have addressed the issue you are seeing: https://github.com/dicengine/dice/search?q=incremental&type=commits If you are using a version of DICe that is older than Apr...
