Digital Image Correlation Engine (DICe)

The details about the shape functions (and the rest of the gradient-based algorithm) can be found here: https://github.com/dicengine/dice/blob/master/doc/reports/LocalGradientAlgorithm.pdf I'm not sure why you are not getting zero strains in the...

A good reference for these kinds of questions is the Good Practices Guide for DIC found here: https://idics.org/guide/

Is it possible to post the full set of calibration images (or at least 10) so I could do some debugging?

The problem is that the lens distortion model in opencv isn't a good match for the lens distortions in the images provided above. That's what is causing the calibration to...

new installer is up https://github.com/dicengine/dice/releases/tag/v2.0-beta.16

Thanks for pointing this out. I rebuilt DICe using gcc 8.4.0 and it compiled without errors. I was using the following flags: -D CMAKE_CXX_FLAGS:STRING="-lgfortran -Wall -Werror -Wno-deprecated-declarations -Wno-unused-local-typedefs -Wno-literal-suffix" I'm...

I *think* for the most part, the build instructions are quite similar. There haven't been many updates to the dependencies. I took a quick look at the build instructions and...

If you change the calibration image folder to one without any non-alphabetic or numeric characters, the calibration tool should work. (I made a similar comment to the issue reference above)....

Thanks for the heads up. I'll be sure to fix this when we update the compiler for our nightly testing.

Hi Jimmy, the link you have above is for the single camera calibration in OpenCV, DICe uses the stereo calibration tool. They should both give you similar values for the...
