3D-DIC execution failure due to bad projection estimation #223

Dear DICe engineers,

I have been using DICe smoothly for a couple of months. It really helped me a lot! Thank you for your fantastic work!

Recently, I got a problem for processing 3D-DIC. It said DICe execution failed during processing cross-correlation between left and right image.

error

This is my first time got this problem in 3D mode. The images quality looks good. I think the problem is not about the noise. I tried to switch the left and right images, but it does not help. I also tested some previous 3D photos, which have more noise, but the program can still process them without any problems. Looks like the problem lies in the photos this time...

Due to the limitation of upload size, I put the photos and calibration files in google drive. You can find it here: https://drive.google.com/drive/folders/1YgI9TKDaEay_XsSDhIMJbptTpNvOtcnR?usp=sharing

Any suggestions would be highly appreciated!

Thank you in advance!

Are you using a region of interest defined around the plate in the images? The problem may be that the background is being picked up in the cross-correlation.

Yes, I used the self-defined ROI in the image, which is just the small region with speckles in the image.

Thanks for the reply!

I am using DICe_setup_v2.0-beta.16-win32-x64, which uploaded June 2020.

See what happens if you update to a more recent version: https://github.com/dicengine/dice/releases/tag/v3.0-beta.3

The cross-correlation routine has been worked on a lot between version 2 and 3.
