I have tried a variety of speckle patterns and dot sizes, but the Perform DIC Analysis substep within step 2 will not work for me. I am making sure that I am correctly following all the steps before by setting up the DIC parameters and everything. I am unsure what could be causing this issue, as it does not seem code related. For the perform DIC analysis step I select the region and then set a single seed and then it tells me there was a high correlation coefficient between the images. Attached is a screenshot of what I have usually been getting after I press okay on the high correlation coeffecient warning.

What is the stereo angle between these two cameras?
Please send me these two images as well as your calibration images and I'll try to find the problem. From what I see, the speckles and the subset look too large and the view on the right is pointing downwards relative to the one on the left, and not only left-right. This might cause the correlation problem. Also, is there a reason the images are not the same size (the left one looks more narrow)?

Thanks for getting back to me about this! I am actually currently on vacation and will be unable to send you the pictures until July 29th. I will add them as a comment once I am back though. I think that there stereo angle was about 20 degrees. As for the image size, I am unsure why they are different sizes, as I am using the same type of raspberry pi camera to take both pictures. I assumed that was just how it was going to be.

Hi Dana. I am actually currently working on fixing the stability of my camera mounts, as you said the the crooked angle of the pictures could be affecting the issue. After I do that I will send you all the calibration images and pictures if there are still issues. Thank you for your help!
