Digital Image Correlation Engine (DICe)
Digital Image Correlation Engine (DICe)
We don't have an Ubuntu machine to test on (or detailed install instructions). You'll have to navigate through whatever issues come up on your own.
All you need to do is define a keypoint file (live_plot.dat) and place it in the working directory. DICe will then automatically output the live plot files for those keypoints....
Sorry, I thought you were talking about live plot points when you said "keypoints" but you are asking about supplying the calibration keypoints. If that's the case, ignore my last...
Would it be possible to post one of your calibration images to this issue so I could check that you have the right parameters? (You have the link to your...
Looking at you cal images, it seems you only have images with the calibration target lying on the table. To get a good cal you need images with the calibration...
Making the dots bigger would help since the calibration depends on the center of the dots which gets averaged from the pixels that the dot covers. The distance shouldn't be...
Is it possible that one of the cameras is upside down? It looks that way from the left and right stereo images.
Regarding your first question about the failed correlation, it's probably due to your object not being planar. The default cross-correlation routine in DICe works well for planar objects, but not...
I would try lowering the SSSIG tolerance. It may be that your new pattern doesn't have enough variation in the contrast.
Can you post a screenshot of DICe that shows the areas of the image that get analyzed? That might help narrow down what is going on.
