Digital Image Correlation Engine (DICe)
Digital Image Correlation Engine (DICe)
Are you using the default calibration options in DICe? I'm wondering if you have the same options going to both DICe and OpenCV.
I'm not sure what's going on. That's strange.
I'm still looking into the issue with the checkerboard patterns, but with regards to the feature matching failing on the cross correlation, are you able to share your cal.xml file...
I took a look at the stereo correlation initialization for the images you provided (thanks) and it seems like the calibration may not be very good. Can you upload the...
I took a look at your calibration images and for some reason I too cannot get a good calibration out of OpenCV with the checkerboard pattern. Here are a couple...
In the case of the images provided in checkerboard.zip, the calibration from OpenCV and Matlab are not even close. I would say that even though the OpenCV calibration returns a...
The average epipolar error is the distance (on average) away from the epipolar line that the corresponding point in the stereo image is. If the calibration is perfect, the corresponding...
The 'avg_epipolar_error' parameter is just a diagnostic output from the calibration, it's not used in the cross-correlation. I've taken another look at your images and there are some other issues...
Just an update that the dot target calibration routine in DICe has been substantially updated to address some issues that could have been causing the difference between the native OpenCV...
Not as of yet. We haven't made any improvements here, but I'll post something to this issue if we do.
