Issues Getting Calibration Parameters for Single Camera Calibration

[Bamifad]

Hi, I am trying to calibrate for a single camera correlation study with a dot pattern and I am having issues being able to successfully get calibration parameters despite having all the dots recognized across the video frames. When it says to look to the cal.log for details I see no errors or issues. What could be the issue? Any help would be much appreciated. Thanks

What happens if you set the origin offsets to 3 in x and y? Looks like your marker dots are 3 dots in, not 2.

Also, you could upload your cal.log file so I could look at it. Thanks.

For some reason I do not see any cal.log file in the directory where the calibration video is or in the correlation directory. How can I resolve that? Thanks for the response

Also I tried changing the offset but it still didn't work

Check in the hidden .dice folder that gets created in the working directory for the cal.log file.

This is the log file. This run was made with the x, y offset as 2 because it recognized more dots that way for some reason cal.log

This log file is for the x, y offset as 3 cal.log

Hmm...something strange must be going on. Any chance you could post your calibration video somewhere for me to see what's going on?

Yes here it is.

Thanks for the video. There was a bug in the calibration tool for video files where the pose_estimation_index variable wasn't being written to the cal_input.xml file. That is fixed now in this version: https://github.com/dicengine/dice/releases/tag/v3.0-beta.8

See if you can get it working with this updated installer. Sorry about the bug.

Yes, that fixed the issue. Thank you!
