ValueError when reshaping array with calibrationUtils.py

[PureRandomGit]

I get this error when running the updated script for the mrcal calibrationUtils.py:

$ python3 calibrationUtils.py calibration2.json ./img
Traceback (most recent call last):
  File "calibrationUtils.py", line 237, in <module>
    main()
  File "calibrationUtils.py", line 233, in main
    convert_photon_to_mrcal(args.input, args.output_folder)
  File "calibrationUtils.py", line 210, in convert_photon_to_mrcal
    mrcal_model = __convert_cal_to_mrcal_cameramodel(camera_cal_data)
                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "calibrationUtils.py", line 129, in __convert_cal_to_mrcal_cameramodel
    ).reshape((cal.calobjectSize.width, cal.calobjectSize.height, 3))
      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ValueError: cannot reshape array of size 135 into shape (7,7,3)

I believe its caused by images that do not have all the points of the checkerboard being detected/in frame as when I run it with a calibration that has everything in frame and detected it appears to work fine and generates the cameramodel.

broken calibration file:
calibration2.json
working calibration file:
calibration3.json

Platform:

• Hardware Platform: Orange Pi 5
• PhotonVision Version: v2025.0.0-beta-8
• Camera(s) Used: OV9281

Is this using charuco calibration? I wonder if we are exporting all "fake" points as well.

Yes, this is with charuco cal.
