Specifically regarding the importation of opencv, the readme currently states to import opencv-python, however this does not include the proper files in order to import aruco, which exists in the extended library opencv-contrib-python. I've also added an additional flag ", allow_pickle=True"to the .npz file import in the dualStereoChessboardCalibration.py file, located on line 77. We wasted a lot of time trying to figure out why numpy couldn't parse the .npz file in our python environments and this solved that issue. Special thanks to Alina Christenbury and SafariMonkey from the northstar discord server for working with me on this.

Ah, so the aruco library and opencv-python-contrib aren't actually used in the calibrator; I must have accidentally left the include behind after some experimentation with the ChArUco calibration system. Apologies about that, my bad.
The , allow_pickle=True) flag is a good catch; it seems like somewhat recent versions of NumPy require it.
If you remove the import cv2.aruco as aruco line from the top of the python file and change the readme back, I'll merge it asap.
