Missing files 'acircleboard.svg' and "calibr_poses.xml" in file 'calibration.py' and 'register_calibr_poses.py'

Hello, apprecaite for this wonderful repository first. I found files 'acircleboard.svg' and "calibr_poses.xml" are missing in file 'calibration.py' and 'register_calibr_poses.py'. I am not sure what these two files look like and their roles are. Very appreciate if these two files can be added.

'acircleboard.svg' file is a checkerboard required for calibration. You can generate it by referring : https://github.com/opi-lab/tools/blob/main/notebooks/Calibration_pattern_generation.ipynb. Additionally, you should invert the background color.

Then, you should run 'register_calibr_poses.py' to register the poses of the board in the .xml file. When you run the script you can rotate and translate the board with common Blender controls and then press "F" every time you can capture the pose (rotation and translation). When you finish, you can press "ESC" to save the poses in the .xml.

At the end, you must run the "calibration.py" script. "cimg_path" is the path where the projected fringe images will be saved. Note that this script does not perform a calibration, it only captures the images needed to calibrate. Then, you can use the typical calibration code with openCV.
