Beginner Question: Understanding calibration pipeline and possible improvements

[AditiGaure]

Hello 👋

I am a student currently exploring computer vision and camera calibration using Python and OpenCV.

I went through the repository and README, and I am trying to understand the full calibration pipeline (intrinsic/extrinsic calibration and usage flow).

I had a few beginner questions:

1. Is there any recommended example or dataset to better understand the calibration workflow?
2. Are there any small improvements, documentation updates, or beginner-friendly issues where I could contribute?
3. Would improving comments, examples, or README sections be helpful for this project?

I am very interested in learning and contributing to this repository and would appreciate any guidance on where I can start.

Thank you for maintaining this project 🙏
