Multi-camera calibration part 2

This project extends the work from the previous year, which included basic algorithms for multi-camera calibration, by adding testing cases with wider coverage, refining the algorithm to be comparable to the Kalibr tool, and improving the API to make it more accessible to users. Additionally, it plans to create improved documentation to guide users with little background knowledge in camera calibration. The overall goal is to provide a reliable and robust implementation of camera calibration algorithms in a multi-camera setup.
