This is the calibration tool from my bigger project TrafficLab 3D. Its main use is Inverse Perspective Mapping (IPM) for a traffic CCTV / Webcam and its satellite image to establish a 2-way projection between them.
The produced results include calibration data (distortion, homography...), camera pose, scale, and more, are stored as "G-projection" .json files.
For more context, check out my broader blog post on TrafficLab 3D and find the sections about "G-Projection".
I also have a Guide Youtube Video for TrafficLab 3D that do covers how to use this tool.
For now, its mostly manual work, I extracted this module into a separate repo to hopefully be able to improve this process with more robust math and automated methods.
If you have any suggestions / proposed improvements, open an issue/pull request!
