realtime-calib v0.1.0 is out — the first public release. It's real-time, headless multi-camera calibration you drive from your desktop or tablet: recover every camera's intrinsics and 6-DoF extrinsics in one live pass, then export in the convention your target project actually uses.
I'm a freelance computer-vision developer with a PhD in human-movement science, and I build applied technology for health, physical activity and sports performance. This is the story of why I ended up writing my own multi-camera calibration tool — and why I open-sourced it.
realtime-calib now has a public home. This site collects everything you need to install the app, run a calibration, and understand the method — plus the project's open-source licensing.
