What is realtime-calib?

realtime-calib calibrates a rig of USB cameras in a single live pass: capture, ChArUco/ArUco detection, quality feedback and solve happen in real time. It runs headless in Docker on the machine the cameras are plugged into, and is driven from a web app on any device (phone, tablet, laptop). CPU-only, fully local. Exports Caliscope-compatible TOML and engine-ready JSON for Unity, Unreal, Blender, three.js and ROS.
