Real-time feedback
Camera streams and quality overlays flow live over LiveKit. See coverage, reprojection error and board detection as you move — no capture-then-wait loop.
Intrinsics & extrinsics
Per-camera focal length and distortion, then full 6-DoF pose across the rig via pairwise stereo calibration, anchor chaining and bundle adjustment.
Caliscope-compatible
Exports the same per-camera TOML fields as Caliscope, plus engine-ready JSON (three.js, Blender, Unity, Unreal) — drop the results straight into your pipeline.
Operator wizard
A guided flow — board → cameras → intrinsics → extrinsics (with 3D review) → export — that runs in the browser on desktop, tablet or mobile.
Local & private
Everything runs on the machine your cameras are plugged into — even a headless server — and you drive it from any device on your LAN. No cloud, no data leaving the rig; TLS and tablet access built in.
