CalibLedger

CalibLedger is a web + desktop app for robotics teams to manage sensor fusion calibration like a controlled engineering process, not a pile of scripts. It ingests ROS bag files and calibration outputs (camera intrinsics/extrinsics, IMU biases, LiDAR-camera transforms), then versions them with metadata: robot serial, sensor firmware, temperature range, mounting revision, and validation metrics. The app runs repeatable validation checks (time sync sanity, reprojection error trends, IMU noise estimates, map alignment residuals) and flags regressions before field deployment. It generates a “calibration bill of materials” for each robot build and provides an audit trail for when something changes (sensor replacement, bracket tweak, firmware update). This is not a magic auto-calibrator; it’s a pragmatic system that reduces rework, finger-pointing, and costly field failures by making calibration and fusion parameters traceable, comparable, and reviewable.
