Camera Calibration

Versioned calibration records contain camera/lens/mode, resolution/aspect, field of view, orientation, intrinsic matrix, distortion, principal point, focal lengths, method/date/source, quality, residual, constraints, hash, and validity state. Partial and unknown records are allowed.

Levels are metadata-only (approximate), user-measured field of view, and calibration pattern. Values are never fabricated, and calibration is not a safety certification.
