The camdkit OpenCV-to-OpenTrackIO note maps OpenCV k1..k6 to interleaved OpenTrackIO l-coefficients scaled by F^2, F^4, F^6 (so a naive k-to-l copy is wrong) and records a correction: earlier versions omitted the half-image principal-point term because OpenCV's origin is the top-left corner. Curator qualifications: Correction date (2025-09-02 per producer) not re-read; direction convention (U undistorts vs OpenCV distorts), unrepresentable terms, 3DE LDPK and Hydra comparisons (F4-F8) not reinspected; 3DE archive not downloaded. OpenLensIO PDF (mm-based units) not reinspected. Static reading only; no tracking data sent or received; no calibration converted. Limitations: Static reading only; no tracking data sent or received; no calibration converted. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
