reproject — DRIVE balltrack op

• Data kinds: points × matrix × matrix → matrix

• Call: import fullseye as fs; fs.ledger.reproject(points, pose, K) -> 'np.ndarray' (to call the implementation directly, import balltrack; balltrack.reproject(points, pose, K) -> 'np.ndarray'; from the registry, opsdrive.get("reproject"))

Usage

World points (N, 3) → (col, row) as (N, 2) (NaN where depth ≤ 0).

References (sample data, literature)

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
