keypoint op• Data kinds: keypoints → keypoints
• Call: import fullseye as fs; fs.ledger.keypoints_rowcol_to_uv(keypoints) (to call the implementation directly, import reprconv; reprconv.keypoints_rowcol_to_uv(keypoints); from the registry, opsreprconv.get("keypoints_rowcol_to_uv"))
• GPU: none (CPU reference implementation only)
Image points (row, col) → (u, v) = (col, row). The bridge between the two conventions of the keypoints sort.

keypoints 型には 2 つの軸の約束が同居している(実測): calib.project_3d_point などは (row, col)、project_points / dlt_pose / pnp_ransac は (u, v) = (列, 行)。取り違えても例外は出ず、姿勢が鏡に映ったように出る(W2 の実測: t = (−0.565, 0.61, 3.21) のはずが (0.1, −0.05, 3.0))。列を入れ替えるだけだが、どちらの向きかを op 名に書くため
逆向きの keypoints_uv_to_rowcol と 2 本に分けてある(中身は同じ入れ替え)。
Args:
keypoints: (N, 2) の (row, col)。
Returns:
(N, 2) float64 の (u, v)。
Raises:
ValueError: (N, 2) でない / 非有限 / 空。
