displace_markers — DRIVE tacslip op

• Data kinds: matrix × matrix × matrix × scalar → matrix

• Call: import fullseye as fs; fs.ledger.displace_markers(pts, fx, fy, pitch: 'float') -> 'np.ndarray' (to call the implementation directly, import tacslip; tacslip.displace_markers(pts, fx, fy, pitch: 'float') -> 'np.ndarray'; from the registry, opsdrive.get("displace_markers"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

変位場 fx, fy (n, n) [m] でマーカー中心 (N, 2) [px] を移す(場は中心位置で双線形標本化、画素に換算して足す)。

Raises ValueError: pts が (N, 2) でない、fx と fy の形が違う、pitch ≤ 0。
