preston_pressure_kernel — DRIVE `polish` op

• Data kinds: scalar × scalar × scalar → image2d

• Call: import fullseye as fs; fs.ledger.preston_pressure_kernel(force: 'float', radius: 'float', res: 'float', kind: 'str' = 'flat', estar=None, normalize: 'bool' = False) -> 'np.ndarray' (to call the implementation directly, import polish; polish.preston_pressure_kernel(force: 'float', radius: 'float', res: 'float', kind: 'str' = 'flat', estar=None, normalize: 'bool' = False) -> 'np.ndarray'; from the registry, opsdrive.get("preston_pressure_kernel"))

Usage

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

工具の下の圧力 [Pa] を画素中心で標本化した窓(奇数 × 奇数、中心の画素が工具の中心)。平板は円の内側で一様 F/(πa²)、

Hertz は p0 √(1 − r²/a²)(`radius = 球の半径 R、estar が要る)。normalize=True` なら Σ p · res² = F に合わせる

(画素で数えた円の面積の誤差を消す。FFT の畳み込みで体積を保つため)。

Raises ValueError: 力・半径・画素が正でない、kind が不明、Hertz で estar が無い、接触半径が 1 画素より小さい。
