sphere_cap_height — DRIVE tacscalib op

• Data kinds: any × any × scalar × scalar × scalar → table

• Call: import fullseye as fs; fs.ledger.sphere_cap_height(shape, centre, a_px: 'float', R_px: 'float', pitch: 'float') -> 'dict' (to call the implementation directly, import tacscalib; tacscalib.sphere_cap_height(shape, centre, a_px: 'float', R_px: 'float', pitch: 'float') -> 'dict'; from the registry, opsdrive.get("sphere_cap_height"))

Usage

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

幾何学的な押し込み(弾性の裾なし)の真の高さ: 接触円の内側 h(r) = −(√(R² − r²) − √(R² − a²))、外側 0(a は min(a, R))。

返り: `h (H, W) [m]、delta(中心の深さ [m] = R − √(R² − a²))、shape_rel`(h(r) − h(0) = R − √(R² − r²) [m]、a に

依らない形、外側は nan)、`r [px]。pitch` [m/px]。

Raises `ValueError`: shape・centre の形、a・R・pitch ≤ 0。
