pad_tactile_read — DRIVE pegtactile op

• Data kinds: table × table → table

• Call: import fullseye as fs; fs.ledger.pad_tactile_read(frame: 'dict', pad: 'dict', ctx=None, track=None, pixelwise: 'bool' = True) -> 'dict' (to call the implementation directly, import pegtactile; pegtactile.pad_tactile_read(frame: 'dict', pad: 'dict', ctx=None, track=None, pixelwise: 'bool' = True) -> 'dict'; from the registry, opsdrive.get("pad_tactile_read"))

Usage

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

パッド 1 枚の像 → (P̂, q̂, ねじり)。

P̂ = 陰影 → photometric の法線(:func:tacsim.membrane_recover)→ 接触半径(中心は既知 = パッド中央;`pixelwise` なら

:func:tacsim.contact_radius_fit_pixelwise、偽ならビン版 :func:tacsim.contact_radius_fit = 罠の対照)→ :func:tacsim.hertz_force。

q̂ = マーカー追跡(:func:tacslip.marker_track、`track` で渡せば省く)→ 法線荷重の ūr(P̂ から閉形式)を引く → 2 成分の Mindlin

当てはめ(:func:tacslip.mindlin_fit_vector)。ねじり = 当てはめたせん断場を引いた残りに、固着核(r < 0.6 â)で剛体回転

(:func:tactorque.rigid_rotation_fit)→ M = (16Gâ³/3)ω(Reissner–Sagoci)。第 2 実装 `Q_stick` = 固着核の一様変位 δ̂ を

Mindlin の δx 式で逆に解いた値(μ は較正値)。返り `P・a・q(2,)・Q・phi・torsion・c_over_a・Q_stick`・

`matched・rms_px(当てはめの残差)・track。**Raises** ValueError: frame に rgb・shading` が無い、追跡できたマーカーが 3 未満。
