scoop_volume_read — DRIVE scoop op

• Data kinds: image2d × scalar × scalar × scalar × scalar → table

• Call: import fullseye as fs; fs.ledger.scoop_volume_read(side, rim_row: 'int', a_px: 'float', h_px: 'float', pitch: 'float', *, opaque: 'bool' = True, assume_level: 'bool' = False, heap_min_frac: 'float' = 0.005, level_tol: 'float' = 0.01, rim_full_frac: 'float' = 0.95, fit_angle: 'bool' = True) -> 'dict' (to call the implementation directly, import scoop; scoop.scoop_volume_read(side, rim_row: 'int', a_px: 'float', h_px: 'float', pitch: 'float', *, opaque: 'bool' = True, assume_level: 'bool' = False, heap_min_frac: 'float' = 0.005, level_tol: 'float' = 0.01, rim_full_frac: 'float' = 0.95, fit_angle: 'bool' = True) -> 'dict'; from the registry, opsdrive.get("scoop_volume_read"))

Usage

スプーンの側面像からすくった体積を読む。

• `opaque=True(金属の椀): 縁より下は見えないので、縁より上の山を :func:revolution_volume_side` で測り、

すり切りの閉形式(:func:spoon_bowl_volume)に足す `V = V_struck + V_above`。縁より上に何も無いと、すり切りか

足りないかを側面から区別できない —— `assume_level=True でなければ ValueError`(黙ってすり切りと言わない)。

• `opaque=False(透明な椀・断面の像): 全体を Pappus の形で積分し、すり切りの 1 − level_tol` に満たなければ

`under として深さを閉形式 V_fill(y)` の逆(二分法)で返す(平らな粉面を仮定)。

• `fit_angle: 山が十分大きければ(左右 8 点以上)縁を地面とみなして granular の repose_angle_silhouette` で

山の斜面の角を読む(安息角との照合用、小さな山では `None`)。

返り: `V, V_struck, V_above, state(heaped / level / under)、heap_angle_deg`、

`heap_base_frac(縁の行の山の幅 / 縁の直径)、rim_full(heap_base_frac ≥ rim_full_frac`: 山の裾が縁まで届いている =

椀が縁まで満ちている見込み。届いていない「山になりかけ」は縁の際が満ちきらず、不透明の読みは閉形式の分だけ多く出る ——

MuJoCo で 0.90 のとき +9 %、0.99 のとき +1 %)、`axis_col、fill_depth_px`(透明のとき)。

Raises `ValueError: rim_row が像の外 / 縁より上が空で assume_level` でない(不透明のとき)/ 引数の範囲。
