container_fill_level — DRIVE granular op

• Data kinds: image2d → table

• Call: import fullseye as fs; fs.ledger.container_fill_level(side, *, threshold: 'float' = 0.5) -> 'dict' (to call the implementation directly, import granular; granular.container_fill_level(side, *, threshold: 'float' = 0.5) -> 'dict'; from the registry, opsdrive.get("container_fill_level"))

Usage

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

容器内側の側面像(粉の被覆率、容器の内寸 = 画像)から充填率と粉面の傾きを読む。

充填率 = 列ごとの粉面(しきい値の交差、副画素)の平均 / 行数。粉面 → `fit_line` →

`surface_tilt_deg(右が高いほど正)と surface_rms`(平面からのずれ [px])。

Raises `ValueError`: 空(しきい値以上の画素が無い)/ 満杯で粉面が見えない(最上行が粉)。
