course op• Data kinds: table → image2d
• Call: import fullseye as fs; fs.ledger.course_occupancy(course, cell: 'float' = 0.25, margin: 'float' = 2.0) (to call the implementation directly, import drivecourse; drivecourse.course_occupancy(course, cell: 'float' = 0.25, margin: 'float' = 2.0); from the registry, opsdrive.get("course_occupancy"))
• Return value through the ledger: fullseye.ledger.course_occupancy(...) returns **only the declared out type image2d** (the underlying function also returns auxiliary values). When you need what was dropped, use fullseye.ledger.course_occupancy.raw(...) or call drivecourse.course_occupancy directly.
> This operator's description has not been translated yet. The original text follows as it is.
コース(要素または配置)を占有格子 `(occ bool [row = y, col = x], extent)` に落とす。
走れる領域の外 = True(障害物)。格子は bounds を `margin だけ広げた範囲を cell` で覆い、
各 cell の中心で偶奇判定する。`extent = (xmin, xmax, ymin, ymax)` は格子がちょうど覆う範囲
(xmax = xmin + nx·cell)、row 0 = ymin。占有率は cell → 0 で 1 − 面積/格子面積 に収束する(門)。
Raises `ValueError`: cell ≤ 0、margin < 0、course の形が悪い。
