ttc_from_range — DRIVE `ttc` op

• Data kinds: none → scalar (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.ttc_from_range(distance: 'float', closing_speed: 'float') -> 'float' (to call the implementation directly, import drivettc; drivettc.ttc_from_range(distance: 'float', closing_speed: 'float') -> 'float'; from the registry, opsdrive.get("ttc_from_range"))

Usage

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

距離と閉じる速さから τ = d / v(秒)。世界の姿勢から出す真値(v ≤ 0 なら `inf、d < 0 は ValueError`)。
