lateral 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.time_to_line_crossing(offset: 'float', heading_error: 'float', curvature: 'float', speed: 'float', *, line_offset: 'float', lane_curvature: 'float' = 0.0) -> 'float' (to call the implementation directly, import drivelateral; drivelateral.time_to_line_crossing(offset: 'float', heading_error: 'float', curvature: 'float', speed: 'float', *, line_offset: 'float', lane_curvature: 'float' = 0.0) -> 'float'; from the registry, opsdrive.get("time_to_line_crossing"))
> This operator's description has not been translated yet. The original text follows as it is.
TLC: 車(の基準点)が今の曲率のまま円(または直線)を走るとして、車線の境界に届くまでの時間 [s]。
座標: 車線の中心線の上の点を原点、中心線の向きを +x、左を +y。車は (0, `offset`)、中心線に対する向き
`heading_error、曲率 curvature(左が正)。境界は中心線から横 line_offset`(左が正)の線 —— 中心線が
曲率 `lane_curvature の円なら、それと同心の円。届かなければ inf`。
Raises `ValueError`: 非有限、v ≤ 0、車がすでに境界の外側(offset と line_offset の関係で判断)。
