parking_position_check — DRIVE crossing op

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

• Call: import fullseye as fs; fs.ledger.parking_position_check(rear: 'float', front: 'float', zones_result: 'dict') -> 'Dict[str, object]' (to call the implementation directly, import drivecrossing; drivecrossing.parking_position_check(rear: 'float', front: 'float', zones_result: 'dict') -> 'Dict[str, object]'; from the registry, opsdrive.get("parking_position_check"))

Usage

Whether the car body [rear, front] overlaps a no-stopping-or-parking section. zones_result = return value of no_stopping_zones.

返り値: ok、overlap = 重なりの長さの最大 [m]、reasons = 重なった区間の (kind, 号)。端に触れるだけは重ならない。
