1. A detection device calibration method comprising:
attaching a first reflector to at least one surface of side surfaces of a vehicle such that a reflection surface of the first reflector is perpendicular to a vehicle width direction;
adjusting a direction of a laser marker such that a first laser beam emitted by the laser marker is emitted perpendicularly to the reflection surface of the first reflector;
adjusting a direction of a second reflector disposed in front of or behind the vehicle such that a second laser beam emitted by the laser marker is emitted perpendicularly to a reflection surface of the second reflector, the second laser beam being emitted perpendicularly to the first laser beam in a vehicle length direction;
emitting a detection wave from a detection device provided in the vehicle to the second reflector; and
calibrating a transmission direction of the detection wave based on a detection result of a reflected wave.
