Vehicle headlamp device aiming method and vehicle headlamp device aiming system

A vehicle headlamp device aiming system comprising:

• an in-vehicle camera configured to acquire a front image of an own vehicle;
• a headlamp device configured to emit a specific light distribution pattern in front of the own vehicle;
• and
• a control device configured to control a light distribution pattern of the headlamp device, based on the front image of the own vehicle acquired by the in-vehicle camera, wherein
• the control device is configured to illuminate an aiming screen with the specific light distribution pattern in the headlamp device, acquire an image of the specific light distribution pattern by the in-vehicle camera, obtain coordinates of a specific position in the specific light distribution pattern, by using coordinates set on the image of the in-vehicle camera, and perform optical axis adjustment of the headlamp device to eliminate a deviation with respect to adjusted coordinates of the specific position.
