The invention provides a device, method and system for compensating light and shade cut-off line deviation. The device comprises an optical system, an adjusting mechanism, aircraft equipment and a central processing unit. The optical system projects an illumination light pattern to the front of the vehicle, and the illumination light pattern comprises a cut-off line; the adjusting mechanism adjusts the relative position of the optical system and the relative position of the cut-off line; the aircraft equipment projects the adjusting reference grid to the road surface in front of the vehicle, shoots an image of the relative position of the light and shade cut-off line and the adjusting reference grid, and transmits coordinate data to the central processing unit; and the central processing unit receives coordinate data from the camera device, calculates offset data of the cut-off line, generates a corresponding adjusting instruction to the adjusting mechanism, and compensates the offset of the light and dark cut-off line emitted by the optical system. The offset of the cut-off line is compensated through mutual cooperation of the optical system, the adjusting mechanism and the central processing unit in the aircraft equipment and the vehicle lamp, and automatic adjustment of the cut-off line is achieved.
本发明提供了一种补偿明暗截止线偏移的装置、方法及其系统,包括光学系统、调节机构、飞行器设备及中央处理器;光学系统向车辆前方投射照明光型,照明光型包括明暗截止线;调节机构调整光学系统的相对位置和调节明暗截止线的相对位置;飞行器设备向车辆前方的路面投影调节基准网格和拍摄明暗截止线和调节基准网格相对位置的图像,并将坐标数据传递给中央处理器;中央处理器接收来自摄像装置的坐标数据,计算截止线的偏移数据并生成相应的调节指令给调节机构,对光学系统发出的明暗截止线的偏移进行补偿。本发明通过飞行器设备和车灯内的光学系统、调节机构及中央处理器的相互配合对截止线的偏移进行补偿,实现了截止线的自动调节。
