Abstract: Disclosed are an automatic leveling system and a method for a headlamp, which accurately detects whether a road is uphill or downhill, and a lateral gradient condition of the road. The system and method also automatically adjust a light radiating direction through the headlamp according to the road. Further, a sensor capable of scanning a road surface and a lamp module radiating light are integrated with each other, so a light irradiation position is accurately and rapidly adjusted according to a road condition, thus improving the accuracy and the reliability of the light irradiation position. Further, as the light irradiation position of a headlamp is adjusted by comparing image capturing information obtained through an image capturing device with sensing information obtained through a laser sensor, the deterioration of the aiming accuracy due to the mounting state of a camera is prevented.
