Apparatus and method for controlling intelligent headlamp

1. An apparatus for controlling a headlamp, comprising:

a capturing unit configured to capture a forward image of a vehicle;

a lamp driving unit configured to independently drive LEDs of the headlamp configured as a matrix LED;

a storage unit configured to store an initial origin point, a changed origin point and an offset for adjusting the position of the headlamp; and

a control unit configured to control the lamp driving unit to turn on the headlamp, detect an origin point from the forward image inputted from the capturing unit, set the offset for adjusting the position of the headlamp by comparing the detected origin point to the initial origin point or the changed origin point stored in the storage unit, and store the changed origin point, newly set to the detected origin point, and the offset in the storage unit.

2. The apparatus of claim 1 , wherein when turning on the headlamp, the control unit turns on the headlamp to emit light in a preset pattern, in order to detect the origin point.

3. The apparatus of claim 1 , wherein the control unit turns on an origin point light source included in the headlamp, and then detects the origin point based on the position of the origin light source.

4. The apparatus of claim 3 , wherein the origin point light source is installed to emit light outside a low-beam area of the headlamp.

5. The apparatus of claim 1 , wherein the control unit stores the changed origin point, newly set based on the detected origin point, according to a result obtained by comparing a position, set by the offset between the initial origin point and the detected origin point, to a position set by the offset between the changed origin point and the detected origin point.

6. The apparatus of claim 1 , wherein the control unit outputs an error message through an output unit, when the detected origin point deviates from a capturing area of the capturing unit.

7. The apparatus of claim 1 , wherein the control unit detects the position of the vehicle in the forward image inputted from the capturing unit, and then controls the lamp driving unit to drive the headlamp based on a position calculated by applying the offset stored in the storage unit.

8. A method for controlling a headlamp, comprising:

controlling, by a control unit, a lamp driving unit to turn on the headlamp;

detecting, by the control unit, an origin point from a forward image inputted from a capturing unit;

setting, by the control unit, an offset for adjusting the position of the headlamp by comparing the detected origin point to an initial origin point or a changed origin point stored in a storage unit; and

storing, by the control unit, the set offset and the changed origin point, newly set based on the detected origin point, in the storage unit.

9. The method of claim 8 , wherein the controlling of the lamp driving unit to turn on the headlamp comprises turning on, by the control unit, the headlamp to emit light in a preset pattern, in order to detect the origin point.

10. The method of claim 8 , wherein the controlling of the lamp driving unit to turn on the headlamp comprises turning on, by the control unit, an origin point light source included in the headlamp.

11. The method of claim 8 , wherein the storing of the set offset and the changed origin point comprises storing, by the control unit, the detected origin point as the changed origin point, according to a result obtained by comparing a position, set by the offset between the initial origin point and the detected origin point, to a position set by the offset between the changed origin point and the detected origin point.

12. The method of claim 8 , wherein the setting of the offset comprises outputting, by the control unit, an error message through an output unit, when the detected origin point deviates from a capturing area of the capturing unit.

13. The method of claim 8 , further comprising detecting, by the control unit, the position of the vehicle in the forward image inputted from the capturing unit, and then controlling the lamp driving unit to drive the headlamp, based on a position calculated by applying the offset stored in the storage unit.
