Electronic lamp aiming system and method for a vehicle
A lamp aiming method is implemented in an electronic lamp aiming system for a vehicle. In the system and method, a controller recognizes a light distribution area using information of a target in top / bottom / left / right angles in a front image of an image receiver for the target, which is light-distributed to a light source of a head lamp. Another controller adjusts a pixel area of the light source based on the light distribution area to perform aiming correction and to apply the adjusted pixel area to the light distribution of the lamp. Through an electronic aiming structure not using head lamp aiming instruments, direct matching is achieved between the head lamp and a camera, which is required for high-precision aiming. A vehicle attitude can also be determined without sensors by using the secured matching.
