Abstract
A measuring system for calibrators of headlamp tester for motor vehicle is introduced in the paper. It utilizes planar array Charge-coupled Device (CCD)as detector to digitalize the image of lighting area on the screen formed by the perpendicular irradiation of calibrator's lamp. By using computer digital image processing technology programmed with VC++, the system can measure the characteristic parameters automatically, such as luminous intensity, center of far light, corner of near light. The advantage is high accuracy, good repetition and automatic measurement.
