摘要
本文介绍了一种以面阵CCD成像技术作为测试方法的汽车前照灯检测仪校准器检定系统。此系统采用多维精密可调工作台 ,利用计算机数字图像处理技术及VC + +编程实现自动测量被测校准器的发光强度、远光光束中心、近光明暗截止线转角坐标以及光轴偏移角等特征参数的目的。其优点是测量精度高 ,重复性好 。
Ameasuring system for calibrators of headlamp tester for motor vehicle using planar array CCD as detector is introduced in the paper. It has multi-dimension precise adjustable workbench,utilizes the computer digital image processing technology, and is programmed with VC++.This system can measure the characteristic parameters automatically, such as luminous intensity, center of far light, corner of close light. The advantage is high accuracy, good repetition and automatic measurement.
