摘要:

设计了一种汽车日行灯自动测试系统。该系统主要由工业计算机、高性能数字摄像机硬件平台和LabVIEW软件平台两部分构成。采用摄像机拍摄一张标准日行灯图片作为模板,对待测试的日行灯进行图像采集且与模板比较。由模板定位出测试窗口,然后对各个窗口进行RGB模型分析和HSL模型分析,从而完成对日行灯颜色和明度的检测。此外,系统可同时对多个窗口进行分析,并可实时显示测试画面和测试结果,一次测试时间不超过6 s,且准确度和重复性较好,已在实际中应用。

关键词: LabVIEW, 日行灯, 图像处理, 虚拟仪器

Abstract:

A set of daytime running lamp in head lamp automatic test system is designed in this paper.The test system consists of an industrial computer,a high performance digital camera hardware platform and an NI LabVIEW software platform.The industrial computer controls the camera to acquire image from a standard DRL as a template,and acquire the image of daytime running lamps to be tested and compare to the template.The test window is located by the template.The RGB model and HSL model analyses are made for each window to get the color and brightness of daytime running light.The system can simultaneously analyze multiple windows,and display in real-time the test images and results with a cycle time less than 6 seconds,and very good accuracy and repeatability.This system has been applied in practice.

Key words: LabVIEW;daytime running light;image processing;virtual instruments
