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
