摘　　要：设计了一套产品在线LED颜色自动测试系统,该测试系统由摄像机、计算机硬件和LabVIEW软件平台2部分构成,计算机控制摄像机采集一张标准LED图片作为模板,将需要测试的LED图片进行采集并与之进行比较,完成确定LED个数和每个LED的位置以及完成多个不同颜色的LED自动化判断检测,具有实时显示、保存和回放功能。该测试系统可以一次性完成多个LED的颜色测试,测试时间仅为10 s,测试结果准确,已应用在实际生产中。A set of automatic test system of online products of LED color is designed in this paper. The test system is composed of two parts of a camera,computer hardware and LabVIEW software. Computer controls camera to collect a standard LED image as template. The LED picture need to test is collected and compared with the template. We complete the operation of the identification of the number of the LED and the locations of each LED,identifying each LED＇s color,with real-time display,save and playback functions. The test system can finish testing a plurality of disposable LED＇ s color in one time, the test time is only 10 seconds, and the test results are more accurate than before,in the practical application has a very practical value.
