摘要
现代汽车上广泛采用了平面显示器显示一些驾驶信息,对其逻辑显示状态必须进行视觉检测。本研究采取了基于VB和VC图像处理的方法设计测试系统。该系统利用CAN总线通讯模块实现平面显示器的控制,利用摄像头采集图像,并把采集到的图像和标准图片比对。从结果来看,产品的测试正确性在99.8%以上,实践证明此方法实现了对平面显示器的快速自动化检测,是一种行之有效的方法。
The plane monitor is widely used in the modem automobile to display some drive information, and visual inspection must be done for its logic display. This research uses VB and VC image processing to design the test system. It controls the momitor via CAN communication, and it uses camera to collect the picture, then it compares the picture with the standard picture.According to the result, the product test correctness is above 99.8%. This method realizes quick and automatic test for the plane monitor and it is a effective method.
