摘　　要：自动跟踪型汽车前照灯检测仪是集光、机、电技术于一体的专用仪器设备。它具有自动跟踪光轴,利用图像传感器对灯光图像进行采集,并利用数字图像处理技术对灯光图像进行处理,从而得到多个测量参数的功能,是建立在多学科基础上的综合技术。图像处理是一门与计算机技术、自动化技术、电子技术等相交叉综合的学科,一直是计算机技术发展的重要领域。本文试图从工程应用的角度出发,利用先进的嵌入式系统,深入研究如何快速、准确自动跟踪光轴、对灯光图像进行采集、对汽车前照灯的远近光进行自动检测,以及提高精度和抗干扰技术。The technology of automatic following optical-axis tester for automobile headlamp is a complex technology based on many subjects. It is a special instrument integrated with technology of optics, mechanics and electronics, It has the functions of automatic following optical-axis, using the CMOS image sensor to get the headlamp images, and using the technology of digital image process to get parameters of headlamp. Image processing technology is a comprehensive subject connected with the computer technology, automatic technology., electron technology and so on, It is the important field in the development of the computer. This paper attempts to use the advanced embedded system, deeply research how to automatic follow the optical-axis rapidly and accurately, how to get the headlamp image, how to measure the high and low light of automobile headlight, and how to enhance the accuracy and anti-amming from the view of project application.
