LCD Product Line Glass Board Real-Time Detect System

With the fast development of modern information technology, the researches and applications of image processing, especially real-time image processing catch great interests from all over the world. And in recent years, the development of LCD technology has put the theory achievement of digital signal processing field into practical application systems. There are lots of LCD Product Lines in our country, however most of these product lines were imported. Especially LCD bug real-time detective system is expensive, so most of our product line didn' t buy this system. There isn' t one similar system developed by our country' s company. Therefore we developed LCD PRODUCT LINE GLASS BOARD REAL-TIME DETECT SYSTEM is significant very much.The dissertation is based on our lab' s research and applications in the field of image processing system.The paper describes the main plan and requirement of the Real-time Detective System, and the capability of key hardware, and the reason we choose the hardware. And then, after analyzing the requirement of our project and the developing procedures of real-time image processing system, the dissertation introduces the functions and the top-level design of the system. We also describe the difference of Image processing arithmetic, explain the reason we choose Laplace as Edge Detective arithmetic.Firstly, the system get original image through CCD vidicon subsystem. Then we deal with these original images using Linear Transform, noise filter, Image Edge Detective, Pattern Recognition, and so on. Finally, through computer serial port, the system chooses enhancing alertsubsystem or not automatically. This method increases efficiency of LCD product line, and ensures the safety of LCD Product Line.The Project has been finished. After testing in our lab, the equipment has been installed in LCD product line of the companys. And the System run excellently, the precision is 100%.
