PDP 패턴검사를 위한 영상처리 시스템의 구현 = Implementation of an Image Processing System for PDP Pattern Inspection

다국어 초록 (Multilingual Abstract)

Various defects are found in PDP manufacturing process. So detecting these defects early and reprocessing them is an important factor that reduces the cost of production.
In this paper, the image processing system for the PDP pattern inspection is designed and implemented using the high performance and accuracy CCD line scan camera. For the preprocessing of the high speed line image data, the Image Processing Part (IPP) is designed and implemented using high performance DSP, FIFO and FPGA. Also, the Data Management and System Control part are implemented using ARM processor to control many IPP and cameras and to provide remote users with processed data.
For evaluating implemented system, experiment environment which has an area camera for reviewing and moving shelf is made. Experimental results showed that proposed system was quite successful.
