| Summary: | 碩士 === 淡江大學 === 資訊工程學系碩士班 === 99 === Panel in the production process, it may be non-uniform on the panel points of light and dark, where is the flaw. On the detection of defects, mainly based on manual inspection currently, it need to rely on a large number of human, and because of the instability caused by the subjective standard detection, it also brings the performance of limited panel production, if automatic detection system architecture, it can reduce the human, and detect the standard stable, thus enhance the production efficiency. In this paper, purpose is to design non-uniform light LCD screen dark spot (MURA) method automatically detects, and then used in LCD production line automatic inspection system. This paper presents, using image processing methods, point defects and the background to enhance the image contrast, thus the use of edge detection methods to detect defects in point of the region.
