ZHANG Yan, WANG Bao-guang. Study on online detection system for surface quality of cell phone panel[J]. 2010, 29(4): 52-54. DOI: 10.13873/j.1000-97872010.04.017.
Some methods to detect the surface defects of cell phone panel are provided.The online detection system based on black-white area array CCD sensors is designed.Software is designed to contorl the system and realize the algorithm with VC++6.0.After the image of cell phone panel is grabbed by CCD
a series of image processing and analyzing methods such as noise-removing
pattern recognition
feature extraction and so on are used to determine whether it is qualified.Experimental results show that these methods are effective.
