According to the accuracy requirement of detecting printing defects,this paper designed a distributed detection system based on computer vision. This system was mainly composed of image acquisition module,image processing module,input and output module. At the same time,this paper studied some related algorithms of image prepossessing,feature extraction,image registration,image matching and defect detection. The experiment results clearly show that this system and those image algorithms adopted can accurately calculate various characteristic parameters and determine types of different defects and can meet the requirement of the inspection of printing flaws.
