Research on the Integrity Detection of Aluminum Foil Sealing Based on Infrared Imaging Technology
Zhao Shilong, Li Weijun, Shi Chengjiang
A method for detecting the integrity of aluminum foil seals with high detection accuracy and high detection efficiency is proposed.First of all,in order to obtain the infrared image of the sealing part aluminum foil,the method has adopted the infrared imaging technology.Then,the infrared image is preprocessed and the feature is extracted by circular symmetric Gabor wavelet.Lastly,KNN is used to identify and classify the acquired imaging.Experiments show that the circular symmetric Gabor wavelet used by this sealing detection method has higher recognition rate and faster algorithm than the traditional Gabor transform algorithm, and provides technical assurance for the automatic screening and rejection of defective sealing products in the subsequent aluminum foil sealing production line.
