Defects detection method and system of TCP and COF by image processing technique

Provided are a method and system for detecting a defect in TCP / COF using an image processing technique. TCP / COF failure detection method using an image processing method according to an embodiment of the present invention, the step of acquiring and filtering and binarizing the reference image of the film; Acquiring, filtering, and binarizing an inspection image of the film passing on the inspection table; Obtaining a difference image between the binarized reference image and the test image; And reading whether the film is defective through the difference image, and performing a labeling process on the difference image. On the other hand, TCP / COF failure detection system using an image processing technique according to an embodiment of the present invention memory unit for storing the reference image of the film; An image acquisition unit for acquiring an inspection image of the film passing on the inspection table; And an image reading unit for obtaining a difference image between the inspection image and the reference image, and performing a labeling process of the difference image.
