| titleOfInvention | A kind of BOPP composite film surface coating quality monitoring method |
| abstract | The invention relates to the technical field of image processing, in particular to a method for monitoring the quality of glue coating on the surface of a BOPP composite film. The method includes: selecting the image to be enhanced according to the gray value of the pixel point in the gray image of the BOPP composite film under the illumination of the light source at various angles; dividing the gray image at each angle to obtain each super pixel block set; The gray value of the pixel points in the pixel block set obtains the light source influence degree index. According to the similarity index and the light source influence degree index of any two superpixel blocks in the image to be enhanced, the multi-scale fusion of the image to be enhanced is performed to obtain the intensity of each pixel point. Salient index; enhance the image to be enhanced based on the saliency index; judge the quality of gluing based on the number of edge lines in the enhanced grayscale image and the number of pixels on each edge line. The invention improves the detection accuracy of the glue coating quality of the BOPP composite film. |
