Abstract

The invention is applicable to the technical field of industrial detection, and provides a heat-shrinkable film defect detection method and terminal equipment. The method includes acquiring an initial image of a heat-shrinkable film; extracting an image of a corresponding area of the heat-shrinkable film from the initial image as a to-be-detected image; subjecting the to-be-detected image to image shape transformation; extracting characteristic information of the to-be-detected image subjected to image shape transformation, and detecting defects of the heat-shrinkable film according to the extracted characteristic information. The heat-shrinkable film defect detection method and the terminal equipment have the advantages that the image of the heat-shrinkable film is subjected to transformation analysis according to image processing techniques such as located extraction, image transformation and characteristic extraction, the defects, such as gaps and cracks, of the heat-shrinkable film during packaging can be detected conveniently and rapidly, automatic detection of the detects of the heat-shrinkable film can be realized, detection accuracy and reliability can be improved, labor cost can be reduced, and detection efficiency and production efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of industrial detection, and in particular relates to a heat shrinkable film defect detection method and terminal equipment. Background technique [0002] At present, when heat-shrinkable film packaging is performed on the surface of medicine bottles, beverage bottles and other products, it is easy to have defects in heat-shrinkable film packaging and unqualified packaging. Usually, after heat-shrinkable film packaging is performed on the product, it is necessary to manually detect whether there are defects in the heat-shrinkable film packaging. However, manual detection of heat shrinkable film defects often has a high false detection rate, low detection efficiency, and high labor costs for manual detection. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a heat shrinkable film defect detection method and terminal equipment to solve the current problems...
