AI Technical Summary
Existing food packaging sealing inspection devices cannot effectively detect minute and subtle defects, such as wrinkles, broken edges, and oil stains, and the inspection cost is high, failing to meet food safety and quality requirements.
Using machine vision technology, coarse and fine localization are performed by acquiring food packaging images. Combined with pre-built detection and segmentation models, defects in the sealing area are detected, including defect segmentation in the coarse localization sealing area and defect verification in the fine localization sealing area, and valid defects are screened out.
It improves the accuracy of food packaging sealing quality inspection, reduces the rate of missed detection, and can effectively detect minor sealing defects, ensuring food safety and quality.
