| The work aims to design a food packaging detection system based on machine vision, in order to improve the appearance and ensure the quality of food packaging. Food packaging detection system mainly included image acquisition module, image processing and analysis module, output execution module and other parts. The key techniques of image processing were discussed. Based on the traditional wavelet transform, an improved algorithm was proposed to enhance the image feature information, improve the recognition rate and realize the edge detection of food packaging. Taking pollution, flying ink and other typical defects as examples, the methods of feature extraction ware discussed, including roundness, aspect ratio, gray standard difference and so on. Finally, an experimental study was carried out. The experimental results showed that, with detection accuracy of more than 99%, the proposed food packaging detection system had relatively high detection accuracy. The food packaging detection system based on the machine vision can meet the requirements of food packaging. |
