Abstract: To explore the machine vision model that can quickly and accurately identify all the colors of smoked chicken legs during the smoking process, this article builds an Xception-CNN model for the recognition of smoked chicken leg colors based on machine vision technology, while compares and analyzes the Xception-CNN model’s recognition effect on smoked chicken leg color by applying ResNet-50, Inception and traditional CNN and other three models.A total of 4 352 smoked chicken leg images of different colors were collected and image pre-processed as experimental samples of four models, of which 3 482 were randomly selected as the training group, and the remaining 870 as the test group.The average recognition accuracy of the four models is Xception-CNN-92%, ResNet-50-91%, Inception-89%, traditional CNN-87%, and test time is Xception-CNN-1.36 s, ResNet-50-0.81 s, Inception-0.98 s, traditional CNN-2.48 s.Therefore, the Xception-CNN model has the highest color recognition accuracy for sugar-smoked chicken leg images, reaching 92%.The test time is slightly higher than the ResNet-50 model and the Inception model, but lower than the traditional CNN model.It only takes 1.36 s to complete the recognition.The fast and accurate identification of the color of smoked chicken legs can provide a reliable basis for the precise control of the parameters of the sugar smoked process and the standardization of product colors.
