摘要

为快速精准识别糖熏鸡腿在熏制过程中产生的所有颜色,基于机器视觉技术,构建Xception-CNN模型用于熏鸡腿颜色的识别,同时应用ResNet-50、Inception和传统卷积神经网络(convolutional neural networks,CNN)等3种模型对比分析Xception-CNN模型对熏鸡腿颜色的识别效果。采集并经过图像预处理后,共得到不同颜色的熏鸡腿图像4 352张,作为4种模型的实验样本,随机选取其中的3 482张作为训练组,剩下的870张作为测试组。结果表明,4种模型的平均识别准确率分别为92%(Xception-CNN)、91%(ResNet-50)、89%(Inception)、87%(传统CNN);测试时间分别为1.36 s(Xception-CNN)、0.81 s(ResNet-50)、0.98 s(Inception)、2.48 s(传统CNN)。Xception-CNN模型对糖熏鸡腿图像的颜色识别准确率最高,达到92%,测试时间略高于ResNet-50模型和Inception模型,但低于传统CNN模型,仅需1.36 s即可完成识别,此模型可以实现糖熏鸡腿颜色的快速精准识别,为糖熏工艺参数精准调控、保障产品颜色标准化等提供可靠依据。

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.
