摘要:

基于计算机视觉技术,设计了冷却猪肉异质肉判别装置。介绍了系统装置的工作原理、工作过程、硬件组成及软件系统功能。硬件系统包括快速测定pH计和图像信息采集装置,软件系统将获得的图像,进行二值化处理、高斯去噪、边缘检测、霍夫变化定位和投影算法来提取目标颜色特征参数,并辅助pH值对冷却猪肉进行判别。验证结果显示,设计的判别装置对白肌(pale, soft, exudative,PSE)肉、异于正常(reddish-pink, firm, nonexudative,RFN)肉、黑干(dark, firm, dry,DFD)肉的判断上可以实现94.0%、96.8%和98.0%的准确判断;不仅具有良好的准确性,而且缩短了处理时间,提高了作业效率。

Abstract:

Color is an important property that influences the consumers’ purchase decision of a food or agricultural product
and its market value. A non-destructive and rapid detection system for assessing chilled pork quality based on computer
vision system was developed. The working principle, process and hardware composition of the system as well as the
software system were introduced. The hardware system included a pH meter and an image collector, and the acquired images
were processed by binarization, Gauss denoising, edge detection and Hough-transform positioning for the extraction of the
characteristics color parameters by projection algorithm. In addition, pH was used to aid in identifying chilled pork quality.
The experimental results showed that the system could be used for distinguishing chilled pork with high accuracy and
reliability as well as good repeatability.

Key words: chilled pork, distinguishing, pH, colorimetric plate
