Problems solved by technology

In the actual slaughter workshop, the eye muscle area can only be measured when it is divided into quarters. This process can only be started after the beef is slaughtered and stored in the cold storage for at least one day, which is not conducive to real-time grading.

Abstract

The invention relates to a device and a method for automatically grading beef carcass meat yield based on computer vision. The device comprises a carrying device, a charge coupled device (CCD) digital video, a light-emitting diode (LED) spotlight, a piece of stretchable background cloth, a computer and the like. The method comprises the steps of calibrating the CCD digital video by an Open CV calibration method, and carrying out real-time video capture on a production line of a beef slaughter factory by using a digital camera; automatically identifying half carcass passing through the production line according to the Hough Transform principle, carrying out photograph capturing extraction, and segmenting out a carcass outline area of a captured image by an image processing method; after that, extracting inflection points of the outline by an angle seeking method, and calculating corresponding characteristic values; establishing a beef carcass meat yield prediction model according to the characteristic values and manually weighed cut meat weight; finally, grading the beef carcass according to the model. After the device and the method are adopted, the meat yield of beef carcasses on the production line of the slaughter factory is automatically graded, so that beef yield detection has objectivity, accuracy, real-time property and high efficiency.

Description

technical field [0001] The invention relates to the technical fields of beef carcass meat yield, grade assessment and computer vision, in particular to an automatic grading device and method for beef carcass meat yield based on computer vision. Background technique [0002] In beef processing, the meat yield of the beef carcass determines the price of the beef carcass. Generally, the direct method to evaluate carcass meat yield is to weigh the cut meat after slaughtering and dividing the cattle, but it is time-consuming, laborious and costly in actual operation. If you pay the cattle seller, you can predict the slaughter rate or meat production and other segmentation and slaughter indicators of the cattle, and adjust the price of the cattle according to these relevant indicators, so that the price of the cattle purchased is fair and reasonable, thereby avoiding disputes , so that the economic efficiency of the enterprise has been greatly improved. Therefore, most enterpris...
