Abstract

This invention relates to beef measurement method and its apparatus, which comprises image acquisition hardware part and software part, wherein the hardware is composed of shining system, cameral devices, image collection device and computer. The shining system comprises fluorescence lamp source, shining box, diffusion coating and high frequency fluorescence lamp ballast. The information is sent to computer through image collection device and the computer extracts the quality characteristics information of the image and gives the final grade of the beef according to the above information.

Description

Technical field [0001] The invention relates to a detection method and device for beef, in particular to a computer vision detection and grading method and device for beef carcass quality. Background technique [0002] my country's agricultural and livestock products are seriously mixed in the market, which is an important reason for the low added value of my country's agricultural and livestock products, slow agricultural value-added and low international share. Beef is an important animal product, and the beef carcass grade standard plays an important role in guiding beef production and beef price. The United States has formulated beef carcass grade standards since the 1920s, and Canada, Japan, Australia and Europe have also formulated their own beef carcass grade standards very early. China’s existing beef carcass grade standards were established by the Ministry of Agriculture in 2003. Promulgated industry standard (NY / T676-2003). Beef carcass grading is based on the be...
