“…HSV consists of Hue (Hue), which represents the dominant color of the spectrum, which is represented by an angle of 0 degrees to 360 degrees, Saturation (Saturation), which represents the richness of the color, and V(Value) [5], which represents the brightness of the spectrum. The HSV model is a nonlinear, perception-oriented model.…”

This paper first discusses the development status of beef cattle carcass grading and photographic equipment at home and abroad, then carries out the equipment design and model establishment, and finally conducts sensory carcass assessment and grading and environmental simulation detection experiments through experiments, and uses the colorimeter and beef carcass intelligent grading system to detect the color difference L*, a*, b* values of meat samples in different environments, color space RGB and HSV color parameters, compare the influence of different environments on meat color parameters and grading results, and verify the feasibility of beef carcass grading photography equipment. The results show that the overall values of the equipment group are at a stable level and in line with the sensory evaluation, so the beef carcass grading camera equipment can effectively avoid the influence of external objective factors, such as: light and dark, poor light source, limiter and framing distance. At the same time, it reduces the interference of operators in the classification process and other problems such as the subjective negligence of the operator on the classification results. The project design equipment structure is simple and reliable, automation equipment is easy to operate and low cost, the new beef cattle carcass grading photographic equipment, suitable for promotion and mass production into the market, can improve labor production efficiency, promote the development of local enterprises’ meat industry, increase enterprise income, reduce the production cost of enterprises, to promote the standardization and unification of beef cattle industry grading system.
