Chicken breast lignification degree grading system and grading method based on image deformation characteristics

Abstract

The invention discloses chicken breast lignification degree grading system and grading method based on image deformation characteristics. The grading system comprises a hardware module controlled by an industrial personal computer, a characteristic parameter extraction module and a lignification grading module, wherein the hardware module comprises a CCD industrial camera, a laser ranging device,an LED white light source, a trigger sensor, an air booster pump, a high-pressure air nozzle, a fixing bracket and a baffle; the characteristic parameter extraction module extracts five characteristicparameters related to the chicken breast height; the lignification grading module performs modeling prediction by a BP neural network model according to the characteristic parameters obtained by thecharacteristic parameter extraction and analysis module. The grading method judges the lignification degree of chicken breast according to the characteristic change of the chicken breast before and after high-pressure air injection; the grading system and the grading method disclosed by the invention realize online nondestructive rapid detection of the lignification grade of chicken breast.

Description

technical field [0001] The invention relates to detection and determination of the quality grade of chicken breast meat, belonging to the field of agricultural product processing and intelligent detection and classification, in particular to a method for classifying the lignification degree of chicken breast meat based on image deformation characteristics. Background technique [0002] In recent years, global poultry meat consumption has shown a rapid growth trend. The consumption trend of poultry meat has gradually shifted from whole chicken consumption to cut products and deep-processed products. Among them, chicken breast has become a favorite meat product of consumers because of its rich nutritional value, uniform appearance and color, easy to cook and affordable price. As the market demand continues to increase, the poultry industry meets the market demand by raising broiler breeds with high meat yield and rapid growth. Today, broilers have been raised for half as lon...
