A method and a device for recognizing native eggs based on machine vision technology

Abstract

The invention provides a method and a device for recognizing native eggs based on machine vision technology. At first, an egg to be tested is photographed, and the egg shape index, the gray value information entropy and the eggshell surface impurity level of the egg to be tested are calculated according to the photograph, , and then egg shape index, gray value information entropy, and eggshell surface impurity level of the egg to be tested are respectively compared with a reference index range, a reference information entropy, and a reference miscellaneous quality step by step, so as to identify the egg to be tested and judge whether the egg is a native egg or not. The egg shape index, the information entropy of gray value and the impurity level of eggshell surface are obtained by machinevision technology, and then compared with the reference value, the native egg can be recognized quickly and the cost of artificial recognition can be greatly reduced. The purpose of recognition can berealized more effectively and the recognition is more accurate by comparing the characteristics of the egg to be tested.

Description

technical field [0001] The invention relates to the technical field of agricultural product production, in particular to a machine vision technology-based identification method and identification device for native eggs. Background technique [0002] my country is a big egg producer and exporter, and also a big consumer of eggs. As one of the most common foods on people's tables, eggs play an important role in people's daily life because of their high quality and low price. Compared with eggs produced by captive chickens, native eggs produced by native chickens have relatively better quality. Native eggs are deeply loved by the public because of their pollution-free, rich in vitamins, and good taste. Some captive eggs are sold as native eggs in the market, and relying on manual experience to judge native eggs is the usual identification method. When the number of eggs is large, the manual identification method will have problems of low efficiency and high cost . [0003] H...
