Egg freshness nondestructive testing system based on Android system and egg freshness nondestructive testing method

Abstract

The invention provides an egg freshness nondestructive testing system based on an Android system and an egg freshness nondestructive testing method. By utilizing the egg freshness nondestructive testing system and the testing method, a target can be subjected to real-time testing, the speed is high, and the testing accuracy is high. The testing method comprises the following steps: firstly determining whether an egg has a crack, then fractionizing freshness testing to four different testing items of air chamber area, ratio of egg yolk pixel to whole egg pixel, egg yolk ovality and egg yolk deviation, training to obtain effect weight to the freshness of the different testing items, namely a freshness model, and synthesizing to obtain a Half value of the tested egg. By utilizing the egg freshness nondestructive testing system and method, the freshness of the egg can be directly provided, and the egg freshness nondestructive testing system has testing instantaneity and high testing stability and accuracy and is suitable for an egg consumer to use.

Description

technical field [0001] The invention relates to an egg freshness nondestructive detection system based on an Android system and a detection method thereof, and belongs to the technical fields of mobile phone software development, digital image processing and agricultural product detection. Background technique [0002] Eggs have always been one of the agricultural and sideline products with great demand in the Chinese market because of their rich nutrition, convenient eating and diverse cooking methods. During the production, storage, transportation and sales of fresh eggs, the freshness of eggs is easily affected by human and environmental factors, and consumers can only know whether the eggs are fresh if the shell is damaged. The current freshness detection relies on physical and chemical methods such as manual experience detection, egg microbial group analysis, gas elements produced by egg metabolism, and knock vibration analysis. These methods have problems such as time...
