Rapid nondestructive detection system and method for freshness of eggs

Abstract

The invention discloses a rapid nondestructive detection system and method for the freshness of eggs and relates to the technical field of nondestructive detection of agricultural products. The rapidnondestructive detection method comprises the following steps: controlling a camera lens module to acquire an images of an egg to be detected by utilizing a single chip microcomputer, and carrying outimage processing analysis to obtain long-axis and short-axis data of the egg; calculating initial mass and volume of the egg through a corresponding mathematical model; meanwhile, measuring current egg weight of the egg through a weighing sensor; finally, importing initial density and current density of the egg into a formula and calculating to obtain the density loss rate of the egg. According to the rapid nondestructive detection system and method, disclosed by the invention, a multi-sensor fusion technology is utilized and rapid nondestructive detection of the freshness of the eggs can befinished; a plurality of models are used for calculating gradually; the models have good linearity and the detection accuracy is high; based on an embedded type system, the high-reliability, extendable and easy-to-upgrade system is simple in structure and low in cost and can be widely applied; the system is small in volume and is easy to carry, is applicable to multiple scenes and is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of non-destructive detection of agricultural products, in particular to a fast non-destructive detection system and method for freshness of eggs, and in particular to multi-sensor fusion density loss rate detection technology and host computer software development technology. Background technique [0002] Eggs are rich in nutrients and are very popular among consumers. my country is a big country in egg production and consumption, and the total output of eggs accounts for more than 40% of the total egg production in the world. The freshness of eggs is not only an important indicator of egg protein, but also closely related to the health of consumers. However, at present, the detection of the freshness of most eggs mainly relies on manual methods, which are easily affected by human subjective factors, and the detection efficiency and accuracy are not high, which cannot meet the needs of modern large-scale an...

Problems solved by technology

[0004] At present, many scholars and experts at home and abroad have actively explored and researched on the detection of egg freshness, but there is still a lack of portable detection device systems for marketization. Traditional detection methods are not high in accuracy and efficiency. Although some new detection methods combined with modern technology can improve the accuracy and efficiency of egg freshness detection, they cannot be widely accepted and used in people's daily life due to their high design cost or difficult operation.
