An online visual inspection device and method for the internal quality of salted eggs

Abstract

The invention discloses an online visual inspection apparatus and method of the internal quality of a salted egg, and relates to the technical field of salted egg processing grading. The apparatus comprises a salted egg (8), and also comprises a conveyor belt (1), an industrial camera (2), a camera obscura (3), a light source (4), a photoelectric switch (5), a PLC (6) and a computer (7). The method comprises the following steps: 1, acquiring salted egg images; 2, discriminating qualified eggs: 1) pre-treating the salted egg images, 2) extracting characteristic parameters, and 3) discriminating the qualified eggs; and 3, discriminating retreat dissolve eggs and black yolk eggs: 1) afresh pre-treating unqualified salted egg images, 2) extracting the characteristic parameters, and 3) discriminating the black yolk eggs and the retreat dissolve eggs. The apparatus and the method using the machine vision to detect have the advantages of no zinging of application environment, good application and promotion prospect, high efficiency, high intelligence, realization of nondestructive and online detection, and suitableness for detecting and classifying the salted eggs.

Description

technical field [0001] The invention relates to the technical field of salted egg processing and grading, in particular to an online visual inspection device and method for the internal quality of salted eggs. Specifically, the present invention uses machine vision technology to collect color images of salted eggs, and performs a series of image preprocessing to obtain the grayscale parameters of the R and H components in the RGB space and HSV space of the salted egg image, and at the same time breaks the judgment of salty eggs. The category of egg quality is finally determined and graded by using statistics to set thresholds, thereby realizing the detection of the internal quality of salted eggs. Background technique [0002] Salted eggs have always been loved by ordinary people in my country because of their delicate egg quality, loose sandy taste, oily dew and delicious taste. In the process of salted egg processing, with the improvement of people's awareness of the qual...

Problems solved by technology

[0004] After searching, the use of machine vision detection is mainly applied to fresh eggs. The above-mentioned research is either at the forefront of static research, or it is an exploratory research based on a new technology. At present, no internal quality grading technology of salted eggs has been found in China. Sorting equipment, without mature algorithms and technologies, cannot be used in actual production, and has no practical production significance
