Abstract

The invention discloses a nondestructive visual inspection grading method for the internal quality of preserved eggs, and relates to the technical field of preserved egg processing and grading. The method comprises the following steps: 1 setting up a preserved egg image acquisition device; 2, obtaining a preserved egg picture; 3, preprocessing the image and extracting color parameters of the preserved eggs; 4, establishing a classification model; and 5 detecting and judging the quality of preserved eggs. The preserved egg quality is detected and judged by combining the machine vision and the BP neural network, the preserved egg quality is not challenged to the application environment, and the application and popularization prospect is good; the BP neural network has very strong learning capability and linear inseparable problem processing capability, and is high in efficiency and high in intelligence; nondestructive detection can be realized, the accuracy is high, and the method is suitable for detection and classification of preserved eggs.

Description

technical field [0001] The invention relates to the technical field of preserved egg processing and grading, in particular to a method for non-destructive visual detection and grading of the internal quality of preserved eggs. Background technique [0002] Preserved egg, as an original egg processing product in my country, occupies an important position in China's egg industry. It has a unique taste, high nutritional value, and has the effects of cooling and appetizing, antipyretic and fire-fighting; preserved egg tofu, preserved egg salad and fried preserved egg. It is very popular and deeply loved by consumers, and is sold in large quantities at home and abroad. [0003] There are two main methods of making preserved eggs: [0004] 1) Coating method: This method requires mixing together the chemicals needed to make preserved eggs, coating them on the surface of fresh duck eggs, and then sealing the eggs in a container for about 7 weeks to complete; [0005] 2) Soaking met...
