Abstract

The invention discloses an online visual inspection device and method for cracks on the surface of poultry eggs, and relates to the technical field of poultry egg processing and classification. The device is as follows: a dark box (2) is set above the conveyor belt (1), an industrial camera (3) is set in the middle of the top of the dark box (2); a light source (6) is set below the conveyor belt (1), and the light source (6) The poultry eggs (8) placed on the conveyor belt (1) are transmitted through the gap of the conveyor belt (1); the photoelectric switch (7) is set on the inside of the dark box (2); (5) are connected; the single-chip microcomputer (5) and the industrial camera (3) are respectively connected to the computer 4 through data lines. The invention uses machine vision to detect cracks on the surface of poultry eggs, and is not picky about the application environment; a single industrial camera is used to take pictures of poultry eggs at multiple flip angles, with a full detection range and low equipment cost; high efficiency and high intelligence can be realized Non-destructive testing has a good prospect of application and promotion.

Description

technical field [0001] The invention relates to the technical field of poultry egg processing and grading, in particular to an online visual inspection device and method for cracks on the surface of poultry eggs. Background technique [0002] Poultry eggs have very high nutritional value, rich in protein, fat, multivitamins and trace elements, and are one of the important foods in people's daily life. Because the eggshell is thin, it is fragile during transportation. Once cracks appear, bacteria can easily invade the egg, causing corruption and deterioration inside the egg. Such eggs cannot be processed and eaten, and need to be removed in time. [0003] At present, some scholars have conducted research on the detection of cracks on the surface of poultry eggs. Tu Kang (a method and device for detecting the surface quality of poultry eggs, CN200510134902.5) uses the sound signal generated by the impact of the elastic percussion rod on the surface of the eggshell and the ima...
