Problems solved by technology

In these studies, some are judged based on the RGB color components of the egg during the hatching process, and some are judged based on the contour parameters of the egg. At present, although there are corresponding research papers and patents, these researches and patents are still at the research level , most of the research can only detect one egg, and some of them are detected on a single assembly line. These situations are not consistent with the situation of tray incubation in actual production, and these equipments are immature, and the practicability needs to be further improved

Embodiment 1

[0052] Embodiment 1, poultry fertilized egg detection and screening device based on machine vision

[0053] like figure 1 Shown in -3, the poultry fertilized egg detection and screening device based on machine vision includes: (one) kind egg delivery unit, (two) image acquisition unit, (three) kind egg sorting unit, the structure, function and working process of each unit are specific as follows:

[0054] (1) Egg delivery unit

[0055] It mainly includes: the first stepping motor 17, the first synchronous belt pulley 18, the first synchronous belt 19, the first horizontal moving platform 3, the first slide rail 20, the hatching tray 1, the first single-chip microcomputer 7, and the first support frame 21. The specific structure is as follows:

[0056] The first support frame 21, its body is a cuboid frame such as figure 1 and figure 2 shown;

[0057] A first synchronous belt pulley 18 is respectively fixed at the top four corners of the first support frame 21;

[0058]...

Embodiment 2

[0099] Embodiment 2, to the detection and screening of duck eggs

[0100] Use the poultry fertilized egg detection and screening device based on machine vision in embodiment 1 to carry out, the first horizontal moving platform (3), the sucker device (11) are the model that is applicable to duck eggs, and the poultry egg to be tested is the cherry grain duck egg of white shell , the specific detection method is as follows:

[0101] Step 1, start hatching the poultry eggs to be tested:

[0102] Step 1.1, at room temperature (15°C-40°C), carry out surface disinfection treatment with 75% medical alcohol for the poultry eggs to be tested;

[0103] Step 1.2, put the poultry eggs to be tested into the incubator with the blunt end facing up and the sharp end facing down;

[0104]In step 1.3, hatching is started under conditions of an incubation temperature of 38.0°C and a relative humidity of 55%-65%.

[0105] Step 2, obtain the picture of the development of poultry eggs to be test...

Embodiment 3

[0130] Embodiment 3, detection and screening to eggs

[0131] The poultry egg to be tested used in the present embodiment is Nongda No. 3 egg (eggshell color is white). Use the poultry fertilized egg detection and screening device based on machine vision in embodiment 1 to carry out, the first horizontal moving platform (3), the sucker device (11) are replaced with the model that is suitable for eggs,

[0132] Carry out according to the detection method of embodiment 2, system hardware is constant, but detection parameter is changed as follows:

[0133] Step 1.1, carry out surface disinfection treatment with 0.4g / L potassium permanganate solution for poultry eggs to be tested at room temperature (15°C-40°C);

[0134] Step 1.3, start hatching at an incubation temperature of 37.8°C and a relative humidity of 55%-65%;

[0135] Step 2, obtain the picture of the development of the poultry egg to be tested after being incubated for 5 days in step 1; at this time, after the fertili...

Abstract

The invention relates to a poultry fertilized egg detection and screening device based on machine vision. The device comprises a breeding egg conveying unit, an image acquisition unit and a breeding egg sorting unit; the device mainly applies a machine vision technology and a digital image processing technology; a whole disc of breeding eggs to be detected are detected and the light transmission property of each breeding egg to be detected in an image is extracted; whether each breeding egg to be detected is fertilized or not is judged according to the light transmission property of the breeding eggs to be detected; infertile eggs are sucked through a suction disc by utilizing a vacuum generation technology, so that separation of the infertile eggs and the fertilized eggs is realized. The device provided by the invention can replace artificial egg candling so that the labor intensity of workers is alleviated, and the speed and accuracy of breeding egg detection are improved; more importantly, the device takes a hatching tray in actual production as a foundation and has very high practicability; the device is invented so that an infertile egg detection industry of China reaches a new stage, and the device has important significance on an automation level of agricultural product detection.

Description

technical field [0001] The invention relates to a machine vision-based detection and screening device for fertilized poultry eggs, in particular to use machine vision technology to detect non-fertile eggs from breeding eggs to be tested, and to use vacuum generation technology to realize the removal of non-fertile eggs, which belongs to digital image processing and The field of agricultural product testing technology. Background technique [0002] As we all know, poultry eggs are a kind of nutritious food and occupy an important position in people's daily diet. Taking eggs as an example, every 100 grams of eggs contains 12.7 grams of protein, 11.6 grams of fat, 8 kinds of amino acids necessary for the human body, and many kinds of trace elements necessary for the human body. These nutrients are easy to be digested and absorbed by the human body, so poultry eggs Known as the most ideal natural food. my country has a vast territory, diverse poultry species, and abundant poul...
