Aims: In the production of high-quality hybrid silkworm eggs, it is very important to accurately divide the silkworm by sex so that the females of one breed are crossed with the males of another and vice versa. The practical implementation of this seemingly simple operation in production conditions is very difficult due to the lack of appropriate equipment and technology, and therefore it has not yet been possible to ensure a clear separation of silkworm eggs by sex. Therefore, the goal was to develop a device for separating silkworm eggs by color with software control based on computer vision.
Place and Duration of Study: Experiments were conducted at the
Scientific Research Institute of Sericulture, Uzbekistan in the period
2019-2020 on eggs of silkworm breeds Belokokonnaya-1, Belokokonnaya-2,
Saniish-8 and Saniish-9.
Methodology: The study and analysis showed that the separation of
silkworm eggs is better carried out by piece-oriented feeding it to recognition
zone, developed on the basis of computer vision using a high-speed web camera.
It is also proposed to use Arduino UNO R3 as a hardware platform. The developed
hardware and software for analysis and processing of data on the determination
of color of eggs of silkworms of the developed device on a stationary platform
is described. The device consists of four main blocks. The first one is designed
for eggs feeding in portions, the second for the sequence of eggs alignment,
the third is to bring these eggs to the estimation zone, where the fourth
analyzes and separates light eggs from dark ones.
Results: When setting up the automation for the selection of light
eggs, the separation error was 6-8%; with the dark silkworm eggs configuration,
the error was in the range of 3 to 5%. A sufficiently high error when selecting
light eggs is caused by the low contrast between the color of light silkworm
eggs and the color of the transporting disk. So, at a high rotation speed, an
egg merges with the background of the disk surface and webcam cannot always
recognize it. Further, we plan to increase the separation accuracy by choosing
a more precise illumination of eggs and an optimal rotation speed for the
transporting disk. The recoverable losses of silkworm eggs were in the range of
1-2%, which corresponds to the required parameters.
Conclusion: The use of the device of such design will ensure
reliability in operation, easiness of maintenance, high performance and
accuracy, as well as eliminate silkworm egg's injuries and even its minimal
losses. It will allow to introduction of new hybrids of the silkworm in
production, and produce non-clogged, 100% hybrid silkworm eggs.
