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.
