Recently, Wang Ling, an associate professor at the school of engineering, Nanjing Agricultural University, developed a robot that not only picked cotton, but also quickly and accurately judged it.

The grade will hopefully solve the cotton picking quality from the source.

For farmers, picking cotton is a tough job.

Wang Ling introduced that the labour force invested by artificial cotton accounts for about 50% of the whole production process.

For example, in the Xinjiang Construction Corps, 7 million mu of cotton is planted, and the annual picking cost is nearly 400 million yuan.

Mechanics

Although picking efficiency can be improved a lot, it is easy to cause good and bad.

In order to solve the problem of cotton picking efficiency and quality, Wang Ling and his team began to study cotton picking robots since 2005.

According to the introduction, the researchers first use the CCD digital camera to collect the front of the early, middle and late three periods of "Suzhou cotton 12" 1 - 7 seed cotton

A total of 350, and then through technical processing, the seed cotton image segmentation from the complex background, and using the 14 texture characteristics reflecting the cotton whiteness, yellow and impurity content and 16 shape characteristics reflecting the size and structure of the cotton petal, the seed cotton is identified by maturity and grade classification, and the recognition rate reaches 85.3% and 88.4% respectively.

When picking cotton picking robot, binocular vision camera and image acquisition card are used to collect cotton images, and image processing is done to locate cotton coordinates.

After approaching the plant, the robot picks up through the rotation of the manipulator arm.
