Description

Technical Field

[0001] The invention relates to the technical field of application of intelligent monitoring equipment for the occurrence of cotton aphids and their natural enemies in cotton fields, and in particular to intelligent counting equipment for aphids and their natural enemies on the upper, middle and lower leaves of a cotton plant. Background Art

[0002] As an important pest on cotton, cotton aphids are not evenly distributed on cotton plants. Cotton aphids may have different distribution densities in different parts of cotton plants due to various factors such as environmental conditions, food sources, and growth stages. The national standard document "Technical Specifications for Cotton Aphid Monitoring and Reporting" clearly stipulates that the occurrence of cotton aphids on a cotton plant can be determined by statistically investigating the occurrence of cotton aphids on the upper, middle, and lower leaves of the cotton plant. The occurrence level of cotton aphids in the entire field can be determined by investigating the occurrence of cotton aphids and their natural enemies on the upper, middle, and lower leaves (a total of 300 leaves) of 100 cotton plants at 5 points in the cotton field, with 20 cotton plants at each point.

[0003] Based on the above standards, during the aphid monitoring period, plant protection personnel will conduct sampling surveys at five points in the cotton fields that need to be monitored. Each point is in charge of a plant protection personnel. Each plant protection personnel selects 20 cotton plants at the point and counts the number of aphids and their natural enemies with the naked eye, and then manually records them on a pre-made form. This traditional survey method is very time-consuming and labor-intensive, with large errors and poor timeliness.

[0004] With the development of computer technology and a new generation of artificial intelligence technology, researchers have proposed using deep learning to train an aphid identification and counting model based on images of aphid occurrence. After taking photos on the spot through the trained model, the model can quickly identify the number of aphids and their natural enemies in the images, thereby quickly and accurately obtaining the occurrence level of aphids and their natural enemies in the monitored cotton fields.

[0005] In the prior art, the three leaves of the upper, middle and lower cotton plants are photographed by using mobile phones or VR glasses in cotton field surveys, and then the images are identified and counted in the cloud or terminal. Although the mobile phone ecosystem and VR glasses are very good, when using mobile phones or VR glasses to take pictures in the cotton field ecosystem, multiple random variables that affect the image data will be introduced invisibly. These random variables mainly include three parts. The first is the random variables caused by the attributes of the mobile terminal itself, such as different mobile phone camera parameters, different shooting habits due to different vision of individuals, etc. The second is the random variables in the cotton field ecosystem, such as cotton plant leaves, aphids and their natural enemies will change with growth and development. The third is the random variables in time and space, such as light, weather and other variables that change all the time. These variable factors directly cause the random complexity of image data to grow exponentially. For this reason, the recognition model trained by images taken by mobile phones or VR glasses will have unstable accuracy when measured in the field.

[0006] Therefore, how to reduce the random complexity of image data taken in cotton field ecosystems so that the complexity of image data can be controlled within a certain range, and then improve the recognition accuracy of aphids and their natural enemies in front-line cotton fields and enhance the accuracy stability, is a technical problem that urgently needs to be solved.

When driven by the motor 11, the motor 11 drives the worm 12 to rotate, and the worm 12 drives the worm wheel 14 and the first gear 15 to rotate.
