Positioning method, controller and removing device for removing the top center of cotton

Abstract

The invention provides a positioning method, a controller and a removing device for removing the top center of cotton, wherein, the method comprises the following steps: obtaining color image data anddepth image data of a cotton plant to be removed from the top center; inputting the color image data into a pre-trained depth learning recognition network model to recognize the cotton top center andobtain pixel coordinates of the cotton top center in the color image, generating the depth learning recognition network model by pre-training according to a plurality of top-core cotton plant samplesto be removed, determining three-dimensional spatial position information of the cotton top center according to pixel coordinates of the cotton top center in the color image and the depth image data;wherein the three-dimensional spatial position information is used for positioning the positioning mechanism of cotton top center removal. The technical scheme improves the precision and efficiency of cotton top center removal.

Description

technical field [0001] The invention relates to the technical field of cotton top core removal, in particular to a positioning method, controller and removal device for cotton top core removal. Background technique [0002] Cotton topping is an important link in cotton production. By topping cotton, it removes the top advantage of cotton, promotes the growth of side buds, and makes the plant more dense. At the same time, it can promote branch expansion and prevent lodging caused by vigorous growth. Contribute to multi-knot cotton bolls and increase yield. [0003] At present, the main cotton topping methods include manual topping, mechanical topping, and chemical topping: [0004] 1. The most traditional manual topping method has high quality and little damage to cotton. Therefore, so far, this method is still the most commonly used topping method. However, as the working population in our country decreases year by year, the transfer of agricultural practitioners to other ...

AI Technical Summary

Problems solved by technology

However, as the working population in our country decreases year by year, the transfer of agricultural practitioners to other industries is becoming more and more serious, and the phenomenon of labor shortage is becoming more and more prominent, which in turn leads to high wages and high planting costs.

[0005] 2. The topping of chemical drugs is greatly affected by unforeseen factors such as external conditions, the application technology is difficult, it is difficult to control the best application time, and there is some pollution to the environment

However, limited by the traditional image recognition method's high environmental requirements, harsh lighting conditions, poor recognition effect and stability, and the instability and inaccuracy of the topping mechanism, the topping effect still cannot meet the needs of practical applications.

[0007] Therefore, the existing mechanical topping technology cannot meet the application requirements of cotton mechanical topping operations, such as the inability to accurately identify the cotton top center and its position, resulting in problems such as inconvenient implementation of precise cotton top center removal, low operating efficiency, and poor results.

[0008] For the above problems, no effective solutions have been proposed so far
