Embodiment Construction

[0023] Provide specific embodiments below in conjunction with accompanying drawings.

[0024] Such as figure 1 As shown, a machine vision-based mechanical weeding recognition method for corn seedlings is operated according to the following steps,

[0025] a. The collected RGB image is binarized according to the color features, and the area where the green component is greater than the red component and the blue component is taken as the foreground area, that is, the green plant area, and the others are the background area, and then the binarized image Perform denoising processing and perform connected domain marking on the foreground region in the denoised image;

[0026] b. Convert the RGB model to the HSV model to obtain a saturation image and a chroma image respectively;

[0027] c. Establish a saturation energy model, define the saturation energy of an area as the sum of the squares of the deviations of the saturation and the saturation mean of all points in the area, us...

Abstract

The invention discloses a corn seedling stage mechanical weeding recognition method and device based on machine vision, and belongs to the field of agricultural engineering. The method comprises the following steps of acquiring images by an identification camera, transmitting the images to a processor; according to the corn seedling stage mechanical weeding recognition method based on machine vision, recognizing a corn plant area, measuring and calculating corn root position information and then collecting an executing mechanism to act, so that a rotary weeding knife with a notch rotates around the corn root, weeds around a corn plant are removed, and path navigation of a weeding device is achieved through a navigation camera. The invention provides a high-precision and high-speed mechanical weeding recognition algorithm, realizes autonomous and efficient operation of the weeding device, and has relatively high practical value.

Description

technical field [0001] The invention relates to a method and device for identifying mechanical weeding, belonging to the field of agricultural engineering, and in particular to a method and device for identifying mechanical weeding at the seedling stage of corn based on machine vision. Background technique [0002] Weeds are extremely harmful to the growth of crops. They compete with crops for fertilizer, light, water, and space, and are prone to breed diseases and insect pests, thereby reducing crop yield and quality. The existing weeding methods include artificial weeding, mechanical weeding, chemical weeding, biological weeding, flame weeding, electric weeding, radiation weeding and so on. Among them, mechanical weeding can not only effectively resist the use of pesticides and chemical fertilizers, meet the requirements of organic production systems and the general public for food safety and environmental protection, but also increase the air permeability and water permea...
