Embodiment Construction

[0034] The present invention is aimed at mechanized weeding operations, and proposes an automatic recognition method based on computer images, an electromechanical control method and an intelligent and precise spraying and weeding device to ensure that the weeding and spraying machine can correctly identify crops and weeds during field operations. And according to the distribution of weeds, the corresponding nozzles are opened in real time and accurately, and the herbicide is sprayed on the weeds, so as to save pesticides and reduce environmental pollution.

[0035] figure 1 It is a functional block diagram of the automatic identification method for weeds of the present invention; the method for automatic identification of field weeds proposed by the present invention comprises the following steps:

[0036] Step 101: The camera equipped at the front of the intelligent sprayer pulled by the tractor acquires images of crops and weeds in the field in real time;

[0037] Step 102...

Abstract

The invention discloses an automatic identification method of weed, including: using pickup camera on the farm machine to collect the real-time images of plant which need to be analyzed in the field, and transmit them into the computer on the machine. The computer stores the images comparison standards from a large number of crops and weeds with application of statistical methods, which is compared with the image of plant that needs analysis though identification method, and determines whether the plant is crop or weed according to the result of analysis, and then control the spraying machine will spray drug aiming at the weed according to the result of comparison. The invention can identify the crop and weed well, and spray drug to the weed exactly according to the distribution, to save pesticide and reduce environment pollution.

Description

technical field [0001] The invention belongs to the technical field of automatic control of agricultural machinery and equipment, and relates to an intelligent operating tool for weeding crops, in particular to an automatic identification method for images of weeds in the field. Background technique [0002] Commonly used mechanized weeding and spraying devices generally cannot perform targeted spraying during field operations, and the spraying amount is not dynamically adjusted. If a certain area is determined to be weeded, a general-purpose mobile spraying device is used to load a large amount of herbicides and spray the entire field. First, a large amount of herbicides is consumed, which makes the use of resources unreasonable. A large amount of drugs remain on crops and cultivated land, which is not conducive to environmental protection. [0003] Herbicide is a powerful magic weapon invented and created by human beings in the struggle against weed hazards. In the late ...
