Description

technical field

[0001] The invention belongs to the technical field of agricultural equipment, and relates to an opening-and-closing intelligent weeding device for acquiring seedling grass information based on binocular vision. Background technique

[0002] Elimination of field weeds is an important part of field management operations. At present, in our country, there are many methods of weeding, and the commonly used weeding methods include artificial weeding, chemical weeding and mechanical weeding. Manual weeding has the disadvantages of high labor intensity, time-consuming and laborious work, and low operating efficiency. Chemical herbicides are highly efficient, but if used improperly, not only will not achieve the expected control effect, but it will damage or even destroy crops, and the residual toxicity of the chemical will cause certain environmental pollution, which is not conducive to the sustainable development of agriculture. Mechanical weeding is more advanc...
