Description

Technical Field

[0001] The invention relates to the technical field of laser weeders, in particular to an intelligent laser weeder. Background Art

[0002] Manual weeding is the removal of weeds by hand tools or manual labor. This method is suitable for small areas or places where it is difficult to use machinery. The advantage is that it can eradicate small weeds, but the disadvantage is low efficiency and high cost. Chemical weeding is the use of chemical agents to kill weeds. This method can quickly and effectively control the growth of weeds, but it will have adverse effects on the environment and crops. To solve this problem, an intelligent laser weeding robot has been developed. The intelligent laser weeding robot is an innovative device that accurately identifies weeds through AI and uses laser technology to accurately remove weeds. It is equipped with a laser head, a lighting lamp and a high-resolution camera, and supports automatic mode and manual mode. In automatic mode, no human intervention is required; in manual mode, the remote control panel can be used to actively control the machine's travel path, plan weed removal operations, and monitor the machine status in real time. Through high-speed photography and artificial intelligence technology, weeds and crops can be accurately identified, and lasers are used to irradiate weeds, causing the moisture on the surface of the grass leaves to evaporate rapidly, and the liquid in the grass cells to vaporize and expand, causing the grass tissue to rupture, thereby achieving a weeding effect.
