Method and system for removing weeds from farmland

Abstract

The embodiment of the invention provides a method and a system for removing weeds from a farmland. The method comprises the steps that the farmland image is inputted to the trained support vector machine so as to identify the crop area in the farmland image, and the remaining area after eliminating the crop area acts as the weed area in the farmland image; if the judgment result indicates that theweed area exists in the farmland image, the location information of the real weeds in the real farmland is acquired according to the proportional relation between the farmland image and the corresponding real farmland of the farmland image and the location of the weed area in the farmland image; and the real weeds are removed according to the location information of the real weeds. The weed areain the farmland image is identified through the support vector machine and identification is rapid and accurate so that the weeds in the real farmland can be timely and accurately removed and the damage to the ecological environment can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of agricultural weeding, in particular to a method and system for removing weeds in farmland. Background technique [0002] With the development of Internet technology and various information technologies, my country's agricultural development model has begun to transform from the original traditional agriculture to modern precision agriculture. For example, in order to protect the ecological environment and improve the quality and yield of crops, weeds in farmland need to be sprayed precisely. That is, through machines such as fertilizer spreaders, weeds are sprayed automatically, quickly and accurately. [0003] In the farmland where peanut seedlings are planted, there are many furrows, and the furrows are usually covered with dense amaranth. This weed seriously affects the early growth of peanut seedlings and takes away a large amount of soil for planting peanut seedlings. Nutr...
