Study on Visual Detection Device of Plant Leaf Disease

In order to resist the erosion of corn diseases, researchers have done many experiments and accumulated a lot of experiences. These experiences are not only practical, which used embedded system technology, computational reasoning technology, parallel computing, fuzzy reasoning technology, image recognition, internet of things technology, database technology and other related technologies are combined together, these acquired professional knowledge can effectively prevent and treat corn diseases. Therefore, it is necessary to widely spread these knowledges in order to truly treat corn diseases effectively for prevention and control. However, in many corn disease identification methods, only one type of disease in corn lesions can be identified. When corns are infected with multiple lesions, the lesions that appear after the superposition are not accurately recognized and thus delayed. The treatment of corn diseases caused a reduction in the production of corn and caused serious economic losses to farmers.
