Description

technical field [0001] The invention relates to the field of image recognition, in particular to a method for recognizing crop diseases based on remote sensing images. Background technique [0002] Crop disease is one of the main agricultural disasters in my country. It has the characteristics of various types, great impact and frequent outbreaks. It not only causes losses to crop production, but also poses a threat to food safety. Therefore, the diagnosis and identification of crop diseases play an important role in ensuring crop yield and preventing food safety. At the same time, realizing accurate detection of crop diseases and the determination of the degree of disease is the key to the prevention and control of crop diseases. At present, the traditional crop disease identification mainly relies on the experience accumulated by farmers in the agricultural production process to make judgments, which is time-consuming and labor-intensive, and the real-time and accuracy a...
