Crop disease and insect pest detection system and use method thereof

Abstract

The invention relates to a crop disease and insect pest detection system and a use method thereof, and the method comprises the following steps: S100, collecting information of crop crowns by a thermal imaging camera and a multispectral camera, and sending the collected information to an image analysis module and a spectrum analysis module; s200, an image analysis module analyzes and processes the image information sent by the thermal imaging camera, determines the moisture consumption condition of the crop crown, and sends an analysis result to a pest and disease damage judgment module; the spectrum analysis module performs sub-processing on the image information sent by the multispectral camera, determines the spectrum condition of the crop crown, and sends the result to the pest and disease damage judgment module; s300, a pest and disease damage judgment module gives a judgment result according to information sent by the image analysis module and the spectrum analysis module, and if it is judged that the crops have pest and disease damage, relevant information is forwarded to a pest and disease damage recognition module; (S400) carrying out heat treatment; the pest recognition module recognizes specific types of pests, so that the purpose of precisely recognizing the pests is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural information, in particular to a crop disease and insect pest detection system and a method for using the same. Background technique [0002] There are many unfavorable factors in agricultural production, but pests and diseases are one of the most important ones. According to the survey, the annual economic loss caused by crop diseases and insect pests in my country is about tens of billions of dollars. [0003] In traditional agriculture, it is assumed that the farm is isotropic, and management decisions such as the application of pesticides are oriented to the entire farmland, which not only greatly increases the cost, but also easily causes soil compaction and acidification. In fact, the distribution of crop lesions in the farmland has extremely strong spatial differences. Knowing the location of crop diseases and insect pests and carrying out targeted control can effectively reduce costs ...

AI Technical Summary

Problems solved by technology

These methods are costly, low in efficiency, time-consuming, labor-intensive, highly subjective, narrow in coverage, and the results of discrimination depend entirely on the experience of the operator, so it is difficult to apply them on a large scale in precision agriculture.

In addition, the spread of some crop diseases and insect pests is extremely rapid, such as potato late blight, a diseased plant can infect the entire farmland in just a few days, if it is not detected and controlled in time, it will cause huge economic losses
