Embodiment 1

[0060] The LSTM network is used to classify the combination of 10 characteristic bands, as shown in Table 1, the Landsat8 multispectral image with a spatial resolution of 30m is used as the experimental data, and the Landsat8 original data has 6 different bands, namely blue band, green band band, red band, near-infrared band, short-wave infrared 1 with a band range of 1.560-1.651um, and short-wave infrared 2 with a band range of 2.1-2.3um (Table 1). The experimental area is located in Nong'an City, Jilin Province ( figure 1 ), and the surrounding crops are densely planted, mostly rice, corn, soybeans and other common crops in Northeast China. After investigation and verification, the experimental area was attacked by insects in 2012. Therefore use the Landsat8 data on August 9th, 2012 to verify the effectiveness of the present invention's method for monitoring crop pests, with reference to the overall flow chart of this example ( figure 2 ).

Abstract

The invention discloses a crop pest monitoring method based on a multispectral remote sensing image of deep learning, and belongs to the technical field of satellite remote sensing image processing and application. The objective of the invention is to solve the problems of poor timeliness of crop pest monitoring, unstable single-index spectral information, difficulty in acquiring hyperspectral unmanned aerial vehicle data and the like in the existing method. According to the invention, combination of ten groups of characteristic band spectrums is adopted. An LSTM long short-term memory network is constructed. Crop insect pest disasters can be automatically and efficiently identified from the multispectral satellite remote sensing image, and certain technical support is provided for the fields of agricultural production disaster prediction and prevention, agricultural insurance claim settlement and the like. The method has the advantages that the crop insect pest disasters can be automatically and efficiently identified from the multispectral satellite remote sensing image;

Description

technical field [0001] The invention belongs to the technical field of satellite remote sensing image processing and application. Background technique [0002] Crop pests are the number one natural biological disaster that threatens the yield and quality of crops, and are easily affected by many factors such as crop varieties, crop planting methods, and growth environments. In recent years, severe global climate changes have provided a good growth environment for the hatching of pests. Large-scale outbreaks of pests have greatly threatened the normal growth of crops, leading to increasingly prominent global food production security issues. For a long time, in order to monitor the scope and degree of occurrence of crop diseases and insect pests, the method of field investigation by plant protection personnel has been mainly used. This method has a certain degree of authenticity, but it has the disadvantages of time-consuming, laborious and poor timeliness. With the rapid dev...
