Abstract

The invention discloses a model training method and a crop yield estimation method. The method includes: obtaining sample normalized vegetation index NDVI, sample soil moisture SM, sample medium resolution imaging spectrometer MODIS remote sensing data and sample crop yield; according to sample NDVI, sample SM and sample MODIS remote sensing data, determine each growing period of crops The corresponding NDVI and SM respectively; according to the corresponding NDVI and SM of each growing period of crops and the sample crop yield, the yield estimation model is trained, which improves the crop yield estimation accuracy.

Description

technical field [0001] The invention belongs to the technical field of satellite remote sensing data, and in particular relates to a model training method and a crop yield estimation method. Background technique [0002] In order to scientifically formulate plans for the import and export of agricultural products, regulate the grain market, and guide the adjustment of planting structures, it is necessary to carry out accurate and timely monitoring and evaluation of regional grain crop yields. As the main food crops, crops can accurately and timely predict the output of crops, so as to ensure the stable and high yield of crops and ensure food security. [0003] At present, the estimation of crop yield mainly uses historical meteorological data and satellite remote sensing data. However, historical meteorological data has a strong regionality, and historical meteorological data in different regions varies greatly. Therefore, using historical meteorological data and satellite ...
