Satellite image analysis model generation method and system for calculating solar radiation using artificial neural network technique

摘要

The present invention is a method for generating a satellite image analysis model, comprising the steps of: (a) obtaining a first correlation equation for calculating an insolation amount before a horizontal plane in Cheoncheon based on a first parameter affecting an insolation amount before a horizontal plane in Cheongcheon; (b) Using the cloud index determined based on the ground reflectance and the cloud reflectance corresponding to the lower limit and upper limit of the dynamic range of the solar radiation and the measured value of each pixel of the satellite image before the horizontal plane in Cheongcheon, Obtaining a second correlation between the solar radiation and the cloud index; And (c) obtaining a third correlation equation for calculating the total amount of solar radiation based on the second parameter that affects the cloud index and the atmospheric reflectance.
