METHOD FOR CALCULATING AMOUNT OF CLOUD FROM WHOLE SKY IMAGE AND APPARATUS THEREOF

摘要

The present invention relates to meteorological prediction, and more particularly, to a method and apparatus for predicting solar power generation by calculating and predicting the amount of cloud using an all-sky photograph. The present invention aims at correcting the occurrence of errors in the measurement of cloudiness from the distorted images of all-sky photographs and measuring the accurate cloudiness. In order to realize such a point of view, (For example, dividing a region as shown in FIG. 3), and setting different weights for correcting the distortion of the lens in each region, and calculating (measuring) the cloud according to each region.
