The invention discloses an image-based
cloud cover, cloud shape and weather phenomenon inversion device and method, and the method comprises the steps: obtaining a
sky cloud picture based on ground equipment, and making a
data set; then labeling data, manually labeling numerical values of 1-100 in the
sky cloud picture, and dividing a
data set into a
training set, a
verification set and a
test set according to a proportion of 7: 1.5: 1.5; then, carrying out random scaling,
random rotation, random overturning, random
cutting and random
gamma correction preprocessing operation on the
training set, namely, the image; s3, extracting an R channel and a
B channel in the
RGB image in the step S3, constructing a new channel, namely an R /
B channel, based on the R channel and the
B channel, and splicing the R / B channel to the original
RGB image; according to the method, the features can be more fully utilized, and the total calculation amount is reduced; the three
branch tasks can supervise one another, so that the output result is more self-consistent, and the phenomenon that the
cloud cover is 100 in a sunny day is reduced, thereby improving the network precision.
