Rainfall time downscaling method and device, computer equipment and storage medium

The invention relates to the technical field of artificial intelligence, in particular to a rainfall time downscaling method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a first rainfall image and a second rainfall image collected at adjacent moments; analyzing the gray value of each pixel point in the first rainfall image and the gray value of each pixel point in the second rainfall image to obtain a rainfall motion vector; determining a target interpolation image corresponding to the to-be-interpolated moment according to the rainfall motion vector, the interpolation interval, a first moment and a first rainfall position corresponding to the first rainfall image, and a second moment and a second rainfall position corresponding to the second rainfall image; and generating a rainfall time downscaling result according to the first rainfall image, the second rainfall image and the target interpolation image. According to the invention, the rainfall con
