摘要

PROBLEM TO BE SOLVED: To obtain a particle size of precipitation easily and accurately. An image acquisition unit 32 of a precipitation information processing system 10 acquires an image of a first time and an image of a second time captured by a camera 18 installed facing precipitation from the sky. Then, the precipitation detection unit 34 determines the precipitation between the first time and the second time according to the difference between the image of the first time and the image of the second time acquired by the image acquisition unit 32. To detect. Then, the precipitation calculation unit 36 calculates the volume of the precipitation particles corresponding to the precipitation between the first time and the second time, and calculates the diameter of the sphere corresponding to the volume of the precipitation particles as the particle size of the precipitation particles. To do. [Selection diagram] Fig. 1
