US 2026/0073561 A1 · METEOROLOGICAL MEASUREMENT DEVICE

Abstract

A maintenance-free meteorological measurement device that can accurately estimate the amount of falling rain, snow, or fog droplets without becoming clogged with debris or evaporation of water. A rain gauge includes a light guide plate and an infrared camera in a housing, and an AI computer that is an information processing device. The housing has a rectangular parallelepiped shape with an open top and an open bottom. The light guide plate unit is mounted on one side surface of the housing. The light guide plate unit includes an LED, a light guide plate, and a diffusion plate housed in a unit case. The infrared camera is on the other side surface of the housing that faces the one side surface across a space. The AI computer detects images of raindrops and estimates the amount of rainfall from the images of the raindrops using machine learning.

Dependent claims

A meteorological measurement device comprising:

a housing having an open top;
a light source on one side surface of the housing and configured to radiate light into a space inside the housing below the top;
an imager on an other side surface of the housing, the other side surface facing the one side surface across the space, and configured to capture an image of the light radiated from the light source;
and
an information processor configured to detect an image of rain, snow, or fog droplets falling through the space via the top and blocking the light radiated from the light source from an image captured by the imaging device, and to learn a correlation between the image detected and a measured amount of falling droplets through machine learning, and estimate the amount of falling droplets from the image.
