| description | To remotely and accurately measure the flow rate from a discharge outlet.SOLUTION: An image acquisition unit 122 acquires a first image representing a predetermined area including a water discharge outlet from which water is discharged, in which each pixel has a pixel value representing the reflectance of a specific first wavelength of light, and a second image in which each pixel has a pixel value representing the reflectance of light at a specific second wavelength. A calculation unit 124 calculates, for each pixel, a calculated value using a difference between the pixel value of the first image and the pixel value of the second image. An estimation unit 126 then estimates the flow rate of water on the basis of a calculated image with the calculated value for each pixel as the pixel value and a pre-learned estimation model for estimating the flow rate of water.SELECTED DRAWING: Figure 10
【課題】本発明は、遠隔で、放流口からの流量を精度よく計測することを目的とする。【解決手段】画像取得部１２２が、水を放流している放流口を含む所定範囲を表す画像であって、各画素が、特定の第１波長の光の反射率を表す画素値を有する第１画像と、各画素が、特定の第２波長の光の反射率を表す画素値を有する第２画像と、を取得する。計算部１２４が、各画素について、第１画像の画素値と第２画像の画素値との差分を用いた計算値を計算する。そして、推定部１２６が、各画素について計算された計算値を画素値とする計算画像と、水の流量を推定するための予め学習された推定モデルとに基づいて、水の流量を推定する。【選択図】図１０ |
