Abstract
(EN)
This fish counting system (3) comprises: an image acquisition unit (30) that acquires a plurality of images obtained by capturing, over time, images of a photographing area in which a fluid including a fish (1) flows; an extraction unit (31) that extracts a fish in each image; and a counting unit (34) that counts the number of fish. The photographing area has a first area (Ar1) and a second area (Ar2). The counting unit (34) counts the fish when the fish in the first area (Ar1) moves to the second area (Ar2).
(FR)
L'invention concerne un système de comptage de poissons (3) qui comprend : une unité d'acquisition d'image (30) qui acquiert une pluralité d'images obtenues par capture, dans le temps, d'images d'une zone de photographie dans laquelle s'écoule un fluide comprenant un poisson (1) ; une unité d'extraction (31) qui extrait un poisson dans chaque image ; et une unité de comptage (34) qui compte le nombre de poissons. La zone de photographie présente une première zone (Ar1) et une deuxième zone (Ar2). L'unité de comptage (34) compte le poisson lorsque le poisson dans la première zone (Ar1) se déplace vers la deuxième zone (Ar2).
(JA)
魚計数システム(3)は、魚(1)を含む流体が流れる撮影領域を経時的に撮影した複数枚の画像を取得する画像取得部(30)と、各々の画像について魚を抽出する抽出部(31)と、魚の数を計数する計数部(34)と、を備える。撮影領域は、第1領域(Ar1)および第2領域(Ar2)を有する。計数部(34)は、第1領域(Ar1)にいた魚が第2領域(Ar2)に移動した場合に、魚を計数する。
