SAME FISH DETERMINATION DEVICE, FISH COUNTING DEVICE, MOBILE TERMINAL FOR FISH COUNTING, SAME FISH DETERMINATION METHOD, FISH COUNTING METHOD, NUMBER OF FISH ESTIMATION DEVICE, NUMBER OF FISH ESTIMATION METHOD, SAME FISH DETERMINATION SYSTEM, FISH COUNTING SYSTEM AND NUMBER OF FISH ESTIMATION SYSTEM
PROBLEM TO BE SOLVED: To provide a simple same fish determination device, a fish counting device, a mobile terminal for fish counting, the same fish determination method, a fish counting method, the number of fish estimation device, the number of fish estimation method, the same fish determination system, a fish counting system and the number of fish estimation system.SOLUTION: Measurement image acquisition means 11 acquires n-pieces of measurement images with time concerning a measuring object area in a passage area where the fluid containing fish passes. Fish position information acquisition means 131 acquires the position information of the fish concerning the n-pieces of measurement images. Fish estimation position information acquisition means 132 selects at least one selection image from the measurement images before the m-1 th among the n-pieces of measurement images, and acquires the estimated position information of the fish in the m-th measurement image assumed to be the position of the fish in the m-th measurement image, based on the position information of the fish in the selection image. The same fish determination means 133 determines that the fish in the m-th measurement image is the same fish as the fish in the selection image, based on the information when the position information of the fish coincides with the estimated position information of the fish.SELECTED DRAWING: Figure 1【課題】簡易な同一魚判定装置、魚計数装置、魚計数用携帯端末、同一魚判定方法、魚計数方法、魚数予測装置、魚数予測方法、同一魚判定システム、魚計数システムおよび魚数予測システムを提供する。【解決手段】計測画像取得手段１１は魚を含む流体が通過する通過領域における計測対象領域について、経時的にｎ枚の計測画像を取得し、魚位置情報取得手段１３１はｎ枚の計測画像について、魚の位置情報を取得し、魚予測位置情報取得手段１３２はｎ枚の計測画像のうち、ｍ－１枚目以前の計測画像から少なくとも１つの選択画像を選択し、選択画像における魚の位置情報に基づき、ｍ枚目の計測画像における魚の位置であると仮定したｍ枚目の計測画像における魚の予測位置情報を取得し、同一魚判定手段１３３は、これらの情報に基づき、魚の位置情報が前記魚の予測位置情報と一致する場合、ｍ枚目の計測画像における魚が選択画像における魚と同じ魚であると判定する。【選択図】図１
