摘要

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
