Abstract

Provided are a simple fish counting device, fish counting method, fish count prediction device, fish count prediction method, fish counting system, and fish count prediction system. The fish counting device is characterized in that it includes: a measurement image acquisition means (11) that acquires multiple measurement images over time for a measurement subject region in a passage region through which a fluid containing fish passes; a fish position acquisition means (21) that acquires the positions of the fish for each of the multiple measurement images; a fish line-of-movement calculation means (22) that, on the basis of the positions of the fish in the multiple measurement images, calculates the line of movement for the fish, that is, the trajectory along which the fish are moving; and a fish counting means (23) that, on the basis of the lines of movement of the fish in the multiple measurement images, counts the number of fish.

Description

technical field [0001] The invention relates to a fish counting device, a fish counting method, a fish number prediction device, a fish number prediction method, a fish counting system and a fish number prediction system. Background technique [0002] For example, in fish farming, it is required to count the delivered fish. Fish are counted by visual inspection or manually, but such counting is laborious. [0003] To solve this problem, Patent Document 1 discloses a device that flows liquid containing fish from the upper side of an inclined passage including a counting portion and counts fish passing through the counting portion. However, the device of Patent Document 1 is expensive and involves costs. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: WO 2013 / 080351 [0007] Therefore, the present invention provides a simple fish counting device, a fish counting method, a fish number prediction device, a fish number prediction method, a...
