Fish quantity counting system and method based on underwater video

Abstract

The invention discloses a fish quantity counting system and method based on an underwater video, and the system comprises a counting mechanism, the counting mechanism comprises two L-shaped plates which are symmetrically arranged, the opposite inner side walls of the two L-shaped plates are fixedly connected with first detection plates, the first detection plates and the inner side walls of the L-shaped plates are respectively provided with a first sliding groove and a second sliding groove, and the first sliding groove and the second sliding groove are connected with a camera. A second detection plate is slidably connected in the first sliding groove, a lifting plate is slidably connected in the second sliding groove, the lifting plate is fixedly connected with the second detection plate, and a lifting mechanism used for lifting the two lifting plates is arranged between the two L-shaped plates; and a plurality of underwater cameras are fixedly mounted at one ends, far away from the L-shaped plate, of the first detection plate and the second detection plate. The fish counting device is good in fish counting effect, high in counting accuracy, capable of being adjusted according to the width and the water depth of the fishway and wide in application range.

Description

technical field [0001] The invention relates to the technical field of underwater monitoring and counting, in particular to an underwater video-based fish counting system and method thereof. Background technique [0002] The construction of water conservancy and hydropower projects usually has adverse effects on aquatic ecology, especially on fish. The main manifestation is that the construction of dams has caused river channel obstruction, resulting in the compression of the living environment of fish resources, thus affecting the genetic normality of fish resources. exchange, eventually leading to the gradual depletion and disappearance of fish stocks. In order to alleviate this adverse effect, fish passing facilities, such as fishways, fish ladders, and imitation natural passages, are usually installed during the construction of water conservancy and hydropower projects. The number of fish passing up or down the dam in the fish passing facility is an important indicator ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the accuracy of counting in the prior art is low and it is easy to affect the health of fish, and the applicability of the counting equipment is small , and proposed a fish counting system and method based on underwater video
