Abstract

The invention discloses an intelligent fish monitoring method based on a video image, and the method comprises the steps of obtaining a fish passing video, carrying out the frame extraction processing, carrying out the noise reduction processing, and inputting the processed video into a trained Faster-RCNN for recognition; judging the central position distance between fishes of the same type in two adjacent frame images so as to determine whether one fish is located on the adjacent frame image or not; and when the same fish is located on the two adjacent frame images, determining the change ofthe number of each type of fish in the fishway based on the relationship between the central position and the reference line of the same fish on the two adjacent frame images and the change amount ofthe central position. According to the scheme, accurate counting of the number of each type of fish can be realized through the mode.

Description

technical field [0001] The invention relates to a method for monitoring underwater targets, in particular to an intelligent monitoring method for fish based on video images. Background technique [0002] In recent years, a large number of various types of hydropower stations have been built in my country. The dams of these stations have caused difficulties for the free migration of fish, especially seasonal and physiological migration, threatening the survival and reproduction of fish. In order to solve this problem, the newly-built dam is specially designed with a fishway for fish to pass through, and uses light, sound and biochemical fish luring technology to try to induce fish to the entrance of the fishway, guide and help them pass through the fishway. [0003] Fishway is a kind of fish passing structure set up at gates, dams or natural obstacles to communicate with fish migration channels. Important indicators. At present, the monitoring of fishways at home and abroad...
