Embodiment

[0048] Precise feeding methods applied to recirculating aquaculture, including the following:

[0049] Model construction steps: Obtain historical feeding videos, extract key frames from historical feeding videos to obtain training images, and randomly divide training images into test set and training set.

[0050] Mark the residual bait in the training set, train the preset YOLO model according to the marked training set, optimize the trained YOLO model according to the test set to obtain the residual bait identification model, and store the residual bait identification module.

[0051] Mark the outcrops of the cultured organisms in the training set and the cultured organisms on the surface of the water. In this embodiment, the cultured organisms are fish, so the outcrops of the cultured organisms are the fish outcrops in the training images, and the cultured organisms on the surface of the water are the fishes on the water surface in the training images. Train the preset YOL...

Abstract

The invention relates to the technical field of feeding devices, in particular to an accurate feeding system and method applied to recirculating aquaculture, and the method comprises the following steps: a feeding step: obtaining a feeding tentative amount, and feeding according to the feeding tentative amount; a residual feed analysis step: analyzing the water surface image after feeding in real time, and judging whether residual feed exists on the water surface or not according to the water surface image; an aggregation analysis step: when no residual feed exists on the water surface, analyzing the water surface image to generate the aggregation degree of the cultured organisms, and generating the feeding amount according to the aggregation degree; the feeding step further comprises the step of feeding according to the feeding amount; and repeating the residual feed analysis step and the aggregation analysis step. By adopting the scheme, the feeding amount can be controlled for feeding according to the ingestion intensity of the cultured organisms, so that accurate feeding is realized, and the technical problem that the breeding cost is increased due to improper feeding in recirculating aquaculture in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of feeding devices, in particular to a precision feeding system and method applied to circulating aquaculture. Background technique [0002] In the aquaculture industry, it is necessary to feed the cultured organisms. The existing feeding methods usually include the following two types: one is artificial feeding, which mainly throws the bait according to the farming experience and habits, and then controls the amount of bait according to the amount of food intake. Adopting such a method not only consumes a large amount of manpower, but also has high labor intensity. Random throwing will easily lead to serious waste of bait and increase the cost of feeding. The second is to use the feeding machine to feed, and rely on experience to control the timing and quantitative feeding of the feeding machine. Although this solves the manpower problem of feeding, it still requires experienced farmers. Secondly, the feedi...
