A device and method for intelligent feeding of fish fry in greenhouses based on machine vision technology

Abstract

The invention provides an intelligent greenhouse fish fry feeding device and method based on machine vision technology, and belongs to the technical field of greenhouse fish fry breeding and feeding. Cameras are installed on the inner wall of the breeding pond and directly above the feeding area to collect video information of fish schools, and transmit them to the digital signal processor for preprocessing to obtain clear images of fish schools, and send them to the server for processing to obtain the optical flow trajectory of fish schools. The optical flow trajectory of the fish school is input into the discriminant model to judge the current feeding state of the fish school, and then send instructions to the PLC to control the working status of the bin auger, transport auger, and fan to achieve precise variable feeding. The entire feeding process is more intelligent, without manual participation, saving manpower and material resources, and has better economic benefits; it can determine scientific and reasonable feed amount and feeding time, save feed cost, and realize intelligent and accurate fry breeding production Variable feeding promotes the process of high-efficiency farming, economic farming, and ecological farming in fishery production.

Description

technical field [0001] The invention belongs to the technical field of greenhouse fish fry breeding and feeding, and in particular relates to a greenhouse fish fry intelligent feeding device and method based on machine vision technology. Background technique [0002] Greenhouse fry ecological breeding is an important basis for ensuring the healthy and stable development of the fishery industry. Among them, reasonable feeding of feed is the key link for efficient, economical and ecological breeding of fish fry. In the traditional breeding method, the bait is thrown and released mainly by manual experience, without considering the actual demand of the fry for feed and the biological carrying capacity of the water body. Blind-feed feed feeding is time-consuming and labor-intensive, and it is prone to overfeeding, which reduces the utilization rate of fertilizers, causes waste of resources, and increases economic costs; it can also cause some fish to crave food, Inhibit the nat...

Problems solved by technology

In the traditional breeding method, it mainly relies on manual experience to throw and release the bait, without considering the actual demand of the fry for feed and the biological carrying capacity of the water body

Blind-feed feed feeding is time-consuming and labor-intensive, and it is prone to overfeeding, which reduces the utilization rate of fertilizers, causes waste of resources, and increases economic costs; it can also cause some fish to crave food, Inhibit the natural growth of fish and affect the quality of fish meat

The remaining bait will also cause deterioration of the water body, increase the burden on the environment, and at the same time bring troubles for farmers to frequently replace and purify the water body
