Intelligent greenhouse fry feeding device based on machine vision technology and method

Abstract

The invention provides an intelligent greenhouse fry feeding device based on a machine vision technology and a method, and belongs to the technical field of greenhouse fry breeding and feeding. According to the intelligent greenhouse fry feeding device and the method, cameras are arranged on the inner wall of a culture pond and right above a feeding area to collect fish school video information, the fish school video information is transmitted to a digital signal processor to be preprocessed so as to acquire clear fish school images, the clear fish school images are sent to a server to be processed so as to acquire fish school optical flow motion trails, the fish school optical flow motion trails are input into a judgment model, then the current feeding state of the fish school is judged,accordingly, an instruction is issued to a PLC, the working states of a stock bin packing auger, a conveying packing auger and a draught fan are controlled, and accurate variable feeding is realized;the whole feeding process is more intelligent, manual participation is not needed, manpower and material resources are saved, and good economic benefits are achieved; and the scientific and reasonablefeed feeding amount and feeding time can be determined, the feed cost is saved, intelligent and accurate variable feeding of fry breeding production is realized, and the process of efficient breeding, economic breeding and ecological breeding of fishery production is promoted.

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
