Aquatic organism behavior online monitoring system and method based on electric and video signals

Abstract

The invention discloses an aquatic organism behavior online monitoring system and method based on electric and video signals. The system comprises an aquatic organism behavior sensor which integratesan electric field and a video technology into one device, and the aquatic organism behavior sensor transmits aquatic organism behavior signals collected by the electric field and aquatic organism video data collected by a camera shooting device to a computer end for processing; at the computer end, the aquatic organism video data is processed through a video print positioning algorithm to monitorthe accurate positioning of aquatic organisms. According to the algorithm, each individual is independently analyzed, corresponding pixel blocks representing multiple time periods of each individual are stripped out, a framework is built for the pixel blocks, sliding is conducted in the direction of the framework, the size of each slice is analyzed, and feature data of each individual is extracted; even if cross-fading occurs again, each individual can still be corresponded to as long as data obtained after two individuals are completely separated exists, and precise positioning is kept.

Description

technical field [0001] The invention relates to the technical field of biological monitoring, in particular to an online monitoring system and method for aquatic biological behavior based on electrical and video signals. Background technique [0002] Based on the behavior capture method of fish behavior, the fish movement intensity signal is collected through the electric field. The technology is to use four electrodes, which are paired in pairs, and the positive and negative electrodes are connected to each other to generate an electric field between the electrodes. At the same time, the electrodes are connected to the signal. The processing end is responsible for collecting changes in electric field signals. When aquatic organisms move in the electric field, they will interfere with the electric field. The signal processing end captures the changing electrical signals, thereby realizing the positioning of aquatic organisms and synchronously outputting behavior intensity dat...

AI Technical Summary

Problems solved by technology

The current technology mainly relies on the behavioral intensity index and relies too much on the change signal of the electric field, which will cause the behavioral intensity signal to not only collect fish movement, but also changes in the external environment such as water flow rate and food feeding may also change the behavioral intensity signal. In addition, it is difficult to accurately locate the specific position of the fish by simply using the electric field to monitor the motion signal, and the ability to distinguish individual fish is low, and it is easy to make misjudgments. For example, when two fish cross and merge, it is easy to separate the two fish again reverse identity
