Ship illegal fishing behavior discrimination method based on binocular holder camera and ship illegal fishing behavior discrimination system based on binocular holder camera

Abstract

The invention relates to a ship illegal fishing behavior discrimination method based on a binocular holder camera and a ship illegal fishing behavior discrimination system based on the binocular holder camera. Firstly the illegal fishing alarm rules are set and the target region is set by using the unmanned ship technology; then the ship behavior in the target region image acquired by the binocular holder camera is detected through image feature point extraction and the binocular ranging technology; and then a shipboard monitoring server judges whether the ship in the acquired image is illegalaccording to the set illegal fishing alarm rules and the positioning system and transmits the alarm information and the illegal fishing image to a shore-based monitoring server through a wireless transmit-receive terminal. Existence of the illegal fishing behavior in the target region is automatically discriminated by using the binocular ranging technology and feature point extraction and then the related alarm information and the target region image are transmitted to provide the objective decision basis for the law enforcement personnel and the law enforcement department so as to solve theproblem of difficulty of fishery supervision.

Description

Technical field: [0001] The invention belongs to the technical field of marine fishery illegal fishing supervision, and relates to a method and system for judging illegal fishing behavior of ships based on a binocular pan-tilt camera. Background technique: [0002] In recent years, due to various reasons, the healthy development of the fishery has been threatened. One of the reasons that cannot be ignored is that illegal fishing activities are becoming more and more rampant, and illegal fishing methods are becoming more and more modern. It not only causes an imbalance in the structure of fishery resources, destroys the ecological environment of water areas, challenges the sustainable development of my country's fishery resources, but also seriously hinders the process of my country's ecological civilization construction. [0003] Traditional fishery law enforcement combines law enforcement boat patrols with public reporting. This method of law enforcement is costly and inef...

AI Technical Summary

Problems solved by technology

The method and system, by carrying the system on the unmanned ship, combined with actual law enforcement experience, using binocular ranging technology and image feature extraction, can automatically determine whether there is illegal fishing in the target area, and then issue relevant alarm information and target area images. , provide objective decision-making basis for law enforcement personnel and law enforcement departments, so as to solve the difficult problem of fishery supervision
