Infrared thermal imaging all-weather anti-pirate on-board alarming system

Abstract

The invention discloses an infrared thermal imaging all-weather anti-pirate on-board alarming system, belonging to the field of vessel anti-pirate technique. The system comprises a board inside and outside infrared photographing module, an image processing module and an alarming module, wherein the image processing module comprises an image dividing module, an image screening module and an image classifying module; an infrared image obtained by the board inside and outside infrared photographing module is input into the image dividing module to be divided so as to obtain a binary image; the binary image is further input into the image screening module to be screened so as to obtain characteristic vector information of the image; the characteristic vector information is subjected to SVM (support vector machine) classification training so as to obtain the recognition result and alarming information of the characteristics of the human body; and the alarming information is input into the alarming module to realize alarming. Depending on the integration of software and hardware, the system is stronger in self-adaptivity, good in instantaneity, low in false alarming rate and excellent in portability; and the hardware part of the system is minimized, portable, low in energy consumption and high in integration degree, and has sufficient identification processing and man-machine interaction calculation ability.

Description

technical field [0001] The invention relates to an anti-pirate night boarding and sneak attack alarm system, in particular to an infrared thermal imaging all-weather anti-pirate boarding alarm system using infrared thermal imaging technology combined with advanced computer vision processing algorithms. The invention belongs to the technical field of ship anti-piracy. Background technique [0002] Modern ships are equipped with nautical radars, capable of detecting large targets such as large ships on the water surface, icebergs, and port settings, and can provide reliable data for ship positioning, ranging, piloting, and collision avoidance. However, due to the constraints of the resolution of nautical radars, it is difficult to Detect small targets at close range. In this way, pirates can easily cross the monitoring blind spots of various instruments, approach the ship without the crew noticing, and wait for an opportunity to sneak attack; Board the ship and attack.

[0002] Modern ships are equipped with nautical radars, capable of detecting large targets such as large ships on the water surface, icebergs, and port settings, and can provide reliable data for ship positioning, ranging, piloting, and collision avoidance. However, due to the constraints of the resolution of nautical radars, it is difficult to Detect small targets at close range

In this way, pirates can easily cross the monitoring blind spots of various instruments, approach the ship without the crew noticing, and wait for an opportunity to sneak attack; boarding raid

[0003] At present, the anti-piracy boarding early warning equipment used by ships at home and abroad mainly includes active infrared camera imaging alarm system and passive infrared sensor alarm system. Obvious disadvantages: the disadvantages of the former are consistent with the difficulties faced by the crew when patrolling, and the visual distance is short, and the effect becomes worse under severe sea conditions such as heavy rain and fog; although the latter can work at night, it can only detect 10um emitted by the human body Left and right wavelengths of radiation, if the attacker changes the characteristics of the radiation wavelength through disguise, the device will fail

However, the product cannot actively identify people for automatic alarm
