Fire detection, positioning and extinguishing method and device based on panoramic camera

Abstract

The present invention relates to a method and device for detecting, locating and extinguishing a fire based on a panoramic camera, comprising: 1) a 360-degree panoramic camera sends the captured panoramic image to an image processing system; 2) the image processing system calculates the binarization of the panoramic image Threshold T1; 3) Judging whether there is a flame area in the panoramic image according to the binarization threshold T1; 4) Binarizing the panoramic image with T1 as the threshold to the binarized image; 5) Searching for the maximum value in the binarized image The area A of the connected region, if the area A≥T2, then enter step 6), otherwise return to step 1); 6) extract the coordinates of the center point of the largest connected region, and convert it into the polar radius and polar angle of the polar coordinate system; 8 ) Use the polar angle and the vertical rotation angle as the horizontal and vertical rotation control angles of the electronically controlled fire water cannon to control its rotation; 9) Start the electric fire water cannon to spray water jets to extinguish the fire; 10) When the flame is extinguished, the electric control Go to step 1) after the monitor is reset.

Description

technical field [0001] The invention relates to a fire-fighting method and device, in particular to a panoramic camera-based fire detection, positioning and extinguishing method and device suitable for large automated outdoor spaces, and belongs to the technical field of fire monitoring and automatic fire extinguishing. Background technique [0002] In today's society, fire has become a disaster that seriously threatens the survival and development of human beings. It has the characteristics of large time and space span, high frequency of occurrence, serious loss and harm. The automatic positioning fire water monitor is an effective fire-fighting equipment for extinguishing fires in large spaces. It usually cooperates with various fire detection equipment to form a large-space fire extinguishing system. The research on fire water cannons started earlier in foreign countries than in China. As early as 1956, Edwards of the United States invented the remote control fire turret,...
