Combustion object identification method, robot fire extinguishing method, and fire extinguishing robot

Abstract

The invention discloses a combustion object identification method, a robot fire extinguishing method, and a fire extinguishing robot, belonging to the field of robot fire extinguishing. The combustion object identification method includes the following steps: acquiring a video shot at the same angle in a fire scene; intercepting a frame in the video as a second image Comparing two adjacent second images, identifying the part of the second image where the change of the outer outline of the flame is less than the preset threshold as the combustion object, and identifying the combustion object by comparing the size of the change in the outer outline of the flame in the two consecutive frames of images, It can efficiently and accurately identify the burning material in the flame, which is helpful for the fire-extinguishing robot to directly aim at the burning material to put out fire, which is conducive to saving fire-extinguishing materials and improving the fire-extinguishing efficiency of the robot.

Description

technical field [0001] The invention relates to a combustion object identification method, a robot fire-extinguishing method, and a fire-extinguishing robot, belonging to the field of robot fire-extinguishing. Background technique [0002] The situation of the fire scene is very complex, with dangerous factors such as toxic gas, lack of oxygen, and high temperature. Based on this problem, experts in the field have developed a variety of unmanned fire extinguishing equipment in recent years. Specifically, robots with image recognition capabilities and spraying capabilities enter the fire field, use image recognition technology and temperature sensors to analyze the flame position, and the robot sprays on the flame position. Water realizes intelligent fire extinguishing. The method of identifying the flame position in the prior art is to first use image recognition technology to identify the flame image, measure the temperature on the spot according to the position of the fla...

Problems solved by technology

In fact, the temperature of the flame tip is the highest, and the essence of fire extinguishing is to reduce the temperature of the burning material or lack of oxygen. In the prior art, the robot sprays at the flame tip instead of directly targeting the burning material, and the fire extinguishing efficiency is low.
