Computer vision technique based method and system for detecting and extinguishing fire disaster intelligently

Abstract

The invention relates to a computer vision technique based method and a system for detecting and extinguishing a fire disaster intelligently, which belong to the technical field of fire monitoring and self-extinguishing. The method comprises the following steps: (1) using a sub-station control module to perform the fire monitoring; (2) under the condition that flame exists, estimating the spatial position of the flame through a binocular parallax technique; (3) according to a fire monitor open rule, determining an opened fire water monitor; (4) obtaining the position of the tail end of an ejecting water column of the fire monitor, namely the position of a water-drop point, by using the computer vision technique or an image processing technique; (5) adjusting the fire monitor according to the relative positions of the water-drop point and the flame to achieve the closed-loop control to the fire monitor so as to perform extinguishing; and (6) determining that the extinguishing is finished according to monitored images, and then closing the fire monitor. The method and the system can achieve the real-time monitoring and the self-extinguishing of an outdoor large space fire disaster.

Description

technical field [0001] The intelligent fire detection and extinguishing method and system based on computer vision technology of the present invention belong to the technical field of fire monitoring and automatic fire extinguishing. Background technique [0002] Fire is one of the most common serious disasters in human society. According to the fire statistics of the United States, Japan and the European Union in recent years, the direct economic loss of fire in developed countries accounts for 0.2% to 0.3% of the gross national product. Fire fatalities in the US are 0.0016%, in the EU 0.0013%, and in Japan 0.0012%, including many major fires. For example, the fire caused by the Great Hanshin Earthquake in Japan in 1995 killed more than 5,200 people. In 1997, a fire broke out in the holy city of Mecca in Saudi Arabia during Ramadan, killing more than 1,000 people. In June 2002, the forest fire in Arizona State, USA was out of control, which shocked the astronauts on the s...

Problems solved by technology

In the case of long-distance shooting, it is difficult to determine the spatial position of the fire monitor's water drop point, especially it is also easily affected by environmental factors such as wind direction. Point
