Video image processing-based fire detection system and detection method

Abstract

The invention discloses a video image processing-based fire detection system and detection method. A video acquisition module, a fire detection module, a fire analysis module, a fire judgment module and a fire alarm module are connected with one another so as to form the video image processing-based fire detection system; the video acquisition module acquires video images in the coverage area of a camera; the fire detection module performs background modeling and background updating on the video image and detects a foreground moving object; the fire analysis module analyzes the video images to identify a suspected flame region and extracts static characteristics and dynamic characteristics of the suspected flames; the fire judgment module adopts the static characteristics and dynamic characteristics of the suspected flames extracted by the fire analysis module as the input of a BP neural network so as to judge whether flames exist in a video; and the fire alarm module judges whether to give an alarm according to the output result of the fire judgment module. With an existing monitoring system used in combination, the video image processing-based fire detection system can decrease detection cost and greatly reduce a false alarm rate with fire detection accuracy ensured.

Description

technical field [0001] The invention relates to a fire detection system and a detection method, in particular to a fire detection system and a detection method based on video image processing. Background technique [0002] The economic loss caused by fire in modern life is very serious, and it greatly endangers the personal safety of human beings. Safety accidents such as high-rise building fires, forest fires, tunnel fires, and public transport fires are particularly prominent. When traditional fire detectors (smoke-sensing, temperature-sensing, etc.) detect the above-mentioned fires, the reaction time is too long and the false alarm rate is high, which is not conducive to the timely detection of fires. [0003] In modern times, with the development of computer technology and the maturity of video processing technology, video-based fire detection technology has also become an important method for detecting fire. However, due to the novelty of this technology and the high ...

Problems solved by technology

However, due to the novelty of this technology and the high cost of popularization in actual work, it is not widely used in practice. Those who have already applied this technology are also exposed to environmental and suspected flame disturbances during the implementation process. Influenced by the influence, there is also the disadvantage of high false alarm rate
