The invention provides a large-range fire disaster analyzing and
early warning system which comprises a fire disaster characteristic
database, a
video capture module, a temperature collection module, a
video quality improvement module, a fire disaster characteristic extraction module, a fire disaster characteristic identification module, a fire disaster management and control trigger rule judgment module and a fire disaster real-
time management and control platform, wherein the fire disaster characteristic
database comprises a
smoke /
flame image model; the
video capture module is used for capturing
digital video images within a
large range; the temperature collection module is used for collecting temperature information through a thermal imaging product; the
video quality improvement module is used for carrying out quality improvement on the
video image; the fire disaster characteristic extraction module is used for carrying out foreground extraction, target matching and target classification on a
video sequence; the fire disaster characteristic identification module is used for comparing and identifying a video object with the fire disaster characteristic
database according to parameters set by a user; the fire disaster management and control trigger rule judgment module is used for judging whether a rule is broken or not according to the rule preset by the user by combining video characteristics and temperature values, and if so, sending out abnormal information; and the fire disaster real-
time management and control platform is used for receiving a video analysis result and issuing a management and control order according to the analysis result.
