Video sequence-based real-time fire detection early warning method
The invention provides a video sequence-based real-time fire detection early warning method. The method comprises the steps of S1, reading a frame of video sequence, and extracting a motion region ina video by adopting a frame difference method; if the motion region is not detected, returning to the...

| description | The invention provides a video sequence-based real-time fire detection early warning method. The method comprises the steps of S1, reading a frame of video sequence, and extracting a motion region ina video by adopting a frame difference method; if the motion region is not detected, returning to the step S1; S2, detecting a flame region and a smoke region at the same time, and matching motion pixel points of the motion region with a flame color feature model and a smoke color feature model, thereby identifying a flame region and a smoke region; if the flame region and the smoke region are notextracted, returning to the step S1; and S3, if the flame region or the smoke region is detected, indicating that flame or smoke occurs, at the moment, performing fire early warning, and then readinga next frame. By adopting a static and dynamic feature combination method, the flame and the smoke are subjected to double detection according to fire combustion conditions in different scenes, so that the fire detection sensi |
