Fire alarm based on spatial temporal analysis of fire in video

摘要

Fire alarm system is based on detection of fire from video acquisition input data. This is done with the help of digital image processing techniques and embedded vision. It is based on vision-based fire detection system. This approach integrates colour, spatial, temporal and motion information to locate fire regions in video frames. The characteristics of burning flame and spatial temporal features of smoke combination is used to remove spurious fake fire regions. This video based fire alarm systems has stages such as frame conversion, fire and smoke colour detection, motion detection, spatial temporal analysis. Fire alarm will be activated when the system detects the occurrence of fire in a certain position and time interval surpasses the threshold.
