SYSTEM AND METHOD FOR VIDEO BASED FIRE DETECTION

摘要

A method for recognizing fire using block-wise processing of video input provided by a video detector. Video input is divided into a plurality of frames (42), and each frame is divided into a plurality of blocks (44). Video metrics are calculated with respect to each of the plurality of blocks (46), and blocks containing the presence of fire are identified based on the calculated video metrics (74). The detection of a fire is then communicated to an alarm system.
