SYSTEM AND METHOD FOR VIDEO DETECTION OF SMOKE AND FLAME

摘要

A method for detecting flame and smoke using spatial analysis of video in put (40) provided by a video detector. The video input (40) consists of a nu mber of individual frames, wherein analysis is performed on each individual frame to detect and outline regions that may contain smoke or flame (42). Ba sed on the defined outline or boundary of each detected region, spatial feat ures associated with the region are extracted (52), such as perimeter/area a nd surface area/volume. The extracted spatial features are related to one an other (54) to determine the likelihood that the region contains smoke or fla me. Extracted spatial features may be related to one another using a power l aw relationship that provides an indication of the turbulence associated wit h a bounded region, wherein turbulence is a characteristic of both flame and smoke.
