Video Smoke Detection Based on the Method of Optical Flow

摘要

with the rapid development of urbanization and the population swell，the economic loss caused by fire is rising year by year.At present, there are more and more large space places,such as the underground tunnels,large chemical plants,large warehouses etc. At present,domestic research mainly focus on the detection of flame in visual band,and fire is not the initial typical physical characteristics when fire happened,so this kind of system is hard to achieve the fire early detection. Foreign researches mainly focus on the analysis of the color of the smoke. Based on this,combining with the color of smoke and dynamic features, this paper make further research for the method of the detection of early images of fire smoke.
