Nighttime Video Smoke Detection Based on Active Infrared Video Image

摘要

Compared with traditional methods, video smoke detection has many advantages, such as fast response, noncontact and so forth. For the sake of detecting smoke in the nighttime with 0 lux around, the paper presents a smoke recognition method based on active infrared CCD video image. Experimental results show that it can well recognize smoke to reach the aim of smoke-detection in the nighttime, by extracting the feature that smoke reveals while the plume of smoke upwards, analyzing feature values, studying smoke recognition methods and comparing with the interferences.
