FIRE DETECTION PROCEDURE AND DEVICE BASED ON IMAGE ANALYSIS.

摘要

Automatic fire detection procedure, based on the recognition of flames and / or smoke from the analysis of an image sequence, based on the analysis in several image processing algorithms, characterized in that an algorithm consists in comparing the frequency content of at least one image (31) of said sequence with the frequency content of a reference image (32), in order to detect an attenuation of the high frequencies, independently of the variations on the other portions of the spatial spectrum of the image.
