Abstract

A method for detecting an open flame includes: acquiring a plurality of frames of first images of a suspected target in a monitoring region; acquiring gray scale change features of the plurality of frames of first images and attribute features of the suspected target based on the plurality of frames of first images, the gray scale change features being configured to indicate temperature changes of the suspected target; and determining the suspected target in the monitoring region as an open flame, if the gray scale change features of the plurality of frames of first images and the attribute features of the suspected target both satisfy an open flame condition.
