Methods, equipment, systems for detecting fire dynamics, electronic devices and storage media

Abstract

The invention relates to methods, devices, systems for detecting fire activity, and electronic devices. This method includes: acquiring visible light images of a high-temperature target (SI01), where the high-temperature target is a target within the monitored scene that has a temperature higher than a pre-set temperature threshold, as determined by the infrared light signal received from the monitored scene; When a high-temperature target is defined to meet the combustion dynamics condition and / or not meet the infrared light source condition in the visible light image, then it is determined that a fire has occurred at the high-temperature target (SI02), the combustion dynamics condition is that a pre-set fire occurs at the high-temperature target, the infrared light source condition is that the high-temperature target is a pre-set infrared light source, The infrared light source is pre-set to emit infrared light even when no fire is occurring. Based on temperature determination, and possibly information provided by visible light, it can be determined whether the cause of high temperatures is a fire, thereby reducing the rate of false alarms in complex applications.
