Fire detection system
The fire detection system uses frequency spectral analysis to accurately detect fires by analyzing the slope of the frequency spectrum's approximation line, overcoming environmental obstructions and specifying the fire's depth-direction position in two-dimensional images.

AI Technical Summary
Conventional fire detection systems struggle to accurately specify the three-dimensional position of a fire in a monitoring area due to limitations in capturing depth information from two-dimensional images and are susceptible to environmental factors that obstruct flame and smoke detection.
A fire detection system that performs frequency spectral analysis on consecutive images to identify the slope of the frequency spectrum's approximation line, utilizing reflections from fire flames on predetermined surfaces to determine the fire's depth-direction position, even in obstructed views.
Enables accurate fire detection by distinguishing fire-related events from non-fire events, regardless of environmental conditions, and identifies the fire's location in the depth direction within the monitoring area.
