Flame finding with automated image analysis

A non-transitory computer-readable medium having stored thereon computer-executable instructions configured to cause one or more computing devices to determine regions in digital infrared images that are likely to include flame by performing operations comprising:

• obtaining a series of digital infrared images of a scene;
• detecting one or more high-temperature image regions in the scene that exceed a threshold temperature based on analysis of the series of digital infrared images;
• detecting one or more turbulent motion image regions in the scene based on analysis of the series of digital infrared images;
• and
• identifying one or more candidate regions for location of flame in the series of digital infrared images based at least in part on locations of the one or more high-temperature image regions and the one or more turbulent motion image regions.

A system comprising one or more computing devices comprising one or more processors, the one or more computing devices being programmed to determine a likelihood of the presence of flame in a scene by performing operations comprising:

• obtaining a series of digital infrared images and digital optical images of a scene;
• identifying a candidate region in a location of the scene based at least in part on analysis of temperature and turbulent motion in the series of digital infrared images;
• identifying an optical image slice within an optical image region corresponding to the location of the candidate region based at least in part on analysis of the series of digital optical images;
• determining a likelihood of the presence of flame in the scene based at least in part on analysis of the optical image slice.
