Abstract

The present disclosure discloses a fire disaster monitoring method and apparatus. The method includes: obtaining an infrared image that is obtained through photoshooting a to-be-monitored area by an infrared detection apparatus located on an aerostat, where different colors displayed in the infrared image correspond to different temperatures; determining, according to the colors displayed in the infrared image, whether a difference between temperatures corresponding to adjacent areas in the infrared image is greater than a predetermined threshold; and if it is determined that the difference between the temperatures corresponding to the adjacent areas is greater than the predetermined threshold, sending fire disaster alarm information to a receiving device, where the fire disaster alarm information is used to indicate that a fire disaster occurs in the to-be-monitored area. The present disclosure resolves a technical problem of relatively low monitoring accuracy caused because a prior-art fire disaster monitoring method is used.
