Problems solved by technology

However, the system uses remote sensing technology. Although it has a wide detection range, it cannot detect small-scale fires, and the early warning efficiency is not high enough, so that firefighters cannot extinguish the fire at an early stage.

Abstract

The invention provides a forest fire detection and early warning system based on computer vision, which comprises a central service station, a video acquisition module, a video storage module, a picture comparison module, an acquisition control module, a depth analysis module and a communication module, and is characterized in that the video acquisition module is used for acquiring image data around a forest early warning station; the video storage module is used for storing a contrast picture group, the picture contrast module is used for comparing the contrast picture group with real-time image data to obtain a suspicious area, the acquisition control module controls the video acquisition module to obtain a detail picture of the suspicious area, the depth analysis module performs flame recognition on the detail picture, after the flame is recognized, the communication module sends image data to the central service station. According to the system, the flame detection is divided into two levels of image contrast and deep analysis, the initial fire behavior can be accurately detected under limited computing resources, and the loss caused by the fire is reduced.

Description

technical field [0001] The invention relates to the technical field of forest fire detection, in particular to a computer vision-based forest fire detection and early warning system. Background technique [0002] Forest fire is the most dangerous enemy of the forest and the most terrible disaster of forestry. It will bring the most harmful and devastating consequences to the forest. Forest fire not only burns the forest, harms the animals in the forest, but also reduces the The ability to regenerate the soil causes the barrenness of the soil and destroys the role of forest water conservation, and even leads to an imbalance in the ecological environment. How to effectively identify the fire at the initial stage of the fire, so as to make early deployments for inactivation, and reduce the losses caused by fire? Problems facing fire warning systems. [0003] Many fire early warning systems have been developed. After a large number of searches and references, we found that the ...
