Forest fire monitoring and early warning system based on infrared thermal imaging

Abstract

The invention relates to a forest fire monitoring and early warning system based on infrared thermal imaging. The system comprises a plurality of thermal imaging bispectral cameras, an alarm server and an alarm client. The thermal imaging bispectral cameras include infrared thermal imaging cameras and visible light cameras that are arranged in an integrated manner. The alarm server includes a dataacquisition module, a feature extraction module, and an alarm service module which are sequentially connected. According to the invention, abnormal temperature fluctuation is determined based on temperature data collected by the thermal imaging bispectral cameras and alarming is made based on the abnormal temperature fluctuation, so that the accuracy of the fire identification alarming is improved. Meanwhile, a visible light video image of the monitoring area is displayed at the alarm client; and when a fire occurs, the staff member can check the visible light video image of the monitoring area in time to understand the fire situation in the monitoring area, so that a problem that the traditional forest fire early-warning monitoring system can only watch the hot contours of people or objects through infrared images and thus fire conditions can not be obtained accurately is solved.

Description

technical field [0001] The invention relates to the field of forest fire prevention monitoring, in particular to a forest fire prevention monitoring and early warning system based on infrared thermal imaging. 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 destructive consequences to the forest. Forest fires not only burn the forests, harm the animals in the forests, but also reduce the reproductive capacity of the forests, cause soil barrenness and damage the function of forests to conserve water, and even lead to the imbalance of the ecological environment. Although science in today's world is advancing with each passing day, human beings have not yet made long-term progress in subduing forest fires. [0003] At present, the methods for early warning and monitoring of forest fire prevention in the market mainly include ground patrol, watchtower monitoring, ae...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the technical problems existing in the prior art, the present invention provides a forest fire prevention monitoring and early warning system and system based on infrared thermal imaging, which solves the problem of the traditional forest fire prevention and early warning monitoring system based on infrared temperature detectors. Improper setting of the alarm temperature threshold will cause fires. It is difficult to clearly understand the fire situation in the monitoring area because only the thermal outline of people or objects can be seen through infrared images.
