Embodiment Construction

[0035] Such as figure 1 As shown, the multi-spectral and multi-scale forest fire monitoring method based on visible light-thermal infrared in the present invention utilizes the advantages of large-scale satellite remote sensing monitoring and small-scale near-ground monitoring means, through the rational configuration and mutual cooperation of the two , invent a new monitoring method, which is divided into the following steps:

[0036]Step 1: Use small-scale near-surface monitoring to automatically monitor forest fires, identify forest fires for each frame of pictures and make an initial alarm, wake up monitoring personnel for interactive forest fire discrimination, and at the same time order the camera to aim at the target and fix the scanning range, and at the same time Command the camera to scan at fixed points, continuously send back images of forest fires on site, and monitor whether the fire has not broken out or the fire has started;

[0037] Step 2: During the spread...

Abstract

The invention relates to a fire monitoring method, in particular to a visible light-thermal infrared based multispectral multi-scale forest fire monitoring method which utilizes the advantages of a large-scale satellite remote sensing monitoring means and a small-scale near ground monitoring means to invent a novel monitoring method through reasonable configuration and mutual coordination of the two means. In the invention, the spectral features as well as picture pattern and textural features of forest fire points are researched, the forest fire recognition algorithms of visible light images and thermal infrared images are organically combined, and the interference and the like on forest combustion smoke and open fire recognition, which are caused by the cloud, fog, lamplight, red substances and the like of a forest district, are eliminated, so that the visible light-thermal infrared based multispectral multi-scale forest fire monitoring method by which various factor interferences can be eliminated is invented, thus a fire alarm automatic recognition function can be achieved, the manpower cost for 24-hour manual monitoring can be greatly lowered, and the accuracy of forest fire monitoring can be effectively improved.

Description

technical field [0001] The invention relates to a fire monitoring method, in particular to a multi-spectral and multi-scale forest fire monitoring method based on visible light-thermal infrared, which combines two forest fire monitoring images of visible light and infrared to automatically identify fire and give an alarm. Background technique [0002] Forest fire is a frequent natural disaster, which causes huge loss and serious harm to forest resources, forest ecosystem and human life and property. In all aspects of forest fire disaster prevention, mitigation and relief, the most critical and core link is forest fire monitoring and alarm. Only by timely detection, alarm and appropriate fire suppression measures at the initial stage of forest fires can the fire be effectively controlled and the loss of forest fires reduced to a minimum. [0003] There are mainly four methods of forest fire monitoring at home and abroad: ground inspection, fixed-point observation of cloud pl...
