Problems solved by technology

[0003] Most of the existing forest fire prevention and pyrotechnic recognition and alarm technologies use the preset position method for alarming, that is, after the pan / tilt moves to a fixed point for static image recognition, it enters the next fixed point and repeats the action of pyrotechnic recognition. It will cause problems such as long recognition time, inflexibility, and dead angles; how to form a technology that can perform dynamic pyrotechnic recognition has become an urgent demand

Embodiment Construction

[0045] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0046] like Figure 1~2 As shown, a forest fire prevention smoke identification method mainly includes the following steps:

[0047] Obtain thermal imaging image information and visible light image information of the forest;

[0048] Preprocessing the visible light image information and the thermal imaging image, extracting features of the thermal imaging image, judging the visible light image information as daytime image information or nighttime image information and feeding back, extracting the daytime image information respectively Image information or features of the night image information; pre-processing includes performing image size processing, denoising processing, color processing, texture processing, etc...

Abstract

The invention relates to a forest fire prevention pyrotechnics identification method and system, and the method comprises the following steps of acquiring thermal imaging image information and visiblelight image information of the forest; preprocessing and extracting features of the visible light image information and thermal imaging images, determining and feeding back the visible light image information as daytime image information or night image information; determining whether there is a high temperature area according to the thermal imaging image information, determining whether the temperature of the high temperature area continuously rises; determining whether there is smoke in the cruise area according to the visible light image information, marking a suspected smoke area; comparing the suspected smoke area with a pre-stored smoke feature point library to determine whether it is a pyrotechnic area; performing static image recognition and alarming on the high temperature regionwhere the temperature continuously rises and / or the cruise region where the pyrotechnic region exists. The method provided by the invention performs all-weather cruise identification on forest fireworks, timely reports the fireworks area found, has high recognition accuracy and timely alarm, and greatly reduces losses caused by forest fires.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a method and system for forest fire prevention fireworks recognition. Background technique [0002] At present, the forest fire prevention early warning technology mainly focuses on the two physical quantities of light and temperature. In forest areas with dense trees, only smoke can appear in the monitoring line of sight in the early stage of fire. How to use a method to realize the pyrotechnics of fire? Reporting to the police has become a kind of urgent need and has important significance for timely extinguishing of forest fires. [0003] Most of the existing forest fire prevention and pyrotechnic recognition and alarm technologies use the preset position method for alarming, that is, after the pan / tilt moves to a fixed point for static image recognition, it enters the next fixed point and repeats the action of pyrotechnic recognition. It will cause problems such as long reco...
