4. Satellite remote sensing, using polar-orbiting meteorological satellites, land resource satellites, geostationary satellites, and low-orbit satellites to detect forest fires. This method has a wide range of detection, fast data collection, continuous data, and is not affected by terrain conditions. Image True, but the use of satellite remote sensing will occupy a large amount of data, and it is difficult to detect fire hazards in the early stage

Embodiment Construction

[0036] In order to overcome the defect that the existing image-based fire recognition technology is difficult to apply to the early fire recognition of transmission corridors, the present invention proposes a comprehensive recognition method for multiple characteristics of early fires using thermal imaging technology.

[0037] The infrared panoramic camera forms images according to the infrared radiation of the object, and has a wide operating band and high sensitivity. Therefore, the infrared images obtained by the infrared panoramic camera are used in the present invention. In order to comprehensively monitor the surrounding area and reduce power consumption as much as possible, a 360-degree fisheye lens is used to realize an infrared panoramic camera to obtain surrounding panoramic images. Since the power transmission corridor is located outdoors, there are many interference factors, especially the natural light contains various bands of light. In the outdoor environment wit...

Abstract

The invention discloses a mountain fire monitoring and recognizing method and device based on a 360-degree panoramic infrared fisheye camera and belongs to the technical field of forest fire monitoring and recognizing. The method is mainly characterized in that infrared images collected by the 360-degree panoramic infrared fisheye camera, the temperature value and smoke concentration are combined, processed and analyzed, wherein the temperature value and the smoke concentration are collected in a corresponding region, so that analyzed features are applied to a recognition model for recognition, and whether a fire breaks out in the monitoring region is judged. The device comprises a data acquisition module, a data control module, a data transmission module, a data processing module, a data storage module and a power management module. The mountain fire monitoring and recognizing method and device overcome the interference of natural light and the like in the fire recognition process, and the missing report rate and the false alarm rate of fires are lowered.

Description

technical field [0001] The present invention relates to the technical field of forest fire monitoring and identification near power transmission corridors, in particular to a method of combining images collected by a 360-degree panoramic infrared fisheye camera with temperature values ​​and smoke concentrations collected in corresponding areas to determine whether a fire has occurred in the monitored area A method also relates to the device used in the method. Background technique [0002] As the construction of the national power grid continues to strengthen, the number of transmission corridors will continue to increase. Some transmission corridors may have various potential safety hazards, and the impact of forest fires on them is increasing. Forest fires may lead to the downfall of power transmission corridors, resulting in huge economic losses and serious social impacts. It can be seen that the study of forest fire monitoring technology in transmission corridors is of ...
