Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, the thermal imaging video dual-appreciation forest fire identification system mainly includes a thermal imaging camera, a video camera and a processing unit. Both the thermal imaging camera and the video camera transmit images to the processing unit, and both the thermal imaging camera and the video camera are located in On the cloud platform. The processing unit includes a thermal imaging analysis unit and a video image analysis unit; the thermal imaging analysis unit is used to judge whether it is a forest fire heat source or a vehicle heat source according to the shape change, light and dark rhythm and movement of the heat source image; the video image analysis unit includes smoke detection Unit and fire detection unit, the smoke detection unit is used to judge whether there is smoke according to the extended motion characteristics...

Abstract

The invention discloses an identification method of a thermal imaging and video double-identification forest fire identification system. The identification method comprises steps of performing polling on forest regions capable of being monitored by means of a low-speed polling function of a cloud head; judging whether abnormal heat resources exist by detecting the grey value of a thermal imaging image through a processing unit; when the temperature displayed in a thermal imaging image is higher than 600 DEG C and the region area is larger than ten pixels, exiting a polling mode, analyzing questionable heat sources in the thermal imaging image regions, judging probability of the questionable heat sources becoming fire, analyzing the image in a video image region and judging types of fire. The identification method of the thermal imaging and video double-identification forest fire identification system is simple, feasible, high in identification accuracy, low in false declare and alarm rate, capable of detecting forest fire during low-speed polling and completely eradicating non-detection zones instead of fixed-point inspection in a preset position method, and good in practicability.

Description

[0001] The patent of the present invention is a divisional application of a patent with an application date of 2012-09-10, an application number of 201210331547.0, and a patent name of a thermal imaging video dual-appreciation forest fire identification system and its identification method. technical field [0002] The invention relates to a forest fire identification system, in particular to an identification method of a forest fire identification system with thermal imaging and video dual-appreciation. Background technique [0003] At present, in the field of automatic identification of fire alarms, image recognition technology or thermal imaging technology is often used to realize fire alarm detection and alarm. The use of image recognition technology for fire detection refers to the use of surveillance video, according to the characteristics of smoke or fire in the video and image, using image processing technology to identify a fire detection method. In order to improve...
