Problems solved by technology

However, due to the great uncertainty of the color and shape of the flame, the monitoring device cannot distinguish the light sources such as the sun, the moon, lightning, and car lights from the flame in the early stage of the fire, and it is easy to misreport the danger

Embodiment Construction

[0043] The embodiments will be described in detail below in conjunction with the accompanying drawings.

[0044] figure 1 It shows a work flow diagram of an image-based fire recognition system of the present invention, and a kind of image-based fire recognition system of the present invention includes: a CCD camera, which rotates 360 degrees around the installation pole to collect forest images in real time .

[0045] The CCD camera rotation control unit is used to control the rotation speed of the CCD camera.

[0046] The image acquisition unit acquires the current image of the video monitoring area of ​​the CCD camera.

[0047] The brightness identification unit identifies whether there is a bright object in the current image. When a highlighted object is recognized, the CCD camera rotation control unit controls the CCD camera to stop rotating, and the CCD camera aims at the location of the highlighted object to continuously shoot images.

[0048] The speed measuring uni...

Abstract

The invention provides an image-based fire identification system and method. A CCD camera is adopted for real-time acquisition of surrounding images. A brightness identification unit recognizes the brightness of the images and judges whether there is a highlight object. When the highlight object is detected, a velocity unit is adopted to calculate the moving speed of the highlight object. Information such as weather data, the geographic coordinate of the CCD camera, the rotation angle of the CCD camera, the local time of a place where the CCD camera is located are utilized to judge whether thehighlight object is a flame or not.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an image-based fire recognition system and method. Background technique [0002] Due to sparsely populated forest areas, it is difficult for people to detect fires in the early stages. Several major forest fires in the history of our country were discovered only after the fires spread to a certain scale. Due to the rugged mountain roads, lush vegetation, and inconvenient transportation in forest areas, it is difficult to transport fire-fighting equipment to the fire scene, which brings great difficulty to forest fire fighting. [0003] At present, the main working principle of forest fire monitoring based on video technology is to analyze the color and brightness of the image after obtaining the video image, so as to judge whether there is a fire. However, due to the great uncertainty of the color and shape of the flame, the monitoring device cannot distingu...
