Problems solved by technology

However, in the technical solution in this patent, if the fire area is too far away from the camera, when the visible light camera or the infrared camera does not capture the fire point, the infrared image and the visible light image will not be able to establish a mapping, making the recognition accuracy in the fire recognition process low. , prone to false alarms, so it is necessary to improve the existing forest fire identification method based on multi-spectral forest fire identification method, so as to improve the accuracy of forest fire identification, so as to better identify forest fires and detect them early Forest fires, reducing losses

Embodiment Construction

[0047] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0048] combine figure 1 Shown, the forest fire identification method based on multispectrum of the present invention, comprises:

[0049] Step 1: Use a visible light camera to obtain a visible light image of the scene; use a near-infrared camera to obtain a near-infrared image of the scene.

[0050] In the embodiment of the present invention, the visible light camera and the near-infrared camera can be industrial cameras already on the market, or cameras dedicated to monitoring, etc., which can be selected according to needs.

[0051] A visible light camera is used to shoot a forest scene to obtain a visible light image, usually a color image, and a near-infrared camera is used to shoot a forest scene to obtain a near-infrared image, which is usually a black-and-white image. Moreover, in the embodiment of the present invention, the monitoring wavelength ran...

Abstract

The invention discloses a multispectral-based forest fire identification method, system, program and storage medium, belonging to the technical field of forest fire prevention. The present invention first obtains the visible light image and the near-infrared image of the scene; and identifies the suspected fire area in the visible light image and the suspected fire area in the near-infrared image; and compares the suspected fire area in the visible light image with the suspected fire area in the near-infrared image Matching, the initial verification of the forest fire situation in the scene; synchronously adjust the focal length of the visible light camera and the near-infrared camera, and re-match and verify the suspected fire area in the visible light image and the suspected fire area in the near-infrared image; Finally, perform cloud recognition verify. The invention effectively improves the accuracy of forest fire identification and reduces false alarms.

Description

technical field [0001] The invention belongs to the technical field of forest fire prevention, and in particular relates to a multi-spectrum-based forest fire identification method, system, program and storage medium. Background technique [0002] Forest fire is a sudden and destructive natural disaster that is difficult to deal with and rescue. The annual losses caused by forest fires in the world are incalculable. Forest fires have caused serious threats to forest ecology, the earth's environment, and human life and property. Therefore, it is particularly important to detect forest fire dangers early and deal with them early. However, because the forest area is relatively large and the environment is relatively complex, it is difficult to meet the demand simply relying on artificial detection of forest fires. Therefore, in order to identify fires more accurately, many fire identification methods have been proposed in the prior art. It is mainly through the method of image...
