Abstract

An embodiment of the invention discloses a double-spectrum forest fire disaster monitoring method and a double-spectrum forest fire disaster monitoring device based on an infrared-visible light image. The double-spectrum forest fire disaster monitoring method comprises the steps of acquiring an infrared image and a visible light image of a current scene; determining a suspected fire point mark area in the infrared image; mapping the suspected fire point mark area to a corresponding position in the visible light image, and obtaining an interested area in the visible light image; verifying an image in the interested area, and determining whether a real fire point exists in the current scene according to a verification result. According to the double-spectrum forest fire disaster monitoring method and the double-spectrum forest fire disaster monitoring device, advantages in infrared image identification and advantages in visible light image identification are combined, and an interference caused by objects which have appearances similar with flame and radiation energy that is different from that of the flame to determination result can be prevented, thereby improving accuracy. Furthermore only the image in the interested area in the visible light image is verified, thereby reducing calculation amount, improving efficiency and ensuring high real-time performance in fire disaster monitoring.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile devices, and in particular to a dual-spectrum forest fire monitoring method and device based on infrared-visible light images. Background technique [0002] Forest fire is a natural disaster that is sudden, destructive, and difficult to deal with. Therefore, in the monitoring of forest fire danger, the timeliness and accuracy of finding danger are particularly important, so that relevant staff can take rescue measures as soon as possible to minimize the loss of forest fire. [0003] At present, the fixed-point observation of the cloud platform is the main forest fire detection method adopted in our country. In order to save manpower, the automatic detection technology of video images is usually used to monitor the forest fire situation. Common video image automatic detection technologies include fire point detection technology based on visible light images and fire point dete...
