Abstract

The invention discloses a forest fire detection method, which comprises the steps of acquiring a high-resolution visible light image and a low-resolution infrared light image of a detection area by using a satellite remote sensing technology; performing pixel registration on the low-resolution infrared light image by taking the high-resolution visible light image as a reference to obtain a registered image; performing pixel type judgment on each pixel in the registered image to obtain a target image of a known pixel type, wherein the pixel types comprise cloud pixels, water pixels and non-cloud water pixels; traversing pixels in the target image by using a sliding window with a preset size, and judging whether a central pixel of each window is a fire point or not; and obtaining position information of a forest fire occurrence place according to position information corresponding to the pixels judged to be the fire points. The problem of relatively low accuracy of the existing forest fire detection method is solved.

Description

technical field [0001] The present application relates to a fire detection method, in particular to a forest fire detection method. Background technique [0002] Forest fire is an important factor affecting the carbon cycle of terrestrial ecosystems. It can change the carbon cycle process and carbon distribution pattern of the entire terrestrial ecosystem. It is also one of the main disasters that endanger people's lives and property. Timely acquisition of fire point information can improve fire early warning capabilities. Because forest fires usually have the characteristics of strong suddenness, fierce fire, and fast spread, and the places where fires occur are usually sparsely populated and difficult to detect. Therefore, the use of satellite remote sensing detection has become an important way of forest fire detection. [0003] However, at present, due to the small difference between the pixels of some fire spots on the satellite image and the surrounding pixels, the a...
