Embodiment Construction

[0043] An embodiment of the present invention provides a method for determining the speed of fire spread, including: acquiring a first image and a second image from an infrared image, analyzing the first image and the second image, and determining the position of the fire point; using image processing The method is to determine the displacement distance of the fire point from the first image and the second image, obtain the wind direction of the fire point, and determine the fire point according to the wind direction of the fire point and the imaging time interval between the first image and the second image. Spread speed. Therefore, the problems of rough grassland fire spread speed algorithm, low precision and difficult operation in the prior art are solved.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obvi...

Abstract

The invention discloses a method and a device for determining fire spreading rate, relates to the technical field of image processing, and is aimed for solving the problems of rough grassland fire spreading rata algorithm having low precision and being difficult to operate in the prior art. The method comprises following steps: a first image and a second image are obtained from an infrared image, and the first image and the second image are analyzed for obtaining a fire point position; the wind direction of the fire point is determined according to the fire point position, and the fire spreading rate is determined on the basis of the wind direction of the fire point, the imaging time interval between the first image and the second image, and the fire point position.

Description

technical field [0001] The present invention relates to the technical field of image processing, and more specifically to a method and device for determining fire spreading speed. Background technique [0002] Grassland fire is one of the important disasters that destroy the ecological balance of grassland and endanger the life and safety of grassland people. It has the characteristics of strong suddenness and great harm. [0003] In the prior art, for grassland fires, the method of determining the spread speed of grassland fires is mainly based on the simple estimation of the position close to the ignition point and the corresponding time, because the flame is a kind of energy fluid, and the spread of grassland fires is not like a simple monomer Therefore, the above-mentioned method for determining the spread speed of grassland fire has the characteristics of rough algorithm, low precision, and difficult operation. [0004] To sum up, in the prior art, there are problems ...
