A New Real-Time Fire Detection Method Based On Infrared Image

In this paper, a new flame detection method using infrared images is proposed. By analyzing the spectrum of the sun, a 940nm narrow-band filter is applied to the camera to obtain an infrared image. Then, a threshold selection method for the flame is applied to obtain the binarized image, and then the similarity of consecutive video frames and the roundness of the contour are used to make the final judgment. Experimental results demonstrated that the proposed method has the advantages of high speed, low cost, and high accuracy.
