Study on Source Locating Technology of Visible Fire Detection in Large Space Building

Abstract

Locating fire source position is a significant aspect of automatic fire detection since it plays an important role in extinguishing fire in large space building in a short time. On the basis of previous literatures of visible fire location detection through analyzing the features of fire images, binocular vision based fire source spatial location is proposed in accordance with the computer vision principle in this paper. The binocular vision location algorithm is employed to identify the fire source position. To reach this, three typical spatial positions of fire source are measured in terms of camera scanning firstly; Secondly, confidence coefficients are added into the measured data to obtain the accurate position of fire source. Finally, the amount of water in cannon is adjusted to the right direction to put out the fire.
