大空间室内火灾早期自动探测与定位研究

STUDY ON THE EARLY FIRE RECOGNITION AND POSITIONING BY COLOR IMAGES IN LARGE SPACE

本文在深入研究早期火灾一般燃烧火焰在彩色影像上所呈现的光谱及运动特性基础上,首次提出利用彩色影像实时探测室内火灾的新方法,通过物方坐标与像方坐标的直接线性变换,实现了早期火灾的自动探测与空间定位,实验证明了该方法的有效性与稳健性,且具有巨大的应用前景。

Considered the specific spectrum property of early fire in the color images, a new method for detecting the early fire in large space by color images was presented. By use of Direct Linear Transformation between object coordinate system and image coordinate system, the early fire in large space can be detected and positioned automaticly. The real experiments illustrate this method is feasible and robust, it has shown that it can be widely .used in early fire detection and positioning in large space.
