摘要/Abstract

摘要： 为研究低照度火灾场景中应急疏散标志的颜色特征变化，提出了一种基于闵氏距离的低照度颜色特征量化方法，利用统计学方法研究低照度下火场标志背景的颜色特征参数。首先分别在室内灯光环境和低照度单一火场环境中取得标志背景的图片样本；其次对试验图片进行检测统计、特征提取；最后统计并分析图像的闵氏距离、方差。试验结果表明：近火场标志背景使用效果变差，绿色和蓝色背景标志尤为明显。以非接触测量的闵氏距离方法能够有效度量各通道值，并能分析各参数对结果影响的大小。

Abstract: In order to study the color characteristic changes of emergency evacuation signs in low - illuminance fire scene, a method for quantifying low-illumination color features based on the Min’s distance is presented. The color characteristic parameters of fire scene sign background under low illuminance are studied by statistical method. Firstly, the image samples of the background were obtained in the indoor lighting environment and the low illumination single fire environment through experiments; Secondly, the test statistics and feature extraction of the experimental samples are carried out; Finally, the Min's distance and variance of the samples were analyzed.The results show that the effect of the use of the background of the near fire sign becomes worse, especially in green and blue. The non - contact measurement of the Min's distance method can effectively measure the value of each channel, and it can also analyze the influence of each parameter on the result.

Key words: low illumination, color characteristics, fire scenario; evacuation sign
