基于等效椭圆特征的红外热像仪火灾检测

摘要

Self-propelled intelligent positioning fire-fighting gun is a kind of intelligent fire-fighting robot designed for petrochemical industry. For the fire detection of this kind of fire-fighting robot, a fire detection system based on equivalent elliptical feature of infrared thermal imager and support vector machine (SVM) was proposed. The system uses the highest temperature feature in the gray image of infrared thermal imager as the initial judgment for the fire.Then the image is segmented by the region growing method to extract a suspected fire region. Finally, the equivalent elliptical characteristics of the suspected fire area are extracted, and the fire detection process is completed by SVM. The experimental results showed that the system can quickly and effectively detect fires in petrochemical places and has good environmental adaptability.%自行式智能定位消防炮是一种适用于石油化工场所的智能消防灭火机器人,针对该类消防机器人的火灾检测,提出了一种基于等效椭圆特征和支持向量机(SVM)的红外热像仪火灾检测系统.该系统利用红外热像仪灰色图像中的最高温度作为火灾的初始判断依据,通过区域生长法对图像进行分割,提取疑似火灾区域,提取疑似火灾区域的等效椭圆特征,并利用SVM完成火灾检测过程.实验结果表明,该系统能对石油化工场所火灾进行快速、有效检测,并有良好的环境适应性.
