基于MATLAB的火灾视频探测技术

Video Sensing Technology Based on MATLAB for Fire Accidents

基于传感器的火灾识别方法在空间广阔、布局跨度大的特定环境下难以实现火灾的有效、及时探测。提出一种基于MATLAB的火灾视频探测技术,集成火焰图像采集、火灾图像识别、火灾报警联动等模块,通过编写MATLAB函数,对火焰视频图像进行灰度处理、二值化处理、边缘检测等操作,对火焰的边缘变化、形状变化、闪动变化和面积变化等特征进行分析,提取火警信息。应用表明,基于MATLAB的火灾视频探测技术具有可靠性、准确性,能够实时计算得到火焰轨迹,为早期预警火灾的发生打下了坚实的基础。

The fire identification methods based on the sensors are difficult to realize the effective and timely detection of fire accidents in the special environment of wide space and large span.Proposed is a video sensing technology based on MATLAB for fire accidents.It integrates modules including flame image acquisition,fire image recognition and fire alarm linkage.By compiling MATLAB function,the flame video image is processed in operations including gray level,binary processing and edge detection,and the characteristics including flame edge change,shape change,flash change and area change are analyzed,as to extract the fire alarm information.The application shows that the video detection technology based on MATLAB is reliable and accurate for fire accidents.It can calculate the flame trace in real time,which lays a solid foundation for in-time prediction of whether a fire accident occurs.
