摘要
通过模拟火灾实验,利用移动的CCD摄像头实现图像的动态获取与传输.重点研究火焰图像的阈值处理、边缘检测、链码提取等图像处理算法,并且运用Matlab语言编程处理实验图像,计算出火焰图像的面积、周长、圆形度等特征值,从而总结得出火灾发生时具有火焰面积增大、边缘抖动等特征,获得了早期火灾探测的重要判据.
Fire experiments were conducted and the flame images were gathered dynamically by a moving CCD camera. The algorithms of threshold processing, edge extraction and boundary chain code abstraction were studied. By programming with Matlab software, the features of fire, such as the flaming area becoming larger with the fire and fire edge fluctuation were summarized. The criteria of early fire detection is extracted.
