早期火灾火焰尖角计算算法的研究

图像型火灾探测技术相对于传统火灾探测方法有诸多优势,适合大空间、大面积或野外环境,恶劣环境等条件下火灾的探测。早期火灾的判别多采用多个判据,如火焰面积,边缘变化等。火焰尖角数目和圆形度是早期火灾火焰的重要边缘特征。各识别判据的准确计算可以得到更加准确的火灾识别效果。通过火焰面积和圆形度两个判据判断火灾还存在一定的误判。火焰尖角数目配合其它两个判据可以有效地提高火焰的识别准确性,减少误判。

The Calculation Algorithm of Flame Sharp Angle for Early Fire

Compared to conventional fire detection,Image-based fire detection technology has many advantages.It's suitable for large space and large area or field environment,and poor environmental conditions.Multiple criterions are used for early fire,such as the area of flame,the edge of change.The number of flame sharp cusp and degree of circularity are important features of the flame.The accurate calculation of the various identification criteria could lead to more accurate effect of fire recognition.There is stil...
