摘　　要：在基于图像的火灾探测技术中,数字图像处理是核心。将视频转换为图像之后,首先进行滤波等预处理,然后对图像进行分割即将图像中的目标与背景进行分离,以找出目标对象,通过边界跟踪获取目标轮廓及边界链码,在此基础之上提取目标的面积变化率、尖角数和圆形度等特征对目标进行分析,以判断该目标是火灾现象还是疑似火灾现象或是非火灾现象。Digital image processing plays a core role in the fire detection technology based on image. The target object will be found out after a successful convert from video into image,the preprocessing such as filtering,the image segmentation i. e. the target of the image is segmented from the background. On the basis of a target contour and a boundary chain code obtained through the boundary tracking,the characteristics of the target rate extraction,the number of sharp corners and the circular degree of the area are analyzed to determine whether the target is fire phenomenon,a suspected fire or non-fire phenomenon.

关 键 词：图像处理 火灾探测 边界链码 图像特征
