Fire - usually is expressed with smoke situation, because the traditional smoke, temperature sensing fire detection technology still has many difficult problems to solve, do not have real-time warning, so the detection method for video images for fire smoke the smoke characteristics by many experts and scholars, this paper is based on this topic, a preliminary study on the basic algorithm and some video smoke detection design. Video smoke detection (VISD) method for the decomposition of a video into every frame image, distinguish the smoke and the background image, such as color, shape, texture, combined with the image in RGB color space and the HSV color space, according to the different colors can be roughly the smoke extraction from the region, then combined with some morphological operation, expansion, corrosion, connection, get the smoke area more accurately, so it can be better to do early fire warning. 【Key words】 【Type of Thesis】 1.1.课题目的与意义 1 1.2.国内外现状 3 1.3论文结构及主要内容 5 2 关于烟雾检测的基础知识 6 2.1 烟雾的特征 6 2.1.1 火灾烟雾的静态特征 6 2.1.2 火灾烟雾的动态特征 7 2.2 颜色空间 7 2.2.1 RGB颜色空间 8 2.2.2 YCbCr颜色空间 9 2.2.3 HSV颜色空间 10 2.3 有关烟雾检测的形态学图像处理知识 12 2.3.1基本形态学操作 13 2.3.2 膨胀 14 2.3.3 腐蚀 14 2.3.4胀和腐蚀的组合 15 3 基于颜色特征的烟雾检测系统 16 3.1概述 16 3.2 基于颜色特征的烟雾检测系统 16 3.3 基于HSV颜色特征的烟雾区域分析 17 3.4 形态学烟雾区域处理 18 3.4.1 边界提取 19 3.4.2 区域填充 20 3.4.3 形态学处理流程图 21 3.5 实验结果与分析 22
