| 摘 要： | 针对火灾早期预警和危险化学品气体泄漏的在线检测问题,提出了一种基于视频的早期烟雾检测新方法.整个检测过程主要由四部分组成:1)RGB分量运算参数的离线学习;2)用RGB分量运算+位屏蔽,实时分割出类似烟雾区;3)用在背景维护下的减背景来消除场景中静态的类似烟雾区干扰,再由小波变换去除场景中动态的类烟雾区干扰;4)通过长序列的多帧证据积累分析,判别标记出真正烟雾.实验表明,该方法对于320×240分辨率彩色视频的分析判别速度可迭16~20fps,并可在3~4 s内准确判别出动态场景下的核心烟雾区,且不受大空间、开放环境的限制,具有较强的误报免疫能力.

| Abstract: | A novel method to detect early smoke is presented by processing the video for fire-alarming and gas leak-alarming.The whole detection procedure is mainly composed of four parts:1) off-line learning of the operation parameters of RGB color components;2) RGB color components operation combined with bit-masked color reduction to extract the smoke-like regions in real time;3) the background subtraction by background updating to remove those static disturbing regions,and then,the wavelet-analysis after the RGB c... |
